Extension talk:DynamicPageList3

Algorithmix: /* original documentation is available again */ new section

== "&" character in pagename causes page not listed in dpl ==
I have a DPL3 query to list all subpages within the same namespace and category = name of current page:
<pre>
{{#dpl:
|noresultsheader= 
|category={{PAGENAME}}
|namespace={{NAMESPACE}}
|allowcachedresults=false
|format=,\n* [[%PAGE%|²{SUBPAGENAME:%TITLE%}²]],,
|ordermethod=titlewithoutnamespace
}}
</pre>
This works as expected, except when the pagename of the current page contains an "&". Then this list is always empty..I assume that the "&" in PAGENAME is interpreted as a logical AND? Is there a way around ?

==Installation==
<code>require_once "$IP/extensions/DynamicPageList3/DynamicPageList3.php";<code> doesn't reflect the actual naming in the source archive. It's actually named <code>DynamicPageList.php</code> and not <code>DynamicPageList3.php</code>.

== includeonly,onlyinclude tags ==
Is there any way to get DPL to account for these tags when it includes content through a template? --[[User:Nad|Nad]] ([[User talk:Nad|talk]]) 19:33, 9 July 2015 (UTC)
: Quite possibly. Do you happen to have a working live example of where it is broken? I can not seem to reproduce it exactly as described. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 20:31, 9 July 2015 (UTC)
::I just set up an example for you in my public wiki, but it's working perfectly! The problem I'm having is on an intranet so I can't show you, but it doesn't matter now as it must not be DPL3 that's causing the trouble. --[[User:Nad|Nad]] ([[User talk:Nad|talk]]) 14:47, 10 July 2015 (UTC)
::: Check if you have an extra opening or closing includeonly/noinclude/onlyinclude tag somewhere in the template you are working with. I have done that before and Mediawiki's parser does not produce an error. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 20:15, 10 July 2015 (UTC)

== DPL not installed on gamepedia.com ==
A lot of the manual examples in gamepedia.com aren't making much sense because they use actual DPL statements to show the results of the examples, but DPL isn't installed so the result of the example syntax is the same text as the example itself. --[[User:Nad|Nad]] ([[User talk:Nad|talk]]) 14:59, 12 July 2015 (UTC)
:Looks like I never actually copied/ported over the examples from the old manual. The examples on the individual documentation pages are intended to be plain text. I will work on porting and/or creating examples. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 16:10, 20 July 2015 (UTC)
:: This is still a work in progress, but progress is being made. There were some bugs in 3.0.1 that I encountered that were actually preventing the manual from progressing forward. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 20:14, 29 July 2015 (UTC)

== HitCounters ==

[[Manual:$wgDisableCounters|HitCounters]] were removed in 1.25 and moved into an [[Extension:HitCounters|extension]]. Since installing the extension deletes the relevant tables, which is also scheduled to happen in 1.26 for all installs, reports that use the counters throw database errors. -- [[User:Prod|Prod]] ([[User talk:Prod|talk]]) 02:00, 21 July 2015 (UTC)
: The new release of [[Extension:DynamicPageList3]] supports the HitCounters extension now and resolves this issue. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 20:14, 29 July 2015 (UTC)
::It doesn't seem to be working for me. I got the following error: Unknown column 'hit_counter.page_counter' in 'order clause'. -- [[User:Prod|Prod]] ([[User talk:Prod|talk]]) 02:22, 11 August 2015 (UTC)

== suppresserrors/debug, undefined variable ==

Many thanks for this great re-work! DPL has become so essential to my wiki that I went through the trouble of upgrading to MW 1.24 and lifting PHP to 5.4. I am truly glad to see that this extension is being maintained in good hands.

I am using version 3.0.2 which I cloned via Git IIRC. Two things I noticed:

# Instead of "suppresserrors = true" I had to set "debug = false" in addition.
# There seems to be a small bug in the code for I am getting "Notice: Undefined variable: where in /var/www/extensions/DynamicPageList/classes/Query.php on line 1816".

: I am looking into suppresserrors/debug issue. However, the PHP notices are fixed as of: https://github.com/Alexia/DynamicPageList/commit/3b8c52336cde5c444e7cd21d675d1dc802b681c0 [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 15:23, 31 July 2015 (UTC)
:: Took a few minutes to figure out, but the issue with suppresserrors is that it is deprecated. Setting [http://help.gamepedia.com/DPL:Parameters:_Controlling_Output_Volume#noresultsheader noresultsheader] to a blank space will have the same effect of suppressing errors for queries. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 15:43, 31 July 2015 (UTC)

: Many thanks for your quick response! In my original request I forgot to mention that the [http://help.gamepedia.com/DPL:Parameters:_Controlling_Output_Volume#suppresserrors wiki page about suppresserrors] mentions debug but that is a red link. It would be great if that could reference could be completed. Cheers! --[[User:Sm8ps|Sm8ps]] ([[User talk:Sm8ps|talk]]) 19:29, 31 July 2015 (UTC)

== dplcache parameter ==

When is going to be introduced a replacemenet for the 'dplcache' parameter? Or is there already one? The documentation on gamepedia says that it's being worked on. Is there a release date or... ? [[Special:Contributions/188.24.73.36|188.24.73.36]] 14:22, 15 November 2015 (UTC)
: Whoops, that should have been removed from the documentation. The dplcache parameter was added in DPL2 and I removed it when creating DPL3. The cache functionality is now fully handled by MediaWiki's built in cache system and there is no need for it anymore. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 17:35, 15 November 2015 (UTC)
::Hmm, then how can I make it so whatever it's displaying (images in my case) changes only once per day and not every time I reload the page? I am using both <code><nowiki>|allowcachedresults=true</nowiki></code> and <code><nowiki>|cacheperiod=864000</nowiki></code>. [[Special:Contributions/188.24.73.36|188.24.73.36]] 13:48, 16 November 2015 (UTC)
:::Allowcachedresults=true is the default. Caching is is explicitly turned on and has to be disabled(set to false) in DPL3 so it is not needed to specify the allowcachedresults parameters. This is opposite of DPL2. The usage of cacheperiod is still correct, but you have an extra zero for the number of seconds. Otherwise the default is one hour. [[User:Alexia E. Smith|Alexia E. Smith]] ([[User talk:Alexia E. Smith|talk]]) 15:07, 16 November 2015 (UTC)
::::Welp, I have removed both the extra zero and the unnecessary parameter, but it's still showing a different image each time the page is reloaded. Is there a tag that makes it change the image only once per day? Also, does this separator <code>¦</code> separate titles both in 'notcategory' and 'nottitlematch'?

== Setting $allowUnlimitedResults=true makes no change of count limit of 500 ==

I want to count the number of members in a category by using

{{#dpl:category=MyCat|noresultsfooter=0|resultsheader=%PAGES%|mode=userformat}}.

The category contains more than 500 members, so I set $wgDplSettings['allowUnlimitedResults']=true; in LocalSettings, but I only got 500 again.

Setting $wgDplSettings['maxResultCount']=10000; and $wgDplSettings['allowUnlimitedResults']=false; in LocalSettings... the same 500.

Setting $wgDplSettings['allowUnlimitedResults']=true; in LocalSettings and the parameter "count=" in the #dpl-command above... the same 500.

I got the correct count by editing ParametersData.php the value for 'count' 'default'=500' in a higher value say 10000.

The two DplSettings above left to standard ("false" and "500" respectively). I'm using the latest DPL-version 3.0.9 and MediaWiki 1.25.3.

Can someone please check this. Thanks. Karsten [[Special:Contributions/192.53.103.119|192.53.103.119]] 11:13, 6 April 2016 (UTC)

== How to sort items alphabetically? ==

How do I set the list to sort the results alphabetically? This page and the manual is pretty confusing.

== Conflict b/w Extension:Lockdown and Extension:DynamicPageList3 ==
Hi all,
there seems to be a conflict between [[Extension:Lockdown|Lockdown]] and [[Extension:DynamicPageList3|DPL3]] in cases where you have custom namespaces defined that are locked. In such cases DPL neglects selection of all pages that reside in locked namespaces.
Though in LocalSettings.php
* nothing is set for <code>[[Manual:$wgNonincludableNamespaces|$wgNonincludableNamespaces[]]]</code> thus principally allowing transclusion and
* <code>[[Extension:DynamicPageList3|$wgDplSettings['allowedNamespaces']]]</code> is set to default value null hence allowing all namespaces for DPL.

Example: let ''Secure'' be a custom name space that has been locked down for everyone except sysop. Sysop executes following dpl code:

<source lang="php">
<dpl>
namespace=Secure
lastrevisionbefore="20161231"
ordermethod=lastedit
</dpl>
</source>

This renders message: ''Extension:DynamicPageList (DPL), version 3.0.7: Warning: No results.'' though ''Secure'' has several pages.

Any ideas?

== Switching from previous version ==

The wiki [http://www.mobadaten.info/wiki/Spezial:Version MoBaDaten.Info] ist still runing with the [[Extension:DynamicPageList (third-party)|''DynamicPageList (third-party) extension'']]. The introducing note of the [[Extension:DynamicPageList3|''DynamicPageList3 extension'']] promises fully backwards compatibility. If I want to switch from that “ancient” version to this revised version, I only have to do the following steps:
# Upload of the ''DynamicPageList3 extension'' into the extension folder
# Change of the require_once statement in LocalSettings.php (wiki is still running with Mediawiki 1.23)
# {{ {{TNTN|Done}} }} without any unpleasent surprises afterwards …???

== List is not going to update? ==

I installed DPL3 for lastedit list in main page. But I got a problem that list will not refresh by itself.

The list content will keep as no change since I edited it. Refresh, logout, close window is not going to change anything.

Anytime I edit the settings in LocalSettings.php or edit the code, then list will update. Any possible reason?

Here's my code:
<pre><DPL>
category = ABC
addeditdate = true
ordermethod = lastedit
order = descending
count = 10
</DPL></pre>

Additional question:

1. When I set namespace = 0, which should display content from main space. But I got this error:

Extension:DynamicPageList (DPL), version 3.0.9: 警告: 錯誤的 '$0' 參數: 'namespace'! 正在使用預設值: '0'。說明: $0= $3。

2. When I tried to use firstedit as ordermethod, the result is totally the same with lastedit. Is it a bug? How to fix it?

Thanks for reply! --[[User:Harry0725|JHK]] ([[User talk:Harry0725|talk]]) 02:09, 18 August 2016 (UTC)

== "shownav" style ("next 100") navigation bar for list generated by DPL ==

I would like to use DPL to generate a list of recently changed pages.
List can run into 100s of entries.
I would like to put a navigation bar like the one that is automatically generated by Special:NewPages.
Generate links like (Newest) (Newer 100) (Older 100) (Oldest).
Clicking on these links, DPL should generate a list of relevant set of pages.
Can this be done?
Can you show me how?
Size of list is not predetermined.

== How do you exclude lastedits when the edit was done by bot? ==

We have a DPL query which shows the date/time of the last edit on all our Talk pages, a link of the person who last edited the talk page, a link to the corresponding main page and the value of the (SMW) property Editor on the corresponding main page.
We recently had bot activity (from [[extension:MassEditRegex]]) that made updates to the talk pages and now all these last edits from bot are listed. So I want to 'not see' any edits from bot, similar to hiding updates from bot on Recent Changes. I was looking at something like using <code>notmodifiedby=bot</code>, but that doesn't give the desired result. Any ideas?

This is the query:
<pre>
{{#dpl:
|namespace=Talk
|ordermethod=lastedit
|order=descending
|addeditdate=true
|adduser=true
|format=¶{¦ class="wikitable sortable"

== DPL: "**" will add all DIRECT subcategories of that category DB ERROR ==

When adding the asterisk to a category in the DPL parser function to add search in subcategories I always get an error:

A database query error has occurred. This may indicate a bug in the software.
Fatal exception of type "Wikimedia\Rdbms\DBQueryError"

The code can be as simple as :
<noinclude>
{{#dpl:
category= **<nowiki>{{PAGENAME}}</nowiki>
}}
</noinclude>

Any hint of why this might be and how to solve it?
Or how to search in subcategories of the current one?

Thanks,

== Gallery tag stops the processing of Format special symbols ==

The example in the documentation:

{{#dpl:

|namespace = Image

|format = <nowiki><gallery></nowiki>,%PAGE%\n,,<nowiki></gallery></nowiki>

}}

DOES NOT work and it just produces a Gallery with ONE "photo" reading ,%PAGE%\n,, like in:
<gallery>,%PAGE%\n,,</gallery>

Whereas:

{{#dpl:

|namespace = Image

|format = <nowiki><gallery></nowiki>

File:Gorrion.jpeg

File:Passer-montanus.jpg

File:Milano.jpeg

<nowiki></gallery></nowiki>
}}

DOES work producing a Gallery with three photos.

In the test I have done, it seems that as soon as DPL encounters the <gallery> tag it stops processing as symbols the following characters so there is no way to pass to the Gallery the resulting list of pages.

As it is in the documentation... did it ever work in previous versions?

Any workaround available for this great functionality?

YES: The workaround is as simple as using the Escape characters of DPL. The following code works:

{{#dpl:

|namespace = Image

|format = «gallery»,%PAGE%\n,,«/gallery»

}}

I have corrected the mistake in the documentation.

== runtime error with MW 1.29 (Cite extension conflict) ==

The code in DPL.php near line 80 tries to access private variables from the Cite extension to avoid that citations get lost that were made before DPL is called. The php interpreter does not allow such kind of access and you will get an error message which blocks the whole wiki installation.
As a quick work around you can disable the workaround. In the long run the conflict should be solved via API calls to Cite.php (if this is possible).

== original documentation is available again ==

I (Algorithmix aka Gero) am the author of the original manual (and of large code portions of DPL). Unfortunately the website with the manual was down for some time due to a PHP version change. I migrated the manual to another server (the old link to http://semeb.com/dpldemo still works) and upgraded the MW version to a more recent one.

User accounts that were valid for the original website should still work.

I noticed that there is a (partial) copy of the manual at "gamepedia". In case the version at gamepedia contains some updates/corrections: How should we proceed?

:{{note}} ''This is a continuation and fork of [[Extension:DynamicPageList (third-party)|DynamicPageList (third-party)]]. It is a fully reworked object oriented code base, significant code and database speed improvements, and is fully backwards compatible with previous versions.''

The '''DynamicPageList3''' extension is a reporting tool for MediaWiki, listing category members and intersections with various formats and details. For full documentation, see the [http://followthescore.org/dpldemo/index.php?title=Extension_DPL full original manual] or the [http://help.gamepedia.com/DPL:Manual manual at gamepedia].

When invoked with a basic set of selection parameters DPL displays a list of pages in one or more categories. Selections may also be based on factors such as author, namespace, date, name pattern, usage of templates, or references to other articles. Output takes a variety of forms, some of which incorporate elements of selected articles.

This extension is invoked with the parser function <code>{{#dpl: .... }}</code> or parser tag <code><DPL></code>. A [[Extension:DynamicPageList (Wikimedia)|Wikimedia]]-compatible implementation of certain features can be invoked with <code><DynamicPageList></code>.

Complex look ups can result in computationally expensive database queries. However, by default all output is cached for a period of one hour to reduce the need to rerun the query every page load. The [http://help.gamepedia.com/DPL:Parameters:_Other_Parameters#cacheperiod DPL:Parameters: Other Parameters] manual page contains information on parameters that can be used to disable the cache and allow instant updates.

== Configuration ==
These are DPL's configuration settings and along with their default values. To change them make sure they are defined before including the extension on the wiki. More configuration information is available on the '''[http://help.gamepedia.com/DPL:Source_and_Installation#Configuration Source and Installation]''' manual page.

'''Note:''' In release 3.0.4 the configuration variable name was changed from <code>$dplSettings</code> to <code>$wgDplSettings</code>. This was to faciliate compatibility with Mediawiki 1.25's extension registration change.

{|class = "wikitable"
!Setting
!Default
!Description
|-
|<code>$wgDplSettings['allowedNamespaces'] || <code>null</code> || By default all existing namespaces are used when DPL initializes. Customize this setting with an array of namespace constants to restrict DPL to work only in those namespaces.
|-
|<code>$wgDplSettings['allowUnlimitedCategories']</code> || <code>false</code> || Set this to true to ignore 'maxCategoryCount' and allow unlimited categories. Please note that large amounts of categories in a query can slow down or crash servers.
|-
|<code>$wgDplSettings['allowUnlimitedResults']</code> || <code>false</code> || Set this to true to ignore 'maxResultCount' and allow unlimited results. Please note that large result sets may result in slow or failed page loads.
|-
|<code>$wgDplSettings['behavingLikeIntersection']</code> || <code>false</code> || Set DPL to always behave like Extension:Intersection.
|-
|<code>$wgDplSettings['categoryStyleListCutoff']</code> || 6 || Maximum number of items in a category list before being cut off.
|-
|<code>$wgDplSettings['fixedCategories']</code> || empty array || This does something with preventing DPL from "looking" at these categories.
|-
|<code>$wgDplSettings['functionalRichness']</code> || 3, 0 if $dplMigrationTesting is set to true || Set the level of parameters available to end users.
|-
|<code>$wgDplSettings['maxCategoryCount']</code> || 4 || Maximum number of categories to allow in queries.
|-
|<code>$wgDplSettings['minCategoryCount']</code> || 0 || Minimum number of categories to allow in queries.
|-
|<code>$wgDplSettings['maxResultCount']</code> || 500 || Maximum number of results to return from a query.
|-
|<code>$wgDplSettings['recursiveTagParse']</code> || <code>false</code> || Do recursive tag parsing on <nowiki><dpl></nowiki> parser tags converting tags and functions such as magic words like <nowiki>{{PAGENAME}}</nowiki>. This is similar to the <nowiki>{{#dpl}}</nowiki> parser function call, but may not work exactly the same in all cases.
|-
|<code>$wgDplSettings['runFromProtectedPagesOnly']</code> || <code>false</code> || Set this to true to allow DPL to run from protected pages only. This is recommend if wiki administrators are having issues with malicious users creating computationally intensive queries.
|-
|<code>$wgDplSettings['handleSectionTag']</code> || <code>false</code> || Set this to true to have DPL handle <nowiki><section></nowiki> tags outside of DPL parser tags.
|}

The global variable {{manual|$wgNonincludableNamespaces}} is automatically respected by DPL. It will prevent the contents of the listed namespaces from appearing in DPL's output.

'''Note: <code>$wgDplSettings['maxResultCount']</code> is a LIMIT ''on the SQL query itself''. Some DPL query parameters like <code>includematch</code> are applied ''after'' the SQL query, however, so results here may easily be misleading.'''

=== Functional Richness ===

DynamicPageList has many features which are unlocked based on the maximum functional richness level. There are some that can cause high CPU or database load and should be used sparingly.

* <code>$wgDplSettings['functionalRichness'] = 0</code> is equivalent to Wikimedia's [[Extension:DynamicPageList (Wikimedia)|Wikimedia]]
* <code>$wgDplSettings['functionalRichness'] = 1</code> adds additional formatting parameters
* <code>$wgDplSettings['functionalRichness'] = 2</code> adds performance equivalent features for templates and pagelinks
* <code>$wgDplSettings['functionalRichness'] = 3</code> allows more-expensive page inclusion features and regular expression queries.
* <code>$wgDplSettings['functionalRichness'] = 4</code> permits exotic and potentially dangerous batch update and delete operations; not recommended for public websites. Includes debugging parameters for testing and development.

== Usage ==
===Extended DPL Functionality===
Extended DPL is invoked by using the parser function <code>{{#dpl: .... }}</code>, or the parser extension tag <code><DPL> .... </DPL></code>.

:''See: [http://help.gamepedia.com/DPL:General_Usage_and_Invocation_Syntax Manual - '''General Usage and Invocation Syntax'''] and [http://help.gamepedia.com/DPL:Parameters:_Criteria_for_Page_Selection DPL:Parameters: '''Criteria for Page Selection''']''

=== Backwards Compatibility ===
Functionality compatible with Wikimedia's DPL extension can be invoked with <code><DynamicPageList> .... </DynamicPageList></code>. Further information can be found on the [http://help.gamepedia.com/DPL:Compatibility Compatibility manual page].

==Usage Philosophy and Overview==
With the assumption there are some articles written about ''countries'' those articles will typically have three things in common:
* They will belong to a common category
* They will have a similar chapter structure, i.e. they will contain paragraphs named 'Religion' or 'History'
* They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

===Generate a Report Based on '''countries'''===
If there was a need to assemble a report of what countries practice a certain religion this could be easily done with the '''category''' and '''linksto''' parameters.
<pre><nowiki>
{{#dpl:
category=countries
|linksto=Pastafarianism
}}
</nowiki></pre>

With DPL one could:
* Generate a list of all those articles (or a random sample)
* Show metadata of the articles (popularity, date of last update, ..)
* Show one or more chapters of the articles ('transclude' content)
* Show parameter values which are passed to the common template
* Order articles appropriately
* Present the result in a sortable table (e.g.)
* Generate multiple column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* Select by a logical combination (AND,OR,NOT) of categories
* Specify a range for the number of categories the article must be assigned to
* Select by a logical combination (AND,OR,NOT) of namespaces
* Define a pattern which must match the article's name
* Name a page to which the article must or must not link
* Name a template which the article must or must not use
* Name a text pattern which must occur within external links from a page
* Exclude or include redirections
* Restrict your search to stable pages or quality pages ("flagged revisions")
* Use other criteria for selection like author, date of last change etc.
* Define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* Article Name
* Article Size
* Date of last change
* Last User to Make an Edit

'''Define attributes you want to see'''
* Article Name
* Article Namespace
* Article Size
* Date of Last Change
* Date of Last Access
* Last User to Make an Edit

'''Define contents you want to show'''
* Whole Article
* Contents of Certain Sections (Identified by headings)
* Text Portions (Defined by special marker tags in the article)
* Values of template calls
* Use a custom template to show output

'''Define the output format'''
* Specify header and footer for the default output
* Use ordered list, unordered list
* Use tables
* Format table fields individually by applying templates to their content
* Use category style listing
* Truncate title or contents to a certain maximum length
* Add a link to the article or to one or more of its sections

==Considerations==
===Performance===
DPL's code execution and database access is typically fast for typical category and article look ups. However, using loose LIKE and REGEXP match parameters and/or requesting large data sets can result in long database access times. Parser time should also be kept in consideration. For example, having the query of image results go into a template that displays them will result in a parser media transform for each one. This can quickly eat up 2MBs of RAM per media transform.

==See Also==
===Further Reading===
DPL can do much more than we can explain here. A complete '''[http://help.gamepedia.com/DPL:Manual manual]''' is available with full parameter documentation.

Algorithmix: /* Code restructuring of DPL */ new section

== Short URL Pages ==
Alexia, MediaWiki handles routing of paths to pages internally using REQUEST_URI. Including a ?title=$1 inside of a rewrite overrides MediaWiki's internal correct handling of urls. And in the case of webservers with broken query escaping code like Apache can result in titles such as those including pluses and ampersands breaking. But either way it's incorrect when path routing in core is getting more complex and moving towards internal support for 404 handling, routing different types of url patterns, etc...

All the old short url guides were written without a complete knowledge of rewrites and how MediaWiki handles urls. With the same mistakes being repeated over and over. The large collection of guides is also very unfriendly towards users trying to get short urls working. New manual pages with the proper ways to setup short URLs are being written to replace all the old guides, with notes on all the edge cases included. And that knowledge is being put into a tool to generate full short URL configs based on various bits of information. The plan is to build up enough canonical information about short URL configuration for a future version of MediaWiki to have short URL configuration handling built into the installer so everyone can easily have it.

Btw, the Nginx manuals explicitly state not to use if() to test for file existence: http://wiki.nginx.org/Pitfalls#Check_IF_File_Exists [[User:Dantman|Daniel Friesen (Dantman)]] ([[User talk:Dantman|talk]]) 04:14, 4 April 2013 (UTC)

: I have a complete knowledge of how Mediawiki handles URLs and did when that NGINX configuration was created. It does not break URL handling and issues with special characters are non-existent. For NGINX I could change the redirect to "rewrite ^/([^?]*)? /index.php/$1". That should work the same, but I have not personally tested it. This short URL setup has also been tested on Apache on Linux for the same issues.
: Using NGINX's if directive is fine. "Using if to ensure a file exists is horrible. It's mean." It just says it is horrible, but with no quantifiable reason. "Just Because" is not a real reason. The if directive simply gives more flexibility for file handling. You could have linked to [http://wiki.nginx.org/IfIsEvil] instead, but that just also says using rewrites inside an if directive inside a location is fine for now. The current configuration shown does work and more importantly does work with version of NGINX before 0.7.27.(Those people really should upgrade though due to security flaws.) The internal NGINX configuration in use at Gamepedia is newer, does use try_files in cases where it makes sense, but does breaks backwards compatibility. The base NGINX configuration provided in the manual page should get anyone started to setting their wiki up on NGINX and still give them flexibility for tailoring it to their environment.

::Not rewrite /index.php/$1. The /$1 is as unneeded as ?title=$1. You just want to send the request to index.php. You actually don't need nginx's rewrite engine at all. Unless you're trying to support the 404 thumb handler. Although in the future you won't need it for that either.
::You can actually get short URLs working in /wiki with something as simple as this:
<pre>
location /wiki {
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root/index.php;
fastcgi_pass 127.0.0.1:9000;
}
</pre>
::And root urls can also be done by simply making that a @wiki and using try_files.
::I've never seen a person with a version of nginx before 0.7.27. In fact other php projects like Drupal have already dropped support for nginx before that version and started using try_files. [[User:Dantman|Daniel Friesen (Dantman)]] ([[User talk:Dantman|talk]]) 06:06, 4 April 2013 (UTC)

== PDFEmebed ==

I'm having a terrible time trying to get it to work. If I explicitly state a file name, it works great. But if I try to pass in the file name with a template, I get "The URL or file path given to embed a PDF is blank."

Is it something with the extension or some obscure feature of templates?

The template is along the lines of this:

<code><pdf width="{{{width|500}}}" height="{{{height|800}}}">{{{file}}}</pdf></code>

I've checked the value of the parameter "file" in various ways and it is passed. But not within <pdf>. Any help is appreciated

== Code restructuring of DPL ==

Hi Alexia,

I was really happy to see that you are making efforts to improve the maintainability of DPL ("third party extension").
Some years ago I inherited the DPL source code and then gradually added more and more functions - but, sad to say,
I never found the energy to improve its structure. A lot of my energy also went into the manual and supporting users.

Looking back, I wish I had thrown away the initial version and started from scratch. But I was always interested to
use DPL ad hoc as it was in various projects and time was so scarce.

I would be glad if you came up with an improved version so that the code can have some more years of life expectancy.
I still feel it is a useful extension and can do a lot of things which help to make wiki contents transparent.

Good luck, Gero [[User:Algorithmix|Algorithmix]] ([[User talk:Algorithmix|talk]]) 14:13, 14 October 2014 (UTC)

:You can use phantom templates for that purpose.

And within the phantom template you can do whatever you like - which means that you can simply output the third parameter.

== Tweak to make DPL backward compatible with DynamicPageList2 <suppresserrors> parameter ==

I'm one of the admins at ChoralWiki (www.cpdl.org), a free Public Domain scores library, and we use [[Extension:DynamicPageList2|DynamicPageList2]] a lot in it with parameter <suppresserrors> set to 'true'. We were doing an upgrade test to the newest version of DynamicPageList and after the upgrade all our DPL queries started showing this warning:

%DPL-1.7.4-WARNING: Unknown parameter '$0' is ignored. Help: available parameters: suppresserrors.

After a quick research we realized that parameter <suppresserrors> is no longer supported by the new DPL versions. It would be a pain to edit all pages where it appears, so we decided to tweak the DPL code to recognize it and behave as expected. We made the changes below, tested it and it worked fine. So we decided to post it here in case someone else faces the same problem. All one needs to do is to add the following lines in red to file ''DinamicPageList2.php'':

line 682:

/**
* noresultsheader / footer is some wiki text which will be output (instead of a warning message)
* if the result set is empty; setting 'noresultsheader' to something like ' ' will suppress
* the warning about empty result set.

== Index (List of index-terms) for a book ==
I am experienced in editing wikipedia-articles. Now I want to use mediawiki on my server to write a book (around 1.000 articles). I want to mark index-terms in articles and have one page with a sorted index.
The book will exist of 1.000 articles. So it is no problem to generate the article dynamicaly when I will open the index.
Is DPL the right extension to do the job?

How to mark the index-terms in articles?
Which <dpl></dpl> -code do I need?

Or is there a better solution than DPL?
Regards, jan--[[Special:Contributions/89.52.155.34|89.52.155.34]] 23:55, 13 January 2009 (UTC)

I made a beginning:

I have a template '''template:Index''' and call it in articles with with
<pre>
{{Index|keyword}}
</pre>

For the output of the whole Index I have an article with:
<pre>
<dpl>
uses=Vorlage:Index
include={Index}:1
table=,articletitle,keyword
</dpl>
</pre>
It works!

How can I get an output in an alphabeticle order like this?
<pre>
keyword-1
..... articletitle 1
..... articletitle 2
..... articletitle 3
..... articletitle ...

keyword-2
..... articletitle 4
..... articletitle 5
..... articletitle 6

::Hello Jan, creating a permuted index is a challenge because DPL normally walks sequentially through all articles which match the selection criteria and collects the desired information (in your case template invocations). In your case one would have to store the collected data (using the ''arrays'' extension ), re-arrange the order and then produce the output in a final step. With less than 10 lines of code all this is possible:
::<center>see     ''' http://semeb.com/dpldemo/index.php?title=DPL_Example_017 ''' </center>
::I know SMW and think it is powerful for expert users. The idea of DPL is to use MW as it is without introducing new syntax for those users who ''write'' articles.

== Problems ==

Hi. I have a problem with labeled section transclusion, the ''section'' tags show up along with the transcluded text. This problem only showed up recently; the page was doing fine four months ago when I left it. When I came back a few days ago, no changes have been made to the articles but the DPL pages have broken formatting. It is a Wikia page and I asked the Wikia staff about it too, but they haven't recognized something from their end being the source of the problem either. So here's the problem. Instead of this:

http://img.photobucket.com/albums/v59/daarklord/ForumGraphics/DplWtf01.gif

I get this instead:

http://img.photobucket.com/albums/v59/daarklord/ForumGraphics/DplWtf00.gif

My wiki can be found [http://nilgiri.wikia.com/wiki/Nilgiri_Wiki here].
The formatting error can be seen [http://nilgiri.wikia.com/wiki/Neck_equipment(all) here].

Please help. Thank you.

I installed the extension on a private wiki according to the notes on the page (#include("$IP/extensions/intersection/DynamicPageList.php");), but it doesn't work. When I disable (commtenting out) the extension in the localsettings.php, I can see the page. If I enable the extension I only get a white page displayed on pages with <DynamicPageList></DynamicPageList>, all other pages can be edited and shown.

==A Bug?==
I use DPL together with MediaWiki 1.14.0, SMW 1.4.2, DPL 1.7.9 If I follow a link, that is done by the Call-Extension, the CSS-File of SMW is not included. What can I do? The main problem: The field “smwsortkey” is not more hidden, because the style for it is not included. Christian Weiss 14:44, 27 May 2009 (GMT+2)

:Please give more details. I assume that the problem has nothing to do with DPL; this means that it also occurs if you use the Extension:Call from the browser's URL-line or within a normal document like this <nowiki>[[Special:Call/:Mypage,a=b]]</nowiki>. I don´t understand your remark about a "style". Are you talking about css? Can you reproduce the error on the [http://semeb.com/dpldemo dpldemo website]? It has DPL 1.7.9 and SMW 1.0 installed.

:::It's like you said: I call a Template by the Call-Extension, the DPL-Calendar ":Current events" for example. If it's included the normal Way in a Page, in the HTML-Source the "SMW_custom.css" and the "SMW_sorttable.js" are included. If the Template ist called by the "Call"-Extension those files are not included in the HTML-Source. A workaround ist to include those files in the Common.css and Common.js for Skins, so it is included everytime. For the SMW_sortable.js I get then 2x sortbuttons :-) I think, the Call-Extension ist part of your Pakage, so I write my Problem to you. Christian Weiss 10:06, 06 Jun 2009 (GMT+2)

== LoF ==

I sthe LoF ment to be set as global in LocalSettings? I'd prefer it as option per DPL call. So I want to use a complex DPL call I would set LoF = 3 or sth inside the call. But if I want to run a very simple call I would set LoF = 0 to save some ressources. --[[User:Subfader|Subfader]] 15:15, 17 June 2009 (UTC)

== DPL Doesn't Work after MW Upgrade from 1.13 to 1.15.1 ==

Hi, I have a private wiki we use as a content Management system at work. I updated the wiki from MW.1.13 to MW.1.15.1, and suddenly DPL doesn't work. For example, I have a page for each of our main applications, with a supbage called 'Troubleshooting'. Below that are more subpages, one for each troubleshooting document. The '/Troubleshooting' subpage consists entirely of DPL to list the child subpages for a user to browse and jump to.

For example (changing the page names to protect proprietary information):

We have a set of pages like so:

* Main:Zazaza
* Main:Zazaza/Troubleshooting
* Main:Zazaza/Troubleshooting/Error 51 - File not Found
* Main:Zazaza/Troubleshooting/Can't Save Configurations
* Main:Zazaza/Troubleshooting/App Crashes if User Chews Bubble Gum

The top page, Main:Zazaza, describes the application and has a link to Main:Zazaza/Troubleshooting.

Main:Zazaza/Troubleshooting consists entirely of DPL code that will list the three 'troubleshooting' child subpages with links. This page's DPL Code is as follows:


<DPL> 
titlematch=Zazaza/Troubleshooting/% 
notnamespace=Image 
notnamespace=Image_talk 
notnamespace=Template 
notnamespace=Template_talk 
replaceintitle=/.......Troubleshooting./, 
</DPL>


Previously, the DPL worked, and a user browsing to the Zazaza/Troubleshooting page would see a list of clickable links:

Error 51 - File not Found
Can't Save Configurations
App Crashes if User Chews Bubble Gum

Now, since the 1.15.1 upgrade, all that shows up is the following:

Extension:DynamicPageList (DPL), version 1.8.6 : <dpl_log_1>

Before you ask, no, there is no log being generated or updated anywhere within my wiki home that provides me with a clue as to why DPL isn't working.

I confess to being confused because when I originally downloaded DPL in May or June 2008, this was during the time frame that "old DPL" was known as "Intersection" and 'this' DPL was just known as "DPL", and at the time there wasn't even a reference to the forked versions on the extension page. (I only came to learn all of this with my research this past week.) However, I have verified that I am using semeb.com's Dynamic Page List (was using v.1.6.9, now using v.1.8.6.) I downloaded v.1.8.6 earlier in the week from http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/DynamicPageList/, and I just re-obtained the files from the ZIP archive available at http://semeb.com/dpldemo/images/f/fe/Semeb_extensions.zip and redeployed them to be certain. The behavior is still the same as above.

Any help would be appreciated.

== Parsing Pipes ==

I have run into a little bit of a quandary which I am trying to solve. I am trying to create a template with a set of parameters that are passed from a dynamically created list from DPL. However, when using the pipe character in the formatting for DPL like this:
<pre>{{Hot_issues
|<DPL>category=Application
category=Hot_issues
format=,|,[[%TITLE%]],
notnamespace=Category
noresultsheader=Nothing found...</DPL>}}
</pre>
...the pipe character is not parsed by the templating system, I think because of the order in which things are processed... The result is all the articles listed like this: "|Article1|Article2", and so on, instead of passing each one as a template parameter. I have been trying, but I can't think of a way around this. Does anybody have any thoughts on this? --[[User:Bsmithme|Bsmithme]] 21:12, 18 July 2009 (UTC)
:I have tried using subst:Hot_issues but that had no effect. I've also tried creating a template with "|", but that didn't work either. I think I am approaching it wrong...--[[User:Bsmithme|Bsmithme]] 21:15, 18 July 2009 (UTC)

:::::Think the best way to illustrate what I'm trying to do is this:

== RESOLVED: Fatal error ==

After upgrading my wiki to MW 1.15 I got the error message:
<pre>Fatal error: Unsupported operand types in /home/schlott/public_html/wiki/includes/parser/LinkHolderArray.php on line 33</pre>
and the extension stoped working.

The solution was inside the DynamicPageList/DPL.php with the following statement in Line 36:
<pre>
// cloning the parser in the following statement leads in some cases to a php error in MW 1.15
// You must apply the following patch to avoid this:
// add in LinkHoldersArray.php at the beginning of function 'merge' the following code lines:
// if (!isset($this->interwikis)) {
// $this->internals = array();
// $this->interwikis = array();
// $this->size = 0;
// $this->parent = $other->parent;
// }
</pre>

After adding the mentioned code lines to LinkHoldersArray.php the extension works just fine. -- Flaming Moe

== Comment on differing versions by [[User:Algorithmix|Algorithmix]] ==
* Note that the version running on Wikimedia sites was at some point in time renamed to [[Extension:Intersection]] to avoid confusion with the extension described here. But the documentation still was talking of "DynamicPageList" and the SVN path was not renamed.
* Recently 'Intersection' claimed back its ancient name and that is why you now find the documentation of 'Intersection' under 'Extension:DynamicPageList'.
* On the other hand the DPL extension described here was still named 'DynamicPageList' and new functions were added. At some point in time downward compatibility with the version running on Wikimedia sites was lost. The extension was renamed to 'DynamicPageList2' but the documentation was still talking of "DynamicPageList".
* Then another bunch of functionality was added and downward compatibility (with DPL2) was lost. The name of this version was changed back to DPL (which was thought to be 'free').

''All this has created much confusion. Read below for a suggestion on how to re-unite the different variants.''

This extension '''Dynamic Page List (DPL)''' has the same roots as [[Extension:Intersection]]. Until recently DPL was almost - but not exactly - downwards compatible with ''Intersection''. A lot of confusion comes from the fact that ''Intersection'' uses the tag <DynamicPageList> whereas '''Dynamic Page List (DPL)''' uses the tag <DPL>.

DPL offers functionality '''that goes far beyond''' ''Intersection''. Some of this functionality might be useful also on Wikimedia sites. But the problem is that inexperienced users or people with 'not-so-good-intentions' might write DPL statements which create significant database load.

A good solution - which also puts an end to all naming ambiguities of ''DynamicPageList, DPL, DPL2'' and ''Intersection'' looks like this:
# There should be only ONE extension.
# It should be called ''DynamicPageList'' (short name DPL).
# It should listen to the tags ''DynamicPageList'' and ''DPL'' for compatibility reasons.
# Its sources should be in the mediawiki SVN
# It should be strictly downward compatible with ''Intersection''.
# It should offer a configuration switch (let us call it LevelOfFunctionality = LoF) which lets the administrator of a wiki decide, how much functionality will be offered to the users:
#* LoF = 0 is exactly identical with ''Intersection'' as of today.
#* LoF = 1 offers additional features which do not affect performance (mainly related to output formatting)
#* LoF = 2 offers additional features which are on the same conceptual level as ''Intersection'' like selection of pages by use of templates or by pagelinks. As the underlying table structures in the mediawiki database design are very similar to categories the performance cost of theses features are comparable in magnitude with ''Intersection'''s current features
#* LoF = 3 offers additional features which are more cost-intensive, like e.g. content transclusion from pages that occur in the DPL result; we think that a dedicated DPL cache could allow to offer these features also on high traffic sites - but this still has to be proved
#* LoF = 4 offers a last group of features which are a somewhat exotic and could create trouble if used by ignorant people (batch updates and batch deletions based on DPL query results)

:My own thoughts on this: it's a good idea, but performance is a huge consideration. I suggest investigating ways to avoid loading DPL code unless it is required, particularly [[Manual:$wgAutoloadClasses|$wgAutoloadClasses]]. Right now APC shows that it is touching all the code on every page access, and that's a significant cost when you have a large number of pages being accessed.

== Trying to List Pages... ==
Trying to List Pages within a Namespace in Category Mode, Alphabatized on a non category page. Sounds ridiculous however this is the syntax that i am using:
<pre><dpl>
namespace=Article
shownamespace=false
mode=category
ordermethod=category,title
</dpl></pre>
What i am trying to do is show all pages in the article namespace on a page in category mode alphabetized by the page title rather then the namespace. Currently all pages are organized under "A" because the pages are named Article:Page Name. I want to eliminate or mask the Article so that they are organized by Page Name.

:Hmh, you aren't very clear.
:1) is there really a custom namespace called "Article"? Cos otherwise you mean Main: "namespace="
:But I guess I know what you mean. Like in [http://semeb.com/dpldemo/index.php?title=User:Subfader/Olli1/O7 this example] you don't want U headings but 0-Z... I dunno a solution :/ --[[User:Subfader|Subfader]] 21:17, 21 October 2009 (UTC)

===Workaround ===
If you apply a very small patch you can use
ordermethod=titlewithoutnamespace
to get the desired result:

find (near line 1860 in DPLMain.php in the latest version)
case 'titlewithoutnamespace':
and add the following line immediately after that line:
$sSqlSortkey = ", $sPageTable.page_title ".$sOrderCollation." as sortkey";

I will add this code line to the next release.
In fact, the patch will make the new behaviour the default (which is o.k., I think). Use <tt>ordermethod=title</tt> to switch to the old behaviour.

==DISPLAYTITLE and DYNAMIC PAGE LIST==
is it possible to tie this to DISPLAYTITLE to sort pages by their DisplayTitle?

==installation instruction problems==
Thanks for this powerful extension. In order to help others to use it, I want to report two problems I just had in following the installation instructions in the article.

The instructions say:
add include("$IP/extensions/DynamicPageList/DynamicPageList.php"); to LocalSettings.php
However, the actual file downloaded for v1.14 was named DynamicPageList2.php. This modification worked:
include("$IP/extensions/DynamicPageList/DynamicPageList2.php");

The second problem is probably due to my lack of familiarity with PHP. The instructions appear to say to add a function call in LocalSettings after the include() statement above to control the richness level, like this:
ExtDynamicPageList::setFunctionalRichness(3);
However, this caused a fatal error, so I commented it out. Should the call be like this?
DynamicPageList2::setFunctionalRichness(3);

== Having DPL Maintain #section Links ==

If the pages I'm building my DPL from have links like <tt><nowiki>[[#section|A Section]]</nowiki></tt>, is it possible to to have DPL maintain the url of the page with that specific section, rather than have it change it to the page that has the DPL on it? — [[User:Cosmotron|Cosmotron]] 18:56, 8 November 2009 (UTC)

== Template:DPL_Extension creation as potential redirect loop ==

There is a DPLSetup.php routine, commonSetup(), which attempts to create an <nowiki>{{Extension DPL}}</nowiki> template using the userid of the first user to visit the wiki after the extension is installed:

<source lang="php">
private static function commonSetup() {

if (!isset(self::$createdLinks)) {
self::$createdLinks=array(
'resetLinks'=> false, 'resetTemplates' => false,
'resetCategories' => false, 'resetImages' => false, 'resetdone' => false , 'elimdone' => false );
}

// make sure page "Template:Extension DPL" exists
$title = Title::newFromText('Template:Extension DPL');
global $wgUser;
if (!$title->exists() && $wgUser->isAllowed('edit')) {
$article = new Article($title);
$article->doEdit( "<noinclude>This page was automatically created. It serves as an anchor page for ".
"all '''[[Special:WhatLinksHere/Template:Extension_DPL|invocations]]''' ".
"of [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)].</noinclude>",
$title, EDIT_NEW | EDIT_FORCE_BOT );
die(header('Location: '.Title::newFromText('Template:Extension DPL')->getFullURL()));
}

}
</source>

Two issues with this:
* (minor) The external link [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)] points to a disambiguation page here instead of to the actual extension info.
* (not so minor) If creation of the template fails, the user is redirected to [[Template:Extension DPL]] regardless, and the failed attempt to create the template is repeated until the browser detects this as a redirect loop and shuts down.

I've noticed that new installs, if started with just a blank set of database tables and a LocalSettings file (without running the MediaWiki installer again for the new wiki), are prone to go into an endless HTML redirect loop because of this code. Attempts to run maintenance/update.php from the command line may also abruptly end with errors if the extension is trying to create this page during the "update.php" run and the database is not yet updated to the latest MW format (and therefore not ready for the template creation attempt).

There needs to be some error handling; if the creation of the placeholder template fails, don't just keep trying forever - at least not if this is going to return errors or redirect loops. --[[User:Carlb|Carlb]] 14:12, 9 November 2009 (UTC)

== [SOLVED] White page after including Semantic Media Wiki Extension in LocalSettings.php ==

Hello,
I installed the Semantic Media Wiki extension on a Media Wiki 1.16.0
According to the install notes on the page I appended the following two lines to the LocalSettings.php:
 
include_once("$IP/extensions/SemanticMediaWiki/SemanticMediaWiki.php"); 
enableSemantics('filerepos.de'); 
 
After that I get a blank page on every URL of the Wiki.
Set error_reporting to E_ALL (in LocalSettings.php, SMW-Config-Files) but also got a blank page.

Also tried the hint from the Semantic Wiki Site with no success:

ini_set( 'memory_limit', '100M' );

When I comment the both lines out everything works again.

(Setup: Mediawiki 1.16.0, PHP Version 5.2.6, MySql 5.0.45, Semantic Media Wiki Extension 1.5.3 stable)

Would apreciate any hint.
:This page is only for support for the DynamicPageList extension. You're more likely to get a response if you ask the SMW people. With that said, Did you add the:
error_reporting(E_ALL);
ini_set("display_errors", 1);
as the very first lines of LocalSettings.php (directly below the opening <?php )? If that still doesn't work, try setting error reporting to E_ALL directly in your php.ini file. You can also try checking your webserver's error log as well (doesn't usually have php errors in it, but if its some sort of config problem with your webserver it might have relevant information). [[User:Bawolff|Bawolff]] 22:31, 26 November 2010 (UTC)

 
Thanks for the reply...think ini_set got the errorReporting working.
Now there is some output I can work with:
http://www.mediawiki.org/w/index.php?title=Extension_talk:DynamicPageList_(third-party)&action=edit&section=38
Call to undefined function enableSemantics() in /srv/www/vhosts/filerepos.de/httpdocs/websites/semwiki/LocalSettings.php on line 138

[SOLVED] I accidently downloaded the wiki and the extension with different user...so the wiki wasnt allowed to access the extension.
Changed extension files owner to the same owner as the wiki and so everything works now.
Thanks for the error reporting hint which allowed me to find my mistake

== Undefined index and .default ==

I try to make the DPL-Extension read out a category and get the parameters of a template in the articles of this category. They are meant to be used in another template. I saw another wiki which did it the same way as I did, but I get a strange Error while using the preview on this:

<pre><DPL>
category = Some Category
mode = userformat
includepage = {Template in articles} Kr
allowcachedresults = true
</DPL></pre>

"Notice: Undefined index: tip ... EditPage.php". The line is this: "$tip = $tool['tip'],".
This is strange but probably not that important. The real problem I got ist, that the extension always adds an ".default" at the end of the template. So I get a long list which just says "Template:Template in articles Kr.defaultTemplate:Template in articles Kr.default...".I don't really get the origin of the problem and couldn't find an answer anywhere.
I didn't change anything in the basic code of mediawiki, except for some extra buttons i added in EditPage.php. There are also no extensions, that could affect the DPL extension.--[[User:Eski123|Eski123]] 12:14, 2 January 2010 (UTC)

:My five cents on this: according to [http://semeb.com/dpldemo/index.php?title=Includepage#include_contents_related_to_templates doc], the DPL engine calls a template with the additional sufix ".default" when a page listed in the result does not use the specified template.

== Problems with missing subheads ==

DPL is apparently crashing when used with a subhead that doesn't exist on one of the pages included by Category.

I have the following DPL code on a page called "Current projects":

=Projects in process=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects
|include = #Project steward, #Need
|includetrim=true
|table=class="sortable", Project, Steward, Need
}}

=Completed projects=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects, completed
|include = #Project steward, #Final accounting
|includetrim=true
|table=class="sortable", Project, Steward, Final Accounting
}}

The first DPL call works if I temporarily clip out the second DPL cal, but including the second DPL call displays:

:Fatal error: Call to a member function getPrefixedDBkey() on a non-object in /Library/WebServer/EcoReality/wiki/includes/parser/Preprocessor_DOM.php on line 994

I then looked over the pages in the Category "Projects, completed" and discovered several of them did not have a subhead called "Final accounting." These are old pages, and this worked once upon a time!

For now, I've removed "Final accounting" from the second DPL call, but it seems it should behave better than this in such a case, no? Have I messed up something to cause it to misbehave this way?

See it fixed at: http://www.ecoreality.org/wiki/Current_projects .

== Spaces and underscores ==

It seems that the "titleregexp" parameter doesn't interpret spaces and underscores the same way. In fact, since page names can't have spaces in them, any time there is a space it just flat out fails. This would ordinarily not be such a big deal, so, okay, you learn not to use spaces, however i have a template for detecting direct subpages of a page (but not sub-subpages). the regexp is {{PAGENAME}}/[^/]*$ however, if used on a page with a space in the name, {{PAGENAME}} returns a space there where dpl requires an underscore. It seems to me that spaces and underscores should be totally interchangable in dpl, as they are in the rest of MW. [[User:DeFender1031|DeFender1031]] 11:22, 29 January 2010 (UTC)

:::It doesn't matter where the DPL function comes from, even transcluded from a subpage, it clears the {{tl|reflist}}.

== Great and easy: Searchable Tables ==

I use the TableTools (Firefox-Extension) to search the tables generated with DynamicPageList (Mediawiki-Extension); see here [https://addons.mozilla.org/en-US/firefox/addon/2637]

With the Firefox-Extension installed you can right-click into a table and choose
# show Filter (german: Filter anzeigen)
# show Searchfilter (german: Suchfilter anzeigen)

With the first you get lists where you can choose an item in the table-heading and get all the rows matching this item.

With the second you get searchfields in the heading to use for a wildcard-search.

Both functions are very (!) usefull for the DynamicPageList-tables. But it is not userfriendly for less sophisticated users to right-click to get the function. I would like to put such functionality with an easy dpl-command into the heading, similar to the magicword "wikitable" or "sortable": "searchable". Now I wonder if it would be possible to integrate such a great feature directly into DynamicPageList??

I hope that others are also interested in such a feature.

== Setting parameter without using template? ==

Hi, it seems that all parameters are set in a template. In my wiki, there is a pretty standardized section and i would like to implement DPL on it. It's not a template but just a list of 1....2....3...list. Is there any markup tag that i can tell DPL that item01 = 1.. ; item02 = 2... ; item03 = 3.... ?

The current method is like this. It's actually good but in a FCKeditor-based Wiki, it may be too difficult to ask laymen to learn it.

I seem to have a strange issue after restoring a backup of my wiki on another computer. Both computers are using DPL version 1.8.9.

Basically they just show the function then all of the parameters in what looks like a PRE tag.

The parser tag works fine. I can take the same queries and change them to the tag variant on a test page and they work great.

:I'm not sure what the number of 70760 is, however as far as i know they still play nicely together as long as the version of DPL is post [[rev:68812]]. However with that said, the categorylinks table changed quite a bit in 1.17 (aka current svn head). Some features might break in subtle (or perhaps not so subtle ways) because of that. It will certainly be less efficient for plain ole' category listings (but then again this is a very inefficient extension, so if you care about efficiently, I doubt you'd use it). Short answer: In my testing it still works, but no guarantees (+ the XSS issue). [[User:Bawolff|Bawolff]] 22:10, 13 September 2010 (UTC)

== DPL & Nested Templates? ==

I may be missing something so I am posting the question here. Can DPL query variables passed to a nested template? Meaning, ...
* You have a page named Resource1 which uses a template called ResourceType1 which is a member of the Asset Category.
* Within template ResourceType1 you pass variables to and call the template called AssetInfo.
* You then construct a DPL query which based on the Asset category queries all pages member of Asset and lists the variables found on the nested AssetInfo template

The rational for such a construct would be to list AsseInfo common to all resources which may use different ResourceType templates (type1, type2, etc) but are all members of Asset. Since the include/includepage line in DPL table output must be consistent, querying the nested common template seems the best approach but does not work.
please advise?, thanks ahead of time for replies [[Special:Contributions/208.79.244.111|208.79.244.111]] 23:23, 4 October 2010 (UTC)

== Replace in title breaks with titles that contain parentheses ==

I've just discovered that an article title which contains parentheses causes the replaceintitle statement to break in that it will no longer perform any longer. In context, I have a replaceintitle which is supposed to remove the BASEPAGENAME from the title or an article that is a subpage, so that when I output title I can output only the name of the subpage instead of the entire trail. I still need to do further troubleshooting to see if it is actually BASEPAGENAME or %TITLE% which is breaking. Nevertheless, it's clearly an issue with the extension.

(With that said, I'm not sure how it'd help you with your issue, since the two should be exactly the same with exception of parsing the args before passing to DPL.).

== Use with TreeAndMenu Extension ? ==

Hi,

I only need this:

{{#dpl:category=Foo|format=,**,[[%PAGE%]]\n,}}

..To dynamically add all pages to a tree that is created by the Extension TreeAndMenu.
I´ve tested it and it works great. Though I´m planning an opened wiki I´m a bit scared
about the red box on this extensions main page telling me that it has a major security
risk.

Is it possible to enable this extension only for a specific (admin) page or to eliminate
the security risk by adding some contraints?

Thanks in advance!

Hi again. Sadly that was not the solution. If the option to allow DPL only on protected pages is enabled this also affects the NavTree (Extension: TreeANDMenu) that needs DPL to work propperly. What I need is DPL to only work in the sidebar :-). But I don´t know if that is easily possible?

== Tree and Menu and DPL - Advanced use ==

I'm currently using Tree and Menu and DPL to generate lists as shown in the Example. Works fine.

{{#tree:id=ToolsMenuTree|openlevels=0|root=Tools, Tips and best practice|
* [[Tools and Tricks|Overview]] (Introduction Page)
{{#dpl:category=Tools and Tricks|format=,**,[[%PAGE%]]\n,}}
}}

The problem is that our wiki will have a lot of pages and subpages, making the list expand really fast with similar named entries such as:
Outlook
Outlook/Installation
Outlook/Usage

With the example structure above, is there a way to automatically create subfolders for all subpages using DPL syntax? Should be looking something like that
**Outlook
***Installation
***Usage
Any hints would be greatly appreciated. (Mike)

== Breaks when using ordermethod pagesel ==

I've run into an interesting problem. When attempting to generate a list using "linksfrom" and setting ordermethod to "pagesel", the parser breaks with the following error:
<pre>SELECT DISTINCT `page`.page_namespace as page_namespace,`page`.page_title as page_title,`page`.page_id as page_id, pagesrc.page_title as sel_title, pagesrc.page_namespace as sel_ns, CONCAT(pl.pl_namespace,pl.pl_title) AS sortkey FROM `pagelinks` as plf, `page`as pagesrc, `page` WHERE 1=1 AND `page`.page_is_redirect=0 AND `page`.page_namespace = plf.pl_namespace AND `page`.page_title = plf.pl_title AND pagesrc.page_id=plf.pl_from AND ((plf.pl_from=0)) ORDER BY sortkey ASC LIMIT 0, 500

Error message is:
Unknown column 'pl.pl_namespace' in 'field list' (localhost) </pre>
What's interesting is that this error does NOT occur if I change "linksfrom" to "linksto". What's also interesting is that on a cursory check of DPLMain.php for malformed code and found that the column pl.pl_namespace isn't even referenced in the "linksfrom" section, but is referenced in the "linksto" section, but I may not be looking at it right.

I changed pl.pl_namespace,pl.pl_title to plf.pl_namespace,plf.pl_title - and this ''seems'' to have resolved the issue. [[User:Thorncrag|   Thorncrag  ]] 22:13, 16 March 2011 (UTC)

== Show images of a category including links to pages using these images! ==

Hi all,

I have a difficult question. I would like to create a gallery like that:

{{#dpl:
|category=Oneofmycats
|namespace=Image
|format=«gallery»,%PAGE%¦%NR%. %TITLE%\n,,«/gallery»
}}

That works great. But now I would like to have the name of the page (all of my images are at least only used on one page!) which makes use of the image as image text (not TITLE). In addition to that the name of the page should be a linkt to the page! So it would be possible to show all Images of a certain category including linkt to each page using this image (there is only one page!).

Found this code here:

{{#dpl:
|imageused=myimage.jpg
|format=,[[%PAGE%]]\n,,
}}

But I don´t know how to merge this two operations to one big thing!

Hope you understand what I mean :-).

Thanks in advance.

== DPL for category page – order by second name? ==

I'm using DPL for a personalized category page because I didn't like the MediaWiki-own view. Everything works fine but there is one point I despair of. For the category of persons I want the list to be ordered by second name. In the standard category view this issue is solved by a tag on every page that tells MediaWiki how to order, e.g. on the page "Angie Gielach" <nowiki>[[Kategorie:Personen|Gielach]]</nowiki> to have it listed under "G" instead of "A".

In DPL I use the following code to display the pages of my category "Personen" alphabetically:

<pre><nowiki>
===A===
<DPL>
category = Personen
format = ,\n* [[%PAGE%|%TITLE%]],,
title<=B
</DPL>
</nowiki></pre>

Has anyone a solution for this?

I don't know where else to go for help. I've reviewed bugs and issue pages and really didn't see anything applicable. I even tried to install the Wikimedia version of this extension and that worked fine (although that version doesn't have all the function I want so I'd rather have this one.)

== Variables ==
Is there a conflict between this and [[Extension:Variables]]? In particular, it seemed that DPL was blanking variables, causing an [http://strategywiki.org/w/index.php?title=StrategyWiki:Sandbox&oldid=584025 error message like this], and it was resolved by having the DPL variable declared first before the total variable ([http://strategywiki.org/w/index.php?title=StrategyWiki:Sandbox&diff=584031&oldid=584025 like this]). --[[User:Sigma 7|Sigma 7]] 17:07, 27 September 2011 (UTC)

== Question about "includematch" ==

I use this great extensions in two of mine wikis. In the last times, i have some problems with includematch.
My Wiki is about Final Fantasy XIV Online, for info ;)

NPCs are selling some Items, the item goes in the category:example sells from NPC.
Now, some NPCs sells example-head, examplefeed, example-earring. If i create now the Article examlpe,
i use this DPL:
<pre>
{{#dpl:
|category = {{SUBPAGENAME}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{fixapos|{{fixtick|{{fixparen|{{SUBPAGENAME}}}}}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

Here i use the _Template:Sellsrow to get the Price and the Template:NPC dpl Zones to get all other datas.
In the Template:Sellsrow, i define '''Item'''. Thats why my includematch say get where Item = <nowiki>{{SUBPAGENAME}}</nowiki>.
So, my Articles shows me now in the Table all sellinginformations about:
*example
*example-head
*examplefeed
*example-earring

i try'd some other includematch variations like this:
<pre>
{{#dpl:
|category = {{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

but at least, i have allways the Same problem. It shows me all what that NPC have, where example is in :\
The only what i want to see, is the Data for example >.< Someone knows how i can fix it? [[User:Yukii|Yukii]] 12:52, 17 October 2011 (UTC)

::I'm not quite sure I understood everything you said, so in case you want to clarify, you can tell me in German. // Ich bin mir nicht ganz sicher, dass ich alles richtig verstanden habe, und falls nicht, dann kannst du es gerne auf Deutsch nochmals erklären.
::The problem is, as far as I can see, that you never included the line "Item=..." in your DPL call; you only called to include "Price=..." parameter in the {Sellsrow} template. The includematch function works only, if you include the respective parameter, so in order for it to work, you need to change <code>{Sellsrow}:Price</code> to <code>{Sellsrow}:Item:Price</code>. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 13:43, 22 March 2012 (UTC)

== Warning about $maxResultCount ==

Just as a heads-up, <code>$maxResultCount</code> is '''not''' a limit on DPL's results, but a limit on the amount of rows pulled from the database. '''That is not the same thing'''. For example, the DPL query...

<DPL>
includematch=/\|\stemplate-attribute\s=\svalue/s
titlematch=Foo%
category=Foos
</DPL>

...will '''first pull all pages beginning with "<code>Foo</code>" in the category "<code>Foos</code>" from the database''', and only '''then''' check for the <code>includematch</code> pattern. In other words, if <code>$maxResultCount</code> is 500 and you have 800 <code>Foo%</code> pages in the <code>Foos</code> category, '''''even if just ten of those match your <code>includematch</code> pattern, you will probably not get all ten'''''.

Our solution was to remove the limit entirely (<code>$allowUnlimitedResults = true</code>), because our wiki is private and we have a strong control over authorship.

Your mileage may, of course, vary. -[[User:Pinkgothic|pinkgothic]] 13:32, 30 November 2011 (UTC)

== Null edits (or dummy edits) required for updating DPL listing ==

The wiki I administer makes a huge use of DPLs for constructing lists of pages and controlling workflows--very well might I add.

One problem that I have perennially run into however is the need to execute a null edit in order for pages to properly show up in a DPL when the DPL is grabbing based on, for instance, page category. What I don't understand is that when accessing the page in question the category is correct, but the DPL listing the page will not include the page in its list until executing a null edit on the page. I'm fairly knowledgebale about this extension but I have not come up with a solution to this problem. I've even tried using updaterules to "touch" the page when the list is built, but that feature does not seem to be usable at this point.

Since the page shows the correct category, and the job queue is empty, I can't actually figure out why this is happening. The only thing that I can think of is that the DPL is stored in a cache; however, that should not be causing this since cached results are supposed to be disabled by default. I do have MediaWiki parser cache set to enabled as well as file cache, but disabling these seems to have no effect on the symptom. Any thoughts on this? [[User:Thorncrag|   Thorncrag  ]] 18:40, 12 January 2012 (UTC)

:I may have posted too soon; I ''completely'' disabled caching across the wiki and this seems to have resolved the problem altogether. This works for now, although from a scalability perspective I'm not sure. [[User:Thorncrag|   Thorncrag  ]] 19:20, 12 January 2012 (UTC)

::I think I posted too soon again. I think disabling cache only caused an update, but null edits are still required. I can't seem to find a way around this. [[User:Thorncrag|   Thorncrag  ]] 16:39, 1 February 2012 (UTC)

== "skipthispage" - not bolded when created by DPL ==

Hi! I'm working through the book MediaWiki and Beyond. Great book, but I've run into something that doesn't seem to be working. In the book it says that if you use the 'skipthispage' variable and set it to false, not only will the page you are on show up in your list (in this case a navigation list), but since its pointing to itself, it will default to bolded text rather than a link. I don't seem to be able to get that behavior though. If I put a link to the page within itself, that will bold and present just as text, but not when it comes through the dpl command. Any ideas why? Thanks! [[User:Ncarty97|Ncarty97]] 20:41, 1 February 2012 (UTC)

== DynamicPageList only works with global $wgRawHtml set to true. ==

Between MediaWiki version 1.15 and 1.16 the way the < html > tag is handled changed. As a result, the DynamicPageList extension's abuse of the global $wgRawHtml setting to temporarily enable raw HTML content is broken. The normal way (to my knowledge) for an extension developer to embed raw HTML is to create one or more markers and then to post process the content and replace the markers with HTML after MediaWiki has done all of it's HTML stripping.

:That is correct.

== Attempting to use DPL to create a table "on-the-fly" on any given article page by pulling from a list on a page; Getting error message: %DPL-1.7.6-WARNING: No results! ==
* Hi, so my goal in this scenario is to create a table on-the-fly using DPL and put that table on any given article page (I've opted to do a template call to facilitate this) -- and so part of the problem has been to figure out which of the DPL commands are best suited to accomplish this. I started with table and tablerow and initially got the results I was looking for on simpler test examples. But now I'm getting this error %DPL-1.7.6-WARNING: No results! and I can't find my bug! So yesterday I started looking at the secseparators and multisecseparators commands, but the syntax is killing me and they're just a bit too tricky for me right now (I just started learning/implementing DPL). In the DPL Manual it even suggests sticking with "table" and "tablerow", and that's what I'd like to do.
* I'd be grateful for some help figuring out where I took a wrong turn.
* One thing I saw yesterday was that I had misnamed the first parameter - i.e., Drug Code instead of Pfizer Drug Code. So I corrected that. It still didn't work. So I created a new Template:Drug Info 5 and Template:Drug Info5.dpl - suspecting that maybe there was something I wasn't aware of in the functioning of a phantom template where even if I fixed the parameter name in the dpl template, the phantom template might not pass the parameters through properly (?).
* Further down I list an example that did work. That's the one I built upon to try to get this one to work.
* Many thanks for your reply and insight. Cheers, Jeff Western cell: 323.449.7944

::Theaitetos, I much appreciate your looking at this and answering with this code. I just tried it and it works. I got my code with the phantom template to work as well, but yours is a bit cleaner of course. I do get some multiple hits on a couple of the drugs, not sure why, but I suspect it might be my error somewhere (maybe too many category tags?!); I also got multiple hits with my code.
::(7/12/12)'''''On another note, the last piece of the puzzle for this first User Story that I'm trying to solve right now is this...''''' '''Once the user is on a Disease page, how do I "automate" (from the user's pov) the selection of drug(s) that they wish to associate with the disease?''' (...which then leads to the creation of the on-the-fly-dpl-table, which is pretty much working now -- thanks again!) So, I've checked with the internal IT dept here, and Javascript drop-menus are out of the question -- too bad, seems that's the nicest way to implement this. Raw HTML is not allowed currently on the company's internal wiki (and discouraged in general), and Javascript is only allowed by changing Common.js – which is a javascript which is triggered on every page load on the wiki. So they're telling me it's very inefficient to include Javascript on their internal wiki. Okay, so the approach I just hit on yesterday (brainstorming in my head while smoking a cigar!) is to do the following:
* Created a template: <nowiki>{{DPL for EQDD Diseases List with include redirects}}</nowiki>
* This template has DPL: <nowiki>{{#dpl: |category=EQDD Diseases List |mode=none |redirects=include |format=,\n* EQDD for [[%PAGE%|%TITLE%]],, }}</nowiki>
* Then I do the template call on any Disease page where I need it and it works, producing:
:::EQDD for Age Related Macular Degeneration
:::EQDD for Allergy and Respiratory
:::EQDD for Asthma
:::EQDD for Bunionectomy
:::EQDD for Chronic Abacterial Prostatitis
:::EQDD for Crohn's Disease
:::EQDD for Crohn’s Disease
:::EQDD for Dental Pain
:::EQDD for Discoid Lupus
:::EQDD for Endometriosis
:::EQDD for Inflammation
:::EQDD for Lupus
:::EQDD for Lupus Nephritis
:::EQDD for Male Erectile Dysfunction (MED)
:::EQDD for Ophthalmology
:::EQDD for Pain
:::EQDD for Primary Dysmenorrhea
:::EQDD for Systemic Lupus Erythamatosus (SLE)
:::EQDD for Ulcerative Colitis
:::EQDD for Women's Health and Urology
*'''But here's is where I run into a stumbling block...''' '''''I've discovered that when I try to run the subst: command on dpl, I just can't get it to substitute the straight text for me, e.g., <nowiki>{{subst:{{DPL for EQDD Diseases List with include redirects}} }}</nowiki>. What it does is always gives me the dpl in the substitution. What I need''' '''''I think!''''' '''is the straight text so that I can manipulate it. Because clearly, one cannot manipulate the output from a template call, or DPL, as it is just for viewing, right. So unless there is a way, using DPL commands, to further manipulate the data (on-the-fly by the DPL) such that a user can somehow select one of the diseases (list above) -- then I don't see any other way to do this. I suppose they could just highlight the text in the page name (from the list above), copy it, and paste it into a link on that Drug page, e.g., <nowiki>[[EQDD for Ulcerative Colitis]]</nowiki>
*''''' You see, what I'm trying to do is a work-around to not having a drop-down menu option for folks to be able to select from a list of already existing Disease pages. This way, they cannot possibly enter the name of the Disease page incorrectly. So what I'm trying to do is figure out a way to take a Disease page name (exactly as you see them listed above) and turn that page name into a <nowiki>[[link]]</nowiki> on the drug page -- thus the association between the drug and the disease. Then I use the linksto= command, and I get a listing of just the drugs that have been selected and associated with a disease, displayed by the on-the-fly-dpl-table on the Disease page. Again, any suggestions would be greatly appreciated. Thank you.

:*As far as javascript is concerned: There should be some javascripts coded into the core Mediawiki css anyway, so you could try to use that stuff to do some drop-down menus. For example, try to see if the following table works in your wiki:
::* Thank you for this great suggestion! This would be a terrific solution but unfortunately it doesn't run on the company's internal wiki. I'm thinking they don't have any Javascript enabled..? When I put this table into the internal wiki, it builds a table just fine, but it's not interactive (won't expand, collapse) like it does here.

:*As for the substitution: You have to substitute a dpl-call by adding the "subst:" into the dpl-call, i.e.: <code><nowiki>{{subst:#dpl:</nowiki></code>
::* That's ''AWESOME!'' Thank you -- just tried it and it works great! You see, what I'm after is implementing a User Story where the goal is associate a drug with a disease and in order to do this, I must ensure the end-user cannot enter a link incorrectly... ergo my interest in drop-down menus! Shame they won't work on this company's wiki. Anyway, so my work-around is to grab all the disease pages (they're tagged by Category of course) and then wrap <code>[[..]]</code> square brackets around the disease page name (article name) and then instruct the end-user to copy that text exactly (with the brackets) and paste it into the Drug page. So that creates the link, which <code>linksto=</code> then uses to pull up only those Drug pages that have been ''associated'' with a particular Disease page. Of course down the road, it would be nicer to have that <code><nowiki>[[link]]</nowiki></code> get inserted in a more automated fashion -- to avoid any possibility of the user making a mistake.
:*It's hard to imagine what output you specifically desire without looking at it. Could you put one example down here, so I can see it? I.e. the direct output you desire, no dpl anything, just how you want it to look like and I'll see if I can find the proper code to produce said output.
::*Yes, I can appreciate that. That's why I wear multiple hats on this job - Business Analyst, to understand their needs and document requirements - Developer, to implement the User Stories - and PM to hopefully make all this happen in time. So next week I'm going to set about updating my User Story diagrams and I'll start with this user story, and I'll list it here for you to see. Again, many many thanks for your great suggestions. It's been a hard week -- what with going down blind alleys with subst: -- and your hint will I think get me there!
:*About having multiple results: You can disable multiple results by adding the parameter <code><nowiki>distinct = strict</nowiki></code> to your dpl call.

== php Strict Standards error, MediaWiki 1.19.1 installed on xampp 1.8.0 ==

I recently installed MediaWiki 1.19.1 on xampp 1.8.0. Yesterday I added this extension and while the pages that call it do produce a list of pages very nicely, there is also an error:

Strict Standards: Only variables should be assigned by reference in D:\xampp\htdocs\mediawiki\extensions\DynamicPageList\DPLMain.php on line 2549

I am no php mediawiki or apache hotshot, but after searching it seemed likely that the issue was overzelaous error reporting by php.

In php.ini I changed

error_reporting = E_ALL | E_STRICT

to

error_reporting = E_ALL

and restarted apache. Then I completely rem'd that line. But the error message persists. Any suggestions?

:Depending on your caching settings, the error could have been cached from before you changed the error reporting levels. Try Purging the page where the error happens.

== Using #titleparts to control the output of Subpages ==

First, great extension, glad to see it was updated! I need some help as I am having issues with subpage listing.
If I use this:
<pre>
<dpl>
titlematch=Foo/%
namespace=
shownamespace=false
nottitlematch=%/%/%
format=,\n*[[%PAGE%|{{#titleparts: %TITLE%|1|1 }}]] {{footemplate|{{#titleparts:%TITLE% |1|2 }} }},,
</dpl></pre>
Using the above, #titleparts parses just fine, all I see is the name of the parent page, exclude Foo/foo1/foo2 subpages, so all I get are the child links of the parent page, not the whole list of subpages. The first #titleparts, shows the parent name, and the 2nd #titleparts calls a template to and passes the child's name as a parameter, which adds a marker to note the page. It works great. So what is the problem?
I want to call this as a template and you can't use <nowiki>titlematch={{PAGENAME}}/%</nowiki> unless you call dpl with:
<pre>
{{#dpl:titlematch={{PAGENAME}}/%|namespace={{NAMESPACE}}|shownamespace=false|nottitlematch=%/%/%
|format=,\n*[[%PAGE%|{{#titleparts: %TITLE%|1|1 }}]] {{footemplate|{{#titleparts:%TITLE% |1|2 }} }},,}}</pre>

The list is made, but #titleparts is completely ignored in the parser call of dpl. Am I missing something? Any help appreciated because all I see is the full link to the subpage and the template call is completely ignored. Thanks [[User:Hutchy68|Hutchy68]] ([[User talk:Hutchy68|talk]]) 12:17, 16 September 2012 (UTC)

:Here the correct code:
<pre>
{{#dpl:|titlematch={{PAGENAME}}/%|namespace={{NAMESPACEE}}|shownamespace=false|nottitlematch=%/%/%
|format=,\n*[[%PAGE%¦ ²{#titleparts: %TITLE%¦1¦1}² ]] ²{footemplate¦ ²{#titleparts:%TITLE%¦1¦2}² }² ,,}}</pre>
:When you use template calls in your dpl statement, you need to escape the templates with <code>²{</code> instead of <code>{{</code> and <code>}²</code> instead of <code>}}</code>, otherwise dpl won't be able to pass variables to the included template. And you also have to escape <code>|</code> by using <code>¦</code>, otherwise the following text will be interpreted as dpl-parameter. Also, instead of <code><nowiki>{{NAMESPACE}}</nowiki></code> use <code><nowiki>{{NAMESPACEE}}</nowiki></code> since space characters need to be given as uunderline scores to work correctly.
:Yet, I wouldn't recommend the above code, as it is a lot more efficient to use the <code>replaceintitle</code> function of dpl, which allows you to have the <code>%TITLE%</code>-variable changed with a regular expression. Example, try this:
<pre>
{{#dpl:|titlematch={{PAGENAME}}/%|namespace={{NAMESPACEE}}|replaceintitle=@(.*?)\/.*$@,\1|nottitlematch=%/%/%
|format=,\n*[[%PAGE%¦%TITLE%]] ²{footemplate¦ ²{#titleparts:%TITLE%¦1¦2}² }² ,,}}</pre>
:Here, I eliminate everything in the <code>%TITLE%</code>-variable behind the first <code>/</code>. The <code>@ ... @</code> is just there to mark the beginning and end of the regex statement, you can also use other non-alphanumeric characters, but since <code>@</code> is rarely ever used in any code at all (at least in the wikis I know), I go with <code>@</code> as it stands out and can be more easily seen than slashes or something. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 13:38, 16 September 2012 (UTC)

::Thanks [[User:Theaitetos|Theaitetos]] - You beat me the punch - I just sat down to write up the fix after playing with debug=5 earlier today and realized the parser function #titleparts was being processed before being returned with the format, thus I needed to use ²{ }² to parse it after the fact because it was parsing #titleparts before <code><nowiki>%TITLE%</nowiki></code> was being returned. This of course led to knowing I needed the broken pipe ¦ instead of | and I had it working with your first example.

::I didn't use the replaceintitle= because I am need two things to pass, the '''parent title''' and the '''child title''' which are completely different. Using replaceintitle is a great idea, but the it sets <code><nowiki>%TITLE%</nowiki></code> to the value of the '''parent title''', which is the displayed link title and trying to call it a second time when I really need the '''child page name''' as a parameter it fails because <code><nowiki>%TITLE%</nowiki></code> will now return as only the '''parent name'''.

::I will change the <code><nowiki>{{NAMESPACE}}</nowiki></code> to use <code><nowiki>{{NAMESPACEE}}</nowiki></code>, I didn't think of anyone using it in a NAMESPACE like the _talk NAMESPACE. I don't think there are any NAMESPACEs on the wiki it is being used on with the break in NAMESPACE names, but it is a good idea to plan ahead. '''This is all Great stuff!''' Thanks again! -- [[User:Hutchy68|Hutchy68]] ([[User talk:Hutchy68|talk]]) 20:37, 16 September 2012 (UTC)

== After DPL pages have another category ==

I've installed DPL in a MW 1.19.2 and I used only simple codes, for example
<pre>
<dpl>
category=RedBooks_PHP
count=5
ordermethod=lastedit
qualitypages=only
</dpl>

<dpl>
category=ABAB|CGIDEV2|CL|PHP|REXX|Ruby
count=5
ordermethod=lastedit
order=descending
addauthor=true
</dpl>

[[Category:Pagine_e_categorie_di_servizio]]
</pre>

I noted that:
#With these codes I list also some categories.
#Since a category is classified for example as "CL", then also the page with the code is classified as "CL".
How can I avoid these two issue?

== Sort by custom date field? ==

This extension has been a real leap forward for the intranet wiki I'm running even though I'm only using it for the simplest of purposes, i.e displaying a feed of links to newly added content within various categories or intersections. Right now the lists are sorted using addfirstcategorydate, which is fine up to a point. But since we're adding documents and data that are sometimes older than what's already there (we're effectively building an archive) the result is sometimes confusing for users. As far as I can see the other date-sorting options (lastedit etc.) would not help. So I'm wondering if there is a relatively simple way of creating a custom date field on the page to mark content with its date of provenance and then having DPL sort by that. The capabilities of this extension appear to be amazing, but I'm afraid the advanced stuff finds me quickly out of my depth. So I'd be much obliged for any pointers anyone might have, or even to know whether I'm barking up the wrong extension here. [[User:Themicksa|Themicksa]] ([[User talk:Themicksa|talk]]) 13:21, 7 November 2012 (UTC)

:DPL can retrieve information, that you put into templates, even if those templates don't show anything. For example, if you want to mark those pages with a date, by which the pages should be sorted, then just add somewhere on that page the template date (e.g. <code><nowiki>{{timestamp|2012/11/07}}</nowiki></code>), then create the page <code>{{timestamp}}</code> as empty page or something. Now the DPL call can retrieve that by the command
<pre>
include = {timestamp}:1
</pre>
:Depending on how your DPL call is structured you can then sort by this value; for example, if you use a table, just add the column "Date" to the table, where the retrieved timestamp shows up and then sort by this table column <code>tablesortcol = 5</code>, if "Date" is the fifth column. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 18:16, 7 November 2012 (UTC)

::Wow. Thanks for the quick reply. Even better I think I understand that solution and look forward to trying it out. [[User:Themicksa|Themicksa]] ([[User talk:Themicksa|talk]]) 20:42, 7 November 2012 (UTC)
:::OK. Progress of a kind. The timestamp template solution works and although the content isn't normally within a table (and doesn't otherwise need to be) I have got close to what I need using the following code:
<pre>
{{#dpl:
|category= Good News
|category= UK Grants
|category= International Grants
|notcategory= Global
|notnamespace= Category
|include = {timestamp}:1
|table=class="prettytable"
|tablesortcol = -2
}}
</pre>
This gives me a list of page titles followed by the timestamp date that are sorted with latest at top--all great. I've used an existing table class and can create a more suitable one if needs be, but I'm wondering if there is a way of doing it without the table (i.e. is tablesortcol the only way of sorting the timestamps.

Also, I'd like to use different date format; is that governed by the format in the timestamp template or can it be set via the DPL? (I'm presuming that the ordermethod= option is redundant here.)

Finally i'd like to include a bullet at the front of the line. I tried playing around with the example in the Manual
<pre>
|format = ,\n* [[%PAGE%|%TITLE%]],,
</pre>
but it doesn't work when used along with the table= parameter and I'm not sure how or where to place {timestamp} in that. In short, can I also use format= to give me this: • Pagename dd/mm/yyy

Thanks again for your help Theaitetos and even more thanks if you can shed any more light in my dimness.

::Using the bulletpoint-syntax inside a table is already a little bit tricky in Mediawiki itself, as |* would just give you a line starting with a mere *. Although an additional newline would do the job, it isn't really necessary, as we can simply put the bulletpoint wherever we need it manually.

::As for "format": When you use the format= parameter, every other formatting is suppressed, so you have to write down everything you want as output using the given variables; i.e. you can't use table= along with it, but you can write down a table in the format= parameter:

|format = {¦ , \n¦- \n¦ • ¦¦ [[%PAGE%]] ¦¦ , , \n¦}
</pre>
::and then you should be able to use <code>tablesortcol = 3</code> to get the job done, as the included content will simply appear at the position of the 2nd comma. If you want the Mediawiki bulletpoint, you would have to replace the <code>•</code> with <code>\n*</code>. Sorting output outside of tables is atm only possible with the DPL intrinsic parameters and none of them helps you in this case, so you will have to use a table. But since tables are highly customizable, that shouldn't be a big layout problem, just add the desired css-style right after the "{|" table beginning.

::The content of the [[template:timestamp]] is irrelevant to the output, but what you enter in the respective pages is what is important as that is the included content, so when you write down <code><nowiki>{{timestamp|2012-11-09}}</nowiki></code> on [[Olympics 2012]] then <code>• [[Olympics 2012]] 2012-11-09</code> is exactly what appears. And when you write <code><nowiki>{{timestamp|"2012-11-09"}}</nowiki></code> then you get <code>• [[Olympics 2012]] "2012-11-09"</code>. DPL isn't doing anything with the transcluded content here, it just repeats what is written on the respective page. So you would have to change those pages in the way you want it to appear. -[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 16:41, 9 November 2012 (UTC)

:::Thanks once again for the help which I'm only just now finding the time to implement. Unfortunately, I'm now floundering. I can get the display I require by using the following:

:::I got that through trial and error so I'm not sure I understand everything. This gives me a bullet followed by the pagename, followed by the timestamp date as entered on each page (aligned to the right). However, the items are not ordered by the date stamp. Is the tablesortcol ref wrong? Or perhaps the timestamp template is at fault:
<pre>
Template is: —Post date: {{{1}}}
ON the page is: {{Timestamp|2012/11/29}}

:::btw The timestamp sort was working in my earlier attempt, but ideally I would like that to be sorted AND displayed in a different format, ie dd/mm/yyyy. Can that be handled within the DPL code or is it a function of the timestamp.

== Passing parameters from DPL to Semantic MediaWiki ==

I'm trying to created a template that will output a dynamic report by generating a list of pages with Dynamic Page List and then run queries on each page using Semantic Mediawiki, outputting the whole mess in a table. The structure of the template looks like this:

<pre><nowiki>{| class="wikitable sortable collapsible collapsed" width="100%"
|- valign="bottom"
! width="15%" | Compound ID
! width="15%" | Generic name
! width="15%" | Trade name
! width="15%" | Developer
! width="10%" | Phase of development
! width="30%" | Target

{{#dpl:
| category=compounds
| linksto={{PAGENAME}}{{#dpl: linksto={{PAGENAME}} | redirects=only | mode=userformat | format=,{{!}},%TITLE%, | suppresserrors=true }}
| ignorecase=true
| distinct=strict
| format=,{{!}}- valign="top"\n{{indication-based compound list/row|%TITLE%}}\n
| noresultsheader={{!}}-\n{{!}} colspan="6" align="center" {{!}} ''No compounds have yet been studied for this indication.''
}}

|}
}}</nowiki></pre>

The row formatting template, <code><nowiki>{{indication-based compound list/row}}</nowiki></code>, consists of the following:

<pre><nowiki><includeonly>{{!}} {{#show: {{{1}}} | ?compound id }}
{{!}}{{!}} {{#show: {{{1}}} | ?compound generic name }}
{{!}}{{!}} {{#show: {{{1}}} | ?compound trade name }}
{{!}}{{!}} {{#show: {{{1}}} | ?developer }}
{{!}}{{!}} {{#ask: [[category:clinical studies]][[compound number::{{{1|}}}]]
| ?study phase=
| limit=1
| mainlabel=-
| searchlabel=
| sort=study phase
| order=descending
}}
{{!}}{{!}} {{#show: {{{1|}}} | ?target }}</includeonly></nowiki></pre>

The <code>{{#ask}}</code> query is the reason why this isn't just a straight-forward DPL table: because the current phase of clinical development of a specific compound for a specific indication is a dynamic piece of data that changes frequently, the only option seems to be using an <code>{{#ask}}</code> query to find out the highest value for study phase among the clinical trials that meet the parameters. But this template will be surveying auto-generated pages and I don't have a way of auto-loading a list of indications for each compound (to apply semantic markup to), so instead it's generating based on lists of indication links that are themselves generated by a <code>{{#dpl}}</code> function on each compound page.

I've walked through this step by step, and none of the following are the problem:

# The template code is sound, and generates the proper structure.
# The table row template is sound, and if I remove the <code>{{#dpl}}</code> function and replace it with the template and a compound page name as a parameter, e.g. <code><nowiki>{{indication-based compound list/row|infliximab}}</nowiki></code>, it creates exactly the output I'm looking for.
# The <code>{{#dpl}}</code> function produces the correct list of pages when using the default output format.
# The <code>{{#dpl}}</code> function passes the list as sequential parameters properly when using <code>format = ,{{template}}</code> with a simply dummy template (just an unordered list).

However, when I put all the pieces together I just get empty table cells. The <code>{{#show}}</code> and <code>{{#ask}}</code> functions can't seem to accept the DPL input as parameters. Is there an additional argument or intermediate step I'm skipping that can sanitize the input and make the whole thing work? Or are DPL and SMW fundamentally incompatible in this way?

* DynamicPageList 2.01
* Semantic MediaWiki 1.8
* MediaWiki 1.20.2
* PHP 5.3.19 (apache2handler)
* MySQL 5.1.30

Thanks!

::I am not too familiar with the SMW extension, but this isn't the first time, that suggests incompatibility issues between the two extensions, i.e. each of them works fine on its own, but they fail when put together. Having them work together fine requires changing the very code of the two extensions, which at this moment is very unlikely to happen. Yet, I might have an idea as to how you can achieve what you want: You will need to install the [[Extension:Variables]] and instead of calling upon the template {{Template|indication-based compound list/row|%TITLE%}} directly, you can use the primary DPL call to define variables, which you can then use to call the template after the DPL call itself. So place the dpl call above your table and change it as follows:
<pre>
|format = , ²{#vardefine:%NR%¦%PAGE%}² ,,
|resultsheader = ²{#vardefine:TOTAL¦%PAGES%}²
</pre>
::This DPL call will produce no visible output, but now the variable {{#var:TOTAL}} gives you the total amount of pages that were found by the DPL call and the variables {{#var:1}}, {{#var:2}}, {{#var:3}}, ... will give you said pages. You should then be able to use the template {{Template|indication-based compound list/row|{{#var:1}}}} and so forth to produce your table output without another DPL call (which might erase your variables). It's not the most straightforward way, but the only one that comes to my mind atm. Good luck! --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 12:55, 23 February 2013 (UTC)

== Tablerow parameter including too many columns ==

In my wiki (concerning beekeeping in the game Minecraft), I want to build on an overview page a list of all bees, which have a certain temperature tolerance. Each bee uses several templates on its page. The relevant ones here are ''Bee'' and ''Attributes''. The ''Bee'' template gives me the information I want displayed via the tablerow parameter, the ''Attributes'' template gives me the parameter, on which includematch selects the bees.

Code I tried:
<pre>
{{#dpl:
|category = Bees
|includematch = ,/temp-tol\s*=\s*\-2\s*\R/i
|include = {Bee}:name, {Attributes}:temp-tol
|table = class="wikitable",-,Down 2
|tablerow = [[File:Bee-%%.png|32px]] [[%% Bee]]
}}
</pre>
Result:
Selection works, but the table has two columns. The first one has the picture and textual link to the article as I want, the second one (unwanted) gives me the content of the temp-tol variable. According to the DPL-Manual: "Skipping a column would suppress output for that column completely.", but I don't define a second column (neither in table, nor in tablerow), so I expected to get a single column table.

I can workaround this by using a surrogate template for Attributes, which only contains a ''&nbsp;'', but is it possible without this? At what point lies my thinking error? --[[Special:Contributions/137.226.119.115|137.226.119.115]] 20:07, 22 February 2013 (UTC)

:I think the manual is out of date on this one. To make things easier for new users, the default has changed to always add colums, when there is more content included via the "include=" statement. In order to not have it, you need to manually suppress the visible output. I recommend changing the last line to:
<pre>
|tablerow = [[File:Bee-%%.png|32px]] [[%% Bee]] «nowiki»,«/nowiki»
</pre>
:If you want to, you could even put the temp-tol output invisible in front of the image and use it for sorting purposes. Tell me if it doesn't work out and I have another look at it. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 12:33, 23 February 2013 (UTC)
::Thank you very much, it worked perfectly. --[[Special:Contributions/137.226.119.115|137.226.119.115]] 23:33, 24 February 2013 (UTC)

== Tablerow parameter - Use of default values possible? ==

First the code:
<pre>
{{#dpl:
|category = Bees
|includematch = /prod-s\s*=/i, /(humid{{!}}temp)\s*=/i
|include = {Bee}:name, {Attributes}:temp:humid
|table = class="wikitable sortable",-,Bee,Temp,Humid
|tablerow = [[File:Bee-%%.png|32px]] [[%% Bee]],%%,%%
}}
</pre>
The template parameters for the Attribute template (temp and humid) can sometimes be empty. Is it possible to display an alternative text for these cases in the tablerow parameter?

Code I tried:
<pre>
|tablerow = [[File:Bee-%%.png|32px]] [[%% Bee]],{{#if: %% {{!}} %% {{!}} Normal}},{{#if: %% {{!}} %% {{!}} Normal}}
</pre>
* Line of reasoning: IF %% is non-empty THEN display %% ELSE display 'Normal'.
* Result: Empty cells everywhere in column 2+3, independent of the usage of the temp or humid parameter.
** I've found the error myself. The code which works is:
<pre>
|tablerow = [[File:Bee-%%.png|32px]] [[%% Bee]],²{#if: %% {{!}} %% {{!}} Normal}²,²{#if: %% {{!}} %% {{!}} Normal}²
</pre>

:Hallo. Das Problem dürfte hier in der Zeile <code><nowiki>|includematch = /\s*Ort\s*{{=}}\s*{{{Name|}}}/si</nowiki></code> stecken, denn Zeichen wie <code>(</code>, <code>)</code> oder <code>+</code> sind [[de:Metazeichen#Metazeichen in regulären Ausdrücken|RegEx-Metazeichen]]. Wenn also ein solches Metazeichen in <code><nowiki>{{{Name|}}}</nowiki></code> vorkommt, funktioniert es nicht. Du musst die Metazeichen also erst per <code>\</code> entwerten, sodass sie als normale Zeichen aufgefasst werden. Das kannst du bspw. durch <code><nowiki>{{#replace:{{{Name|}}}|+|\+}}</nowiki></code> für das <code>+</code> erreichen. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 19:48, 31 March 2013 (UTC)

:::Eine weitere Kleinigkeit: Bei RegEx-Ausdrücken wie <code><nowiki>includematch = /\s*Ort\s*{{=}}\s*{{{Name|}}}/si</nowiki></code> sollte man das <code>=</code> eigentlich ohne Vorlage verwenden können. Und zur Übersichtlichkeit verwende ich als Anfangs- und Endzeichen immer ein <code>@</code>, da dass ja praktisch nie vorkommt in Parameterwerten, es würde also so aussehen: <code>includematch = @\¦\s*Ort\s*=\s*{{{Name|}}}@si</code> (das <code>¦</code> ist das Ausweichzeichen für <code>|</code> in DPL; man kann alternativ aber auch <code>{{Template|!}}</code> verwenden).

:You can use phantom templates for that purpose.

Hi,

Is there a way to get DPL running on a Mediawiki 1.6.9 ? If not, why exactly ?

Currently the latest version is on the [http://semeb.com/dpldemo/Download dpldemo page]. But this will change in the near future. Mediawiki SVN repository will become the official source for distribution. [[User:Algorithmix|Algorithmix]] 09:22, 21 May 2009 (UTC)

== Tweak to make DPL backward compatible with DynamicPageList2 <suppresserrors> parameter ==

I'm one of the admins at ChoralWiki (www.cpdl.org), a free Public Domain scores library, and we use [[Extension:DynamicPageList2|DynamicPageList2]] a lot in it with parameter <suppresserrors> set to 'true'. We were doing an upgrade test to the newest version of DynamicPageList and after the upgrade all our DPL queries started showing this warning:

%DPL-1.7.4-WARNING: Unknown parameter '$0' is ignored. Help: available parameters: suppresserrors.

After a quick research we realized that parameter <suppresserrors> is no longer supported by the new DPL versions. It would be a pain to edit all pages where it appears, so we decided to tweak the DPL code to recognize it and behave as expected. We made the changes below, tested it and it worked fine. So we decided to post it here in case someone else faces the same problem. All one needs to do is to add the following lines in red to file ''DinamicPageList2.php'':

line 682:

/**
* noresultsheader / footer is some wiki text which will be output (instead of a warning message)
* if the result set is empty; setting 'noresultsheader' to something like ' ' will suppress
* the warning about empty result set.
*/
'suppresserrors' => array('default' => 'false', 'true', 'no', 'yes', '0', '1', 'off', 'on'),
'noresultsheader' => array('default' => ''),
'noresultsfooter' => array('default' => ''),

line 1157:

$bSuppressErrors = self::argBoolean(self::$options['suppresserrors']['default']);
$sResultsHeader = self::$options['resultsheader']['default'];
$sResultsFooter = self::$options['resultsfooter']['default'];

line 2095:
case 'noresultsheader':
$sNoResultsHeader = $sArg;
break;
case 'suppresserrors':
if( in_array($sArg, self::$options['suppresserrors'])) {
$bSuppressErrors = self::argBoolean($sArg);
if( $bSuppressErrors )
$sNoResultsHeader = ' ';
}
else
$output .= $logger->msgWrongParam('suppresserrors', $sArg);
break;
case 'noresultsfooter':
$sNoResultsFooter = $sArg;
break;

After the change, if <suppresserrors=true> is used in the query and 0 pages are returned, it won't show any warning message; if <noresultsheader='text'> is also used, it will show the 'text' supplied. [[User:Capmo|Capmo]] 13:40, 18 September 2008 (UTC)

== Index (List of index-terms) for a book ==
I am experienced in editing wikipedia-articles. Now I want to use mediawiki on my server to write a book (around 1.000 articles). I want to mark index-terms in articles and have one page with a sorted index.
The book will exist of 1.000 articles. So it is no problem to generate the article dynamicaly when I will open the index.
Is DPL the right extension to do the job?

How to mark the index-terms in articles?

: Regards, Jan

::Hello Jan, creating a permuted index is a challenge because DPL normally walks sequentially through all articles which match the selection criteria and collects the desired information (in your case template invocations). In your case one would have to store the collected data (using the ''arrays'' extension ), re-arrange the order and then produce the output in a final step. With less than 10 lines of code all this is possible:
::<center>see     ''' http://semeb.com/dpldemo/index.php?title=DPL_Example_017 ''' </center>
::I know SMW and think it is powerful for expert users. The idea of DPL is to use MW as it is without introducing new syntax for those users who ''write'' articles.

== Problems ==

Hi. I have a problem with labeled section transclusion, the ''section'' tags show up along with the transcluded text. This problem only showed up recently; the page was doing fine four months ago when I left it. When I came back a few days ago, no changes have been made to the articles but the DPL pages have broken formatting. It is a Wikia page and I asked the Wikia staff about it too, but they haven't recognized something from their end being the source of the problem either. So here's the problem. Instead of this:

http://img.photobucket.com/albums/v59/daarklord/ForumGraphics/DplWtf01.gif

I get this instead:

I installed the extension on a private wiki according to the notes on the page (#include("$IP/extensions/intersection/DynamicPageList.php");), but it doesn't work. When I disable (commtenting out) the extension in the localsettings.php, I can see the page. If I enable the extension I only get a white page displayed on pages with <DynamicPageList></DynamicPageList>, all other pages can be edited and shown.

==A Bug?==
I use DPL together with MediaWiki 1.14.0, SMW 1.4.2, DPL 1.7.9 If I follow a link, that is done by the Call-Extension, the CSS-File of SMW is not included. What can I do? The main problem: The field “smwsortkey” is not more hidden, because the style for it is not included. Christian Weiss 14:44, 27 May 2009 (GMT+2)

:Please give more details. I assume that the problem has nothing to do with DPL; this means that it also occurs if you use the Extension:Call from the browser's URL-line or within a normal document like this <nowiki>[[Special:Call/:Mypage,a=b]]</nowiki>. I don´t understand your remark about a "style". Are you talking about css? Can you reproduce the error on the [http://semeb.com/dpldemo dpldemo website]? It has DPL 1.7.9 and SMW 1.0 installed.

:::It's like you said: I call a Template by the Call-Extension, the DPL-Calendar ":Current events" for example. If it's included the normal Way in a Page, in the HTML-Source the "SMW_custom.css" and the "SMW_sorttable.js" are included. If the Template ist called by the "Call"-Extension those files are not included in the HTML-Source. A workaround ist to include those files in the Common.css and Common.js for Skins, so it is included everytime. For the SMW_sortable.js I get then 2x sortbuttons :-) I think, the Call-Extension ist part of your Pakage, so I write my Problem to you. Christian Weiss 10:06, 06 Jun 2009 (GMT+2)

== LoF ==

I sthe LoF ment to be set as global in LocalSettings? I'd prefer it as option per DPL call. So I want to use a complex DPL call I would set LoF = 3 or sth inside the call. But if I want to run a very simple call I would set LoF = 0 to save some ressources. --[[User:Subfader|Subfader]] 15:15, 17 June 2009 (UTC)

:Currently the Level of Functionality is a configurable option which is global for the whole use of DPL in a wiki. It is meant to be a "protection belt" against abuse.

== DPL Doesn't Work after MW Upgrade from 1.13 to 1.15.1 ==

Hi, I have a private wiki we use as a content Management system at work. I updated the wiki from MW.1.13 to MW.1.15.1, and suddenly DPL doesn't work. For example, I have a page for each of our main applications, with a supbage called 'Troubleshooting'. Below that are more subpages, one for each troubleshooting document. The '/Troubleshooting' subpage consists entirely of DPL to list the child subpages for a user to browse and jump to.

For example (changing the page names to protect proprietary information):

We have a set of pages like so:

* Main:Zazaza
* Main:Zazaza/Troubleshooting
* Main:Zazaza/Troubleshooting/Error 51 - File not Found
* Main:Zazaza/Troubleshooting/Can't Save Configurations
* Main:Zazaza/Troubleshooting/App Crashes if User Chews Bubble Gum

The top page, Main:Zazaza, describes the application and has a link to Main:Zazaza/Troubleshooting.

Main:Zazaza/Troubleshooting consists entirely of DPL code that will list the three 'troubleshooting' child subpages with links. This page's DPL Code is as follows:


<DPL> 
titlematch=Zazaza/Troubleshooting/% 
notnamespace=Image 
notnamespace=Image_talk 
notnamespace=Template 
notnamespace=Template_talk 
replaceintitle=/.......Troubleshooting./, 
</DPL>


Previously, the DPL worked, and a user browsing to the Zazaza/Troubleshooting page would see a list of clickable links:

Error 51 - File not Found
Can't Save Configurations
App Crashes if User Chews Bubble Gum

Now, since the 1.15.1 upgrade, all that shows up is the following:

Extension:DynamicPageList (DPL), version 1.8.6 : <dpl_log_1>

Before you ask, no, there is no log being generated or updated anywhere within my wiki home that provides me with a clue as to why DPL isn't working.

I confess to being confused because when I originally downloaded DPL in May or June 2008, this was during the time frame that "old DPL" was known as "Intersection" and 'this' DPL was just known as "DPL", and at the time there wasn't even a reference to the forked versions on the extension page. (I only came to learn all of this with my research this past week.) However, I have verified that I am using semeb.com's Dynamic Page List (was using v.1.6.9, now using v.1.8.6.) I downloaded v.1.8.6 earlier in the week from http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/DynamicPageList/, and I just re-obtained the files from the ZIP archive available at http://semeb.com/dpldemo/images/f/fe/Semeb_extensions.zip and redeployed them to be certain. The behavior is still the same as above.

Any help would be appreciated.

== Parsing Pipes ==

I have run into a little bit of a quandary which I am trying to solve. I am trying to create a template with a set of parameters that are passed from a dynamically created list from DPL. However, when using the pipe character in the formatting for DPL like this:
<pre>{{Hot_issues
|<DPL>category=Application
category=Hot_issues
format=,|,[[%TITLE%]],
notnamespace=Category
noresultsheader=Nothing found...</DPL>}}
</pre>
...the pipe character is not parsed by the templating system, I think because of the order in which things are processed... The result is all the articles listed like this: "|Article1|Article2", and so on, instead of passing each one as a template parameter. I have been trying, but I can't think of a way around this. Does anybody have any thoughts on this? --[[User:Bsmithme|Bsmithme]] 21:12, 18 July 2009 (UTC)

== RESOLVED: Fatal error ==

After upgrading my wiki to MW 1.15 I got the error message:
<pre>Fatal error: Unsupported operand types in /home/schlott/public_html/wiki/includes/parser/LinkHolderArray.php on line 33</pre>
and the extension stoped working.

The solution was inside the DynamicPageList/DPL.php with the following statement in Line 36:
<pre>
// cloning the parser in the following statement leads in some cases to a php error in MW 1.15
// You must apply the following patch to avoid this:
// add in LinkHoldersArray.php at the beginning of function 'merge' the following code lines:
// if (!isset($this->interwikis)) {
// $this->internals = array();
// $this->interwikis = array();
// $this->size = 0;
// $this->parent = $other->parent;
// }
</pre>

After adding the mentioned code lines to LinkHoldersArray.php the extension works just fine. -- Flaming Moe

== Comment on differing versions by [[User:Algorithmix|Algorithmix]] ==
* Note that the version running on Wikimedia sites was at some point in time renamed to [[Extension:Intersection]] to avoid confusion with the extension described here. But the documentation still was talking of "DynamicPageList" and the SVN path was not renamed.
* Recently 'Intersection' claimed back its ancient name and that is why you now find the documentation of 'Intersection' under 'Extension:DynamicPageList'.
* On the other hand the DPL extension described here was still named 'DynamicPageList' and new functions were added. At some point in time downward compatibility with the version running on Wikimedia sites was lost. The extension was renamed to 'DynamicPageList2' but the documentation was still talking of "DynamicPageList".
* Then another bunch of functionality was added and downward compatibility (with DPL2) was lost. The name of this version was changed back to DPL (which was thought to be 'free').

''All this has created much confusion. Read below for a suggestion on how to re-unite the different variants.''

This extension '''Dynamic Page List (DPL)''' has the same roots as [[Extension:Intersection]]. Until recently DPL was almost - but not exactly - downwards compatible with ''Intersection''. A lot of confusion comes from the fact that ''Intersection'' uses the tag <DynamicPageList> whereas '''Dynamic Page List (DPL)''' uses the tag <DPL>.

DPL offers functionality '''that goes far beyond''' ''Intersection''. Some of this functionality might be useful also on Wikimedia sites. But the problem is that inexperienced users or people with 'not-so-good-intentions' might write DPL statements which create significant database load.

A good solution - which also puts an end to all naming ambiguities of ''DynamicPageList, DPL, DPL2'' and ''Intersection'' looks like this:
# There should be only ONE extension.
# It should be called ''DynamicPageList'' (short name DPL).
# It should listen to the tags ''DynamicPageList'' and ''DPL'' for compatibility reasons.
# Its sources should be in the mediawiki SVN
# It should be strictly downward compatible with ''Intersection''.
# It should offer a configuration switch (let us call it LevelOfFunctionality = LoF) which lets the administrator of a wiki decide, how much functionality will be offered to the users:
#* LoF = 0 is exactly identical with ''Intersection'' as of today.
#* LoF = 1 offers additional features which do not affect performance (mainly related to output formatting)
#* LoF = 2 offers additional features which are on the same conceptual level as ''Intersection'' like selection of pages by use of templates or by pagelinks. As the underlying table structures in the mediawiki database design are very similar to categories the performance cost of theses features are comparable in magnitude with ''Intersection'''s current features
#* LoF = 3 offers additional features which are more cost-intensive, like e.g. content transclusion from pages that occur in the DPL result; we think that a dedicated DPL cache could allow to offer these features also on high traffic sites - but this still has to be proved
#* LoF = 4 offers a last group of features which are a somewhat exotic and could create trouble if used by ignorant people (batch updates and batch deletions based on DPL query results)

:My own thoughts on this: it's a good idea, but performance is a huge consideration. I suggest investigating ways to avoid loading DPL code unless it is required, particularly [[Manual:$wgAutoloadClasses|$wgAutoloadClasses]]. Right now APC shows that it is touching all the code on every page access, and that's a significant cost when you have a large number of pages being accessed.

:::Ah, indeed it does - thank you! I was using 1.8.6 and it seems you made that change in 1.8.7 - I updated to 1.8.8 and now only DPLSetup.php is showing up on each load.

== Trying to List Pages... ==
Trying to List Pages within a Namespace in Category Mode, Alphabatized on a non category page. Sounds ridiculous however this is the syntax that i am using:
<pre><dpl>
namespace=Article
shownamespace=false
mode=category
ordermethod=category,title
</dpl></pre>
What i am trying to do is show all pages in the article namespace on a page in category mode alphabetized by the page title rather then the namespace. Currently all pages are organized under "A" because the pages are named Article:Page Name. I want to eliminate or mask the Article so that they are organized by Page Name.

Kevindank AT Gmail.com

:Hmh, you aren't very clear.
:1) is there really a custom namespace called "Article"? Cos otherwise you mean Main: "namespace="
:But I guess I know what you mean. Like in [http://semeb.com/dpldemo/index.php?title=User:Subfader/Olli1/O7 this example] you don't want U headings but 0-Z... I dunno a solution :/ --[[User:Subfader|Subfader]] 21:17, 21 October 2009 (UTC)

===Workaround ===
If you apply a very small patch you can use
ordermethod=titlewithoutnamespace
to get the desired result:

find (near line 1860 in DPLMain.php in the latest version)
case 'titlewithoutnamespace':
and add the following line immediately after that line:
$sSqlSortkey = ", $sPageTable.page_title ".$sOrderCollation." as sortkey";

I will add this code line to the next release.
In fact, the patch will make the new behaviour the default (which is o.k., I think). Use <tt>ordermethod=title</tt> to switch to the old behaviour.

==DISPLAYTITLE and DYNAMIC PAGE LIST==
is it possible to tie this to DISPLAYTITLE to sort pages by their DisplayTitle?

==installation instruction problems==
Thanks for this powerful extension. In order to help others to use it, I want to report two problems I just had in following the installation instructions in the article.

The instructions say:
add include("$IP/extensions/DynamicPageList/DynamicPageList.php"); to LocalSettings.php
However, the actual file downloaded for v1.14 was named DynamicPageList2.php. This modification worked:
include("$IP/extensions/DynamicPageList/DynamicPageList2.php");

The second problem is probably due to my lack of familiarity with PHP. The instructions appear to say to add a function call in LocalSettings after the include() statement above to control the richness level, like this:
ExtDynamicPageList::setFunctionalRichness(3);
However, this caused a fatal error, so I commented it out. Should the call be like this?
DynamicPageList2::setFunctionalRichness(3);

== Having DPL Maintain #section Links ==

If the pages I'm building my DPL from have links like <tt><nowiki>[[#section|A Section]]</nowiki></tt>, is it possible to to have DPL maintain the url of the page with that specific section, rather than have it change it to the page that has the DPL on it? — [[User:Cosmotron|Cosmotron]] 18:56, 8 November 2009 (UTC)

== Template:DPL_Extension creation as potential redirect loop ==

There is a DPLSetup.php routine, commonSetup(), which attempts to create an <nowiki>{{Extension DPL}}</nowiki> template using the userid of the first user to visit the wiki after the extension is installed:

<source lang="php">
private static function commonSetup() {

if (!isset(self::$createdLinks)) {
self::$createdLinks=array(
'resetLinks'=> false, 'resetTemplates' => false,
'resetCategories' => false, 'resetImages' => false, 'resetdone' => false , 'elimdone' => false );
}

// make sure page "Template:Extension DPL" exists
$title = Title::newFromText('Template:Extension DPL');
global $wgUser;
if (!$title->exists() && $wgUser->isAllowed('edit')) {
$article = new Article($title);
$article->doEdit( "<noinclude>This page was automatically created. It serves as an anchor page for ".
"all '''[[Special:WhatLinksHere/Template:Extension_DPL|invocations]]''' ".
"of [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)].</noinclude>",
$title, EDIT_NEW | EDIT_FORCE_BOT );
die(header('Location: '.Title::newFromText('Template:Extension DPL')->getFullURL()));
}

}
</source>

Two issues with this:
* (minor) The external link [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)] points to a disambiguation page here instead of to the actual extension info.
* (not so minor) If creation of the template fails, the user is redirected to [[Template:Extension DPL]] regardless, and the failed attempt to create the template is repeated until the browser detects this as a redirect loop and shuts down.

I've noticed that new installs, if started with just a blank set of database tables and a LocalSettings file (without running the MediaWiki installer again for the new wiki), are prone to go into an endless HTML redirect loop because of this code. Attempts to run maintenance/update.php from the command line may also abruptly end with errors if the extension is trying to create this page during the "update.php" run and the database is not yet updated to the latest MW format (and therefore not ready for the template creation attempt).

There needs to be some error handling; if the creation of the placeholder template fails, don't just keep trying forever - at least not if this is going to return errors or redirect loops. --[[User:Carlb|Carlb]] 14:12, 9 November 2009 (UTC)

== [SOLVED] White page after including Semantic Media Wiki Extension in LocalSettings.php ==

Hello,
I installed the Semantic Media Wiki extension on a Media Wiki 1.16.0
According to the install notes on the page I appended the following two lines to the LocalSettings.php:
 
include_once("$IP/extensions/SemanticMediaWiki/SemanticMediaWiki.php"); 
enableSemantics('filerepos.de'); 
 
After that I get a blank page on every URL of the Wiki.
Set error_reporting to E_ALL (in LocalSettings.php, SMW-Config-Files) but also got a blank page.

Also tried the hint from the Semantic Wiki Site with no success:

ini_set( 'memory_limit', '100M' );

When I comment the both lines out everything works again.

(Setup: Mediawiki 1.16.0, PHP Version 5.2.6, MySql 5.0.45, Semantic Media Wiki Extension 1.5.3 stable)

Would apreciate any hint.
:This page is only for support for the DynamicPageList extension. You're more likely to get a response if you ask the SMW people. With that said, Did you add the:
error_reporting(E_ALL);
ini_set("display_errors", 1);
as the very first lines of LocalSettings.php (directly below the opening <?php )? If that still doesn't work, try setting error reporting to E_ALL directly in your php.ini file. You can also try checking your webserver's error log as well (doesn't usually have php errors in it, but if its some sort of config problem with your webserver it might have relevant information). [[User:Bawolff|Bawolff]] 22:31, 26 November 2010 (UTC)

 
Thanks for the reply...think ini_set got the errorReporting working.
Now there is some output I can work with:
http://www.mediawiki.org/w/index.php?title=Extension_talk:DynamicPageList_(third-party)&action=edit&section=38
Call to undefined function enableSemantics() in /srv/www/vhosts/filerepos.de/httpdocs/websites/semwiki/LocalSettings.php on line 138

[SOLVED] I accidently downloaded the wiki and the extension with different user...so the wiki wasnt allowed to access the extension.
Changed extension files owner to the same owner as the wiki and so everything works now.
Thanks for the error reporting hint which allowed me to find my mistake

== Undefined index and .default ==

I try to make the DPL-Extension read out a category and get the parameters of a template in the articles of this category. They are meant to be used in another template. I saw another wiki which did it the same way as I did, but I get a strange Error while using the preview on this:

<pre><DPL>
category = Some Category
mode = userformat
includepage = {Template in articles} Kr
allowcachedresults = true
</DPL></pre>

"Notice: Undefined index: tip ... EditPage.php". The line is this: "$tip = $tool['tip'],".
This is strange but probably not that important. The real problem I got ist, that the extension always adds an ".default" at the end of the template. So I get a long list which just says "Template:Template in articles Kr.defaultTemplate:Template in articles Kr.default...".I don't really get the origin of the problem and couldn't find an answer anywhere.
I didn't change anything in the basic code of mediawiki, except for some extra buttons i added in EditPage.php. There are also no extensions, that could affect the DPL extension.--[[User:Eski123|Eski123]] 12:14, 2 January 2010 (UTC)

:My five cents on this: according to [http://semeb.com/dpldemo/index.php?title=Includepage#include_contents_related_to_templates doc], the DPL engine calls a template with the additional sufix ".default" when a page listed in the result does not use the specified template. [[User:Pierrem100|Pierrem100]] 14:49, 26 October 2010 (UTC)

== Problems with missing subheads ==

DPL is apparently crashing when used with a subhead that doesn't exist on one of the pages included by Category.

I have the following DPL code on a page called "Current projects":

=Projects in process=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects
|include = #Project steward, #Need
|includetrim=true
|table=class="sortable", Project, Steward, Need
}}

=Completed projects=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects, completed
|include = #Project steward, #Final accounting
|includetrim=true
|table=class="sortable", Project, Steward, Final Accounting
}}

The first DPL call works if I temporarily clip out the second DPL cal, but including the second DPL call displays:

:Fatal error: Call to a member function getPrefixedDBkey() on a non-object in /Library/WebServer/EcoReality/wiki/includes/parser/Preprocessor_DOM.php on line 994

I then looked over the pages in the Category "Projects, completed" and discovered several of them did not have a subhead called "Final accounting." These are old pages, and this worked once upon a time!

For now, I've removed "Final accounting" from the second DPL call, but it seems it should behave better than this in such a case, no? Have I messed up something to cause it to misbehave this way?

See it fixed at: http://www.ecoreality.org/wiki/Current_projects .

== Spaces and underscores ==

It seems that the "titleregexp" parameter doesn't interpret spaces and underscores the same way. In fact, since page names can't have spaces in them, any time there is a space it just flat out fails. This would ordinarily not be such a big deal, so, okay, you learn not to use spaces, however i have a template for detecting direct subpages of a page (but not sub-subpages). the regexp is {{PAGENAME}}/[^/]*$ however, if used on a page with a space in the name, {{PAGENAME}} returns a space there where dpl requires an underscore. It seems to me that spaces and underscores should be totally interchangable in dpl, as they are in the rest of MW. [[User:DeFender1031|DeFender1031]] 11:22, 29 January 2010 (UTC)

Dug into the code a bit and it seems like DPL clones the parser and does a clearState(), maybe that clears the active cite object as well for some reason? Anyone else have this problem? Is there a workaround? I'm running MediaWiki 1.15.1, DPL 1.8.9 with PHP 5.2.6. --[[User:Shadowie|Shadowie]] 15:02, 27 February 2010 (UTC)

== Great and easy: Searchable Tables ==

I use the TableTools (Firefox-Extension) to search the tables generated with DynamicPageList (Mediawiki-Extension); see here [https://addons.mozilla.org/en-US/firefox/addon/2637]

With the Firefox-Extension installed you can right-click into a table and choose
# show Filter (german: Filter anzeigen)
# show Searchfilter (german: Suchfilter anzeigen)

With the first you get lists where you can choose an item in the table-heading and get all the rows matching this item.

With the second you get searchfields in the heading to use for a wildcard-search.

Both functions are very (!) usefull for the DynamicPageList-tables. But it is not userfriendly for less sophisticated users to right-click to get the function. I would like to put such functionality with an easy dpl-command into the heading, similar to the magicword "wikitable" or "sortable": "searchable". Now I wonder if it would be possible to integrate such a great feature directly into DynamicPageList??

I hope that others are also interested in such a feature.

Hi, it seems that all parameters are set in a template. In my wiki, there is a pretty standardized section and i would like to implement DPL on it.

== Parser versus Hook change? ==

Does anyone know what might have changed in the code to cause the following statement to no longer include the category here, as seen below:

<code><nowiki>{{#dpl:category={{PAGENAME}}|category=Application Error|notcategory=Subtopic-topic|replaceintitle=/{{BASEPAGENAME}}\//,|format=,\n*,[[{{BASEPAGENAME}}/%TITLE%{{pipe}}%TITLE%]],|notnamespace=Category|noresultsheader=There are no symptom entries for this application.[[Category:Articles with no symptom entries]]}}</nowiki></code>

The odd thing is that it is actually working for one of my templates. I resolved the issue by converting to the <DPL> hook instead. Still, it seems strange that this suddenly stopped working. [[User:Thorncrag|Thorncrag]] 20:31, 18 August 2010 (UTC)
:And I have just discovered that my workaround will not suffice because using the hook causes replaceintitle to not function the same as when using the parser call instead. [[User:Thorncrag|Thorncrag]] 21:18, 18 August 2010 (UTC)
::Note, as said in the thread above this one, you can also use <nowiki>{{#tag:DPL</nowiki> to access the <DPL> tag as a parser function which should have the exact same behaviour as <DPL> (compared to <nowiki>{{#dpl:</nowiki> which has slightly different behaviour compared to <DPL>).

:I'm not sure what the number of 70760 is, however as far as i know they still play nicely together as long as the version of DPL is post [[rev:68812]].

It will certainly be less efficient for plain ole' category listings (but then again this is a very inefficient extension, so if you care about efficiently, I doubt you'd use it).

== DPL & Nested Templates? ==

I may be missing something so I am posting the question here. Can DPL query variables passed to a nested template? Meaning, ...
* You have a page named Resource1 which uses a template called ResourceType1 which is a member of the Asset Category.
* Within template ResourceType1 you pass variables to and call the template called AssetInfo.
* You then construct a DPL query which based on the Asset category queries all pages member of Asset and lists the variables found on the nested AssetInfo template

The rational for such a construct would be to list AsseInfo common to all resources which may use different ResourceType templates (type1, type2, etc) but are all members of Asset. Since the include/includepage line in DPL table output must be consistent, querying the nested common template seems the best approach but does not work.
please advise?, thanks ahead of time for replies [[Special:Contributions/208.79.244.111|208.79.244.111]] 23:23, 4 October 2010 (UTC)

== Replace in title breaks with titles that contain parentheses ==

I've just discovered that an article title which contains parentheses causes the replaceintitle statement to break in that it will no longer perform any longer. In context, I have a replaceintitle which is supposed to remove the BASEPAGENAME from the title or an article that is a subpage, so that when I output title I can output only the name of the subpage instead of the entire trail. I still need to do further troubleshooting to see if it is actually BASEPAGENAME or %TITLE% which is breaking. Nevertheless, it's clearly an issue with the extension.

:::<nowiki>{{#tag:DPL</nowiki> Should take the exact same syntax as <DPL>. If there's something that works for <DPL> but not <nowiki>{{#tag:DPL</nowiki>, that's probably a bug in mediawiki (core) not the extension, since converting <nowiki>{{#tag:DPL</nowiki> to <DPL> is part of the parser. (With that said, I'm not sure how it'd help you with your issue, since the two should be exactly the same with exception of parsing the args before passing to DPL.).

== Use with TreeAndMenu Extension ? ==

Hi,

I only need this:

{{#dpl:category=Foo|format=,**,[[%PAGE%]]\n,}}

..To dynamically add all pages to a tree that is created by the Extension TreeAndMenu.
I´ve tested it and it works great. Though I´m planning an opened wiki I´m a bit scared
about the red box on this extensions main page telling me that it has a major security
risk.

Is it possible to enable this extension only for a specific (admin) page or to eliminate
the security risk by adding some contraints?

Thanks in advance!

Hi again. Sadly that was not the solution. If the option to allow DPL only on protected pages is enabled this also affects the NavTree (Extension: TreeANDMenu) that needs DPL to work propperly. What I need is DPL to only work in the sidebar :-). But I don´t know if that is easily possible?

== Tree and Menu and DPL - Advanced use ==

I'm currently using Tree and Menu and DPL to generate lists as shown in the Example. Works fine.

{{#tree:id=ToolsMenuTree|openlevels=0|root=Tools, Tips and best practice|
* [[Tools and Tricks|Overview]] (Introduction Page)
{{#dpl:category=Tools and Tricks|format=,**,[[%PAGE%]]\n,}}
}}

The problem is that our wiki will have a lot of pages and subpages, making the list expand really fast with similar named entries such as:
Outlook
Outlook/Installation
Outlook/Usage

With the example structure above, is there a way to automatically create subfolders for all subpages using DPL syntax? Should be looking something like that
**Outlook
***Installation
***Usage
Any hints would be greatly appreciated. (Mike)

== Breaks when using ordermethod pagesel ==

I've run into an interesting problem. When attempting to generate a list using "linksfrom" and setting ordermethod to "pagesel", the parser breaks with the following error:
<pre>SELECT DISTINCT `page`.page_namespace as page_namespace,`page`.page_title as page_title,`page`.page_id as page_id, pagesrc.page_title as sel_title, pagesrc.page_namespace as sel_ns, CONCAT(pl.pl_namespace,pl.pl_title) AS sortkey FROM `pagelinks` as plf, `page`as pagesrc, `page` WHERE 1=1 AND `page`.page_is_redirect=0 AND `page`.page_namespace = plf.pl_namespace AND `page`.page_title = plf.pl_title AND pagesrc.page_id=plf.pl_from AND ((plf.pl_from=0)) ORDER BY sortkey ASC LIMIT 0, 500

Error message is:
Unknown column 'pl.pl_namespace' in 'field list' (localhost) </pre>
What's interesting is that this error does NOT occur if I change "linksfrom" to "linksto". What's also interesting is that on a cursory check of DPLMain.php for malformed code and found that the column pl.pl_namespace isn't even referenced in the "linksfrom" section, but is referenced in the "linksto" section, but I may not be looking at it right.

== Show images of a category including links to pages using these images! ==

Hi all,

I have a difficult question. I would like to create a gallery like that:

{{#dpl:
|category=Oneofmycats
|namespace=Image
|format=«gallery»,%PAGE%¦%NR%. %TITLE%\n,,«/gallery»
}}

That works great. But now I would like to have the name of the page (all of my images are at least only used on one page!) which makes use of the image as image text (not TITLE). In addition to that the name of the page should be a linkt to the page! So it would be possible to show all Images of a certain category including linkt to each page using this image (there is only one page!).

Found this code here:

{{#dpl:
|imageused=myimage.jpg
|format=,[[%PAGE%]]\n,,
}}

But I don´t know how to merge this two operations to one big thing!

Hope you understand what I mean :-).

Thanks in advance.

== DPL for category page – order by second name? ==

I'm using DPL for a personalized category page because I didn't like the MediaWiki-own view. Everything works fine but there is one point I despair of. For the category of persons I want the list to be ordered by second name. In the standard category view this issue is solved by a tag on every page that tells MediaWiki how to order, e.g. on the page "Angie Gielach" <nowiki>[[Kategorie:Personen|Gielach]]</nowiki> to have it listed under "G" instead of "A".

In DPL I use the following code to display the pages of my category "Personen" alphabetically:

<pre><nowiki>
===A===
<DPL>
category = Personen
format = ,\n* [[%PAGE%|%TITLE%]],,
title<=B
</DPL>
</nowiki></pre>

Has anyone a solution for this?

I'm running MW 1.16.2 with PHP 5.2.17 (cgi) and MySQL 5.0.91mm-log

Have I forgotten something? I put in the following on my localsettings.php and downloaded from the extension page the proper package for my version of MW. <pre> include("$IP/extensions/DynamicPageList/DynamicPageList2.php");</pre>

I don't know where else to go for help. I've reviewed bugs and issue pages and really didn't see anything applicable. I even tried to install the Wikimedia version of this extension and that worked fine (although that version doesn't have all the function I want so I'd rather have this one.) Please help. --[[User:Thing 1|Thing 1]] 23:44, 30 August 2011 (UTC)

== Question about "includematch" ==

I use this great extensions in two of mine wikis. In the last times, i have some problems with includematch.
My Wiki is about Final Fantasy XIV Online, for info ;)

NPCs are selling some Items, the item goes in the category:example sells from NPC.
Now, some NPCs sells example-head, examplefeed, example-earring. If i create now the Article examlpe,
i use this DPL:
<pre>
{{#dpl:
|category = {{SUBPAGENAME}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{fixapos|{{fixtick|{{fixparen|{{SUBPAGENAME}}}}}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

Here i use the _Template:Sellsrow to get the Price and the Template:NPC dpl Zones to get all other datas.
In the Template:Sellsrow, i define '''Item'''. Thats why my includematch say get where Item = <nowiki>{{SUBPAGENAME}}</nowiki>.
So, my Articles shows me now in the Table all sellinginformations about:
*example
*example-head
*examplefeed
*example-earring

i try'd some other includematch variations like this:
<pre>
{{#dpl:
|category = {{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

but at least, i have allways the Same problem. It shows me all what that NPC have, where example is in :\
The only what i want to see, is the Data for example >.< Someone knows how i can fix it? [[User:Yukii|Yukii]] 12:52, 17 October 2011 (UTC)

::I'm not quite sure I understood everything you said, so in case you want to clarify, you can tell me in German. // Ich bin mir nicht ganz sicher, dass ich alles richtig verstanden habe, und falls nicht, dann kannst du es gerne auf Deutsch nochmals erklären.
::The problem is, as far as I can see, that you never included the line "Item=..." in your DPL call; you only called to include "Price=..." parameter in the {Sellsrow} template. The includematch function works only, if you include the respective parameter, so in order for it to work, you need to change <code>{Sellsrow}:Price</code> to <code>{Sellsrow}:Item:Price</code>. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 13:43, 22 March 2012 (UTC)

== Warning about $maxResultCount ==

Just as a heads-up, <code>$maxResultCount</code> is '''not''' a limit on DPL's results, but a limit on the amount of rows pulled from the database. '''That is not the same thing'''. For example, the DPL query...

<DPL>
includematch=/\|\stemplate-attribute\s=\svalue/s
titlematch=Foo%
category=Foos
</DPL>

...will '''first pull all pages beginning with "<code>Foo</code>" in the category "<code>Foos</code>" from the database''', and only '''then''' check for the <code>includematch</code> pattern. In other words, if <code>$maxResultCount</code> is 500 and you have 800 <code>Foo%</code> pages in the <code>Foos</code> category, '''''even if just ten of those match your <code>includematch</code> pattern, you will probably not get all ten'''''.

Our solution was to remove the limit entirely (<code>$allowUnlimitedResults = true</code>), because our wiki is private and we have a strong control over authorship.

Your mileage may, of course, vary. -[[User:Pinkgothic|pinkgothic]] 13:32, 30 November 2011 (UTC)

== Null edits (or dummy edits) required for updating DPL listing ==

The wiki I administer makes a huge use of DPLs for constructing lists of pages and controlling workflows--very well might I add.

One problem that I have perennially run into however is the need to execute a null edit in order for pages to properly show up in a DPL when the DPL is grabbing based on, for instance, page category. What I don't understand is that when accessing the page in question the category is correct, but the DPL listing the page will not include the page in its list until executing a null edit on the page. I'm fairly knowledgebale about this extension but I have not come up with a solution to this problem. I've even tried using updaterules to "touch" the page when the list is built, but that feature does not seem to be usable at this point.

Since the page shows the correct category, and the job queue is empty, I can't actually figure out why this is happening. The only thing that I can think of is that the DPL is stored in a cache; however, that should not be causing this since cached results are supposed to be disabled by default. I do have MediaWiki parser cache set to enabled as well as file cache, but disabling these seems to have no effect on the symptom. Any thoughts on this? [[User:Thorncrag|   Thorncrag  ]] 18:40, 12 January 2012 (UTC)

:I may have posted too soon; I ''completely'' disabled caching across the wiki and this seems to have resolved the problem altogether. This works for now, although from a scalability perspective I'm not sure. [[User:Thorncrag|   Thorncrag  ]] 19:20, 12 January 2012 (UTC)

::I think I posted too soon again. I think disabling cache only caused an update, but null edits are still required. I can't seem to find a way around this. [[User:Thorncrag|   Thorncrag  ]] 16:39, 1 February 2012 (UTC)

== "skipthispage" - not bolded when created by DPL ==

Hi! I'm working through the book MediaWiki and Beyond. Great book, but I've run into something that doesn't seem to be working. In the book it says that if you use the 'skipthispage' variable and set it to false, not only will the page you are on show up in your list (in this case a navigation list), but since its pointing to itself, it will default to bolded text rather than a link. I don't seem to be able to get that behavior though. If I put a link to the page within itself, that will bold and present just as text, but not when it comes through the dpl command. Any ideas why? Thanks! [[User:Ncarty97|Ncarty97]] 20:41, 1 February 2012 (UTC)

== DynamicPageList only works with global $wgRawHtml set to true. ==

Between MediaWiki version 1.15 and 1.16 the way the < html > tag is handled changed. As a result, the DynamicPageList extension's abuse of the global $wgRawHtml setting to temporarily enable raw HTML content is broken. The normal way (to my knowledge) for an extension developer to embed raw HTML is to create one or more markers and then to post process the content and replace the markers with HTML after MediaWiki has done all of it's HTML stripping.

== Attempting to use DPL to create a table "on-the-fly" on any given article page by pulling from a list on a page; Getting error message: %DPL-1.7.6-WARNING: No results! ==
* Hi, so my goal in this scenario is to create a table on-the-fly using DPL and put that table on any given article page (I've opted to do a template call to facilitate this) -- and so part of the problem has been to figure out which of the DPL commands are best suited to accomplish this. I started with table and tablerow and initially got the results I was looking for on simpler test examples. But now I'm getting this error %DPL-1.7.6-WARNING: No results! and I can't find my bug! So yesterday I started looking at the secseparators and multisecseparators commands, but the syntax is killing me and they're just a bit too tricky for me right now (I just started learning/implementing DPL). In the DPL Manual it even suggests sticking with "table" and "tablerow", and that's what I'd like to do.
* I'd be grateful for some help figuring out where I took a wrong turn.
* One thing I saw yesterday was that I had misnamed the first parameter - i.e., Drug Code instead of Pfizer Drug Code. So I corrected that. It still didn't work. So I created a new Template:Drug Info 5 and Template:Drug Info5.dpl - suspecting that maybe there was something I wasn't aware of in the functioning of a phantom template where even if I fixed the parameter name in the dpl template, the phantom template might not pass the parameters through properly (?).
* Further down I list an example that did work. That's the one I built upon to try to get this one to work.
* Many thanks for your reply and insight. Cheers, Jeff Western cell: 323.449.7944

::I'm currently trying to figure out how to use the output of this table to enable the end-user to pick a drug (a row of Drug Info data) and copy that row and only that row to a new table in another section of the same page.

::I appreciate your having looked at my questions, in any case. Thank you!
:::You could upload files via [[Special:Upload]], but I recommend uploading to an image hoster like http://tinypic.com or something similar.
:::I am still a bit unsure what you mean with copying that code to the same page. Are you trying to create a table, or code for a table that can be copied and pasted?
:::The tablerow in the latest statement shouldn't do anything as the entire output of a phantom template should not be changed by tablerow.
:::The linksto statement is selecting pages basically the same way as the "what links here"-tool.
:::The way you use the titlematch statement should only give you one page, the very one you put into the statement. If you want to select several pages with titematch, you will have to use "_" as a one letter wildcard or "%" as a wildcard for any amount of letters; for example "titlematch=c_t" would give you "cat", "cut", et.al. yet "c%t" could even give you "cannot", "carrot", ...

::Theaitetos, I much appreciate your looking at this and answering with this code. I just tried it and it works. I got my code with the phantom template to work as well, but yours is a bit cleaner of course. I do get some multiple hits on a couple of the drugs, not sure why, but I suspect it might be my error somewhere (maybe too many category tags?!); I also got multiple hits with my code.
::(7/12/12)'''''On another note, the last piece of the puzzle for this first User Story that I'm trying to solve right now is this...''''' '''Once the user is on a Disease page, how do I "automate" (from the user's pov) the selection of drug(s) that they wish to associate with the disease?''' (...which then leads to the creation of the on-the-fly-dpl-table, which is pretty much working now -- thanks again!) So, I've checked with the internal IT dept here, and Javascript drop-menus are out of the question -- too bad, seems that's the nicest way to implement this. Raw HTML is not allowed currently on the company's internal wiki (and discouraged in general), and Javascript is only allowed by changing Common.js – which is a javascript which is triggered on every page load on the wiki. So they're telling me it's very inefficient to include Javascript on their internal wiki. Okay, so the approach I just hit on yesterday (brainstorming in my head while smoking a cigar!) is to do the following:
* Created a template: <nowiki>{{DPL for EQDD Diseases List with include redirects}}</nowiki>
* This template has DPL: <nowiki>{{#dpl: |category=EQDD Diseases List |mode=none |redirects=include |format=,\n* EQDD for [[%PAGE%|%TITLE%]],, }}</nowiki>
* Then I do the template call on any Disease page where I need it and it works, producing:
:::EQDD for Age Related Macular Degeneration
:::EQDD for Allergy and Respiratory
:::EQDD for Asthma
:::EQDD for Bunionectomy
:::EQDD for Chronic Abacterial Prostatitis
:::EQDD for Crohn's Disease
:::EQDD for Crohn’s Disease
:::EQDD for Dental Pain
:::EQDD for Discoid Lupus
:::EQDD for Endometriosis
:::EQDD for Inflammation
:::EQDD for Lupus
:::EQDD for Lupus Nephritis
:::EQDD for Male Erectile Dysfunction (MED)
:::EQDD for Ophthalmology
:::EQDD for Pain
:::EQDD for Primary Dysmenorrhea
:::EQDD for Systemic Lupus Erythamatosus (SLE)
:::EQDD for Ulcerative Colitis
:::EQDD for Women's Health and Urology
*'''But here's is where I run into a stumbling block...''' '''''I've discovered that when I try to run the subst: command on dpl, I just can't get it to substitute the straight text for me, e.g., <nowiki>{{subst:{{DPL for EQDD Diseases List with include redirects}} }}</nowiki>. What it does is always gives me the dpl in the substitution. What I need''' '''''I think!''''' '''is the straight text so that I can manipulate it. Because clearly, one cannot manipulate the output from a template call, or DPL, as it is just for viewing, right. So unless there is a way, using DPL commands, to further manipulate the data (on-the-fly by the DPL) such that a user can somehow select one of the diseases (list above) -- then I don't see any other way to do this. I suppose they could just highlight the text in the page name (from the list above), copy it, and paste it into a link on that Drug page, e.g., <nowiki>[[EQDD for Ulcerative Colitis]]</nowiki>
*''''' You see, what I'm trying to do is a work-around to not having a drop-down menu option for folks to be able to select from a list of already existing Disease pages. This way, they cannot possibly enter the name of the Disease page incorrectly. So what I'm trying to do is figure out a way to take a Disease page name (exactly as you see them listed above) and turn that page name into a <nowiki>[[link]]</nowiki> on the drug page -- thus the association between the drug and the disease. Then I use the linksto= command, and I get a listing of just the drugs that have been selected and associated with a disease, displayed by the on-the-fly-dpl-table on the Disease page. Again, any suggestions would be greatly appreciated. Thank you.

:*As far as javascript is concerned: There should be some javascripts coded into the core Mediawiki css anyway, so you could try to use that stuff to do some drop-down menus. For example, try to see if the following table works in your wiki:
::* Thank you for this great suggestion! This would be a terrific solution but unfortunately it doesn't run on the company's internal wiki. I'm thinking they don't have any Javascript enabled..? When I put this table into the internal wiki, it builds a table just fine, but it's not interactive (won't expand, collapse) like it does here.

:*As for the substitution: You have to substitute a dpl-call by adding the "subst:" into the dpl-call, i.e.: <code><nowiki>{{subst:#dpl:</nowiki></code>
::* That's ''AWESOME!'' Thank you -- just tried it and it works great! You see, what I'm after is implementing a User Story where the goal is associate a drug with a disease and in order to do this, I must ensure the end-user cannot enter a link incorrectly... ergo my interest in drop-down menus! Shame they won't work on this company's wiki. Anyway, so my work-around is to grab all the disease pages (they're tagged by Category of course) and then wrap <code>[[..]]</code> square brackets around the disease page name (article name) and then instruct the end-user to copy that text exactly (with the brackets) and paste it into the Drug page. So that creates the link, which <code>linksto=</code> then uses to pull up only those Drug pages that have been ''associated'' with a particular Disease page. Of course down the road, it would be nicer to have that <code><nowiki>[[link]]</nowiki></code> get inserted in a more automated fashion -- to avoid any possibility of the user making a mistake.
:*It's hard to imagine what output you specifically desire without looking at it. Could you put one example down here, so I can see it? I.e. the direct output you desire, no dpl anything, just how you want it to look like and I'll see if I can find the proper code to produce said output.
::*Yes, I can appreciate that. That's why I wear multiple hats on this job - Business Analyst, to understand their needs and document requirements - Developer, to implement the User Stories - and PM to hopefully make all this happen in time. So next week I'm going to set about updating my User Story diagrams and I'll start with this user story, and I'll list it here for you to see. Again, many many thanks for your great suggestions. It's been a hard week -- what with going down blind alleys with subst: -- and your hint will I think get me there!
:*About having multiple results: You can disable multiple results by adding the parameter <code><nowiki>distinct = strict</nowiki></code> to your dpl call.

== php Strict Standards error, MediaWiki 1.19.1 installed on xampp 1.8.0 ==

I recently installed MediaWiki 1.19.1 on xampp 1.8.0. Yesterday I added this extension and while the pages that call it do produce a list of pages very nicely, there is also an error:

Strict Standards: Only variables should be assigned by reference in D:\xampp\htdocs\mediawiki\extensions\DynamicPageList\DPLMain.php on line 2549

I am no php mediawiki or apache hotshot, but after searching it seemed likely that the issue was overzelaous error reporting by php.

In php.ini I changed

error_reporting = E_ALL | E_STRICT

to

error_reporting = E_ALL

and restarted apache. Then I completely rem'd that line. But the error message persists. Any suggestions?

:Depending on your caching settings, the error could have been cached from before you changed the error reporting levels. Try Purging the page where the error happens.

:''This is a third-party extension, not to be confused with the [[Extension:DynamicPageList (Wikimedia)|DynamicPageList used on Wikimedia sites]].''

 

'''DynamicPageList''' (DPL) is a reporting tool for MediaWiki, listing category members and intersections with various formats and details. For full documentation, see the [http://semeb.com/dpldemo/DPL:Manual manual] (German Manual [http://www.wiki-aventurica.de/wiki/Hilfe:Dynamic_Page_List Hilfe:DynamicPageList]).

In its most basic form, DPL displays a list of pages in one or more categories. Selections may also be based on factors such as author, namespace, date, name pattern, usage of templates or references to other articles. Output takes a variety of forms, some of which incorporate elements of selected articles.

This extension is invoked with the parser function <code>{{#dpl: .... }}</code> or parser tag <code><DPL></code>. A [[Extension:DynamicPageList (Wikimedia)|Wikimedia]]-compatible implementation of certain features can be invoked with <code><DynamicPageList></code>.

DPL can result in computationally-expensive database queries. For best performance, use the optional parameters [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#allowcachedresults allowcachedresults] and/or [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] where possible.

== Installation ==
The extended dynamic page list (DPL) is now in Wikimedia's SVN (currently revision 2.0, soon 2.01). To install:
* download the extension files for your version of MediaWiki, and place them in the <code>extensions/DynamicPageList</code> directory
* add <code>include("$IP/extensions/DynamicPageList/DynamicPageList2.php");</code> to LocalSettings.php
* set overrides for DPL configuration variables, if desired
LocalSettings.php must '''not''' include [[Extension:Intersection|Wikimedia's version of DPL]] (Intersection). If you want to run them in parallel, [http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/DynamicPageList/DynamicPageListMigration.php?view=markup include DynamicPageListMigration.php instead] to prevent this extension from overriding <code><DynamicPageList></code>.
===Configuration===

DPL configuration settings and their default values, '''[http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_Source_and_Installation#Server-Wide_Configuration:_Extension_options from the manual]''':
::{|
|<code>ExtDynamicPageList::$maxCategoryCount</code> || ''?''
|----
|<code>ExtDynamicPageList::$allowUnlimitedCategories</code> || ''?''
|----
|<code>ExtDynamicPageList::$minCategoryCount</code> || ''?''
|----
|<code>ExtDynamicPageList::$maxResultCount</code> || 500
|----
|<code>ExtDynamicPageList::$allowUnlimitedResults</code> || <code>false</code>
|----
|<code>ExtDynamicPageList::$categoryStyleListCutoff</code> || ''?''
|----
|<code>ExtDynamicPageList::$respectParserCache</code> || <code>false</code> for <dpl> but <code>true</code> for <DynamicPageList>. If set to 'true' DPL will no longer behave dynamically because its output is taken from the ParserCache.
|----
|<code>ExtDynamicPageList::$options</code> || ''no options''
|----
|<code>ExtDynamicPageList::setFunctionalRichness($level)</code> || 4 ''''
|-
|colspan=2|
|}
The global variable {{manual|$wgNonincludableNamespaces}} is also respected by DPL. It will prevent the contents of the listed namespaces from appearing in DPL's output.

'''Note: <code>$maxResultCount</code> is a LIMIT ''on the SQL query itself''. Some DPL query parameters like <code>includematch</code> are applied ''after'' the SQL query, however, so results here may easily be misleading.'''

==== Functional richness ====

DynamicPageList has many features; some are expensive, or dangerous in the wrong hands. It is important to choose an appropriate level of functionality for your wiki.

* <code>ExtDynamicPageList::setFunctionalRichness(0)</code> is equivalent to Wikimedia's DPL
* <code>ExtDynamicPageList::setFunctionalRichness(1)</code> adds additional formatting parameters
* <code>ExtDynamicPageList::setFunctionalRichness(2)</code> adds performance equivalent features for templates and pagelinks
* <code>ExtDynamicPageList::setFunctionalRichness(3)</code> allows more-expensive page inclusion features and regular expression queries; expect to use the [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] parameter
* <code>ExtDynamicPageList::setFunctionalRichness(4)</code> permits exotic and potentially dangerous batch update and delete operations; not recommended for public websites

'''Note: The Functional Richness grouping described above is a built-in suggestion; it can easily be adapted to your own preferences within "DPLSetup.php".'''

==Use==
===Extended DPL functionality===
Extended DPL is invoked by using the parser function <code>{{#dpl: .... }}</code>, or the parser extension tag <code><DPL> .... </DPL></code>.

:''See: [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_General_Usage_and_Invocation_Syntax Manual - General Usage and Invocation Syntax] and [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Criteria_for_page_selection Manual - '''DPL parameters''']''

=== Backwards-compatible functionality ===
Functionality compatible with Wikimedia's DPL extension can be invoked with <code><DynamicPageList> .... </DynamicPageList></code>.
:''See: [[Extension:DynamicPageList (Wikimedia)#Use]]''

==Overview==
Assume you have written some articles about ''countries''. Typically these articles will have three things in common:
* They will belong to a common category
* They will have a similar chapter structure, i.e. they will contain paragraphs named 'Religion' or 'History'
* They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

===DPL generates reports on articles===
Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on the countries.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

With DPL you can ..

* generate a list of all those articles (or a random sample)
* show metadata of the articles (popularity, date of last update, ..)
* show one or more chapters of the articles ('transclude' content)
* show parameter values which are passed to the common template
* order articles appropriately
* present the result in a sortable table (e.g.)
* use multi column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* select by a logical combination (AND,OR,NOT) of categories
* specify a range for the number of categories the article must be assigned to
* select by a logical combination (AND,OR,NOT) of namespaces
* define a pattern which must match the article´s name
* name a page to which the article must or must not refer
* name a template which the article must or must not use
* name a text pattern which must occur within external links from a page
* exclude or include redirections
* restrict your search to stable pages or quality pages ("flagged revisions")
* use other criteria for selection like author, date of last change etc.
* define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* name
* date of last change
* popularity
* user who changed them last
* size
* restrict the output to the first n articles or to a random sample
* use descending or ascending sequence

'''Define attributes you want to see'''
* article name
* article namespace
* article size
* date of last change
* date of last access
* user who changed them last

'''Define contents you want to show'''
* whole article
* contents of certain chapters (identified by headings)
* text portions (defined by special marker tags in the article)
* values of template calls
* substitute the original template by a different one and show the output of that template

'''Define the output format'''
* specify headline and footer for your report
* use ordered list, unordered list
* use tables, sorted tables (using javascript)
* format table fields individually by applying templates to their content
* use category style listing
* create "tag clouds" by varying output text size depending on popularity of pages
* multi column output
* truncate title or contents to a certain maximum length
* add a link to the article or to one or more of its chapters

===DPL generates reports on categories===
Apart from producing a list of pages which match certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

===DPL can be used for bulk editing===
Sometimes you want to perform a similar editing task on many articles (like adding a template at the beginning of the text). DPL has a feature which allows you to update other articles based on regular expressions. This feature is experimental and can be disabled in the DPL config file.

===DPL extracts objects and relations for generation of graphs with [[Extension:Wgraph]]===
With DPL you can generate output which is then fed into other MediaWiki extensions. An especially useful application of this kind is graph generation. DPL can analyze your wiki and prepare output which is then used by [[Extension:Wgraph]] to visualize it.

===DPL interacts with other extensions===
There is a special mechanism which allows you to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can generate nice bar graphs or pie charts using DPL together with ''Ploticus'', you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a light-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

===DPL and performance===
With a few lines of DPL code it is possible to create huge output and CPU load (think of a DPL query which tries to include the contents of all articles in your mediawiki ;-)). Normally this is not a problem because users who write DPL queries have some level of expertise. If you are afraid, however, you can restrict the execution of DPL queries to ''protected articles''.

Apart from that the general performance of DPL on medium-size wikis is quite acceptable (see the performance tests on the dpldemo website). Use of [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#allowcachedresults allowcachedresults] and/or [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] where possible can improve performance.

==See also==
===Further reading===
DPL can do much more than we can explain here. A complete '''[http://semeb.com/dpldemo/DPL:Manual manual]''' and many examples can be found on the on the separate [http://semeb.com/dpldemo DPL website].

===''Call'' extension===
The website where DPL is offered for download also contains the ''Call'' extension which allows to call an arbitrary MediaWiki article from the command line or from a wiki link and pass parameters to that article at the same time.

===Other applications===
* [[DPL Page Name S/N Maker]]-Use this extension to create pages with serial number page names

=== Comparisons ===
* [[Comparison of Dynamic Pagelist x Semantic Mediawiki]]

===Related extensions===
* [[Extension:BackLinksFunctions|BackLinksFunctions]] counts backlinks
* [[Extension:News|News]] creates reports on page changes
* [[Semantic MediaWiki]] turns links and data in wiki pages into queryable information
* [[Extension:TemplateTable|TemplateTable]] creates tables from template fields
* [[Extension:Ploticus|Ploticus]] can be used to create charts from DPL query results
* [[Extension:Wgraph|Wgraph]] creates graphs from DPL output
* [[Extension:Todo Tasks]] creates/maintains todo tasks and notifies users to whom the task is assigned
* [[Extension:DPL Calendar]] a highly configurable calendar
* [[Extension:CategoryLink]] Creates a table of the wiki's categories

===Older versions of this extension===
* [[Extension:DynamicPageList2]] (older version)
* [[Extension:DynamicPageList (Wikimedia)]] (the one used on Wikinews and Wikibooks. Note this extension is a fork of the other extension, and not exactly an older version)

:I contacted you about the developers' days/hackathon because my searches showed that you're a MediaWiki power user and that you might be interested in participating, and because I suspect you of being in North America (I could be wrong).

== JavaScript code review * invitation by Sumana ==

Thank you for
[//de.wikipedia.org/w/index.php?title=Benutzer_Diskussion%3APerfektesChaos&action=historysubmit&diff=95701939&oldid=94900086 your kind offer].

In 2011, I'm rather involved in projects of both real life and Wikis.

Recovering from New Year's Eve party in 2012 I do volunteer to pay attention to [[Special:Code/MediaWiki]] and I already read the [[Code review guide]].

In my experience somebody on code review does something like a formal approval of his colleagues work; is there any membership or formal registration to do?

Greetings, [[User:PerfektesChaos|PerfektesChaos]] 17:21, 9 November 2011 (UTC)
:PerfektesChaos, thanks for your offer! I hope you are enjoying the code review guide, which has recently been rewritten.
:As long as you have a mediawiki.org login, you can do nonbinding code review. Since you do not yet have the formal status of code reviewer, you would provide comments and feedback along with the "inspected" and "tested" checkboxes and use the "signoff" button. If you do that for a little while and then ask for coder & code reviewer status, you'll then be given the privilege of being able to change a revision's status from "new" to "ok," "FIXME", "deferred" and so on.
:I hope that helps, and I hope you'll be interested in helping review some of our JavaScript code! Thank you! [[User:Sumanah|Sumana Harihareswara, Wikimedia Foundation Volunteer Development Coordinator]] 02:08, 10 January 2012 (UTC)

== Resources for non-WMF extension developers? ==

I've noticed there is a wealth of resources and support for core developers and for extensions being submitted for deployment on WMF wikis, but not as much for folks running independent wikis or developing extensions for non-WMF wikis. I was curious if that was a common perception, if there are resources I may be missing, if there are any plans in the works I could assist with or help motivate along. :) For example, it would be great if there was a similar review process for extensions not seeking deployment on WMF wikis, some sort of system for folks with commit access to maybe access test installations of the most recent versions of MW to provide more accurate compatibility information, more resources specific to the diversity of installations developers may face, etc. Just a thought - thanks! [[User:Varnent|Varnent]] 05:10, 26 November 2011 (UTC)

== Thank you ==

Thank you Sumanah!

A local wiki methinks appropriate for the teachers work. It seems very useful for students' writing reports, contributions, and even projects. The wikipedia is simply too big. But, the job of installing the local wiki wasn't as easy as it looks like.

I already have installed [[Manual:Math]] on my pages (see [http://www.elemenat.com/cyr/wiki/index.php?title=%D0%9C%D0%B0%D1%82%D0%B5%D0%BC%D0%B0%D1%82%D0%B8%D1%87%D0%BA%D0%B0_%D1%82%D0%B5%D0%BE%D1%80%D0%B8%D1%98%D0%B0_%D0%B8%D0%BD%D1%84%D0%BE%D1%80%D0%BC%D0%B0%D1%86%D0%B8%D1%98%D0%B5 Math Theory of Information] in Serbian), with many difficulties. Now, I'm working with the other Extensions (is it something's wrong with [[Extension:JsMath]]?), and again with many difficulties. Sorry, for not being in form for this job.

Have you some simple instruction for installing the Wiki Extensions?

Best regards,

[[User:Elemenat|Elemenat]] 15:33, 7 January 2012 (UTC)
:Elemenat, thank you for writing to me.
:I see that the JsMath extension is in beta, so yes, probably some things are wrong with it. It isn't ready for a polished release yet.
:I suggest you look at [[Extensions#Installing_an_extension]] for help.

== Berlin hackathon ==

Hello Sumana ji, Thanks for the invitation. I really want to attend, but I don't think I can go to Berlin and I have no knowledge. I just copy templates and gadgets to Odia Wiki and modify a bit according to the requirements. I really appreciate your works you have been doing for the MediaWiki developments. Thank You!

:ansuman, thank you for your reply.
:If you believe that you are not technically skilled enough to find the event useful, then I understand and won't push you to register and attend. :-) But please spend some time using our online learning resources, get as far as you can that way, and then apply for a seat again next year.
:I understand that developers in your area don't yet have a critical mass of experienced Wikimedia technology experts. So I suggest that your community should hold some in-person trainings using the documentation that already exists:

== Installing Git review on windows ==

I've just had a conversation with Roan about this at #mediawiki on IRC. According to the information he so helpfully provided, there's no workaround to installing git-review; since not having it will greatly lengthen git commands. This leaves the part where one has to install git-review. However, I was wondering if it would be possible to do that without having to install pip and then modifying the system PATH (that's the most annoying part of the process). http://pypi.python.org/pypi/git-review reads ''For installation from source simply add git-review to your $PATH''

However, I don't really know what $PATH is here.

Roan says that even if this method was successful, bypassing pip could mean that some dependencies of git-review may not get installed; resulting in a broken git-review (depending on the python version).

Here's what I think:

Installing pip and then installing git-review through python requires running python commands in cmd and modifying the system PATH manually. If the $PATH being referred to here is in fact the system PATH, this installation could mean:
* right click, save link as, unzip, paste in so-and-so folder
* Modify system PATH

If we have to go about messing with PATH no matter we download pip or not, why bother with one extra download? Just seems a waste of time.

Also, installing pip is annoying. [[Git/Workflow#Windows]] gives the order as install pip first and then install the setuptools .exe while http://www.pip-installer.org/en/latest/installing.html#prerequisites says that setuptools is a prerequisite for installing pip.

It would be nice if installation of git-review could be made simpler. Since I'm a noob and have already spent a lot of time in the first install, I daren't try to test the above hypothesis (installing git-review without pip). Maybe you know an experienced user who'd give it a shot? Thanks [[User:Siddhartha Ghai|Siddhartha Ghai]] ([[User talk:Siddhartha Ghai|talk]]) 02:35, 24 April 2012 (UTC)
:Siddhartha Ghai, thanks for talking with Roan and writing up that summary of the issue. I suggest you send it to wikitech-l to see whether there's an experienced user who can boot up a VM and try out your hypothesis!

Hi Sumanah, My name is Adethya from Chennai, Tamil Nadu, India.

Please forgive me for editing your user page. I am not good at editing. So I might slip on a few ethics of editing. But the reason I wanted to edit this page, is to let you know that I wanna participate in Berlin Hackathon, 2012. I have no idea about how things work at a Hackathon, but I am deeply interested in getting involved. please let me know if there is still room for scholarships which I will be glad to use for the Hackathon.

== My "note from foswiki" ==

Thanks for curating my [[Talk:Lua_scripting#Note_from_Foswikinote| about MongoDB!]]

But I was responding to a comment on the original [[User:Sumanah/Lua_vs_Javascript]] where I wrote that note, so I feel you've moved it somewhere less useful perhaps?

I was (perhaps clumsily) trying to counter the comment which implied that spidermonkey/V8 could not control their footprint programmatically. Of course, I might be wrong, given that I only have a cursory familiarity with MongoDB internals, and even less knoledge of MW's Lua/JS efforts.

But I am watching developments here with interest. [[User:Csirac2|Csirac2]] ([[User talk:Csirac2|talk]]) 02:54, 26 May 2012 (UTC)

== Gerrit project administrator ==

Hi Sumana,

As per [[Talk:Git/Workflow#x.5Bremote_rejected.5D_.28.22branch_not_found.22.29_16290|discussion]], Snaper said ''...So forget about "branching gets much easier" part as far as Gerrit is concerned Gerrit project administrator can create Gerrit branches in the repository. ...'' I could not find any notion of a Gerrit project administrator on the Git page, so it would be helpful to know who is a Gerrit project administrator and how to get in contact with them.

On a further note maybe it should be considered to make branching easier for anything that is not mw.core since extensions don't really have to rely on whatever policy is necessary to keep mw.core afloat. Thanks [[User:MWJames|MWJames]] ([[User talk:MWJames|talk]]) 11:38, 18 June 2012 (UTC)
:MWJames, thanks for your note. I don't control the branching policy, so do you mind if I move this discussion to the Git talk page? Also, you may find [[Git/Gerrit project ownership]] and https://gerrit.wikimedia.org/r/#/admin/groups/ useful.

Hello Sumana!!

Thanks for granting lab access to me that fast!! You used "Drtrigon" in order to create my account, this results for me in having 3 different nicks now. We should use either "drtrigon" for lower-case only and "DrTrigon" (with capital "T") else. Is it possible to rename (or if simpler delete and re-create) my account? That would be nice.

== SVN access for DPL maintenance ==

Hello Sumanah,
I am the author of DPL (third party). Two years ago I published a stable release which somebody put into the SVN for me.
Recently I published DPL 2.0 (which solves some major issues that had been open for a long time)
and bawolff was so kind to check in the sources for me into SVN. I made my changes based on the last version which I had published (2 years ago).
Now some changes have to be re-merged which have been made to DPL in SVN in the meantime by various people.
Two years ago I had been applying for SVN access and finally it was granted. But by then I did not have time to spend any resources on
the DPL project so I never used the account and lost my account data. Can you help me to regain access (I can be reached via gero.scholz(at)gmx.de).

:''This is a third-party extension, not to be confused with the [[Extension:DynamicPageList (Wikimedia)|DynamicPageList used on Wikimedia sites]].''

 

'''DynamicPageList''' (DPL) is a reporting tool for MediaWiki, listing category members and intersections with various formats and details. For full documentation, see the [http://semeb.com/dpldemo/DPL:Manual manual] (German Manual [http://www.wiki-aventurica.de/wiki/Hilfe:Dynamic_Page_List Hilfe:DynamicPageList]).

In its most basic form, DPL displays a list of pages in one or more categories. Selections may also be based on factors such as author, namespace, date, name pattern, usage of templates or references to other articles. Output takes a variety of forms, some of which incorporate elements of selected articles.

This extension is invoked with the parser function <code>{{#dpl: .... }}</code> or parser tag <code><DPL></code>. A [[Extension:DynamicPageList (Wikimedia)|Wikimedia]]-compatible implementation of certain features can be invoked with <code><DynamicPageList></code>.

DPL can result in computationally-expensive database queries. For best performance, use the optional parameters [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#allowcachedresults allowcachedresults] and/or [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] where possible.

== Installation ==
The extended dynamic page list (DPL) is now in Wikimedia's SVN. To install:
* download the extension files for your version of MediaWiki, and place them in the <code>extensions/DynamicPageList</code> directory
* add <code>include("$IP/extensions/DynamicPageList/DynamicPageList2.php");</code> to LocalSettings.php
* set overrides for DPL configuration variables, if desired
LocalSettings.php must '''not''' include [[Extension:Intersection|Wikimedia's version of DPL]] (Intersection). If you want to run them in parallel, [http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/DynamicPageList/DynamicPageListMigration.php?view=markup include DynamicPageListMigration.php instead] to prevent this extension from overriding <code><DynamicPageList></code>.
===Configuration===

DPL configuration settings and their default values, '''[http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_Source_and_Installation#Server-Wide_Configuration:_Extension_options from the manual]''':
::{|
|<code>ExtDynamicPageList::$maxCategoryCount</code> || ''?''
|----
|<code>ExtDynamicPageList::$allowUnlimitedCategories</code> || ''?''
|----
|<code>ExtDynamicPageList::$minCategoryCount</code> || ''?''
|----
|<code>ExtDynamicPageList::$maxResultCount</code> || 500
|----
|<code>ExtDynamicPageList::$allowUnlimitedResults</code> || <code>false</code>
|----
|<code>ExtDynamicPageList::$categoryStyleListCutoff</code> || ''?''
|----
|<code>ExtDynamicPageList::$respectParserCache</code> || <code>false</code> for <dpl> but <code>true</code> for <DynamicPageList>. If set to 'true' DPL will no longer behave dynamically because its output is taken from the ParserCache.
|----
|<code>ExtDynamicPageList::$options</code> || ''no options''
|----
|<code>ExtDynamicPageList::setFunctionalRichness($level)</code> || 4 ''''
|-
|colspan=2|
|}
The global variable {{manual|$wgNonincludableNamespaces}} is also respected by DPL. It will prevent the contents of the listed namespaces from appearing in DPL's output.

'''Note: <code>$maxResultCount</code> is a LIMIT ''on the SQL query itself''. Some DPL query parameters like <code>includematch</code> are applied ''after'' the SQL query, however, so results here may easily be misleading.'''

==== Functional richness ====

DynamicPageList has many features; some are expensive, or dangerous in the wrong hands. It is important to choose an appropriate level of functionality for your wiki.

* <code>ExtDynamicPageList::setFunctionalRichness(0)</code> is equivalent to Wikimedia's DPL
* <code>ExtDynamicPageList::setFunctionalRichness(1)</code> adds additional formatting parameters
* <code>ExtDynamicPageList::setFunctionalRichness(2)</code> adds performance equivalent features for templates and pagelinks
* <code>ExtDynamicPageList::setFunctionalRichness(3)</code> allows more-expensive page inclusion features and regular expression queries; expect to use the [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] parameter
* <code>ExtDynamicPageList::setFunctionalRichness(4)</code> permits exotic and potentially dangerous batch update and delete operations; not recommended for public websites

'''Note: Functional Richness parameters have been removed in the latest versions of the extension. There is no function for setting functional richness in these versions.'''

==Use==
===Extended DPL functionality===
Extended DPL is invoked by using the parser function <code>{{#dpl: .... }}</code>, or the parser extension tag <code><DPL> .... </DPL></code>.

:''See: [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_General_Usage_and_Invocation_Syntax Manual - General Usage and Invocation Syntax] and [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Criteria_for_page_selection Manual - '''DPL parameters''']''

=== Backwards-compatible functionality ===
Functionality compatible with Wikimedia's DPL extension can be invoked with <code><DynamicPageList> .... </DynamicPageList></code>.
:''See: [[Extension:DynamicPageList (Wikimedia)#Use]]''

==Overview==
Assume you have written some articles about ''countries''. Typically these articles will have three things in common:
* They will belong to a common category
* They will have a similar chapter structure, i.e. they will contain paragraphs named 'Religion' or 'History'
* They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

===DPL generates reports on articles===
Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on the countries.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

With DPL you can ..

* generate a list of all those articles (or a random sample)
* show metadata of the articles (popularity, date of last update, ..)
* show one or more chapters of the articles ('transclude' content)
* show parameter values which are passed to the common template
* order articles appropriately
* present the result in a sortable table (e.g.)
* use multi column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* select by a logical combination (AND,OR,NOT) of categories
* specify a range for the number of categories the article must be assigned to
* select by a logical combination (AND,OR,NOT) of namespaces
* define a pattern which must match the article´s name
* name a page to which the article must or must not refer
* name a template which the article must or must not use
* name a text pattern which must occur within external links from a page
* exclude or include redirections
* restrict your search to stable pages or quality pages ("flagged revisions")
* use other criteria for selection like author, date of last change etc.
* define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* name
* date of last change
* popularity
* user who changed them last
* size
* restrict the output to the first n articles or to a random sample
* use descending or ascending sequence

'''Define attributes you want to see'''
* article name
* article namespace
* article size
* date of last change
* date of last access
* user who changed them last

'''Define contents you want to show'''
* whole article
* contents of certain chapters (identified by headings)
* text portions (defined by special marker tags in the article)
* values of template calls
* substitute the original template by a different one and show the output of that template

'''Define the output format'''
* specify headline and footer for your report
* use ordered list, unordered list
* use tables, sorted tables (using javascript)
* format table fields individually by applying templates to their content
* use category style listing
* create "tag clouds" by varying output text size depending on popularity of pages
* multi column output
* truncate title or contents to a certain maximum length
* add a link to the article or to one or more of its chapters

===DPL generates reports on categories===
Apart from producing a list of pages which match certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

===DPL can be used for bulk editing===
Sometimes you want to perform a similar editing task on many articles (like adding a template at the beginning of the text). DPL has a feature which allows you to update other articles based on regular expressions. This feature is experimental and can be disabled in the DPL config file.

===DPL extracts objects and relations for generation of graphs with [[Extension:Wgraph]]===
With DPL you can generate output which is then fed into other MediaWiki extensions. An especially useful application of this kind is graph generation. DPL can analyze your wiki and prepare output which is then used by [[Extension:Wgraph]] to visualize it.

===DPL interacts with other extensions===
There is a special mechanism which allows you to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can generate nice bar graphs or pie charts using DPL together with ''Ploticus'', you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a light-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

===DPL and performance===
With a few lines of DPL code it is possible to create huge output and CPU load (think of a DPL query which tries to include the contents of all articles in your mediawiki ;-)). Normally this is not a problem because users who write DPL queries have some level of expertise. If you are afraid, however, you can restrict the execution of DPL queries to ''protected articles''.

Apart from that the general performance of DPL on medium-size wikis is quite acceptable (see the performance tests on the dpldemo website). Use of [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#allowcachedresults allowcachedresults] and/or [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] where possible can improve performance.

==MediaWiki SVN Version of DPL2==
The instructions on this page were written for the code that is available from http://semeb.com/dpldemo/Download and is different than the version available in MediaWiki's SVN. Some of the differences include:
* There is not a <DynamicPageList> tag, just a DPL and section tag.
* There is no setFunctionalRichness() function.
* The main class is named ExtDynamicPageList2 and not ExtDynamicPageList.

==See also==
===Further reading===
DPL can do much more than we can explain here. A complete '''[http://semeb.com/dpldemo/DPL:Manual manual]''' and many examples can be found on the on the separate [http://semeb.com/dpldemo DPL website].

===''Call'' extension===
The website where DPL is offered for download also contains the ''Call'' extension which allows to call an arbitrary MediaWiki article from the command line or from a wiki link and pass parameters to that article at the same time.

== MediaWiki Version ==

This page says that DPL requires v. 1.7+ of MW, but [http://semeb.com/dpldemo/index.php?title=DPL:Installation the DPL wiki] says 1.8+. Would be worth changing to whichever one is correct! I tried to install with 1.7 and it didn't work, which was disappointing. --16 November 2007

== Conflict with RSSReader Extension ==

I've noted a conflict between the RSSReader Extension and DynamicPageList Extension when both are run on the same page. See [[Extension talk:RSS Reader#Conflict with DPL2 Extension|Comment on RSS_Reader Extension]] for details. Any idea why this might be?

==Labeled Transclusion Sections with DPL 1.6.9==
We just installed DPL 1.6.9 and noticed that our section transclusions are no longer working.

For example, we have

<dpl>

title=Article1

include=summary

</dpl>

And it used to work with the previous DPL version which displayed all text in the summary section but with DPL 1.6.9 nothing is being picked up. Any ideas? -alhui

== Catch a template parameter ==

I am looking for a way to use DPL to catch, not the title of a page, but the parameter of a template:

if a page calls the template '''<nowiki>{{Temp|param1|param2|param3}}</nowiki>''', how to catch the param3 in another page, with a query on the first parameter and the second ?

--[[User:Fxparlant|Fxparlant]] 13:08, 7 August 2008 (UTC)

:You can use phantom templates for that purpose. DPL will call the phantom template instead of the original one and pass all parameters to the phantom template in the same way as they were passed to the original template. And within the phantom template you can do whatever you like - which means that you can simply output the third parameter.

== Tweak to make DPL backward compatible with DynamicPageList2 <suppresserrors> parameter ==

I'm one of the admins at ChoralWiki (www.cpdl.org), a free Public Domain scores library, and we use [[Extension:DynamicPageList2|DynamicPageList2]] a lot in it with parameter <suppresserrors> set to 'true'. We were doing an upgrade test to the newest version of DynamicPageList and after the upgrade all our DPL queries started showing this warning:

%DPL-1.7.4-WARNING: Unknown parameter '$0' is ignored. Help: available parameters: suppresserrors.

After a quick research we realized that parameter <suppresserrors> is no longer supported by the new DPL versions. It would be a pain to edit all pages where it appears, so we decided to tweak the DPL code to recognize it and behave as expected. We made the changes below, tested it and it worked fine. So we decided to post it here in case someone else faces the same problem. All one needs to do is to add the following lines in red to file ''DinamicPageList2.php'':

line 682:

/**
* noresultsheader / footer is some wiki text which will be output (instead of a warning message)
* if the result set is empty; setting 'noresultsheader' to something like ' ' will suppress
* the warning about empty result set.
*/
'suppresserrors' => array('default' => 'false', 'true', 'no', 'yes', '0', '1', 'off', 'on'),
'noresultsheader' => array('default' => ''),
'noresultsfooter' => array('default' => ''),

line 1157:

$bSuppressErrors = self::argBoolean(self::$options['suppresserrors']['default']);
$sResultsHeader = self::$options['resultsheader']['default'];
$sResultsFooter = self::$options['resultsfooter']['default'];

line 2095:
case 'noresultsheader':
$sNoResultsHeader = $sArg;
break;
case 'suppresserrors':
if( in_array($sArg, self::$options['suppresserrors'])) {
$bSuppressErrors = self::argBoolean($sArg);
if( $bSuppressErrors )
$sNoResultsHeader = ' ';
}
else
$output .= $logger->msgWrongParam('suppresserrors', $sArg);
break;
case 'noresultsfooter':
$sNoResultsFooter = $sArg;
break;

After the change, if <suppresserrors=true> is used in the query and 0 pages are returned, it won't show any warning message; if <noresultsheader='text'> is also used, it will show the 'text' supplied. [[User:Capmo|Capmo]] 13:40, 18 September 2008 (UTC)

:Since release 1.7.5 <tt>suppresserrors</tt> is part of the official DPL distribution. [[User:Algorithmix|Algorithmix]] 09:20, 21 May 2009 (UTC)

== Index (List of index-terms) for a book ==
I am experienced in editing wikipedia-articles. Now I want to use mediawiki on my server to write a book (around 1.000 articles). I want to mark index-terms in articles and have one page with a sorted index.
The book will exist of 1.000 articles. So it is no problem to generate the article dynamicaly when I will open the index.
Is DPL the right extension to do the job?

How to mark the index-terms in articles?

: Regards, Jan

::Hello Jan, creating a permuted index is a challenge because DPL normally walks sequentially through all articles which match the selection criteria and collects the desired information (in your case template invocations). In your case one would have to store the collected data (using the ''arrays'' extension ), re-arrange the order and then produce the output in a final step. With less than 10 lines of code all this is possible:
::<center>see     ''' http://semeb.com/dpldemo/index.php?title=DPL_Example_017 ''' </center>
::I know SMW and think it is powerful for expert users. The idea of DPL is to use MW as it is without introducing new syntax for those users who ''write'' articles.

== Problems ==

Hi. I have a problem with labeled section transclusion, the ''section'' tags show up along with the transcluded text. This problem only showed up recently; the page was doing fine four months ago when I left it. When I came back a few days ago, no changes have been made to the articles but the DPL pages have broken formatting. It is a Wikia page and I asked the Wikia staff about it too, but they haven't recognized something from their end being the source of the problem either. So here's the problem. Instead of this:

http://img.photobucket.com/albums/v59/daarklord/ForumGraphics/DplWtf01.gif

I get this instead:

My wiki can be found [http://nilgiri.wikia.com/wiki/Nilgiri_Wiki here].
The formatting error can be seen [http://nilgiri.wikia.com/wiki/Neck_equipment(all) here].

Please help. Thank you.

==A Bug?==
I use DPL together with MediaWiki 1.14.0, SMW 1.4.2, DPL 1.7.9 If I follow a link, that is done by the Call-Extension, the CSS-File of SMW is not included. What can I do? The main problem: The field “smwsortkey” is not more hidden, because the style for it is not included. Christian Weiss 14:44, 27 May 2009 (GMT+2)

:Please give more details. I assume that the problem has nothing to do with DPL; this means that it also occurs if you use the Extension:Call from the browser's URL-line or within a normal document like this <nowiki>[[Special:Call/:Mypage,a=b]]</nowiki>. I don´t understand your remark about a "style". Are you talking about css? Can you reproduce the error on the [http://semeb.com/dpldemo dpldemo website]? It has DPL 1.7.9 and SMW 1.0 installed.

:::It's like you said: I call a Template by the Call-Extension, the DPL-Calendar ":Current events" for example. If it's included the normal Way in a Page, in the HTML-Source the "SMW_custom.css" and the "SMW_sorttable.js" are included. If the Template ist called by the "Call"-Extension those files are not included in the HTML-Source. A workaround ist to include those files in the Common.css and Common.js for Skins, so it is included everytime. For the SMW_sortable.js I get then 2x sortbuttons :-) I think, the Call-Extension ist part of your Pakage, so I write my Problem to you. Christian Weiss 10:06, 06 Jun 2009 (GMT+2)

== LoF ==

I sthe LoF ment to be set as global in LocalSettings? I'd prefer it as option per DPL call. So I want to use a complex DPL call I would set LoF = 3 or sth inside the call.

:Currently the Level of Functionality is a configurable option which is global for the whole use of DPL in a wiki. It is meant to be a "protection belt" against abuse.

== DPL Doesn't Work after MW Upgrade from 1.13 to 1.15.1 ==

Hi, I have a private wiki we use as a content Management system at work. I updated the wiki from MW.1.13 to MW.1.15.1, and suddenly DPL doesn't work. For example, I have a page for each of our main applications, with a supbage called 'Troubleshooting'. Below that are more subpages, one for each troubleshooting document. The '/Troubleshooting' subpage consists entirely of DPL to list the child subpages for a user to browse and jump to.

For example (changing the page names to protect proprietary information):

We have a set of pages like so:

* Main:Zazaza
* Main:Zazaza/Troubleshooting
* Main:Zazaza/Troubleshooting/Error 51 - File not Found
* Main:Zazaza/Troubleshooting/Can't Save Configurations
* Main:Zazaza/Troubleshooting/App Crashes if User Chews Bubble Gum

The top page, Main:Zazaza, describes the application and has a link to Main:Zazaza/Troubleshooting.

Main:Zazaza/Troubleshooting consists entirely of DPL code that will list the three 'troubleshooting' child subpages with links. This page's DPL Code is as follows:


<DPL> 
titlematch=Zazaza/Troubleshooting/% 
notnamespace=Image 
notnamespace=Image_talk 
notnamespace=Template 
notnamespace=Template_talk 
replaceintitle=/.......Troubleshooting./, 
</DPL>


Previously, the DPL worked, and a user browsing to the Zazaza/Troubleshooting page would see a list of clickable links:

Error 51 - File not Found
Can't Save Configurations
App Crashes if User Chews Bubble Gum

Now, since the 1.15.1 upgrade, all that shows up is the following:

Extension:DynamicPageList (DPL), version 1.8.6 : <dpl_log_1>

Before you ask, no, there is no log being generated or updated anywhere within my wiki home that provides me with a clue as to why DPL isn't working.

I confess to being confused because when I originally downloaded DPL in May or June 2008, this was during the time frame that "old DPL" was known as "Intersection" and 'this' DPL was just known as "DPL", and at the time there wasn't even a reference to the forked versions on the extension page. (I only came to learn all of this with my research this past week.) However, I have verified that I am using semeb.com's Dynamic Page List (was using v.1.6.9, now using v.1.8.6.) I downloaded v.1.8.6 earlier in the week from http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/DynamicPageList/, and I just re-obtained the files from the ZIP archive available at http://semeb.com/dpldemo/images/f/fe/Semeb_extensions.zip and redeployed them to be certain. The behavior is still the same as above.

Any help would be appreciated.

== Parsing Pipes ==

I have run into a little bit of a quandary which I am trying to solve. I am trying to create a template with a set of parameters that are passed from a dynamically created list from DPL. However, when using the pipe character in the formatting for DPL like this:
<pre>{{Hot_issues
|<DPL>category=Application
category=Hot_issues
format=,|,[[%TITLE%]],
notnamespace=Category
noresultsheader=Nothing found...</DPL>}}
</pre>
...the pipe character is not parsed by the templating system, I think because of the order in which things are processed... The result is all the articles listed like this: "|Article1|Article2", and so on, instead of passing each one as a template parameter. I have been trying, but I can't think of a way around this. Does anybody have any thoughts on this? --[[User:Bsmithme|Bsmithme]] 21:12, 18 July 2009 (UTC)
:I have tried using subst:Hot_issues but that had no effect. I've also tried creating a template with "|", but that didn't work either. I think I am approaching it wrong...--[[User:Bsmithme|Bsmithme]] 21:15, 18 July 2009 (UTC)

== RESOLVED: Fatal error ==

After upgrading my wiki to MW 1.15 I got the error message:
<pre>Fatal error: Unsupported operand types in /home/schlott/public_html/wiki/includes/parser/LinkHolderArray.php on line 33</pre>
and the extension stoped working.

The solution was inside the DynamicPageList/DPL.php with the following statement in Line 36:
<pre>
// cloning the parser in the following statement leads in some cases to a php error in MW 1.15
// You must apply the following patch to avoid this:
// add in LinkHoldersArray.php at the beginning of function 'merge' the following code lines:
// if (!isset($this->interwikis)) {
// $this->internals = array();
// $this->interwikis = array();
// $this->size = 0;
// $this->parent = $other->parent;
// }
</pre>

After adding the mentioned code lines to LinkHoldersArray.php the extension works just fine. -- Flaming Moe

== Comment on differing versions by [[User:Algorithmix|Algorithmix]] ==
* Note that the version running on Wikimedia sites was at some point in time renamed to [[Extension:Intersection]] to avoid confusion with the extension described here. But the documentation still was talking of "DynamicPageList" and the SVN path was not renamed.
* Recently 'Intersection' claimed back its ancient name and that is why you now find the documentation of 'Intersection' under 'Extension:DynamicPageList'.
* On the other hand the DPL extension described here was still named 'DynamicPageList' and new functions were added. At some point in time downward compatibility with the version running on Wikimedia sites was lost. The extension was renamed to 'DynamicPageList2' but the documentation was still talking of "DynamicPageList".
* Then another bunch of functionality was added and downward compatibility (with DPL2) was lost. The name of this version was changed back to DPL (which was thought to be 'free').

''All this has created much confusion. Read below for a suggestion on how to re-unite the different variants.''

This extension '''Dynamic Page List (DPL)''' has the same roots as [[Extension:Intersection]]. Until recently DPL was almost - but not exactly - downwards compatible with ''Intersection''. A lot of confusion comes from the fact that ''Intersection'' uses the tag <DynamicPageList> whereas '''Dynamic Page List (DPL)''' uses the tag <DPL>.

DPL offers functionality '''that goes far beyond''' ''Intersection''. Some of this functionality might be useful also on Wikimedia sites. But the problem is that inexperienced users or people with 'not-so-good-intentions' might write DPL statements which create significant database load.

A good solution - which also puts an end to all naming ambiguities of ''DynamicPageList, DPL, DPL2'' and ''Intersection'' looks like this:
# There should be only ONE extension.
# It should be called ''DynamicPageList'' (short name DPL).
# It should listen to the tags ''DynamicPageList'' and ''DPL'' for compatibility reasons.
# Its sources should be in the mediawiki SVN
# It should be strictly downward compatible with ''Intersection''.
# It should offer a configuration switch (let us call it LevelOfFunctionality = LoF) which lets the administrator of a wiki decide, how much functionality will be offered to the users:
#* LoF = 0 is exactly identical with ''Intersection'' as of today.
#* LoF = 1 offers additional features which do not affect performance (mainly related to output formatting)
#* LoF = 2 offers additional features which are on the same conceptual level as ''Intersection'' like selection of pages by use of templates or by pagelinks. As the underlying table structures in the mediawiki database design are very similar to categories the performance cost of theses features are comparable in magnitude with ''Intersection'''s current features
#* LoF = 3 offers additional features which are more cost-intensive, like e.g. content transclusion from pages that occur in the DPL result; we think that a dedicated DPL cache could allow to offer these features also on high traffic sites - but this still has to be proved
#* LoF = 4 offers a last group of features which are a somewhat exotic and could create trouble if used by ignorant people (batch updates and batch deletions based on DPL query results)

:My own thoughts on this: it's a good idea, but performance is a huge consideration. I suggest investigating ways to avoid loading DPL code unless it is required, particularly [[Manual:$wgAutoloadClasses|$wgAutoloadClasses]]. Right now APC shows that it is touching all the code on every page access, and that's a significant cost when you have a large number of pages being accessed.

== Trying to List Pages... ==
Trying to List Pages within a Namespace in Category Mode, Alphabatized on a non category page. Sounds ridiculous however this is the syntax that i am using:
<pre><dpl>
namespace=Article
shownamespace=false
mode=category
ordermethod=category,title
</dpl></pre>
What i am trying to do is show all pages in the article namespace on a page in category mode alphabetized by the page title rather then the namespace. Currently all pages are organized under "A" because the pages are named Article:Page Name. I want to eliminate or mask the Article so that they are organized by Page Name.

Kevindank AT Gmail.com

:Hmh, you aren't very clear.
:1) is there really a custom namespace called "Article"? Cos otherwise you mean Main: "namespace="
:But I guess I know what you mean. Like in [http://semeb.com/dpldemo/index.php?title=User:Subfader/Olli1/O7 this example] you don't want U headings but 0-Z... I dunno a solution :/ --[[User:Subfader|Subfader]] 21:17, 21 October 2009 (UTC)

===Workaround ===
If you apply a very small patch you can use
ordermethod=titlewithoutnamespace
to get the desired result:

find (near line 1860 in DPLMain.php in the latest version)
case 'titlewithoutnamespace':
and add the following line immediately after that line:
$sSqlSortkey = ", $sPageTable.page_title ".$sOrderCollation." as sortkey";

I will add this code line to the next release.
In fact, the patch will make the new behaviour the default (which is o.k., I think). Use <tt>ordermethod=title</tt> to switch to the old behaviour.

==DISPLAYTITLE and DYNAMIC PAGE LIST==
is it possible to tie this to DISPLAYTITLE to sort pages by their DisplayTitle?

==installation instruction problems==
Thanks for this powerful extension. In order to help others to use it, I want to report two problems I just had in following the installation instructions in the article.

The instructions say:
add include("$IP/extensions/DynamicPageList/DynamicPageList.php"); to LocalSettings.php
However, the actual file downloaded for v1.14 was named DynamicPageList2.php. This modification worked:
include("$IP/extensions/DynamicPageList/DynamicPageList2.php");

The second problem is probably due to my lack of familiarity with PHP. The instructions appear to say to add a function call in LocalSettings after the include() statement above to control the richness level, like this:
ExtDynamicPageList::setFunctionalRichness(3);
However, this caused a fatal error, so I commented it out. Should the call be like this?
DynamicPageList2::setFunctionalRichness(3);

== Having DPL Maintain #section Links ==

If the pages I'm building my DPL from have links like <tt><nowiki>[[#section|A Section]]</nowiki></tt>, is it possible to to have DPL maintain the url of the page with that specific section, rather than have it change it to the page that has the DPL on it? — [[User:Cosmotron|Cosmotron]] 18:56, 8 November 2009 (UTC)

== Template:DPL_Extension creation as potential redirect loop ==

There is a DPLSetup.php routine, commonSetup(), which attempts to create an <nowiki>{{Extension DPL}}</nowiki> template using the userid of the first user to visit the wiki after the extension is installed:

<source lang="php">
private static function commonSetup() {

if (!isset(self::$createdLinks)) {
self::$createdLinks=array(
'resetLinks'=> false, 'resetTemplates' => false,
'resetCategories' => false, 'resetImages' => false, 'resetdone' => false , 'elimdone' => false );
}

// make sure page "Template:Extension DPL" exists
$title = Title::newFromText('Template:Extension DPL');
global $wgUser;
if (!$title->exists() && $wgUser->isAllowed('edit')) {
$article = new Article($title);
$article->doEdit( "<noinclude>This page was automatically created. It serves as an anchor page for ".
"all '''[[Special:WhatLinksHere/Template:Extension_DPL|invocations]]''' ".
"of [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)].</noinclude>",
$title, EDIT_NEW | EDIT_FORCE_BOT );
die(header('Location: '.Title::newFromText('Template:Extension DPL')->getFullURL()));
}

}
</source>

Two issues with this:
* (minor) The external link [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)] points to a disambiguation page here instead of to the actual extension info.
* (not so minor) If creation of the template fails, the user is redirected to [[Template:Extension DPL]] regardless, and the failed attempt to create the template is repeated until the browser detects this as a redirect loop and shuts down.

I've noticed that new installs, if started with just a blank set of database tables and a LocalSettings file (without running the MediaWiki installer again for the new wiki), are prone to go into an endless HTML redirect loop because of this code. Attempts to run maintenance/update.php from the command line may also abruptly end with errors if the extension is trying to create this page during the "update.php" run and the database is not yet updated to the latest MW format (and therefore not ready for the template creation attempt).

There needs to be some error handling; if the creation of the placeholder template fails, don't just keep trying forever - at least not if this is going to return errors or redirect loops. --[[User:Carlb|Carlb]] 14:12, 9 November 2009 (UTC)

== [SOLVED] White page after including Semantic Media Wiki Extension in LocalSettings.php ==

Hello,
I installed the Semantic Media Wiki extension on a Media Wiki 1.16.0
According to the install notes on the page I appended the following two lines to the LocalSettings.php:
 
include_once("$IP/extensions/SemanticMediaWiki/SemanticMediaWiki.php"); 
enableSemantics('filerepos.de'); 
 
After that I get a blank page on every URL of the Wiki.
Set error_reporting to E_ALL (in LocalSettings.php, SMW-Config-Files) but also got a blank page.

Also tried the hint from the Semantic Wiki Site with no success:

ini_set( 'memory_limit', '100M' );

When I comment the both lines out everything works again.

(Setup: Mediawiki 1.16.0, PHP Version 5.2.6, MySql 5.0.45, Semantic Media Wiki Extension 1.5.3 stable)

Would apreciate any hint.
:This page is only for support for the DynamicPageList extension. You're more likely to get a response if you ask the SMW people. With that said, Did you add the:
error_reporting(E_ALL);
ini_set("display_errors", 1);
as the very first lines of LocalSettings.php (directly below the opening <?php )? If that still doesn't work, try setting error reporting to E_ALL directly in your php.ini file. You can also try checking your webserver's error log as well (doesn't usually have php errors in it, but if its some sort of config problem with your webserver it might have relevant information). [[User:Bawolff|Bawolff]] 22:31, 26 November 2010 (UTC)

 
Thanks for the reply...think ini_set got the errorReporting working.
Now there is some output I can work with:
http://www.mediawiki.org/w/index.php?title=Extension_talk:DynamicPageList_(third-party)&action=edit&section=38
Call to undefined function enableSemantics() in /srv/www/vhosts/filerepos.de/httpdocs/websites/semwiki/LocalSettings.php on line 138

[SOLVED] I accidently downloaded the wiki and the extension with different user...so the wiki wasnt allowed to access the extension.
Changed extension files owner to the same owner as the wiki and so everything works now.
Thanks for the error reporting hint which allowed me to find my mistake

== Undefined index and .default ==

I try to make the DPL-Extension read out a category and get the parameters of a template in the articles of this category. They are meant to be used in another template. I saw another wiki which did it the same way as I did, but I get a strange Error while using the preview on this:

<pre><DPL>
category = Some Category
mode = userformat
includepage = {Template in articles} Kr
allowcachedresults = true
</DPL></pre>

"Notice: Undefined index: tip ... EditPage.php". The line is this: "$tip = $tool['tip'],".
This is strange but probably not that important. The real problem I got ist, that the extension always adds an ".default" at the end of the template. So I get a long list which just says "Template:Template in articles Kr.defaultTemplate:Template in articles Kr.default...".I don't really get the origin of the problem and couldn't find an answer anywhere.
I didn't change anything in the basic code of mediawiki, except for some extra buttons i added in EditPage.php. There are also no extensions, that could affect the DPL extension.--[[User:Eski123|Eski123]] 12:14, 2 January 2010 (UTC)

:My five cents on this: according to [http://semeb.com/dpldemo/index.php?title=Includepage#include_contents_related_to_templates doc], the DPL engine calls a template with the additional sufix ".default" when a page listed in the result does not use the specified template. [[User:Pierrem100|Pierrem100]] 14:49, 26 October 2010 (UTC)

== Problems with missing subheads ==

DPL is apparently crashing when used with a subhead that doesn't exist on one of the pages included by Category.

I have the following DPL code on a page called "Current projects":

=Projects in process=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects
|include = #Project steward, #Need
|includetrim=true
|table=class="sortable", Project, Steward, Need
}}

=Completed projects=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects, completed
|include = #Project steward, #Final accounting
|includetrim=true
|table=class="sortable", Project, Steward, Final Accounting
}}

The first DPL call works if I temporarily clip out the second DPL cal, but including the second DPL call displays:

:Fatal error: Call to a member function getPrefixedDBkey() on a non-object in /Library/WebServer/EcoReality/wiki/includes/parser/Preprocessor_DOM.php on line 994

I then looked over the pages in the Category "Projects, completed" and discovered several of them did not have a subhead called "Final accounting." These are old pages, and this worked once upon a time!

For now, I've removed "Final accounting" from the second DPL call, but it seems it should behave better than this in such a case, no? Have I messed up something to cause it to misbehave this way?

See it fixed at: http://www.ecoreality.org/wiki/Current_projects .

== Spaces and underscores ==

It seems that the "titleregexp" parameter doesn't interpret spaces and underscores the same way. In fact, since page names can't have spaces in them, any time there is a space it just flat out fails. This would ordinarily not be such a big deal, so, okay, you learn not to use spaces, however i have a template for detecting direct subpages of a page (but not sub-subpages). the regexp is {{PAGENAME}}/[^/]*$ however, if used on a page with a space in the name, {{PAGENAME}} returns a space there where dpl requires an underscore. It seems to me that spaces and underscores should be totally interchangable in dpl, as they are in the rest of MW. [[User:DeFender1031|DeFender1031]] 11:22, 29 January 2010 (UTC)

== Great and easy: Searchable Tables ==

I use the TableTools (Firefox-Extension) to search the tables generated with DynamicPageList (Mediawiki-Extension); see here [https://addons.mozilla.org/en-US/firefox/addon/2637]

With the Firefox-Extension installed you can right-click into a table and choose
# show Filter (german: Filter anzeigen)
# show Searchfilter (german: Suchfilter anzeigen)

With the first you get lists where you can choose an item in the table-heading and get all the rows matching this item.

With the second you get searchfields in the heading to use for a wildcard-search.

Both functions are very (!) usefull for the DynamicPageList-tables. But it is not userfriendly for less sophisticated users to right-click to get the function. I would like to put such functionality with an easy dpl-command into the heading, similar to the magicword "wikitable" or "sortable": "searchable". Now I wonder if it would be possible to integrate such a great feature directly into DynamicPageList??

I hope that others are also interested in such a feature.

== Setting parameter without using template? ==

Hi, it seems that all parameters are set in a template. In my wiki, there is a pretty standardized section and i would like to implement DPL on it. It's not a template but just a list of 1....2....3...list. Is there any markup tag that i can tell DPL that item01 = 1.. ; item02 = 2... ; item03 = 3.... ?

The current method is like this. It's actually good but in a FCKeditor-based Wiki, it may be too difficult to ask laymen to learn it.

== MediaWiki 1.17alpha and [[bugzilla:22675|bug 22675]] ==

I downloaded the daily build of MW 1.17 alpha (12:13, 20 June 2010 - revision: r68310) core code and extensions and this seems to be broken. Symptoms are the same as reported in [[bugzilla:22675|bug 22675]] four months ago, the output appears on-screen as an HTML source code dump (<a href="...) instead of as hyperlinks in their clickable form.

Hi, I'm using DPL and imagecontainer, but I'm not sure what the problem is.

:imagecontainer might be disabled - it needs the functionalrichness parameter to be at least 2. (if that is the case, I have no idea if there would be an error of some sort. this is just a guess, I don't know much about DPL2).

== Parser function after a backup ==
I seem to have a strange issue after restoring a backup of my wiki on another computer. Both computers are using DPL version 1.8.9. I have a bunch of pages that use the parser function variant (<nowiki>{{#dpl: ...}}</nowiki> through some templates. For some reason, they display incorrectly on the new computer. Basically they just show the function then all of the parameters in what looks like a PRE tag.

The parser tag works fine. I can take the same queries and change them to the tag variant on a test page and they work great. The trouble is I need these to work in templates, so the function is needed. Anybody have any ideas what would cause this? - [[User:Glycerine102|Glycerine102]] 14:50, 19 July 2010 (UTC)
:No idea whats causing your original issue, but you can also try <nowiki>{{#tag:DPL</nowiki> - see [[Help:Magic_words#Miscellaneous]]. [[User:Bawolff|Bawolff]] 01:42, 20 July 2010 (UTC)

== Parser versus Hook change? ==

Does anyone know what might have changed in the code to cause the following statement to no longer include the category here, as seen below:

<code><nowiki>{{#dpl:category={{PAGENAME}}|category=Application Error|notcategory=Subtopic-topic|replaceintitle=/{{BASEPAGENAME}}\//,|format=,\n*,[[{{BASEPAGENAME}}/%TITLE%{{pipe}}%TITLE%]],|notnamespace=Category|noresultsheader=There are no symptom entries for this application.[[Category:Articles with no symptom entries]]}}</nowiki></code>

The odd thing is that it is actually working for one of my templates. I resolved the issue by converting to the <DPL> hook instead. Still, it seems strange that this suddenly stopped working. [[User:Thorncrag|Thorncrag]] 20:31, 18 August 2010 (UTC)
:And I have just discovered that my workaround will not suffice because using the hook causes replaceintitle to not function the same as when using the parser call instead. [[User:Thorncrag|Thorncrag]] 21:18, 18 August 2010 (UTC)
::Note, as said in the thread above this one, you can also use <nowiki>{{#tag:DPL</nowiki> to access the <DPL> tag as a parser function which should have the exact same behaviour as <DPL> (compared to <nowiki>{{#dpl:</nowiki> which has slightly different behaviour compared to <DPL>).

:I'm not sure what the number of 70760 is, however as far as i know they still play nicely together as long as the version of DPL is post [[rev:68812]]. However with that said, the categorylinks table changed quite a bit in 1.17 (aka current svn head). Some features might break in subtle (or perhaps not so subtle ways) because of that. It will certainly be less efficient for plain ole' category listings (but then again this is a very inefficient extension, so if you care about efficiently, I doubt you'd use it).

== DPL & Nested Templates? ==

I may be missing something so I am posting the question here. Can DPL query variables passed to a nested template? Meaning, ...
* You have a page named Resource1 which uses a template called ResourceType1 which is a member of the Asset Category.
* Within template ResourceType1 you pass variables to and call the template called AssetInfo.
* You then construct a DPL query which based on the Asset category queries all pages member of Asset and lists the variables found on the nested AssetInfo template

The rational for such a construct would be to list AsseInfo common to all resources which may use different ResourceType templates (type1, type2, etc) but are all members of Asset. Since the include/includepage line in DPL table output must be consistent, querying the nested common template seems the best approach but does not work.
please advise?, thanks ahead of time for replies [[Special:Contributions/208.79.244.111|208.79.244.111]] 23:23, 4 October 2010 (UTC)

== Replace in title breaks with titles that contain parentheses ==

I've just discovered that an article title which contains parentheses causes the replaceintitle statement to break in that it will no longer perform any longer. In context, I have a replaceintitle which is supposed to remove the BASEPAGENAME from the title or an article that is a subpage, so that when I output title I can output only the name of the subpage instead of the entire trail. I still need to do further troubleshooting to see if it is actually BASEPAGENAME or %TITLE% which is breaking. Nevertheless, it's clearly an issue with the extension. [[User:Thorncrag|   Thorncrag  ]] 22:41, 7 October 2010 (UTC)
:Note, per issue I reported above, I changed to #tag:DPL .... which is what bawolff had suggested. Unfortunately I misread it a long time ago... Anyhow that seems to have sufficiently worked around this issue. [[User:Thorncrag|   Thorncrag  ]] 23:30, 7 October 2010 (UTC)

:::<nowiki>{{#tag:DPL</nowiki> Should take the exact same syntax as <DPL>. If there's something that works for <DPL> but not <nowiki>{{#tag:DPL</nowiki>, that's probably a bug in mediawiki (core) not the extension, since converting <nowiki>{{#tag:DPL</nowiki> to <DPL> is part of the parser. (With that said, I'm not sure how it'd help you with your issue, since the two should be exactly the same with exception of parsing the args before passing to DPL.).

== Use with TreeAndMenu Extension ? ==

Hi,

I only need this:

{{#dpl:category=Foo|format=,**,[[%PAGE%]]\n,}}

..To dynamically add all pages to a tree that is created by the Extension TreeAndMenu.
I´ve tested it and it works great. Though I´m planning an opened wiki I´m a bit scared
about the red box on this extensions main page telling me that it has a major security
risk.

Is it possible to enable this extension only for a specific (admin) page or to eliminate
the security risk by adding some contraints?

Thanks in advance!

Hi again. Sadly that was not the solution. If the option to allow DPL only on protected pages is enabled this also affects the NavTree (Extension: TreeANDMenu) that needs DPL to work propperly. What I need is DPL to only work in the sidebar :-). But I don´t know if that is easily possible?

== Tree and Menu and DPL - Advanced use ==

I'm currently using Tree and Menu and DPL to generate lists as shown in the Example. Works fine.

{{#tree:id=ToolsMenuTree|openlevels=0|root=Tools, Tips and best practice|
* [[Tools and Tricks|Overview]] (Introduction Page)
{{#dpl:category=Tools and Tricks|format=,**,[[%PAGE%]]\n,}}
}}

The problem is that our wiki will have a lot of pages and subpages, making the list expand really fast with similar named entries such as:
Outlook
Outlook/Installation
Outlook/Usage

With the example structure above, is there a way to automatically create subfolders for all subpages using DPL syntax? Should be looking something like that
**Outlook
***Installation
***Usage
Any hints would be greatly appreciated. (Mike)

== Breaks when using ordermethod pagesel ==

I've run into an interesting problem. When attempting to generate a list using "linksfrom" and setting ordermethod to "pagesel", the parser breaks with the following error:
<pre>SELECT DISTINCT `page`.page_namespace as page_namespace,`page`.page_title as page_title,`page`.page_id as page_id, pagesrc.page_title as sel_title, pagesrc.page_namespace as sel_ns, CONCAT(pl.pl_namespace,pl.pl_title) AS sortkey FROM `pagelinks` as plf, `page`as pagesrc, `page` WHERE 1=1 AND `page`.page_is_redirect=0 AND `page`.page_namespace = plf.pl_namespace AND `page`.page_title = plf.pl_title AND pagesrc.page_id=plf.pl_from AND ((plf.pl_from=0)) ORDER BY sortkey ASC LIMIT 0, 500

Error message is:
Unknown column 'pl.pl_namespace' in 'field list' (localhost) </pre>
What's interesting is that this error does NOT occur if I change "linksfrom" to "linksto". What's also interesting is that on a cursory check of DPLMain.php for malformed code and found that the column pl.pl_namespace isn't even referenced in the "linksfrom" section, but is referenced in the "linksto" section, but I may not be looking at it right.

== Show images of a category including links to pages using these images! ==

Hi all,

I have a difficult question. I would like to create a gallery like that:

{{#dpl:
|category=Oneofmycats
|namespace=Image
|format=«gallery»,%PAGE%¦%NR%. %TITLE%\n,,«/gallery»
}}

That works great. But now I would like to have the name of the page (all of my images are at least only used on one page!) which makes use of the image as image text (not TITLE). In addition to that the name of the page should be a linkt to the page! So it would be possible to show all Images of a certain category including linkt to each page using this image (there is only one page!).

Found this code here:

{{#dpl:
|imageused=myimage.jpg
|format=,[[%PAGE%]]\n,,
}}

But I don´t know how to merge this two operations to one big thing!

Hope you understand what I mean :-).

Thanks in advance.

== DPL for category page – order by second name? ==

I'm using DPL for a personalized category page because I didn't like the MediaWiki-own view. Everything works fine but there is one point I despair of. For the category of persons I want the list to be ordered by second name. In the standard category view this issue is solved by a tag on every page that tells MediaWiki how to order, e.g. on the page "Angie Gielach" <nowiki>[[Kategorie:Personen|Gielach]]</nowiki> to have it listed under "G" instead of "A".

In DPL I use the following code to display the pages of my category "Personen" alphabetically:

<pre><nowiki>
===A===
<DPL>
category = Personen
format = ,\n* [[%PAGE%|%TITLE%]],,
title<=B
</DPL>
</nowiki></pre>

Has anyone a solution for this?

:You have to use a subquery which will result in all pages with the temnplate being returned but hiding those which do no match your age criteria (for which you'll need [[Extension:ParserFunctions]] for the check). A very dirty solution tho. --[[User:Subfader|Subfader]] 19:04, 24 May 2011 (UTC)

== Intercept a list of articles by alphabetic character ==

I have a list of articles on people, sort by last name (via sortkey). To make it easier for users to find a name in the list I want to intersect the list with subheadings showing the alphabetical character:

====A====
* Otto Ader
* Anton Albers

====B====
* Chris Bill
...

Any ideas? --[[Special:Contributions/188.98.11.250|188.98.11.250]] 20:42, 1 June 2011 (UTC)

Thanks for your answer. I now use this:

<pre>
<DPL>
category=Personen
mode=category

</DPL>
</pre>

Together with the setting <code>ExtDynamicPageList::$categoryStyleListCutoff = 400;</code> it outputs a list separeted by the alphabetical character but without columns. Now there is one new problem appearing: Somehow the parser doesn't change the html-tags produced by the DPL-plugin into wiki-links. Thats what I get:

===A===
* <html><a href="/index.php/Otto_Abetz" title="Otto Abetz">Otto Abetz</a></html>
* <html><a href="/index.php/Alma_de_l%27_Aigle" title="Alma de l' Aigle">Alma de l' Aigle</a></html>
* <html><a href="/index.php/Helmut_Amanshauser" title="Helmut Amanshauser">Helmut Amanshauser</a></html>

== Problems with VariableExtension ==

I'm having problems with using the VariableExtension together with DPL, here is an example:

<pre>
{{#vardefine:pagetitle|Main Page}}

==First==
{{#dpl:titlematch={{#var:pagetitle}}}}

==Second==
{{#dpl:titlematch={{#var:pagetitle}}}}
</pre>

I'm using Mediawiki v1.17, Extension:VariableExtension v1.3, and DPL v1.8.9 (the MW1.17 build, DynamicPageList-MW1.17-r76531.tar.gz).

The output from the first call is not the same as the output from the second call. Shouldn't it be identical? The first call returns "Main Page" and "Talk:Main Page" as expected, but the second call instead gives this strange error message:

:Extension:DynamicPageList (DPL), version 1.8.9 : ERROR: No selection criteria found! You must use at least one of the following parameters: category, namespace, titlematch, linksto, uses, createdby, modifiedby, lastmodifiedby or their 'not' variants

: I have reported this above already, but now I looked into it a little bit further. Seems like this is a problem ob ''DynamicPageList''. This extension shouldn use <code>Parser::parse()</code>, the code [http://svn.wikimedia.org/doc/classParser.html Parser class documentation] states that this function should NOT be called recursively! Since this function is called for page rendering, you shouldn't use it within this extension. Instead you should use <code>Parser::recursiveTagParse()</code>.

== Question about "includematch" ==

I use this great extensions in two of mine wikis. In the last times, i have some problems with includematch.
My Wiki is about Final Fantasy XIV Online, for info ;)

NPCs are selling some Items, the item goes in the category:example sells from NPC.
Now, some NPCs sells example-head, examplefeed, example-earring. If i create now the Article examlpe,
i use this DPL:
<pre>
{{#dpl:
|category = {{SUBPAGENAME}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{fixapos|{{fixtick|{{fixparen|{{SUBPAGENAME}}}}}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

Here i use the _Template:Sellsrow to get the Price and the Template:NPC dpl Zones to get all other datas.
In the Template:Sellsrow, i define '''Item'''. Thats why my includematch say get where Item = <nowiki>{{SUBPAGENAME}}</nowiki>.
So, my Articles shows me now in the Table all sellinginformations about:
*example
*example-head
*examplefeed
*example-earring

i try'd some other includematch variations like this:
<pre>
{{#dpl:
|category = {{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

but at least, i have allways the Same problem. It shows me all what that NPC have, where example is in :\
The only what i want to see, is the Data for example >.< Someone knows how i can fix it? [[User:Yukii|Yukii]] 12:52, 17 October 2011 (UTC)

::I'm not quite sure I understood everything you said, so in case you want to clarify, you can tell me in German. // Ich bin mir nicht ganz sicher, dass ich alles richtig verstanden habe, und falls nicht, dann kannst du es gerne auf Deutsch nochmals erklären.
::The problem is, as far as I can see, that you never included the line "Item=..." in your DPL call; you only called to include "Price=..." parameter in the {Sellsrow} template. The includematch function works only, if you include the respective parameter, so in order for it to work, you need to change <code>{Sellsrow}:Price</code> to <code>{Sellsrow}:Item:Price</code>. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 13:43, 22 March 2012 (UTC)

== Warning about $maxResultCount ==

Just as a heads-up, <code>$maxResultCount</code> is '''not''' a limit on DPL's results, but a limit on the amount of rows pulled from the database. '''That is not the same thing'''. For example, the DPL query...

<DPL>
includematch=/\|\stemplate-attribute\s=\svalue/s
titlematch=Foo%
category=Foos
</DPL>

...will '''first pull all pages beginning with "<code>Foo</code>" in the category "<code>Foos</code>" from the database''', and only '''then''' check for the <code>includematch</code> pattern. In other words, if <code>$maxResultCount</code> is 500 and you have 800 <code>Foo%</code> pages in the <code>Foos</code> category, '''''even if just ten of those match your <code>includematch</code> pattern, you will probably not get all ten'''''.

Our solution was to remove the limit entirely (<code>$allowUnlimitedResults = true</code>), because our wiki is private and we have a strong control over authorship.

Your mileage may, of course, vary. -[[User:Pinkgothic|pinkgothic]] 13:32, 30 November 2011 (UTC)

== Null edits (or dummy edits) required for updating DPL listing ==

The wiki I administer makes a huge use of DPLs for constructing lists of pages and controlling workflows--very well might I add.

One problem that I have perennially run into however is the need to execute a null edit in order for pages to properly show up in a DPL when the DPL is grabbing based on, for instance, page category. What I don't understand is that when accessing the page in question the category is correct, but the DPL listing the page will not include the page in its list until executing a null edit on the page. I'm fairly knowledgebale about this extension but I have not come up with a solution to this problem. I've even tried using updaterules to "touch" the page when the list is built, but that feature does not seem to be usable at this point.

Since the page shows the correct category, and the job queue is empty, I can't actually figure out why this is happening. The only thing that I can think of is that the DPL is stored in a cache; however, that should not be causing this since cached results are supposed to be disabled by default. I do have MediaWiki parser cache set to enabled as well as file cache, but disabling these seems to have no effect on the symptom. Any thoughts on this? [[User:Thorncrag|   Thorncrag  ]] 18:40, 12 January 2012 (UTC)

== "skipthispage" - not bolded when created by DPL ==

Hi! I'm working through the book MediaWiki and Beyond. Great book, but I've run into something that doesn't seem to be working. In the book it says that if you use the 'skipthispage' variable and set it to false, not only will the page you are on show up in your list (in this case a navigation list), but since its pointing to itself, it will default to bolded text rather than a link. I don't seem to be able to get that behavior though. If I put a link to the page within itself, that will bold and present just as text, but not when it comes through the dpl command. Any ideas why?

== DynamicPageList only works with global $wgRawHtml set to true. ==

Between MediaWiki version 1.15 and 1.16 the way the < html > tag is handled changed. As a result, the DynamicPageList extension's abuse of the global $wgRawHtml setting to temporarily enable raw HTML content is broken. The normal way (to my knowledge) for an extension developer to embed raw HTML is to create one or more markers and then to post process the content and replace the markers with HTML after MediaWiki has done all of it's HTML stripping.

== Where can I download DPL2? ==

First, I don't know git very well but it seems that all of the links to download DynamicPageList2 are broken. Can anyone point me to a version of DPL2 that works with MediaWiki 1.19? Thanks.

== Attempting to use DPL to create a table "on-the-fly" on any given article page by pulling from a list on a page; Getting error message: %DPL-1.7.6-WARNING: No results! ==
* Hi, so my goal in this scenario is to create a table on-the-fly using DPL and put that table on any given article page (I've opted to do a template call to facilitate this) -- and so part of the problem has been to figure out which of the DPL commands are best suited to accomplish this. I started with table and tablerow and initially got the results I was looking for on simpler test examples. But now I'm getting this error %DPL-1.7.6-WARNING: No results! and I can't find my bug! So yesterday I started looking at the secseparators and multisecseparators commands, but the syntax is killing me and they're just a bit too tricky for me right now (I just started learning/implementing DPL). In the DPL Manual it even suggests sticking with "table" and "tablerow", and that's what I'd like to do.
* I'd be grateful for some help figuring out where I took a wrong turn.
* One thing I saw yesterday was that I had misnamed the first parameter - i.e., Drug Code instead of Pfizer Drug Code. So I corrected that. It still didn't work. So I created a new Template:Drug Info 5 and Template:Drug Info5.dpl - suspecting that maybe there was something I wasn't aware of in the functioning of a phantom template where even if I fixed the parameter name in the dpl template, the phantom template might not pass the parameters through properly (?).
* Further down I list an example that did work. That's the one I built upon to try to get this one to work.
* Many thanks for your reply and insight. Cheers, Jeff Western cell: 323.449.7944

::Hello, I wish I could give you a link to the wiki, but it's an internal wiki to the company and a network credentials are required in order to even view the wiki. Good news is that the solution to this first part of my problem is to use <tt>titlematch=</tt> in the DPL, not <tt>linksto=</tt>. I admit, I really didn't quite understand how the linksto command works, but titlematch definitely worked.

:::The tablerow in the latest statement shouldn't do anything as the entire output of a phantom template should not be changed by tablerow.
:::The linksto statement is selecting pages basically the same way as the "what links here"-tool.
:::The way you use the titlematch statement should only give you one page, the very one you put into the statement. If you want to select several pages with titematch, you will have to use "_" as a one letter wildcard or "%" as a wildcard for any amount of letters; for example "titlematch=c_t" would give you "cat", "cut", et.al. yet "c%t" could even give you "cannot", "carrot", ...

::Theaitetos, I much appreciate your looking at this and answering with this code. I just tried it and it works. I got my code with the phantom template to work as well, but yours is a bit cleaner of course. I do get some multiple hits on a couple of the drugs, not sure why, but I suspect it might be my error somewhere (maybe too many category tags?!); I also got multiple hits with my code.
::(7/12/12)'''''On another note, the last piece of the puzzle for this first User Story that I'm trying to solve right now is this...''''' '''Once the user is on a Disease page, how do I "automate" (from the user's pov) the selection of drug(s) that they wish to associate with the disease?''' (...which then leads to the creation of the on-the-fly-dpl-table, which is pretty much working now -- thanks again!) So, I've checked with the internal IT dept here, and Javascript drop-menus are out of the question -- too bad, seems that's the nicest way to implement this. Raw HTML is not allowed currently on the company's internal wiki (and discouraged in general), and Javascript is only allowed by changing Common.js – which is a javascript which is triggered on every page load on the wiki. So they're telling me it's very inefficient to include Javascript on their internal wiki. Okay, so the approach I just hit on yesterday (brainstorming in my head while smoking a cigar!) is to do the following:
* Created a template: <nowiki>{{DPL for EQDD Diseases List with include redirects}}</nowiki>
* This template has DPL: <nowiki>{{#dpl: |category=EQDD Diseases List |mode=none |redirects=include |format=,\n* EQDD for [[%PAGE%|%TITLE%]],, }}</nowiki>
* Then I do the template call on any Disease page where I need it and it works, producing:
:::EQDD for Age Related Macular Degeneration
:::EQDD for Allergy and Respiratory
:::EQDD for Asthma
:::EQDD for Bunionectomy
:::EQDD for Chronic Abacterial Prostatitis
:::EQDD for Crohn's Disease
:::EQDD for Crohn’s Disease
:::EQDD for Dental Pain
:::EQDD for Discoid Lupus
:::EQDD for Endometriosis
:::EQDD for Inflammation
:::EQDD for Lupus
:::EQDD for Lupus Nephritis
:::EQDD for Male Erectile Dysfunction (MED)
:::EQDD for Ophthalmology
:::EQDD for Pain
:::EQDD for Primary Dysmenorrhea
:::EQDD for Systemic Lupus Erythamatosus (SLE)
:::EQDD for Ulcerative Colitis
:::EQDD for Women's Health and Urology
*'''But here's is where I run into a stumbling block...''' '''''I've discovered that when I try to run the subst: command on dpl, I just can't get it to substitute the straight text for me, e.g., <nowiki>{{subst:{{DPL for EQDD Diseases List with include redirects}} }}</nowiki>. What it does is always gives me the dpl in the substitution. What I need''' '''''I think!''''' '''is the straight text so that I can manipulate it. Because clearly, one cannot manipulate the output from a template call, or DPL, as it is just for viewing, right. So unless there is a way, using DPL commands, to further manipulate the data (on-the-fly by the DPL) such that a user can somehow select one of the diseases (list above) -- then I don't see any other way to do this. I suppose they could just highlight the text in the page name (from the list above), copy it, and paste it into a link on that Drug page, e.g., <nowiki>[[EQDD for Ulcerative Colitis]]</nowiki>
*''''' You see, what I'm trying to do is a work-around to not having a drop-down menu option for folks to be able to select from a list of already existing Disease pages. This way, they cannot possibly enter the name of the Disease page incorrectly. So what I'm trying to do is figure out a way to take a Disease page name (exactly as you see them listed above) and turn that page name into a <nowiki>[[link]]</nowiki> on the drug page -- thus the association between the drug and the disease. Then I use the linksto= command, and I get a listing of just the drugs that have been selected and associated with a disease, displayed by the on-the-fly-dpl-table on the Disease page. Again, any suggestions would be greatly appreciated. Thank you.

:*As far as javascript is concerned: There should be some javascripts coded into the core Mediawiki css anyway, so you could try to use that stuff to do some drop-down menus. For example, try to see if the following table works in your wiki:
::* Thank you for this great suggestion! This would be a terrific solution but unfortunately it doesn't run on the company's internal wiki. I'm thinking they don't have any Javascript enabled..? When I put this table into the internal wiki, it builds a table just fine, but it's not interactive (won't expand, collapse) like it does here.

:*As for the substitution: You have to substitute a dpl-call by adding the "subst:" into the dpl-call, i.e.: <code><nowiki>{{subst:#dpl:</nowiki></code>
::* That's ''AWESOME!'' Thank you -- just tried it and it works great! You see, what I'm after is implementing a User Story where the goal is associate a drug with a disease and in order to do this, I must ensure the end-user cannot enter a link incorrectly... ergo my interest in drop-down menus! Shame they won't work on this company's wiki. Anyway, so my work-around is to grab all the disease pages (they're tagged by Category of course) and then wrap <code>[[..]]</code> square brackets around the disease page name (article name) and then instruct the end-user to copy that text exactly (with the brackets) and paste it into the Drug page. So that creates the link, which <code>linksto=</code> then uses to pull up only those Drug pages that have been ''associated'' with a particular Disease page. Of course down the road, it would be nicer to have that <code><nowiki>[[link]]</nowiki></code> get inserted in a more automated fashion -- to avoid any possibility of the user making a mistake.
:*It's hard to imagine what output you specifically desire without looking at it. Could you put one example down here, so I can see it? I.e. the direct output you desire, no dpl anything, just how you want it to look like and I'll see if I can find the proper code to produce said output.
::*Yes, I can appreciate that. That's why I wear multiple hats on this job - Business Analyst, to understand their needs and document requirements - Developer, to implement the User Stories - and PM to hopefully make all this happen in time. So next week I'm going to set about updating my User Story diagrams and I'll start with this user story, and I'll list it here for you to see. Again, many many thanks for your great suggestions. It's been a hard week -- what with going down blind alleys with subst: -- and your hint will I think get me there!
:*About having multiple results: You can disable multiple results by adding the parameter <code><nowiki>distinct = strict</nowiki></code> to your dpl call.

How to list only the labeled sections, without the pages not containing the section: <pre>{{#dpl:debug=1|category=Book|include=title}}</pre> will list the pages of category Book, even if they do not have <pre><section begin=title /></pre>. The includematch cannot be used, because the include doesn't call the whole section, but only the content of the section tags. Any idea ? --[[User:Fxparlant|Fxparlant]] 11:06, 14 July 2008 (UTC)

== Catch a template parameter ==

I am looking for a way to use DPL to catch, not the title of a page, but the parameter of a template:

if a page calls the template '''<nowiki>{{Temp|param1|param2|param3}}</nowiki>''', how to catch the param3 in another page, with a query on the first parameter and the second ?

--[[User:Fxparlant|Fxparlant]] 13:08, 7 August 2008 (UTC)

:You can use phantom templates for that purpose. DPL will call the phantom template instead of the original one and pass all parameters to the phantom template in the same way as they were passed to the original template. And within the phantom template you can do whatever you like - which means that you can simply output the third parameter.

== Tweak to make DPL backward compatible with DynamicPageList2 <suppresserrors> parameter ==

I'm one of the admins at ChoralWiki (www.cpdl.org), a free Public Domain scores library, and we use [[Extension:DynamicPageList2|DynamicPageList2]] a lot in it with parameter <suppresserrors> set to 'true'. We were doing an upgrade test to the newest version of DynamicPageList and after the upgrade all our DPL queries started showing this warning:

%DPL-1.7.4-WARNING: Unknown parameter '$0' is ignored. Help: available parameters: suppresserrors.

After a quick research we realized that parameter <suppresserrors> is no longer supported by the new DPL versions. It would be a pain to edit all pages where it appears, so we decided to tweak the DPL code to recognize it and behave as expected. We made the changes below, tested it and it worked fine. So we decided to post it here in case someone else faces the same problem. All one needs to do is to add the following lines in red to file ''DinamicPageList2.php'':

line 682:

/**
* noresultsheader / footer is some wiki text which will be output (instead of a warning message)
* if the result set is empty; setting 'noresultsheader' to something like ' ' will suppress
* the warning about empty result set.
*/
'suppresserrors' => array('default' => 'false', 'true', 'no', 'yes', '0', '1', 'off', 'on'),
'noresultsheader' => array('default' => ''),
'noresultsfooter' => array('default' => ''),

line 1157:

$bSuppressErrors = self::argBoolean(self::$options['suppresserrors']['default']);
$sResultsHeader = self::$options['resultsheader']['default'];
$sResultsFooter = self::$options['resultsfooter']['default'];

line 2095:
case 'noresultsheader':
$sNoResultsHeader = $sArg;
break;
case 'suppresserrors':
if( in_array($sArg, self::$options['suppresserrors'])) {
$bSuppressErrors = self::argBoolean($sArg);
if( $bSuppressErrors )
$sNoResultsHeader = ' ';
}
else
$output .= $logger->msgWrongParam('suppresserrors', $sArg);
break;
case 'noresultsfooter':
$sNoResultsFooter = $sArg;
break;

After the change, if <suppresserrors=true> is used in the query and 0 pages are returned, it won't show any warning message; if <noresultsheader='text'> is also used, it will show the 'text' supplied. [[User:Capmo|Capmo]] 13:40, 18 September 2008 (UTC)

== Index (List of index-terms) for a book ==
I am experienced in editing wikipedia-articles. Now I want to use mediawiki on my server to write a book (around 1.000 articles). I want to mark index-terms in articles and have one page with a sorted index.
The book will exist of 1.000 articles. So it is no problem to generate the article dynamicaly when I will open the index.
Is DPL the right extension to do the job?

How to mark the index-terms in articles?

: Regards, Jan

::Hello Jan, creating a permuted index is a challenge because DPL normally walks sequentially through all articles which match the selection criteria and collects the desired information (in your case template invocations). In your case one would have to store the collected data (using the ''arrays'' extension ), re-arrange the order and then produce the output in a final step. With less than 10 lines of code all this is possible:
::<center>see     ''' http://semeb.com/dpldemo/index.php?title=DPL_Example_017 ''' </center>
::I know SMW and think it is powerful for expert users. The idea of DPL is to use MW as it is without introducing new syntax for those users who ''write'' articles.

== Problems ==

Hi. I have a problem with labeled section transclusion, the ''section'' tags show up along with the transcluded text. This problem only showed up recently; the page was doing fine four months ago when I left it. When I came back a few days ago, no changes have been made to the articles but the DPL pages have broken formatting. It is a Wikia page and I asked the Wikia staff about it too, but they haven't recognized something from their end being the source of the problem either. So here's the problem. Instead of this:

http://img.photobucket.com/albums/v59/daarklord/ForumGraphics/DplWtf01.gif

I get this instead:

==A Bug?==
I use DPL together with MediaWiki 1.14.0, SMW 1.4.2, DPL 1.7.9 If I follow a link, that is done by the Call-Extension, the CSS-File of SMW is not included. What can I do? The main problem: The field “smwsortkey” is not more hidden, because the style for it is not included. Christian Weiss 14:44, 27 May 2009 (GMT+2)

:Please give more details. I assume that the problem has nothing to do with DPL; this means that it also occurs if you use the Extension:Call from the browser's URL-line or within a normal document like this <nowiki>[[Special:Call/:Mypage,a=b]]</nowiki>. I don´t understand your remark about a "style". Are you talking about css? Can you reproduce the error on the [http://semeb.com/dpldemo dpldemo website]? It has DPL 1.7.9 and SMW 1.0 installed.

:::It's like you said: I call a Template by the Call-Extension, the DPL-Calendar ":Current events" for example. If it's included the normal Way in a Page, in the HTML-Source the "SMW_custom.css" and the "SMW_sorttable.js" are included. If the Template ist called by the "Call"-Extension those files are not included in the HTML-Source. A workaround ist to include those files in the Common.css and Common.js for Skins, so it is included everytime. For the SMW_sortable.js I get then 2x sortbuttons :-) I think, the Call-Extension ist part of your Pakage, so I write my Problem to you. Christian Weiss 10:06, 06 Jun 2009 (GMT+2)

== LoF ==

I sthe LoF ment to be set as global in LocalSettings? I'd prefer it as option per DPL call. So I want to use a complex DPL call I would set LoF = 3 or sth inside the call.

== DPL Doesn't Work after MW Upgrade from 1.13 to 1.15.1 ==

Hi, I have a private wiki we use as a content Management system at work. I updated the wiki from MW.1.13 to MW.1.15.1, and suddenly DPL doesn't work. For example, I have a page for each of our main applications, with a supbage called 'Troubleshooting'. Below that are more subpages, one for each troubleshooting document. The '/Troubleshooting' subpage consists entirely of DPL to list the child subpages for a user to browse and jump to.

For example (changing the page names to protect proprietary information):

We have a set of pages like so:

* Main:Zazaza
* Main:Zazaza/Troubleshooting
* Main:Zazaza/Troubleshooting/Error 51 - File not Found
* Main:Zazaza/Troubleshooting/Can't Save Configurations
* Main:Zazaza/Troubleshooting/App Crashes if User Chews Bubble Gum

The top page, Main:Zazaza, describes the application and has a link to Main:Zazaza/Troubleshooting.

Main:Zazaza/Troubleshooting consists entirely of DPL code that will list the three 'troubleshooting' child subpages with links. This page's DPL Code is as follows:


<DPL> 
titlematch=Zazaza/Troubleshooting/% 
notnamespace=Image 
notnamespace=Image_talk 
notnamespace=Template 
notnamespace=Template_talk 
replaceintitle=/.......Troubleshooting./, 
</DPL>


Previously, the DPL worked, and a user browsing to the Zazaza/Troubleshooting page would see a list of clickable links:

Error 51 - File not Found
Can't Save Configurations
App Crashes if User Chews Bubble Gum

Now, since the 1.15.1 upgrade, all that shows up is the following:

Extension:DynamicPageList (DPL), version 1.8.6 : <dpl_log_1>

Before you ask, no, there is no log being generated or updated anywhere within my wiki home that provides me with a clue as to why DPL isn't working.

I confess to being confused because when I originally downloaded DPL in May or June 2008, this was during the time frame that "old DPL" was known as "Intersection" and 'this' DPL was just known as "DPL", and at the time there wasn't even a reference to the forked versions on the extension page. (I only came to learn all of this with my research this past week.) However, I have verified that I am using semeb.com's Dynamic Page List (was using v.1.6.9, now using v.1.8.6.) I downloaded v.1.8.6 earlier in the week from http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/DynamicPageList/, and I just re-obtained the files from the ZIP archive available at http://semeb.com/dpldemo/images/f/fe/Semeb_extensions.zip and redeployed them to be certain. The behavior is still the same as above.

Any help would be appreciated.

== Parsing Pipes ==

I have run into a little bit of a quandary which I am trying to solve. I am trying to create a template with a set of parameters that are passed from a dynamically created list from DPL. However, when using the pipe character in the formatting for DPL like this:
<pre>{{Hot_issues
|<DPL>category=Application
category=Hot_issues
format=,|,[[%TITLE%]],
notnamespace=Category
noresultsheader=Nothing found...</DPL>}}
</pre>
...the pipe character is not parsed by the templating system, I think because of the order in which things are processed... The result is all the articles listed like this: "|Article1|Article2", and so on, instead of passing each one as a template parameter. I have been trying, but I can't think of a way around this. Does anybody have any thoughts on this? --[[User:Bsmithme|Bsmithme]] 21:12, 18 July 2009 (UTC)

<pre>Fatal error: Unsupported operand types in /home/schlott/public_html/wiki/includes/parser/LinkHolderArray.php on line 33</pre>
and the extension stoped working.

The solution was inside the DynamicPageList/DPL.php with the following statement in Line 36:
<pre>
// cloning the parser in the following statement leads in some cases to a php error in MW 1.15
// You must apply the following patch to avoid this:
// add in LinkHoldersArray.php at the beginning of function 'merge' the following code lines:
// if (!isset($this->interwikis)) {
// $this->internals = array();
// $this->interwikis = array();
// $this->size = 0;
// $this->parent = $other->parent;
// }
</pre>

After adding the mentioned code lines to LinkHoldersArray.php the extension works just fine. -- Flaming Moe

== Comment on differing versions by [[User:Algorithmix|Algorithmix]] ==
* Note that the version running on Wikimedia sites was at some point in time renamed to [[Extension:Intersection]] to avoid confusion with the extension described here. But the documentation still was talking of "DynamicPageList" and the SVN path was not renamed.
* Recently 'Intersection' claimed back its ancient name and that is why you now find the documentation of 'Intersection' under 'Extension:DynamicPageList'.
* On the other hand the DPL extension described here was still named 'DynamicPageList' and new functions were added. At some point in time downward compatibility with the version running on Wikimedia sites was lost. The extension was renamed to 'DynamicPageList2' but the documentation was still talking of "DynamicPageList".
* Then another bunch of functionality was added and downward compatibility (with DPL2) was lost. The name of this version was changed back to DPL (which was thought to be 'free').

''All this has created much confusion. Read below for a suggestion on how to re-unite the different variants.''

This extension '''Dynamic Page List (DPL)''' has the same roots as [[Extension:Intersection]]. Until recently DPL was almost - but not exactly - downwards compatible with ''Intersection''. A lot of confusion comes from the fact that ''Intersection'' uses the tag <DynamicPageList> whereas '''Dynamic Page List (DPL)''' uses the tag <DPL>.

DPL offers functionality '''that goes far beyond''' ''Intersection''. Some of this functionality might be useful also on Wikimedia sites. But the problem is that inexperienced users or people with 'not-so-good-intentions' might write DPL statements which create significant database load.

A good solution - which also puts an end to all naming ambiguities of ''DynamicPageList, DPL, DPL2'' and ''Intersection'' looks like this:
# There should be only ONE extension.
# It should be called ''DynamicPageList'' (short name DPL).
# It should listen to the tags ''DynamicPageList'' and ''DPL'' for compatibility reasons.
# Its sources should be in the mediawiki SVN
# It should be strictly downward compatible with ''Intersection''.
# It should offer a configuration switch (let us call it LevelOfFunctionality = LoF) which lets the administrator of a wiki decide, how much functionality will be offered to the users:
#* LoF = 0 is exactly identical with ''Intersection'' as of today.
#* LoF = 1 offers additional features which do not affect performance (mainly related to output formatting)
#* LoF = 2 offers additional features which are on the same conceptual level as ''Intersection'' like selection of pages by use of templates or by pagelinks. As the underlying table structures in the mediawiki database design are very similar to categories the performance cost of theses features are comparable in magnitude with ''Intersection'''s current features
#* LoF = 3 offers additional features which are more cost-intensive, like e.g. content transclusion from pages that occur in the DPL result; we think that a dedicated DPL cache could allow to offer these features also on high traffic sites - but this still has to be proved
#* LoF = 4 offers a last group of features which are a somewhat exotic and could create trouble if used by ignorant people (batch updates and batch deletions based on DPL query results)

DPL 1.8.0 made a huge step into that direction.

Please help testing! --[[User:Algorithmix|Algorithmix]] 21:10, 15 June 2009 (UTC)

:''Moved from the main page.'' [[User:GreenReaper|GreenReaper]] 20:02, 22 August 2009 (UTC)

:My own thoughts on this: it's a good idea, but performance is a huge consideration. I suggest investigating ways to avoid loading DPL code unless it is required, particularly [[Manual:$wgAutoloadClasses|$wgAutoloadClasses]]. Right now APC shows that it is touching all the code on every page access, and that's a significant cost when you have a large number of pages being accessed. [[User:GreenReaper|GreenReaper]] 21:51, 22 August 2009 (UTC)

::The latest version of DPL only loads a small portion of its php code on the initial require_once(). ONLY if there is a DPL call within a page the rest of the php code will be loaded. Which version did you test? [[User:Algorithmix|Algorithmix]] 05:53, 23 August 2009 (UTC)

:::Ah, indeed it does - thank you! I was using 1.8.6 and it seems you made that change in 1.8.7 - I updated to 1.8.8 and now only DPLSetup.php is showing up on each load. That is a big improvement in code loaded - from 1.1Mb to 150kb. :-) [[User:GreenReaper|GreenReaper]] 19:55, 23 August 2009 (UTC)

== Trying to List Pages... ==
Trying to List Pages within a Namespace in Category Mode, Alphabatized on a non category page. Sounds ridiculous however this is the syntax that i am using:
<pre><dpl>
namespace=Article
shownamespace=false
mode=category
ordermethod=category,title
</dpl></pre>
What i am trying to do is show all pages in the article namespace on a page in category mode alphabetized by the page title rather then the namespace. Currently all pages are organized under "A" because the pages are named Article:Page Name. I want to eliminate or mask the Article so that they are organized by Page Name.

Kevindank AT Gmail.com

:Hmh, you aren't very clear.
:1) is there really a custom namespace called "Article"? Cos otherwise you mean Main: "namespace="
:But I guess I know what you mean. Like in [http://semeb.com/dpldemo/index.php?title=User:Subfader/Olli1/O7 this example] you don't want U headings but 0-Z... I dunno a solution :/ --[[User:Subfader|Subfader]] 21:17, 21 October 2009 (UTC)

===Workaround ===
If you apply a very small patch you can use
ordermethod=titlewithoutnamespace
to get the desired result:

find (near line 1860 in DPLMain.php in the latest version)
case 'titlewithoutnamespace':
and add the following line immediately after that line:
$sSqlSortkey = ", $sPageTable.page_title ".$sOrderCollation." as sortkey";

I will add this code line to the next release.
In fact, the patch will make the new behaviour the default (which is o.k., I think). Use <tt>ordermethod=title</tt> to switch to the old behaviour.

This worked perfectly Thank You.

==DISPLAYTITLE and DYNAMIC PAGE LIST==
is it possible to tie this to DISPLAYTITLE to sort pages by their DisplayTitle?

==installation instruction problems==
Thanks for this powerful extension. In order to help others to use it, I want to report two problems I just had in following the installation instructions in the article.

The instructions say:
add include("$IP/extensions/DynamicPageList/DynamicPageList.php"); to LocalSettings.php
However, the actual file downloaded for v1.14 was named DynamicPageList2.php. This modification worked:
include("$IP/extensions/DynamicPageList/DynamicPageList2.php");

The second problem is probably due to my lack of familiarity with PHP. The instructions appear to say to add a function call in LocalSettings after the include() statement above to control the richness level, like this:
ExtDynamicPageList::setFunctionalRichness(3);
However, this caused a fatal error, so I commented it out. Should the call be like this?
DynamicPageList2::setFunctionalRichness(3);

== DPL extension inserts a blank line headline ==
[[Image:DPL empty line headline.jpg|thumb|right|450px|Blank line in headline]]
Problem:
DPL extension inserts a blank line in the article title (see picture). Other articles that do not use DPL, displayed without distortion.

I use the original Monobook skin and the following versions of components:
*MediaWiki - 1.15.0
*PHP - 5.2.8 (appache)
*MySQL - 5.1.30-community-log

Can you tell me how to solve the problem, please. Thanks!

== Having DPL Maintain #section Links ==

If the pages I'm building my DPL from have links like <tt><nowiki>[[#section|A Section]]</nowiki></tt>, is it possible to to have DPL maintain the url of the page with that specific section, rather than have it change it to the page that has the DPL on it? — [[User:Cosmotron|Cosmotron]] 18:56, 8 November 2009 (UTC)

== Template:DPL_Extension creation as potential redirect loop ==

There is a DPLSetup.php routine, commonSetup(), which attempts to create an <nowiki>{{Extension DPL}}</nowiki> template using the userid of the first user to visit the wiki after the extension is installed:

<source lang="php">
private static function commonSetup() {

if (!isset(self::$createdLinks)) {
self::$createdLinks=array(
'resetLinks'=> false, 'resetTemplates' => false,
'resetCategories' => false, 'resetImages' => false, 'resetdone' => false , 'elimdone' => false );
}

// make sure page "Template:Extension DPL" exists
$title = Title::newFromText('Template:Extension DPL');
global $wgUser;
if (!$title->exists() && $wgUser->isAllowed('edit')) {
$article = new Article($title);
$article->doEdit( "<noinclude>This page was automatically created. It serves as an anchor page for ".
"all '''[[Special:WhatLinksHere/Template:Extension_DPL|invocations]]''' ".
"of [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)].</noinclude>",
$title, EDIT_NEW | EDIT_FORCE_BOT );
die(header('Location: '.Title::newFromText('Template:Extension DPL')->getFullURL()));
}

}
</source>

Two issues with this:
* (minor) The external link [http://mediawiki.org/wiki/Extension:DynamicPageList Extension:DynamicPageList (DPL)] points to a disambiguation page here instead of to the actual extension info.
* (not so minor) If creation of the template fails, the user is redirected to [[Template:Extension DPL]] regardless, and the failed attempt to create the template is repeated until the browser detects this as a redirect loop and shuts down.

I've noticed that new installs, if started with just a blank set of database tables and a LocalSettings file (without running the MediaWiki installer again for the new wiki), are prone to go into an endless HTML redirect loop because of this code. Attempts to run maintenance/update.php from the command line may also abruptly end with errors if the extension is trying to create this page during the "update.php" run and the database is not yet updated to the latest MW format (and therefore not ready for the template creation attempt).

There needs to be some error handling; if the creation of the placeholder template fails, don't just keep trying forever - at least not if this is going to return errors or redirect loops. --[[User:Carlb|Carlb]] 14:12, 9 November 2009 (UTC)

== [SOLVED] White page after including Semantic Media Wiki Extension in LocalSettings.php ==

Hello,
I installed the Semantic Media Wiki extension on a Media Wiki 1.16.0
According to the install notes on the page I appended the following two lines to the LocalSettings.php:
 
include_once("$IP/extensions/SemanticMediaWiki/SemanticMediaWiki.php"); 
enableSemantics('filerepos.de'); 
 
After that I get a blank page on every URL of the Wiki.
Set error_reporting to E_ALL (in LocalSettings.php, SMW-Config-Files) but also got a blank page.

Also tried the hint from the Semantic Wiki Site with no success:

ini_set( 'memory_limit', '100M' );

When I comment the both lines out everything works again.

(Setup: Mediawiki 1.16.0, PHP Version 5.2.6, MySql 5.0.45, Semantic Media Wiki Extension 1.5.3 stable)

Would apreciate any hint.
:This page is only for support for the DynamicPageList extension. You're more likely to get a response if you ask the SMW people. With that said, Did you add the:
error_reporting(E_ALL);
ini_set("display_errors", 1);
as the very first lines of LocalSettings.php (directly below the opening <?php )? If that still doesn't work, try setting error reporting to E_ALL directly in your php.ini file. You can also try checking your webserver's error log as well (doesn't usually have php errors in it, but if its some sort of config problem with your webserver it might have relevant information). [[User:Bawolff|Bawolff]] 22:31, 26 November 2010 (UTC)

 
Thanks for the reply...think ini_set got the errorReporting working.
Now there is some output I can work with:
http://www.mediawiki.org/w/index.php?title=Extension_talk:DynamicPageList_(third-party)&action=edit&section=38
Call to undefined function enableSemantics() in /srv/www/vhosts/filerepos.de/httpdocs/websites/semwiki/LocalSettings.php on line 138

[SOLVED] I accidently downloaded the wiki and the extension with different user...so the wiki wasnt allowed to access the extension.
Changed extension files owner to the same owner as the wiki and so everything works now.
Thanks for the error reporting hint which allowed me to find my mistake

== Undefined index and .default ==

I try to make the DPL-Extension read out a category and get the parameters of a template in the articles of this category. They are meant to be used in another template. I saw another wiki which did it the same way as I did, but I get a strange Error while using the preview on this:

<pre><DPL>
category = Some Category
mode = userformat
includepage = {Template in articles} Kr
allowcachedresults = true
</DPL></pre>

"Notice: Undefined index: tip ... EditPage.php". The line is this: "$tip = $tool['tip'],".
This is strange but probably not that important. The real problem I got ist, that the extension always adds an ".default" at the end of the template. So I get a long list which just says "Template:Template in articles Kr.defaultTemplate:Template in articles Kr.default...".I don't really get the origin of the problem and couldn't find an answer anywhere.
I didn't change anything in the basic code of mediawiki, except for some extra buttons i added in EditPage.php. There are also no extensions, that could affect the DPL extension.--[[User:Eski123|Eski123]] 12:14, 2 January 2010 (UTC)

:My five cents on this: according to [http://semeb.com/dpldemo/index.php?title=Includepage#include_contents_related_to_templates doc], the DPL engine calls a template with the additional sufix ".default" when a page listed in the result does not use the specified template. [[User:Pierrem100|Pierrem100]] 14:49, 26 October 2010 (UTC)

== Problems with missing subheads ==

DPL is apparently crashing when used with a subhead that doesn't exist on one of the pages included by Category.

I have the following DPL code on a page called "Current projects":

=Projects in process=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects
|include = #Project steward, #Need
|includetrim=true
|table=class="sortable", Project, Steward, Need
}}

=Completed projects=
{{#dpl:
|ordermethod=lastedit
|order=descending
|category=Projects, completed
|include = #Project steward, #Final accounting
|includetrim=true
|table=class="sortable", Project, Steward, Final Accounting
}}

The first DPL call works if I temporarily clip out the second DPL cal, but including the second DPL call displays:

:Fatal error: Call to a member function getPrefixedDBkey() on a non-object in /Library/WebServer/EcoReality/wiki/includes/parser/Preprocessor_DOM.php on line 994

I then looked over the pages in the Category "Projects, completed" and discovered several of them did not have a subhead called "Final accounting." These are old pages, and this worked once upon a time!

For now, I've removed "Final accounting" from the second DPL call, but it seems it should behave better than this in such a case, no? Have I messed up something to cause it to misbehave this way?

See it fixed at: http://www.ecoreality.org/wiki/Current_projects .

== Spaces and underscores ==

It seems that the "titleregexp" parameter doesn't interpret spaces and underscores the same way. In fact, since page names can't have spaces in them, any time there is a space it just flat out fails. This would ordinarily not be such a big deal, so, okay, you learn not to use spaces, however i have a template for detecting direct subpages of a page (but not sub-subpages). the regexp is {{PAGENAME}}/[^/]*$ however, if used on a page with a space in the name, {{PAGENAME}} returns a space there where dpl requires an underscore. It seems to me that spaces and underscores should be totally interchangable in dpl, as they are in the rest of MW. [[User:DeFender1031|DeFender1031]] 11:22, 29 January 2010 (UTC)

A <nowiki><ref>asdf</ref></nowiki> reference won't show up in the <nowiki><references/></nowiki> section if any DPL query is run in between. Dug into the code a bit and it seems like DPL clones the parser and does a clearState(), maybe that clears the active cite object as well for some reason? Anyone else have this problem? Is there a workaround? I'm running MediaWiki 1.15.1, DPL 1.8.9 with PHP 5.2.6. --[[User:Shadowie|Shadowie]] 15:02, 27 February 2010 (UTC)

== Great and easy: Searchable Tables ==

I use the TableTools (Firefox-Extension) to search the tables generated with DynamicPageList (Mediawiki-Extension); see here [https://addons.mozilla.org/en-US/firefox/addon/2637]

With the Firefox-Extension installed you can right-click into a table and choose
# show Filter (german: Filter anzeigen)
# show Searchfilter (german: Suchfilter anzeigen)

With the first you get lists where you can choose an item in the table-heading and get all the rows matching this item.

With the second you get searchfields in the heading to use for a wildcard-search.

Both functions are very (!) usefull for the DynamicPageList-tables. But it is not userfriendly for less sophisticated users to right-click to get the function. I would like to put such functionality with an easy dpl-command into the heading, similar to the magicword "wikitable" or "sortable": "searchable". Now I wonder if it would be possible to integrate such a great feature directly into DynamicPageList??

I hope that others are also interested in such a feature.

== Setting parameter without using template? ==

Hi, it seems that all parameters are set in a template. In my wiki, there is a pretty standardized section and i would like to implement DPL on it. It's not a template but just a list of 1....2....3...list. Is there any markup tag that i can tell DPL that item01 = 1.. ; item02 = 2... ; item03 = 3.... ?

The current method is like this. It's actually good but in a FCKeditor-based Wiki, it may be too difficult to ask laymen to learn it.

== Image inside a template ==

Is there by chance a way to make a list of all of the images that are used in a template? For instance, on [http://runescape.wikia.com/wiki/Rune_scimitar this page], I'd like to have it add File:New Rune Scimitar.png . It's a parameter on the template, not part of the template itself. Is there a way to do so? [[Special:Contributions/24.41.43.85|24.41.43.85]] 06:19, 9 July 2010 (UTC)

== Parser function after a backup ==
I seem to have a strange issue after restoring a backup of my wiki on another computer. Both computers are using DPL version 1.8.9. I have a bunch of pages that use the parser function variant (<nowiki>{{#dpl: ...}}</nowiki> through some templates. For some reason, they display incorrectly on the new computer. Basically they just show the function then all of the parameters in what looks like a PRE tag.

The parser tag works fine. I can take the same queries and change them to the tag variant on a test page and they work great. The trouble is I need these to work in templates, so the function is needed. Anybody have any ideas what would cause this? - [[User:Glycerine102|Glycerine102]] 14:50, 19 July 2010 (UTC)
:No idea whats causing your original issue, but you can also try <nowiki>{{#tag:DPL</nowiki> - see [[Help:Magic_words#Miscellaneous]]. [[User:Bawolff|Bawolff]] 01:42, 20 July 2010 (UTC)

== Parser versus Hook change? ==

Does anyone know what might have changed in the code to cause the following statement to no longer include the category here, as seen below:

<code><nowiki>{{#dpl:category={{PAGENAME}}|category=Application Error|notcategory=Subtopic-topic|replaceintitle=/{{BASEPAGENAME}}\//,|format=,\n*,[[{{BASEPAGENAME}}/%TITLE%{{pipe}}%TITLE%]],|notnamespace=Category|noresultsheader=There are no symptom entries for this application.[[Category:Articles with no symptom entries]]}}</nowiki></code>

The odd thing is that it is actually working for one of my templates. I resolved the issue by converting to the <DPL> hook instead. Still, it seems strange that this suddenly stopped working. [[User:Thorncrag|Thorncrag]] 20:31, 18 August 2010 (UTC)
:And I have just discovered that my workaround will not suffice because using the hook causes replaceintitle to not function the same as when using the parser call instead. [[User:Thorncrag|Thorncrag]] 21:18, 18 August 2010 (UTC)
::Note, as said in the thread above this one, you can also use <nowiki>{{#tag:DPL</nowiki> to access the <DPL> tag as a parser function which should have the exact same behaviour as <DPL> (compared to <nowiki>{{#dpl:</nowiki> which has slightly different behaviour compared to <DPL>).

:I'm not sure what the number of 70760 is, however as far as i know they still play nicely together as long as the version of DPL is post [[rev:68812]]. However with that said, the categorylinks table changed quite a bit in 1.17 (aka current svn head). Some features might break in subtle (or perhaps not so subtle ways) because of that. It will certainly be less efficient for plain ole' category listings (but then again this is a very inefficient extension, so if you care about efficiently, I doubt you'd use it). Short answer: In my testing it still works, but no guarantees (+ the XSS issue). [[User:Bawolff|Bawolff]] 22:10, 13 September 2010 (UTC)

== DPL & Nested Templates? ==

I may be missing something so I am posting the question here. Can DPL query variables passed to a nested template? Meaning, ...
* You have a page named Resource1 which uses a template called ResourceType1 which is a member of the Asset Category.
* Within template ResourceType1 you pass variables to and call the template called AssetInfo.
* You then construct a DPL query which based on the Asset category queries all pages member of Asset and lists the variables found on the nested AssetInfo template

The rational for such a construct would be to list AsseInfo common to all resources which may use different ResourceType templates (type1, type2, etc) but are all members of Asset. Since the include/includepage line in DPL table output must be consistent, querying the nested common template seems the best approach but does not work.
please advise?, thanks ahead of time for replies [[Special:Contributions/208.79.244.111|208.79.244.111]] 23:23, 4 October 2010 (UTC)

== Replace in title breaks with titles that contain parentheses ==

I've just discovered that an article title which contains parentheses causes the replaceintitle statement to break in that it will no longer perform any longer. In context, I have a replaceintitle which is supposed to remove the BASEPAGENAME from the title or an article that is a subpage, so that when I output title I can output only the name of the subpage instead of the entire trail. I still need to do further troubleshooting to see if it is actually BASEPAGENAME or %TITLE% which is breaking. Nevertheless, it's clearly an issue with the extension. [[User:Thorncrag|   Thorncrag  ]] 22:41, 7 October 2010 (UTC)
:Note, per issue I reported above, I changed to #tag:DPL .... which is what bawolff had suggested. Unfortunately I misread it a long time ago... Anyhow that seems to have sufficiently worked around this issue. [[User:Thorncrag|   Thorncrag  ]] 23:30, 7 October 2010 (UTC)

:::<nowiki>{{#tag:DPL</nowiki> Should take the exact same syntax as <DPL>. If there's something that works for <DPL> but not <nowiki>{{#tag:DPL</nowiki>, that's probably a bug in mediawiki (core) not the extension, since converting <nowiki>{{#tag:DPL</nowiki> to <DPL> is part of the parser. (With that said, I'm not sure how it'd help you with your issue, since the two should be exactly the same with exception of parsing the args before passing to DPL.).

== Use with TreeAndMenu Extension ? ==

Hi,

I only need this:

{{#dpl:category=Foo|format=,**,[[%PAGE%]]\n,}}

..To dynamically add all pages to a tree that is created by the Extension TreeAndMenu.
I´ve tested it and it works great. Though I´m planning an opened wiki I´m a bit scared
about the red box on this extensions main page telling me that it has a major security
risk.

Is it possible to enable this extension only for a specific (admin) page or to eliminate
the security risk by adding some contraints?

Thanks in advance!

== Tree and Menu and DPL - Advanced use ==

I'm currently using Tree and Menu and DPL to generate lists as shown in the Example. Works fine.

{{#tree:id=ToolsMenuTree|openlevels=0|root=Tools, Tips and best practice|
* [[Tools and Tricks|Overview]] (Introduction Page)
{{#dpl:category=Tools and Tricks|format=,**,[[%PAGE%]]\n,}}
}}

The problem is that our wiki will have a lot of pages and subpages, making the list expand really fast with similar named entries such as:
Outlook
Outlook/Installation
Outlook/Usage

With the example structure above, is there a way to automatically create subfolders for all subpages using DPL syntax? Should be looking something like that
**Outlook
***Installation
***Usage
Any hints would be greatly appreciated. (Mike)

== Breaks when using ordermethod pagesel ==

I've run into an interesting problem. When attempting to generate a list using "linksfrom" and setting ordermethod to "pagesel", the parser breaks with the following error:
<pre>SELECT DISTINCT `page`.page_namespace as page_namespace,`page`.page_title as page_title,`page`.page_id as page_id, pagesrc.page_title as sel_title, pagesrc.page_namespace as sel_ns, CONCAT(pl.pl_namespace,pl.pl_title) AS sortkey FROM `pagelinks` as plf, `page`as pagesrc, `page` WHERE 1=1 AND `page`.page_is_redirect=0 AND `page`.page_namespace = plf.pl_namespace AND `page`.page_title = plf.pl_title AND pagesrc.page_id=plf.pl_from AND ((plf.pl_from=0)) ORDER BY sortkey ASC LIMIT 0, 500

Error message is:
Unknown column 'pl.pl_namespace' in 'field list' (localhost) </pre>
What's interesting is that this error does NOT occur if I change "linksfrom" to "linksto". What's also interesting is that on a cursory check of DPLMain.php for malformed code and found that the column pl.pl_namespace isn't even referenced in the "linksfrom" section, but is referenced in the "linksto" section, but I may not be looking at it right.

== Show images of a category including links to pages using these images! ==

Hi all,

I have a difficult question. I would like to create a gallery like that:

{{#dpl:
|category=Oneofmycats
|namespace=Image
|format=«gallery»,%PAGE%¦%NR%. %TITLE%\n,,«/gallery»
}}

That works great. But now I would like to have the name of the page (all of my images are at least only used on one page!) which makes use of the image as image text (not TITLE). In addition to that the name of the page should be a linkt to the page! So it would be possible to show all Images of a certain category including linkt to each page using this image (there is only one page!).

Found this code here:

{{#dpl:
|imageused=myimage.jpg
|format=,[[%PAGE%]]\n,,
}}

But I don´t know how to merge this two operations to one big thing!

Hope you understand what I mean :-).

Thanks in advance.

== DPL for category page – order by second name? ==

I'm using DPL for a personalized category page because I didn't like the MediaWiki-own view. Everything works fine but there is one point I despair of. For the category of persons I want the list to be ordered by second name. In the standard category view this issue is solved by a tag on every page that tells MediaWiki how to order, e.g. on the page "Angie Gielach" <nowiki>[[Kategorie:Personen|Gielach]]</nowiki> to have it listed under "G" instead of "A".

In DPL I use the following code to display the pages of my category "Personen" alphabetically:

<pre><nowiki>
===A===
<DPL>
category = Personen
format = ,\n* [[%PAGE%|%TITLE%]],,
title<=B
</DPL>
</nowiki></pre>

Has anyone a solution for this?

== Question about "includematch" ==

I use this great extensions in two of mine wikis. In the last times, i have some problems with includematch.
My Wiki is about Final Fantasy XIV Online, for info ;)

NPCs are selling some Items, the item goes in the category:example sells from NPC.
Now, some NPCs sells example-head, examplefeed, example-earring. If i create now the Article examlpe,
i use this DPL:
<pre>
{{#dpl:
|category = {{SUBPAGENAME}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{fixapos|{{fixtick|{{fixparen|{{SUBPAGENAME}}}}}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

Here i use the _Template:Sellsrow to get the Price and the Template:NPC dpl Zones to get all other datas.
In the Template:Sellsrow, i define '''Item'''. Thats why my includematch say get where Item = <nowiki>{{SUBPAGENAME}}</nowiki>.
So, my Articles shows me now in the Table all sellinginformations about:
*example
*example-head
*examplefeed
*example-earring

i try'd some other includematch variations like this:
<pre>
{{#dpl:
|category = {{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}} sells from NPC
|namespace =
|includepage = {Sellsrow}:Price, {NPC} dpl Zones
|includematch = /\s*Item\s*{{=}}\s*{{#if: {{{Name|}}}|{{{Name|}}}|{{PAGENAME}}}}/si
|format =,,\n
|table =class="SE-Heaventable sortable" style="width: 100%;",Name,Preis,Region
|columns=1
|rowcolformat= style="background-color: transparent; width: 100%;"
|tablerow = %%,%%
|suppresserrors=true
}}
</pre>

but at least, i have allways the Same problem. It shows me all what that NPC have, where example is in :\
The only what i want to see, is the Data for example >.< Someone knows how i can fix it? [[User:Yukii|Yukii]] 12:52, 17 October 2011 (UTC)

::I'm not quite sure I understood everything you said, so in case you want to clarify, you can tell me in German. // Ich bin mir nicht ganz sicher, dass ich alles richtig verstanden habe, und falls nicht, dann kannst du es gerne auf Deutsch nochmals erklären.
::The problem is, as far as I can see, that you never included the line "Item=..." in your DPL call; you only called to include "Price=..." parameter in the {Sellsrow} template. The includematch function works only, if you include the respective parameter, so in order for it to work, you need to change <code>{Sellsrow}:Price</code> to <code>{Sellsrow}:Item:Price</code>. --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 13:43, 22 March 2012 (UTC)

== Warning about $maxResultCount ==

Just as a heads-up, <code>$maxResultCount</code> is '''not''' a limit on DPL's results, but a limit on the amount of rows pulled from the database. '''That is not the same thing'''. For example, the DPL query...

<DPL>
includematch=/\|\stemplate-attribute\s=\svalue/s
titlematch=Foo%
category=Foos
</DPL>

...will '''first pull all pages beginning with "<code>Foo</code>" in the category "<code>Foos</code>" from the database''', and only '''then''' check for the <code>includematch</code> pattern. In other words, if <code>$maxResultCount</code> is 500 and you have 800 <code>Foo%</code> pages in the <code>Foos</code> category, '''''even if just ten of those match your <code>includematch</code> pattern, you will probably not get all ten'''''.

Our solution was to remove the limit entirely (<code>$allowUnlimitedResults = true</code>), because our wiki is private and we have a strong control over authorship.

Your mileage may, of course, vary. -[[User:Pinkgothic|pinkgothic]] 13:32, 30 November 2011 (UTC)

== Null edits (or dummy edits) required for updating DPL listing ==

The wiki I administer makes a huge use of DPLs for constructing lists of pages and controlling workflows--very well might I add.

One problem that I have perennially run into however is the need to execute a null edit in order for pages to properly show up in a DPL when the DPL is grabbing based on, for instance, page category. What I don't understand is that when accessing the page in question the category is correct, but the DPL listing the page will not include the page in its list until executing a null edit on the page. I'm fairly knowledgebale about this extension but I have not come up with a solution to this problem. I've even tried using updaterules to "touch" the page when the list is built, but that feature does not seem to be usable at this point.

Since the page shows the correct category, and the job queue is empty, I can't actually figure out why this is happening. The only thing that I can think of is that the DPL is stored in a cache; however, that should not be causing this since cached results are supposed to be disabled by default. I do have MediaWiki parser cache set to enabled as well as file cache, but disabling these seems to have no effect on the symptom. Any thoughts on this? [[User:Thorncrag|   Thorncrag  ]] 18:40, 12 January 2012 (UTC)

:I may have posted too soon; I ''completely'' disabled caching across the wiki and this seems to have resolved the problem altogether. This works for now, although from a scalability perspective I'm not sure. [[User:Thorncrag|   Thorncrag  ]] 19:20, 12 January 2012 (UTC)

::I think I posted too soon again. I think disabling cache only caused an update, but null edits are still required. I can't seem to find a way around this. [[User:Thorncrag|   Thorncrag  ]] 16:39, 1 February 2012 (UTC)

== "skipthispage" - not bolded when created by DPL ==

Hi! I'm working through the book MediaWiki and Beyond. Great book, but I've run into something that doesn't seem to be working. In the book it says that if you use the 'skipthispage' variable and set it to false, not only will the page you are on show up in your list (in this case a navigation list), but since its pointing to itself, it will default to bolded text rather than a link. I don't seem to be able to get that behavior though. If I put a link to the page within itself, that will bold and present just as text, but not when it comes through the dpl command. Any ideas why?

== DynamicPageList only works with global $wgRawHtml set to true. ==

Between MediaWiki version 1.15 and 1.16 the way the < html > tag is handled changed. As a result, the DynamicPageList extension's abuse of the global $wgRawHtml setting to temporarily enable raw HTML content is broken. The normal way (to my knowledge) for an extension developer to embed raw HTML is to create one or more markers and then to post process the content and replace the markers with HTML after MediaWiki has done all of it's HTML stripping.

== Attempting to use DPL to create a table "on-the-fly" on any given article page by pulling from a list on a page; Getting error message: %DPL-1.7.6-WARNING: No results! ==
* Hi, so my goal in this scenario is to create a table on-the-fly using DPL and put that table on any given article page (I've opted to do a template call to facilitate this) -- and so part of the problem has been to figure out which of the DPL commands are best suited to accomplish this. I started with table and tablerow and initially got the results I was looking for on simpler test examples. But now I'm getting this error %DPL-1.7.6-WARNING: No results! and I can't find my bug! So yesterday I started looking at the secseparators and multisecseparators commands, but the syntax is killing me and they're just a bit too tricky for me right now (I just started learning/implementing DPL). In the DPL Manual it even suggests sticking with "table" and "tablerow", and that's what I'd like to do.
* I'd be grateful for some help figuring out where I took a wrong turn.
* One thing I saw yesterday was that I had misnamed the first parameter - i.e., Drug Code instead of Pfizer Drug Code. So I corrected that. It still didn't work. So I created a new Template:Drug Info 5 and Template:Drug Info5.dpl - suspecting that maybe there was something I wasn't aware of in the functioning of a phantom template where even if I fixed the parameter name in the dpl template, the phantom template might not pass the parameters through properly (?).
* Further down I list an example that did work. That's the one I built upon to try to get this one to work.
* Many thanks for your reply and insight. Cheers, Jeff Western cell: 323.449.7944

:Hi, could you give me a link to your wiki and the respective pages, so I can take a look at it? --[[User:Theaitetos|Theaitetos]] ([[User talk:Theaitetos|talk]]) 23:24, 4 July 2012 (UTC)

::7/5/12:
::Hello, I wish I could give you a link to the wiki, but it's an internal wiki to the company and a network credentials are required in order to even view the wiki. Good news is that the solution to this first part of my problem is to use <tt>titlematch=</tt> in the DPL, not <tt>linksto=</tt>. I admit, I really didn't quite understand how the linksto command works, but titlematch definitely worked.
<pre>

::I'm currently trying to figure out how to use the output of this table to enable the end-user to pick a drug (a row of Drug Info data) and copy that row and only that row to a new table in another section of the same page. I was going to upload an image here so you could see what the table looks like, and where I'm trying to get to... but I don't see an <tt>Upload</tt> link here.
::I appreciate your having looked at my questions, in any case. Thank you!
:::You could upload files via [[Special:Upload]], but I recommend uploading to an image hoster like http://tinypic.com or something similar.
:::I am still a bit unsure what you mean with copying that code to the same page. Are you trying to create a table, or code for a table that can be copied and pasted?
:::The tablerow in the latest statement shouldn't do anything as the entire output of a phantom template should not be changed by tablerow.
:::The linksto statement is selecting pages basically the same way as the "what links here"-tool.
:::The way you use the titlematch statement should only give you one page, the very one you put into the statement. If you want to select several pages with titematch, you will have to use "_" as a one letter wildcard or "%" as a wildcard for any amount of letters; for example "titlematch=c_t" would give you "cat", "cut", et.al. yet "c%t" could even give you "cannot", "carrot", ...

::Theaitetos, I much appreciate your looking at this and answering with this code. I just tried it and it works. I got my code with the phantom template to work as well, but yours is a bit cleaner of course. I do get some multiple hits on a couple of the drugs, not sure why, but I suspect it might be my error somewhere (maybe too many category tags?!); I also got multiple hits with my code.
::(7/12/12)'''''On another note, the last piece of the puzzle for this first User Story that I'm trying to solve right now is this...''''' '''Once the user is on a Disease page, how do I "automate" (from the user's pov) the selection of drug(s) that they wish to associate with the disease?''' (...which then leads to the creation of the on-the-fly-dpl-table, which is pretty much working now -- thanks again!) So, I've checked with the internal IT dept here, and Javascript drop-menus are out of the question -- too bad, seems that's the nicest way to implement this. Raw HTML is not allowed currently on the company's internal wiki (and discouraged in general), and Javascript is only allowed by changing Common.js – which is a javascript which is triggered on every page load on the wiki. So they're telling me it's very inefficient to include Javascript on their internal wiki. Okay, so the approach I just hit on yesterday (brainstorming in my head while smoking a cigar!) is to do the following:
* Created a template: <nowiki>{{DPL for EQDD Diseases List with include redirects}}</nowiki>
* This template has DPL: <nowiki>{{#dpl: |category=EQDD Diseases List |mode=none |redirects=include |format=,\n* EQDD for [[%PAGE%|%TITLE%]],, }}</nowiki>
* Then I do the template call on any Disease page where I need it and it works, producing:
:::EQDD for Age Related Macular Degeneration
:::EQDD for Allergy and Respiratory
:::EQDD for Asthma
:::EQDD for Bunionectomy
:::EQDD for Chronic Abacterial Prostatitis
:::EQDD for Crohn's Disease
:::EQDD for Crohn’s Disease
:::EQDD for Dental Pain
:::EQDD for Discoid Lupus
:::EQDD for Endometriosis
:::EQDD for Inflammation
:::EQDD for Lupus
:::EQDD for Lupus Nephritis
:::EQDD for Male Erectile Dysfunction (MED)
:::EQDD for Ophthalmology
:::EQDD for Pain
:::EQDD for Primary Dysmenorrhea
:::EQDD for Systemic Lupus Erythamatosus (SLE)
:::EQDD for Ulcerative Colitis
:::EQDD for Women's Health and Urology
*'''But here's is where I run into a stumbling block...''' '''''I've discovered that when I try to run the subst: command on dpl, I just can't get it to substitute the straight text for me, e.g., <nowiki>{{subst:{{DPL for EQDD Diseases List with include redirects}} }}</nowiki>. What it does is always gives me the dpl in the substitution. What I need''' '''''I think!''''' '''is the straight text so that I can manipulate it. Because clearly, one cannot manipulate the output from a template call, or DPL, as it is just for viewing, right. So unless there is a way, using DPL commands, to further manipulate the data (on-the-fly by the DPL) such that a user can somehow select one of the diseases (list above) -- then I don't see any other way to do this. I suppose they could just highlight the text in the page name (from the list above), copy it, and paste it into a link on that Drug page, e.g., <nowiki>[[EQDD for Ulcerative Colitis]]</nowiki>
*''''' You see, what I'm trying to do is a work-around to not having a drop-down menu option for folks to be able to select from a list of already existing Disease pages. This way, they cannot possibly enter the name of the Disease page incorrectly. So what I'm trying to do is figure out a way to take a Disease page name (exactly as you see them listed above) and turn that page name into a <nowiki>[[link]]</nowiki> on the drug page -- thus the association between the drug and the disease. Then I use the linksto= command, and I get a listing of just the drugs that have been selected and associated with a disease, displayed by the on-the-fly-dpl-table on the Disease page. Again, any suggestions would be greatly appreciated. Thank you.

:*As far as javascript is concerned: There should be some javascripts coded into the core Mediawiki css anyway, so you could try to use that stuff to do some drop-down menus. For example, try to see if the following table works in your wiki:
::* Thank you for this great suggestion! This would be a terrific solution but unfortunately it doesn't run on the company's internal wiki. I'm thinking they don't have any Javascript enabled..? When I put this table into the internal wiki, it builds a table just fine, but it's not interactive (won't expand, collapse) like it does here.

:*As for the substitution: You have to substitute a dpl-call by adding the "subst:" into the dpl-call, i.e.: <code><nowiki>{{subst:#dpl:</nowiki></code>
::* That's ''AWESOME!'' Thank you -- just tried it and it works great! You see, what I'm after is implementing a User Story where the goal is associate a drug with a disease and in order to do this, I must ensure the end-user cannot enter a link incorrectly... ergo my interest in drop-down menus! Shame they won't work on this company's wiki. Anyway, so my work-around is to grab all the disease pages (they're tagged by Category of course) and then wrap <code>[[..]]</code> square brackets around the disease page name (article name) and then instruct the end-user to copy that text exactly (with the brackets) and paste it into the Drug page. So that creates the link, which <code>linksto=</code> then uses to pull up only those Drug pages that have been ''associated'' with a particular Disease page. Of course down the road, it would be nicer to have that <code><nowiki>[[link]]</nowiki></code> get inserted in a more automated fashion -- to avoid any possibility of the user making a mistake.
:*It's hard to imagine what output you specifically desire without looking at it. Could you put one example down here, so I can see it? I.e. the direct output you desire, no dpl anything, just how you want it to look like and I'll see if I can find the proper code to produce said output.
::*Yes, I can appreciate that. That's why I wear multiple hats on this job - Business Analyst, to understand their needs and document requirements - Developer, to implement the User Stories - and PM to hopefully make all this happen in time. So next week I'm going to set about updating my User Story diagrams and I'll start with this user story, and I'll list it here for you to see. Again, many many thanks for your great suggestions. It's been a hard week -- what with going down blind alleys with subst: -- and your hint will I think get me there!
:*About having multiple results: You can disable multiple results by adding the parameter <code><nowiki>distinct = strict</nowiki></code> to your dpl call.

:''This is a third-party extension, not to be confused with the [[Extension:DynamicPageList (Wikimedia)|DynamicPageList used on Wikimedia sites]].''

 

'''DynamicPageList''' (DPL) is a reporting tool for MediaWiki, listing category members and intersections with various formats and details. For full documentation, see the [http://semeb.com/dpldemo/DPL:Manual manual] (German Manual [http://www.wiki-aventurica.de/wiki/Hilfe:Dynamic_Page_List Hilfe:DynamicPageList]).

In its most basic form, DPL displays a list of pages in one or more categories. Selections may also be based on factors such as author, namespace, date, name pattern, usage of templates or references to other articles. Output takes a variety of forms, some of which incorporate elements of selected articles.

This extension is invoked with the parser function <code>{{#dpl: .... }}</code> or parser tag <code><DPL></code>. A [[Extension:DynamicPageList (Wikimedia)|Wikimedia]]-compatible implementation of certain features can be invoked with <code><DynamicPageList></code>.

DPL can result in computationally-expensive database queries. For best performance, use the optional parameters [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#allowcachedresults allowcachedresults] and/or [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] where possible.

== Installation ==
The extended dynamic page list (DPL) is now in Wikimedia's SVN. To install:
* download [[Special:ExtensionDistributor/DynamicPageList|the extension files for your version of MediaWiki]], and place them in the <code>extensions/DynamicPageList</code> directory
* add <code>include("$IP/extensions/DynamicPageList/DynamicPageList2.php");</code> to LocalSettings.php
* set overrides for DPL configuration variables, if desired
LocalSettings.php must '''not''' include [[Extension:Intersection|Wikimedia's version of DPL]] (Intersection). If you want to run them in parallel, [http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/DynamicPageList/DynamicPageListMigration.php?view=markup include DynamicPageListMigration.php instead] to prevent this extension from overriding <code><DynamicPageList></code>.
===Configuration===

DPL configuration settings and their default values, '''[http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_Source_and_Installation#Server-Wide_Configuration:_Extension_options from the manual]''':
::{|
|<code>ExtDynamicPageList::$maxCategoryCount</code> || ''?''
|----
|<code>ExtDynamicPageList::$allowUnlimitedCategories</code> || ''?''
|----
|<code>ExtDynamicPageList::$minCategoryCount</code> || ''?''
|----
|<code>ExtDynamicPageList::$maxResultCount</code> || 500
|----
|<code>ExtDynamicPageList::$allowUnlimitedResults</code> || <code>false</code>
|----
|<code>ExtDynamicPageList::$categoryStyleListCutoff</code> || ''?''
|----
|<code>ExtDynamicPageList::$respectParserCache</code> || <code>false</code> for <dpl> but <code>true</code> for <DynamicPageList>. If set to 'true' DPL will no longer behave dynamically because its output is taken from the ParserCache.
|----
|<code>ExtDynamicPageList::$options</code> || ''no options''
|----
|<code>ExtDynamicPageList::setFunctionalRichness($level)</code> || 4 ''''
|-
|colspan=2|
|}
The global variable {{manual|$wgNonincludableNamespaces}} is also respected by DPL. It will prevent the contents of the listed namespaces from appearing in DPL's output.

'''Note: <code>$maxResultCount</code> is a LIMIT ''on the SQL query itself''. Some DPL query parameters like <code>includematch</code> are applied ''after'' the SQL query, however, so results here may easily be misleading.'''

==== Functional richness ====

DynamicPageList has many features; some are expensive, or dangerous in the wrong hands. It is important to choose an appropriate level of functionality for your wiki.

* <code>ExtDynamicPageList::setFunctionalRichness(0)</code> is equivalent to Wikimedia's DPL
* <code>ExtDynamicPageList::setFunctionalRichness(1)</code> adds additional formatting parameters
* <code>ExtDynamicPageList::setFunctionalRichness(2)</code> adds performance equivalent features for templates and pagelinks
* <code>ExtDynamicPageList::setFunctionalRichness(3)</code> allows more-expensive page inclusion features and regular expression queries; expect to use the [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] parameter
* <code>ExtDynamicPageList::setFunctionalRichness(4)</code> permits exotic and potentially dangerous batch update and delete operations; not recommended for public websites

'''Note: Functional Richness parameters have been removed in the latest versions of the extension. There is no function for setting functional richness in these versions.'''

==Use==
===Extended DPL functionality===
Extended DPL is invoked by using the parser function <code>{{#dpl: .... }}</code>, or the parser extension tag <code><DPL> .... </DPL></code>.

:''See: [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_General_Usage_and_Invocation_Syntax Manual - General Usage and Invocation Syntax] and [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Criteria_for_page_selection Manual - '''DPL parameters''']''

=== Backwards-compatible functionality ===
Functionality compatible with Wikimedia's DPL extension can be invoked with <code><DynamicPageList> .... </DynamicPageList></code>.
:''See: [[Extension:DynamicPageList (Wikimedia)#Use]]''

==Overview==
Assume you have written some articles about ''countries''. Typically these articles will have three things in common:
* They will belong to a common category
* They will have a similar chapter structure, i.e. they will contain paragraphs named 'Religion' or 'History'
* They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

===DPL generates reports on articles===
Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on the countries.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

With DPL you can ..

* generate a list of all those articles (or a random sample)
* show metadata of the articles (popularity, date of last update, ..)
* show one or more chapters of the articles ('transclude' content)
* show parameter values which are passed to the common template
* order articles appropriately
* present the result in a sortable table (e.g.)
* use multi column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* select by a logical combination (AND,OR,NOT) of categories
* specify a range for the number of categories the article must be assigned to
* select by a logical combination (AND,OR,NOT) of namespaces
* define a pattern which must match the article´s name
* name a page to which the article must or must not refer
* name a template which the article must or must not use
* name a text pattern which must occur within external links from a page
* exclude or include redirections
* restrict your search to stable pages or quality pages ("flagged revisions")
* use other criteria for selection like author, date of last change etc.
* define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* name
* date of last change
* popularity
* user who changed them last
* size
* restrict the output to the first n articles or to a random sample
* use descending or ascending sequence

'''Define attributes you want to see'''
* article name
* article namespace
* article size
* date of last change
* date of last access
* user who changed them last

'''Define contents you want to show'''
* whole article
* contents of certain chapters (identified by headings)
* text portions (defined by special marker tags in the article)
* values of template calls
* substitute the original template by a different one and show the output of that template

'''Define the output format'''
* specify headline and footer for your report
* use ordered list, unordered list
* use tables, sorted tables (using javascript)
* format table fields individually by applying templates to their content
* use category style listing
* create "tag clouds" by varying output text size depending on popularity of pages
* multi column output
* truncate title or contents to a certain maximum length
* add a link to the article or to one or more of its chapters

===DPL generates reports on categories===
Apart from producing a list of pages which match certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

===DPL can be used for bulk editing===
Sometimes you want to perform a similar editing task on many articles (like adding a template at the beginning of the text). DPL has a feature which allows you to update other articles based on regular expressions. This feature is experimental and can be disabled in the DPL config file.

===DPL extracts objects and relations for generation of graphs with [[Extension:Wgraph]]===
With DPL you can generate output which is then fed into other MediaWiki extensions. An especially useful application of this kind is graph generation. DPL can analyze your wiki and prepare output which is then used by [[Extension:Wgraph]] to visualize it.

===DPL interacts with other extensions===
There is a special mechanism which allows you to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can generate nice bar graphs or pie charts using DPL together with ''Ploticus'', you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a light-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

===DPL and performance===
With a few lines of DPL code it is possible to create huge output and CPU load (think of a DPL query which tries to include the contents of all articles in your mediawiki ;-)). Normally this is not a problem because users who write DPL queries have some level of expertise. If you are afraid, however, you can restrict the execution of DPL queries to ''protected articles''.

Apart from that the general performance of DPL on medium-size wikis is quite acceptable (see the performance tests on the dpldemo website). Use of [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#allowcachedresults allowcachedresults] and/or [http://semeb.com/dpldemo/index.php?title=DPL:Manual_-_DPL_parameters:_Other_parameters#dplcache dplcache] where possible can improve performance.

==MediaWiki SVN Version of DPL2==
The instructions on this page were written for the code that is available from http://semeb.com/dpldemo/Download and is different than the version available in MediaWiki's SVN. Some of the differences include:
* There is not a <DynamicPageList> tag, just a DPL and section tag.
* There is no setFunctionalRichness() function.
* The main class is named ExtDynamicPageList2 and not ExtDynamicPageList.

==See also==
===Further reading===
DPL can do much more than we can explain here. A complete '''[http://semeb.com/dpldemo/DPL:Manual manual]''' and many examples can be found on the on the separate [http://semeb.com/dpldemo DPL website].

===''Call'' extension===
The website where DPL is offered for download also contains the ''Call'' extension which allows to call an arbitrary MediaWiki article from the command line or from a wiki link and pass parameters to that article at the same time.

===Other applications===
* [[DPL Page Name S/N Maker]]-Use this extension to create pages with serial number page names

=== Comparisons ===
* [[Comparison of Dynamic Pagelist x Semantic Mediawiki]]

===Related extensions===
* [[Extension:BackLinksFunctions|BackLinksFunctions]] counts backlinks
* [[Extension:News|News]] creates reports on page changes
* [[Semantic MediaWiki]] turns links and data in wiki pages into queryable information
* [[Extension:TemplateTable|TemplateTable]] creates tables from template fields
* [[Extension:Ploticus|Ploticus]] can be used to create charts from DPL query results

* [[Extension:Todo Tasks]] creates/maintains todo tasks and notifies users to whom the task is assigned
* [[Extension:DPL Calendar]] a highly configurable calendar
* [[Extension:CategoryLink]] Creates a table of the wiki's categories

===Older versions of this extension===
* [[Extension:DynamicPageList2]] (older version)
* [[Extension:DynamicPageList (Wikimedia)]] (the one used on Wikinews and Wikibooks. Note this extension is a fork of the other extension, and not exactly an older version)

You offered to demonstrate my extensions on the DPLDEMO website. This would indeed be very interesting. Feel free to install the extensions, and I'd be happy to write some demo code!

You might prefer not to enable [[Extension:StackFunctions#Database_Querying|Database Querying]] as this implies that the email adresses of registered users become publically available. Unfortunately I don't know how to solve that, and to my opinion this is a serious obstacle against using Database Querying on public sites.

Nevertheless, even without that feature [[Extension:StackFunctions]] still offers a lot of posibilities which would be worthwhile to demonstrate. - [[User:RV1971|RV1971]] 09:29, 26 May 2007 (UTC)

My name is Michael Stahnke and I work with the Fedora project. We'd like to package up some of your mediawiki extensions as RPMs for use with our distribution. Currently, however we are unclear on the licensing of these extensions. They only say 'no license specified' on the mediawiki.org extension page, and examining the source code has not helped either. If these are in fact open source extensions, please place a license on them so we are free to use them in our distribution. Until the license is clarified, we are unable to include them in our distribution.

==Question on GPL license version number ==
I was referred to you as the developer of the Dynamic Page List extension. I am currently using your DPL (Dynamic Page List) extension to MediaWiki. I checked around on various links and I found that it is available under the GPL license but it there is no specification of which version: GPL v2 or GPL v3.
Do you know which GPL version the DPL extension is licensed under? I can use products licensed under GPL v2 but not GPL v3. If it is GPL v3, is it possible to get a version licensed under GPL v2?

Thank you for your assistance.

== Extension:DynamicPageList_(third-party) ==

Hi, you add a warning to this extension. Can you please explain what the risk means for sites with this extension? I want to know if I shall uninstall it or that I can still use it. Thanks for your answer. [[Special:Contributions/145.94.74.23|145.94.74.23]] 15:20, 17 July 2010 (UTC)
:Hi. Basically the warning means that someone with knowledge of the insides of that extension would be able to inject html (including javascript) into your page if you have the extension enabled. Someone could potentially exploit this to put a code in the wikipage to make anyone who views that wikipage make edits to some other page for example. Another example is someone could put code into a wikipage that causes everyone who views that page to be redirected to another website. The most recent version of the extension is slightly harder to exploit, but someone familiar with the internals of that extension could still exploit it. See also [[wikipedia:Cross-site_scripting#Persistent]] and [[bugzilla:24199]]. As a side note, if you're only using the basic features of the extension, you could try using [[extension:DynamicPageList (Wikimedia)]] which does not have the above mentioned security issues but has significantly less features. [[User:Bawolff|Bawolff]] 15:50, 17 July 2010 (UTC)
::Thanks for the explanation. One more question: Does someone need to log in and be able to edit pages on the site to use this exploit? Or is it something that can be used without any rights? [[Special:Contributions/145.94.74.23|145.94.74.23]] 15:20, 18 July 2010 (UTC)
:::Yes, one would need to be able to edit. Basically the exploit is that someone can use the dpl extension to make part of the page behave as if [[manual:$wgRawHtml]] was set to true. Thus, all the warnings that apply to that setting also apply to that extension. If its a private wiki and you trust everyone who has access, you should be fine.

Hello Bawolff, I saw that you are concerned about DPL regarding security (HTML injection). I plan to work on a major new DPL releasse in January 2011. Currently DPL switches silently to allow HTML for internal purpose and switches back once it has finished. A user knowing this might inject HTML code or even Javascript as cou clearly explained. I plan to restructure the code and to avoid such risks (at least in a default configuration setting). Would you be willing to review or maybe give some advice when I start working on the changes?

Leider habe ich beruflich nicht mehr mit MediaWiki zu tun, sonst wäre dir eine Installation sicher :) Gruß, --[[User:Flominator|Flominator]] 13:56, 27 December 2009 (UTC)

== Comparison of Dynamic Pagelist x Semantic Mediawiki ==
I have startet a "Comparison of Dynamic Pagelist x Semantic Mediawiki".
Please help to improve the comparison and add some information: [http://www.mediawiki.org/wiki/Comparison_of_Dynamic_Pagelist_x_Semantic_Mediawiki Comparison of Dynamic Pagelist x Semantic Mediawiki]

==Question on GPL license version number ==
I was referred to you as the developer of the Dynamic Page List extension. I am currently using your DPL (Dynamic Page List) extension to MediaWiki. I checked around on various links and I found that it is available under the GPL license but it there is no specification of which version: GPL v2 or GPL v3.
Do you know which GPL version the DPL extension is licensed under? I can use products licensed under GPL v2 but not GPL v3. If it is GPL v3, is it possible to get a version licensed under GPL v2?

Thank you for your assistance.

Millie H.

:It is GPL v2. --[[User:Algorithmix|Algorithmix]] 15:33, 21 January 2010 (UTC)

Extension:DynamicPageList (third-party)

2009-06-15T21:10:53Z

Algorithmix:

''This is a third-party hosted extension, not to be confused with the [[Extension:DynamicPageList]] used on Wikimedia sites.''

* Note that the version running on Wikimedia sites was at some point in time renamed to [[Extension:Intersection]] to avoid confusion with the extension described here. But the documentation still was talking of "DynamicPageList" and the SVN path was not renamed.

* Recently 'Intersection' claimed back its ancient name and that is why you now find the documentation of 'Intersection' under 'Extension:DynamicPageList'.

* On the other hand the DPL extension described here was still named 'DynamicPageList' and new functions were added. At some point in time downward compatibility with the version running on Wikimedia sites was lost. The extension was renamed to 'DynamicPageList2' but the documentation was still talking of "DynamicPageList".

* Then another bunch of functionality was added and downward compatibility (with DPL2) was lost. The name of this version was changed back to DPL (which was thought to be 'free').

''All this has created much confusion. Read below for a suggestion on how to re-unite the different variants.''

This extension '''Dynamic Page List (DPL)''' has the same roots as [[Extension:Intersection]]. Until recently DPL was almost - but not exactly - downwards compatible with ''Intersection''. A lot of confusion comes from the fact that ''Intersection'' uses the tag <DynamicPageList> whereas '''Dynamic Page List (DPL)''' uses the tag <DPL>.

DPL offers functionality '''that goes far beyond''' ''Intersection''. Some of this functionality might be useful also on Wikimedia sites. But the problem is that inexperienced users or people with 'not-so-good-intentions' might write DPL statements which create significant database load.

A good solution - which also puts an end to all naming ambiguities of ''DynamicPageList, DPL, DPL2'' and ''Intersection'' looks like this:
# There should be only ONE extension.
# It should be called ''DynamicPageList'' (short name DPL).
# It should listen to the tags ''DynamicPageList'' and ''DPL'' for comaptibility reasons.
# Its sources should be in the mediawiki SVN
# It should be strictly downward compatible with ''Intersection''.
# It should offer a configuration switch (let us call it LevelOfFunctionality = LoF) which lets the administrator of a wiki decide, how much functionality will be offered to the users:
#* LoF = 0 is exactly identical with ''Intersection'' as of today.
#* LoF = 1 offers additional features which do not affect performance (mainly related to output formatting)
#* LoF = 2 offers additional features which are on the same conceptual level as ''Intersection'' like selection of pages by use of templates or by pagelinks. As the underlying table structures in the mediawiki database design are very similar to categories the performance cost of theses features are comparable in magnitude with ''Intersection'''s current features
#* LoF = 3 offers additional features which are more cost-intensive, like e.g. content transclusion from pages that occur in the DPL result; we think that a dedicated DPL cache could allow to offer these features also on high traffic sites - but this still has to be proved
#* LoF = 4 offers a last group of features which are a somewhat exotic and could create trouble if used by ignorant people (batch updates and batch deletions based on DPL query results)

DPL 1.8.0 made a huge step into that direction.

<big>'''After some bugfixes we now have DPL 1.8.4 as a stable release which can serve as a base for re-unification of all DPL variants.'''.</big>

Please help testing!

--------

'''Dynamic Page List''' (DPL) is a universal reporting tool for MediaWikis, listing category members and intersections with various formats and details. For usage documentation, see the <big>[http://semeb.com/dpldemo/DPL:Manual Manual]</big>. Typically the selection of pages to be shown will be based on one or more categories. But there are many other choices for selection criteria, like e.g. author, namespace, date, name pattern, usage of templates or references to other articles.

==Overview==
Assume you have written some articles about ''countries''. Typically these articles will have three things in common:
* They will belong to a common category
* They will have a similar chapter structure, i.e. they will contain paragraphs named 'Religion' or 'History'
* They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

===DPL generates reports on articles===
Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on the countries.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

With DPL you can ..

* generate a list of all those articles (or a random sample)
* show metadata of the articles (popularity, date of last update, ..)
* show one or more chapters of the articles ('transclude' content)
* show parameter values which are passed to the common template
* order articles appropriately
* present the result in a sortable table (e.g.)
* use multi column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* select by a logical combination (AND,OR,NOT) of categories
* specify a range for the number of categories the article must be assigned to
* select by a logical combination (AND,OR,NOT) of namespaces
* define a pattern which must match the article´s name
* name a page to which the article must or must not refer
* name a template which the article must or must not use
* name a text pattern which must occur within external links from a page
* exclude or include redirections
* restrict your search to stable pages or quality pages ("flagged revisions")
* use other criteria for selection like author, date of last change etc.
* define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* name
* date of last change
* popularity
* user who changed them last
* size
* restrict the output to the first n articles or to a random sample
* use descending or ascending sequence

'''Define attributes you want to see'''
* article name
* article namespace
* article size
* date of last change
* date of last access
* user who changed them last

'''Define contents you want to show'''
* whole article
* contents of certain chapters (identified by headings)
* text portions (defined by special marker tags in the article)
* values of template calls
* substitute the original template by a different one and show the output of that template

'''Define the output format'''
* specify headline and footer for your report
* use ordered list, unordered list
* use tables, sorted tables (using javascript)
* format table fiels individually by applying temnplates to their content
* use category style listing
* create "tag clouds" by varying output text size depending on popularity of pages
* multi column output
* truncate title or contents to a certain maximum length
* add a link to the article or to one or more of its chapters

===DPL generates reports on categories===
Apart from producing a list of pages which match certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

===DPL can be used for bulk editing===
Sometimes you want to perform a similar editing task on many articles (like adding a template at the beginning of the text). DPL has a feature which allows you to update other articles based on regular expressions. This feature is exeprimental and can be disabled in the DPL config file.

===DPL extracts objects and relations for generation of graphs with [[Extension:Wgraph]]===
With DPL you can generate output which is then fed into other MediaWiki extensions. An especially useful application of this kind is graph generation. DPL can analyse your wiki and prepare output which is then used by [[Extension:Wgraph]] to visualize it.

===DPL interacts with other extensions===
There is a special mechanism which allows to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can generate nice bar graphs or pie charts using DPL together with ''Ploticus'', you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a light-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

===DPL and performance===
With a few lines of DPL code it is possible to create huge output and CPU load (think of a DPL query which tries to include the contents of all articles in your mediawiki ;-)). Normally this is not a problem because users who write DPL queries have some level of expertise. If you are afraid, however, you can restrict the execution of DPL queries to ''protected articles''.
Apart from that the general performance of DPL on medium size wikis is quite acceptable (see the performance tests on the dpldemo website).

==See also==
===Further Reading===
DPL can do much more than we can explain here. A complete '''[http://semeb.com/dpldemo/DPL:Manual manual]''' and many examples can be found on the on the separate [http://semeb.com/dpldemo DPL website].

===''Call'' extension===
The website where DPL is offered for download also contains the ''Call'' extension which allows to call an arbitrary MediaWiki article from the command line or from a wiki link and pass parameters to that article at the same time.

===Other Application===
*[[DPL Page Name S/N Maker]]-Use this extension to create pages with serial number page names

===Related extensions===
* [[Extension:BackLinksFunctions|BackLinksFunctions]] counts backlinks
* [[Extension:News|News]] creates reports on page changes
* [[Semantic MediaWiki]] creates lists of semantic links
* [[Extension:TemplateTable|TemplateTable]] creates tables from template fields
* [[Extension:Ploticus|Ploticus]] can be used to create charts from DPL query results

* [[Extension:Todo Tasks]] creates/maintains todo tasks and notifies users to whom the task is assigned
* [[Extension:DPL Calendar]] a highly configurable calendar
* [[Extension:CategoryLink]] Creates a table of the wiki's categories

'''DynamicPageList''' is a Mediawiki 1.5 extension developed for [[n:en:Main Page|Wikinews]]. It is currently installed on all language Wikinews projects (see [[n:Wikinews:DynamicPageList]]) and Meta, and can be installed on any wiki. It allows wiki users to create a list of pages that are listed in a set of categories. See [[m:Help:DPL]] for general information.

==Installation==
The dynamic page list is in Wikimedia SVN. To install it, get [[Special:ExtensionDistributor/intersection|the extension files]] for your version of MediaWiki, and place them in the <code>extensions/intersection</code> directory. Then add <code>include("$IP/extensions/intersection/DynamicPageList.php");</code> to your LocalSettings.php file.

==Use==
DynamicPage list can be used with XML-like syntax in the wiki edit view. The parameters control the pages to list, order, and display mode. See the following sections for information on each parameter. For example, the following are the oldest five pages on this wiki that were recently moved to MediaWiki.org.

'''The information below may be outdated, see [[n:Wikinews:DynamicPageList]] for an up-to-date usage documentation.'''

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Pages recently transferred from Meta
count = 5
order = ascending
addfirstcategorydate = true
</DynamicPageList>
</pre>
</div>

===Page selection===
====category====
''category'' lists categories to intersect. DynamicPageList will list pages that are found in ''every'' category listed. A minimum and maximum number of entries to list is set in the extension's source code. You may use [[Help:Magic word|magic words]] like <nowiki>{{CURRENTMONTHNAME}}</nowiki> in the category name.

The syntax is <code>category = ''category name''</code>

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
category = Demo 1
</DynamicPageList>
</pre>
</div>

====notcategory====
''notcategory'' restricts the list of pages to those ''not'' in a particular category. You can use [[Help:Magic word|magic words]] like <nowiki>{{CURRENTMONTHNAME}}</nowiki> in the category name.

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
notcategory = Demo 1
</DynamicPageList>
</pre>
</div>

====namespace====
''namespace'' restricts the list of pages specified above to those in a particular namespace, specified by name or number (see the [[Help:Namespace#List_of_namespaces|List of default namespaces]]). Any invalid name is equivalent to the main article namespace.

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
namespace = Help
</DynamicPageList>
</pre>
</div>

====redirects====
''redirects'' determines whether or not to include [[Help:Redirect|redirect pages]]. The value can be ''exclude'' (default, don't list redirects), ''include'' (list redirects), or ''only (don't list pages that aren't redirects).

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
redirects = only
</DynamicPageList>
</pre>
</div>

====count====
''count'' restricts the number of results that are shown. By default, the pages added to the category most recently are shown (see [[#order 2|order]]). Note that the extension will not list more results than the maximum defined in the extension source code.

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
count = 2
</DynamicPageList>
</pre>
</div>

===Details displayed===
====shownamespace====
''shownamespace'' displays the namespace in the page names. The value can be ''true'' (default, display in name: [[Help:Contents]]) or ''false'' (don't display in name: [[Help:Contents|Contents]]).

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
shownamespace = false
</DynamicPageList>
</pre>
</div>

====addfirstcategorydate====
''addfirstcategorydate'' shows the date each article was added to category. The value can be ''true'' (display date) or ''false'' (default, don't display date). If many categories are specified, it uses the first category. The linked page names are prepended with the date formatted according to your local MediaWiki date display preferences.

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
addfirstcategorydate = true
</DynamicPageList>
</pre>
</div>

====mode====
''mode'' determines the format of the list. The value can be ''unordered'' (bulleted list), ''ordered'' (numbered list), or ''none'' (plain text with line breaks).

<div style="{{style example}}">
<pre>
unordered:
<DynamicPageList>
category = Demo
mode = unordered
</DynamicPageList>

ordered:
<DynamicPageList>
category = Demo
mode = ordered
</DynamicPageList>

plain text:
<DynamicPageList>
category = Demo
mode = none
</DynamicPageList>
</pre>
</div>

====suppresserrors====
''suppresserrors'' hides errors. The value can be ''true'' (hide errors) or ''false'' (default, show errors).

<div style="{{style example}}">

<pre>
true:
<DynamicPageList>
category = Dem
suppresserrors = true
</DynamicPageList>

false:
<DynamicPageList>
category = Dem
suppresserrors = false
</DynamicPageList>
</pre>
</div>

===Order===
====ordermethod====
''ordermethod'' determines the order and date to display. The value can be ''categoryadd'' (default, sort by date pages were categorised) or ''lastedit'' (sort by date pages were last edited).

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
addfirstcategorydate = true
ordermethod = lastedit
</DynamicPageList>
</pre>
</div>

====order====
''order'' decides the sort direction. The value can be ''descending'' (default, most recent to oldest) or ''ascending'' (oldest to most recent).

<div style="{{style example}}">
<pre>
<DynamicPageList>
category = Demo
order = ascending
</DynamicPageList>
</pre>
</div>

For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can generate nice bar graphs or pie charts using DPL together with ''Ploticus'', you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a light-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

===DPL and performance===
With a few lines of DPL code it is possible to create huge output and CPU load (think of a DPL query which tries to include the contents of all articles in your mediawiki ;-)). Normally this is not a problem because users who write DPL queries have some level of expertise. If you are afraid, however, you can restrict the execution of DPL queries to ''protected articles''.
Apart from that the general performance of DPL on medium size wikis is quite acceptable (see the performance tests on the dpldemo website).

==See also==
===Further Reading===
DPL can do much more than we can explain here. A complete '''[http://semeb.com/dpldemo/DPL:Manual manual]''' and many examples can be found on the on the separate [http://semeb.com/dpldemo DPL website].

===''Call'' extension===
The website where DPL is offered for download also contains the ''Call'' extension which allows to call an arbitrary MediaWiki article from the command line or from a wiki link and pass parameters to that article at the same time.

===Other Application===
*[[DPL Page Name S/N Maker]]-Use this extension to create pages with serial number page names

===Related extensions===
* [[Extension:BackLinksFunctions|BackLinksFunctions]] counts backlinks
* [[Extension:News|News]] creates reports on page changes
* [[Semantic MediaWiki]] creates lists of semantic links
* [[Extension:TemplateTable|TemplateTable]] creates tables from template fields
* [[Extension:Ploticus|Ploticus]] can be used to create charts from DPL query results
* [[Extension:Wgraph|Wgraph]] creates graphs from DPL output
* [[Extension:Todo Tasks]] creates/maintains todo tasks and notifies users to whom the task is assigned
* [[Extension:DPL Calendar]] a highly configurable calendar
* [[Extension:CategoryLink]] Creates a table of the wiki's categories

'''ArrayExtension''' defines an additional set of [[m:Help:Parser function|parser function]]s that operate on arrays.

==Functions==
This module defines these functions:
{| style="background:#EEE; cellspacing:2px; margin:4px; vertical-align:top; border:1px solid #CCC;"
! style="background:#BBB;" | group
! style="background:#BBB;" | functions
|-
| style="background:#DFD; border:1px solid #AFA;" |construct an array, (with unique,sort, print options)
| style="background:#DFD; border:1px solid #AFA;" |<tt>[[#arraydefine]]</tt>
|-
| style="background:#DFD; border:1px solid #AFA;" |print array
| style="background:#DFD; border:1px solid #AFA;" |<tt>[[#arrayprint]]</tt>,<tt>[[#arraysize]]</tt>,<tt>[[#arraysearch]]</tt>, and <tt>[[#arrayindex]]</tt>
|-
| style="background:#DFD; border:1px solid #AFA;" |alter an array (no print)
| style="background:#DFD; border:1px solid #AFA;" | <tt>[[#arraysort]]</tt>, <tt>[[#arrayunique]]</tt>, and <tt>[[#arrayreset]]</tt>
|-
| style="background:#DFD; border:1px solid #AFA;" |create a new array (no print)
| style="background:#DFD; border:1px solid #AFA;" |<tt>[[#arraymerge]]</tt>, and <tt>[[#arrayslice]]</tt>
|-
| style="background:#DFD; border:1px solid #AFA;" |create a new array without duplicates (no print)
| style="background:#DFD; border:1px solid #AFA;" | <tt>[[#arrayintersect]]</tt>,<tt>[[#arraydefine]]</tt>,and <tt>[[#arraydiff]]</tt>
|}

===arraydefine===
This function constructs an array (identified by 'key') using a list of 'values' separated by the 'delimiter'.
The variable can be accessed by other functions later.

Syntax:
<pre>
{{#arraydefine:key|values|delimiter|options}}
</pre>

Note(s):
* 'values' is a list of strings separated by 'delimiter'
* the resulting array is an array of strings.
* the default delimiter is ',' if not specified, a delimiter can be (i) a string (the white-spaces surrounding delimiter will be trimmed) or (ii) a perl regular expression (for advanced user only), e.g. '/\s*,\s*/' (see [http://us3.php.net/manual/en/function.preg-split.php preg_split])
* users can define an empty array (see example)
* users can specify options including unique, sort, and print (see example). new

Example(s):
{| border=1
|-
| define a one-element array named 'a'
| <pre>{{#arraydefine:a|red}}</pre>
|-
| define a four-element array named 'b', use default delimiter (',')
| <pre>{{#arraydefine:b|orange,red ,yellow, yellow}}</pre>
|-
| define/set an empty array named 'c'
| <pre>{{#arraydefine:c}}</pre>
|-
| define a one-element array named 'd', use no delimiter
| <pre>{{#arraydefine:d|apple, pear}}</pre>
|-
| define a one-element array named 'e', using ';' as delimiter
| <pre>{{#arraydefine:e|apple, pear|;}}</pre>
|-
| (advanced user only) define a three-element array named 'f', using '/\s*[;,]\s*/' as delimiter
| <pre>{{#arraydefine:f|apple, pear; orange|/\s*[;,]\s*/}}</pre>
|-
| define a three-element array named 'b1', use delimiter (','), "unique ,sort=desc, print=list" options (the array elements are unique, sorted in descending order and being printed). for more option-values of "sort" see [[#arraysort]]
| <pre>{{#arraydefine:b|orange,red ,yellow, yellow|,|unique,sort=desc, print=list}}</pre>
|}

===arrayprint===
This function prints the values of an array in customizable format.
For each value in the array, print 'subject' where all occurrences of 'search' is replaced with the value, deliminated by 'delimiter'

Syntax:
<pre>
{{#arrayprint:key|delimiter|pattern|subject}}
</pre>

Note(s):
* 'subject' now accept wiki link, templates and parser functions. new

Example(s):
{| border=1
|-
| print - use default delimiter ','
|<pre>{{#arrayprint:b}}</pre>
|-
| print - use <nowiki>''</nowiki> as delimiter
|<pre>{{#arrayprint:b|}}</pre>
|-
| print - use '<nowiki> </nowiki>' as delimiter
|<pre>{{#arrayprint:b| }}</pre>
|-
| embed wiki link
|<pre>{{#arrayprint:b| |@@@@|[[@@@@]]}}</pre>
|-
| embed Semantic MediaWiki link
|<pre>{{#arrayprint:b| |@@@@|[[prop1::@@@@]]}}</pre>
|-
| embed parser function
|<pre>{{#arrayprint:b| |@@@@|length of @@@@:{{#len:@@@@}}}}</pre>
|-
| embed template (with parameters)
|<pre>{{#arrayprint:b| |@@@@|{{f.tag{{f.print.vbar}}prop2{{f.print.vbar}}@@@@}}}}</pre>
|}

===arraysize===
This function returns the size (number of elements) of an array.
See: http://www.php.net/manual/en/function.count.php

Syntax:
<pre>
{{#arraysize:key}}
</pre>

Example(s):
{| border=1
|-
| size:
|<pre>{{#arraysize:b}}</pre>
|}

===arraysearch===
This function returns the index of the first occurrence of the 'value' in the array (identified by 'key') starting from the position identified by 'index' parameter, and returns '-1' when failed.
when 'yes' and 'no' specified, print value of yes if found, and value of no otherwise.
See: http://www.php.net/manual/en/function.array-search.php

Syntax:
<pre>
{{#arraysearch:key|value|index|yes|no}}
</pre>

Example(s):
{| border=1
|-
| return index of first occurrence of a value
|<pre>{{#arraysearch:b|white}}
{{#arraysearch:b|red}}</pre>
|-
| return index of first occurrence of a value
|<pre>{{#arraysearch:b|white}}
{{#arraysearch:b|red}}
use offset
{{#arraysearch:b|red|0}}
{{#arraysearch:b|red|2}}
use preg regular expression match
{{#arraysearch:b|/low/}}
{{#arraysearch:b|/LOW/i}} - case insensitive
{{#arraysearch:b|low}}
use yes no print option
{{#arraysearch:b|white|0|yes|no}}
{{#arraysearch:b|yellow|0|yes|no}}</pre>
|}

===arrayindex===
This function print the value of an array (identified by 'key') at position 'index'.

Syntax:
<pre>
{{#arrayindex:key|index|options}}
</pre>

Note(s):
* invalid index (non-number, out of bound) will result in printing an empty string.
* the index is 0-based, i.e. the first element's index is 0.
* users can specify options on default value

Example(s):
{| border=1
|-
| array index test
|<pre>{{#arrayindex:b|2}}</pre>
|-
| print default value for invalid index
|<pre>{{#arrayindex:b|-2|default=bad value}}</pre>
|}

===arraysort===
This function sorts an array in the following order.
* none (default) - no sort
* desc - in descending order (see: http://www.php.net/manual/en/function.sort.php)
* asce - in ascending order (see: http://www.php.net/manual/en/function.rsort.php)
* random - in random order (see: http://www.php.net/manual/en/function.array-rand.php)
* reverse - in reverse order (see: http://www.php.net/manual/en/function.array-reverse.php)
Syntax:
<pre>
{{#arraysort:key|order}}
</pre>

Note(s):
* each array element is a string

Example(s):
{| border=1
|-
| sort an array
|<pre>{{#arraysort:x|desc}}</pre>
|-
| randomize an array
|<pre>{{#arraysort:x|random}}</pre>
|-
| reverse an array
|<pre>{{#arraysort:x|reverse}}</pre>
|}

===arrayunique===
This function converts an array (identified by 'key') into a set (no duplicated members, no empty element).
see: http://www.php.net/manual/en/function.array-unique.php

Syntax:
<pre>
{{#arrayunique:key}}
</pre>

Example(s):
{| border=1
|-
| convert array to set
|<pre>{{#arrayunique:b}}</pre>
|}

===arrayreset===
This function free-up some or all defined arrays.

Syntax:
<pre>
{{#arrayreset:}}
{{#arrayreset:key1,key2,...keyn}}
</pre>

===arraymerge===
This function merges values of two arrayes (identified by 'key1' and 'key2') into a new array (identified by 'new_key').
See: http://www.php.net/manual/en/function.array-merge.php
Note: a wrong parameter will terminate this operation, and the array identified by 'new_key' will not be affected.

Syntax:
<pre>
{{#arraymerge:new_key|key1|key2}}
</pre>

Note(s):
* this merge is different from array_merge offered by PHP because it merges values instead of keys

Example(s):
{| border=1
|-
| merge two arrays
|<pre>{{#arraymerge:x|a|b}}</pre>
|-
| duplicate an array (keep the third argument of arraymerge empty
|<pre>{{#arraymerge:x|b}}</pre>
|}

===arrayslice===
This function extract a sub-array from an array (identified by 'key') into a new array (identified by 'new_key').
See: http://www.php.net/manual/en/function.array-slice.php

Syntax:
<pre>
{{#arrayslice:new_key|key|offset|length}}
</pre>

Note(s):
* offset indicates starting point of slice, it can be (i) non-negative number (ii) negative number for backwards index (e.g. the last element of the array's offset is -1). offset is different from index (which must be non-negative number)
* length indicates how many element to extract. If it is omitted, then the sequence will have everything from offset up until the end of the array.
* if offset is no less than array size, empty array will be returned, if offset if no greater than negative array size, a new array with all elements will be returned

Example(s):
{| border=1
|-
| extract a two-element slice starting from the element at offset 1
|<pre>{{#arrayslice:x|b|1|2}}</pre>
|-
| extract a two-element slice starting from the element at offset -2
|<pre>{{#arraymerge:x|b|-2|2}}</pre>
|}

===arrayintersect===
This function computes the set theoretic intersection of two given arrays (identified by 'key1' and 'key2'), and the result array is identified by 'new_key'.
See: http://www.php.net/manual/en/function.array-intersect.php

Syntax:
<pre>
{{#arrayintersect:new_key|key1|key2}}
</pre>

Note(s):
* this is a set operator, i.e., the returned array is a set without duplicated values.

Example(s):
{| border=1
|-
| intersect
|<pre>{{#arrayintersect:x|a|b}}</pre>
|}

===arrayunion===
This function computes the set theoretic union of two given arrays (identified by 'key1' and 'key2'), and the result array is identified by 'new_key'.
See: http://www.php.net/manual/en/function.array-union.php

Syntax:
<pre>
{{#arrayunion:new_key|key1|key2}}
</pre>

Note(s):
* this is a set operator, i.e., the returned array is a set without duplicated values.
* similar to arraymerge, this union operation works on values.

Example(s):
{| border=1
|-
| union
|<pre>{{#arrayunion:x|a|b}}</pre>
|}

===arraydiff===
This function computes the (set theoretic) difference of two given arrays (identified by 'key1' and 'key2'), and the result array is identified by 'new_key'.
The returned array (identified by 'key') is a set that contains elements in an array (identified by 'key1') but not in the other array (identified by 'key2').
See: http://www.php.net/manual/en/function.array-diff.php

Syntax:
<pre>
{{#arraydiff:new_key|key1|key2}}
</pre>

Note(s):
* this is a set operator, i.e., the returned array is a set without duplicated values.
* this function can be used to test sub-class relation

Example(s):
{| border=1
|-
| diff (b-a)
|<pre>{{#arraydiff:x|b|a}}</pre>
|-
| diff (a-b)
|<pre>{{#arraydiff:x|a|b}}</pre>
|}

==Installation==
This extension has been tested on MediaWiki 1.13+ and PHP 5. But most of its functions are compatible with PHP 4, so it is reasonable to try this extension on earlier versions of MediaWiki.
Please use the following instructions to install this extension.

1. Install source code
* you can copy the source code from [http://code.google.com/p/smwbp/source/browse/#svn/trunk/mediawiki/extensions/ArrayExtension SVN], and put them under "WIKI-PATH/extentions/ArrayExtension"
* or if you have ''shell access'', you can install using svn
svn co http://smwbp.googlecode.com/svn/trunk/mediawiki/extensions/ArrayExtension/

2. Append the following to <tt>[[LocalSettings.php]]</tt> (near the bottom) of your MediaWiki installation:
<source lang="php">require_once ("$IP/extensions/ArrayExtension/ArrayExtension.php");</source>

==FAQ==
===work with [[Extension:SemanticMediaWiki]]===
ArrayExtension allows users to populate an array using a SMW query result.

Example A. to create a list of instances of the class 'Color'
<pre>
{{#arraydefine:colors|{{#ask:[[Category:Color]][[:+]] |sep =, |limit=1000}} }}
</pre>

Example B. to create a unique list of values of property 'has color'
<pre>
{{#arraydefine:colors|{{#ask:[[has color::+]][[:+]] |?color= |mainlabel=- |sep =, |limit=1000}} |,|unique}}
</pre>

Example C. to deal with 2D array generated by SWM query (e.g. n-ary property)
<pre>
given a 2D array "red;#da2021, yellow;#fcff00, green;#00ff00"

1. create an array 'colors'
{{#arraydefine:colors|red;#da2021, yellow;#fcff00, green;#00ff00}}

2. split the first element of 'colors' into another array 'colors0'
{{#arraydefine:color0|{{#arrayindex:colors|0}}|;}}
</pre>

Note(s)
* [http://semantic-mediawiki.org/wiki/Help:Inline_queries#Standard_parameters_for_inline_queries semantic query parameters]
** 'limit=1000' option is used to exhaust all returned results of the semantic query
** 'sep=,' option is used to set the separator for entries of the results
** 'mainlabel=-' option cut of the page column

===work with [[Extension:DynamicPageList]]===

In a similar way as described above for SMW the '''ArrayExtension''' can be used to store results of a '''DPL query'''.

In the [http://semeb.com/dpldemo/index.php?title=DPL_Example_017 Example] we show how a result list can be "inverted". We collect all parameter values which are used by certain pages when they include a given template. We store pairs of ''template parameter value'' and ''pagename''. Then we sort the array and print the pairs. If consecutive array elements have the same first part (i.e. the parameter values are identical), the first part is only printed once. Thus we can construct a simple "inverted index". The same mechanism could be applied to other problems as well.

===iteratively access array elements===
We can iteratively access elements of an array using [[#arrayprint]] with the following code:
<pre>

{{#arraydefine:colors|Red,Blue,Yellow}}

{{#arrayprint:colors||@@@@|<nowiki/>
* length of @@@@: {{#len:@@@@}}
}}
</pre>

below is the expected output:
{|style="background:#DDD"
|
* length of Red: 3
* length of Blue: 4
* length of Yellow: 6
|}

for live examples, follow [http://tw.rpi.edu/portal/Help:ArrayExtension#iteratively_access_array_members this URL]

===work with [[Extension:SemanticQueryFormTool]]===
ArrayExtension allows users to populate an array using a SemanticQueryFormTool query result.

to create a list of instances of the class 'Color'
<pre>
{{#arraydefine: colors|{{#sask: ?Color | format=list | lastsep=}} }}
</pre>

'''Dynamic Page List''' (DPL) is a universal reporting tool for MediaWikis, listing category members and intersections with various formats and details. For usage documentation, see the [http://semeb.com/dpldemo/DPL:Manual manual]. Typically the selection of pages to be shown will be based on one or more categories. But there are many other choices for selection criteria, like e.g. author, namespace, date, name pattern, usage of templates or references to other articles.

==Overview==
Assume you have written some articles about ''countries''. Typically these articles will have three things in common:
* They will belong to a common category
* They will have a similar chapter structure, i.e. they will contain paragraphs named 'Religion' or 'History'
* They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

===DPL generates reports on articles===
Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on the countries.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

With DPL you can ..

* generate a list of all those articles (or a random sample)
* show metadata of the articles (popularity, date of last update, ..)
* show one or more chapters of the articles ('transclude' content)
* show parameter values which are passed to the common template
* order articles appropriately
* present the result in a sortable table (e.g.)
* use multi column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* select by a logical combination (AND,OR,NOT) of categories
* specify a range for the number of categories the article must be assigned to
* select by a logical combination (AND,OR,NOT) of namespaces
* define a pattern which must match the article´s name
* name a page to which the article must or must not refer
* name a template which the article must or must not use
* exclude or include redirections
* use other criteria for selection like author, date of last change etc.
* define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* name
* date of last change
* popularity
* user who changed them last
* size
* restrict the output to the first n articles or to a random sample
* use descending or ascending sequence

'''Define attributes you want to see'''
* article name
* article namespace
* article size
* date of last change
* date of last access
* user who changed them last

'''Define contents you want to show'''
* whole article
* contents of certain chapters (identified by headings)
* text portions (defined by special marker tags in the article)
* values of template calls
* substitute the original template by a different one and show the output of that template

'''Define the output format'''
* specify headline and footer for your report
* use ordered list, unordered list
* use tables, sorted tables (using javascript)
* format table fiels individually by applying temnplates to their content
* use category style listing
* create "tag clouds" by varying output text size depending on popularity of pages
* multi column output
* truncate title or contents to a certain maximum length
* add a link to the article or to one or more of its chapters

===DPL generates reports on categories===
Apart from producing a list of pages which match certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

===DPL can be used for bulk editing===
Sometimes you want to perform a similar editing task on many articles (like adding a template at the beginning of the text). DPL has a feature which allows you to update other articles based on regular expressions. This feature is exeprimental and can be disabled in the DPL config file.

===DPL extracts objects and relations for generation of graphs with [[Extension:Wgraph]]===
With DPL you can generate output which is then fed into other MediaWiki extensions. An especially useful application of this kind is graph generation. DPL can analyse your wiki and prepare output which is then used by [[Extension:Wgraph]] to visualize it.

===DPL interacts with other extensions===
There is a special mechanism which allows to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can generate nice bar graphs or pie charts using DPL together with ''Ploticus'', you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a light-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

===DPL and performance===
With a few lines of DPL code it is possible to create huge output and CPU load (think of a DPL query which tries to include the contents of all articles in your mediawiki ;-)). Normally this is not a problem because users who write DPL queries have some level of expertise. If you are afraid, however, you can restrict the execution of DPL queries to ''protected articles''.
Apart from that the general performance of DPL on medium size wikis is quite acceptable (see the performance tests on the dpldemo website).

===Further Reading===
DPL can do much more than we can explain here. A complete '''[http://semeb.com/dpldemo/DPL:Manual manual]''' and many examples can be found on the on the separate [http://semeb.com/dpldemo DPL website].

===''Call'' extension===
The website where DPL is offered for download also contains the ''Call'' extension which allows to call an arbitrary MediaWiki article from the command line or from a wiki link and pass parameters to that article at the same time.

== How about 1.9's? ==

Can any one tell me how to upgrade DynamicPageList2 to fit MW 1.9. I just upgraded it from 1.5 to 1.9, and find the category things not work any more. I only find:

<pre>
'''0.8.0 and above''', you have to install the [[mw:Extension:Labeled_Section_Transclusion|Labeled Section Transclusion]] extension too (both lst.php and lsth.php files).

For '''v0.7.0 and above''', if you want to apply the [[DynamicPageList2#category|'category' parameter]] on the Uncategorized pages, you are required to execute this manual query on your MediaWiki database, '''replacing <code>prefix</code> with your prefix''' if any:

CREATE VIEW prefix_dpl_clview AS
SELECT IFNULL(cl_from, page_id) AS cl_from, IFNULL(cl_to, '') AS cl_to, cl_sortkey
FROM prefix_page LEFT OUTER JOIN prefix_categorylinks ON page_id=cl_from
</pre>

And I think I should execute the mysql query on my database. I used no prefix, so I remove all the "prefix" in the syntax, but I got the following error message:
<pre>
SQL query:

CREATE VIEW dpl_clview AS SELECT IFNULL( cl_from, page_id ) AS cl_from, IFNULL( cl_to, '' ) AS cl_to, cl_sortkey
FROM page
LEFT OUTER JOIN categorylinks ON page_id = cl_from

MySQL said:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VIEW dpl_clview AS
SELECT IFNULL(cl_from, page_id) AS cl_from, IFNULL(cl_to, '' at line 1
</pre>

Can someone tell me what to do?

::The reason is that MYSQL 4.x does not understand the "CREATE VIEW" statement. You must use 5.0.1 or later.

==== Title or something like this ====
Hello! I would appreciate a bit of help, but I do not think this could be done. I would like to use this function with an "if" template but it does not work. I would like to add a title before the list but only if there are articles in the category. I though that with something like this would work:
<nowiki>{{#if:<DynamicPageList>
namespace=0
category=65655
count=8
</DynamicPageList>|
'''Title'''
<DynamicPageList>
suppresserrors=true
category=category name
count=10
</DynamicPageList>}}</nowiki>
However, it does not. I have tried with all kind of "if" functions. I have tried {<nowiki>{#if:}</nowiki>}, {{tl|qif}} with <nowiki>{{#ifeq:</nowiki>}}, with <nowiki>{{#switch:</nowiki>}} and with {{tl|switch}}. I have tried writing the "<tt>suppresserrors=false</tt>" and then saying that it should be equal to "DynamicPageList: No results!". Nothing has worked and therefore the problem is in this code, not in the if functions. Is there any way to fix that? If the answer is no, would it be possible to add a parameter such as "title" that would add a text before the list (in this case, the text would be "===Title===") if there are articles in the category?--[[User:SMP|SMP]] ([[:ca:Usuari Discussió:SMP|talk page]]) 08:53, 26 June 2006 (UTC)
:I tried a very simple example (using '''v0.6.3''') with the output I got on the right:
{|
! '''Input''' !! '''Output'''
|-
|<pre>
'''Without if function:'''

Teststart...<DPL>
debug=0
count=0</DPL>...Testend.

'''With if function:'''

Teststart...{{#if:<DPL>
debug=0
count=0</DPL>
|NOTEMPTY?!}}...Testend.
</pre>
|
'''Without if function:'''

Teststart......Testend.

'''With if function:'''

Teststart...NOTEMPTY?!...Testend.
|}
So obviously something wrong happens in the if parser function, not in the DPL. I did some very basic debugging on <code>ParserFunctions.php</code> (code for parser functions): I printed the <code>test</code> variable when the <code>ifHook</code> function is called (just insert a <code>print($test)</code>) and got '''<code>�UNIQ7fa446a58acad8f-DPL-5139857e4e92869200000002-QINU</code>''', which is not good and obviously not an empty string. My guess is something wrong is happening in the mediawiki code with hook, parsing and stuff, "and stuff" meaning that I did not do enough digging to be more exact and to solve the problem. So my question is: have you been able to use the parser functions (if or ifeq at least) with another parser extension (using tags like DPL) than the DynamicPageList2? This would help. --[[User:Dangerman|Dangerville]] 18:11, 3 September 2006 (UTC)

==== File Caching breaks the dynamic side ====
#DPG2 doesn't work with caching!

"$wgUseFileCache = true;" - So I need to click edit and change the content a very little bit to update the DPG listing!

Could you find a way to create a stop cache value in DPG2 or look into making some kind of __NOCACHE__ magic word?

==== Category Cloud ====

Is it possible to implement some sort of font changing system where the output with the most results could be given a bigger font like the [http://thepiratebay.org/searchcloud PirateBay Search Cloud]

Thanks

[[User:Mark Waters|Mark Waters]] 12:51, 8 January 2007 (UTC)

This is available since version 0.9 -- [[User:Algorithmix|Algorithmix]] 11:25, 17 February 2007 (UTC)

:Yes, but how is it executed? And can it also work with actual content words, instead of categories only? Thanks!

====Count n,n====
Syntax: count=n, with n a positive integer

I'm waiting for the article fetching mod to be completed and because I want to use it with news feeds (small pages based on templates) to list the last 25 news articles.
:''Article fetching mod available since 0.8.0.''

I want to be able to use the same thing for archieving next 25 older stories - eg Syntax: count=n,n (count=26,50)

My mediawiki has file caching and shouldn't cause too much lag when cached :) - [[User:58.84.66.222|58.84.66.222]] 18:49, 5 December 2006 (UTC)

====hiding article titles====
I'm using the "Transcluding visual headings" or article fetching and works fine apart from the fact it shows the title as per normal and then displays the actual article under it.

- article title 
THE ACTUAL ARTICLE 
- article title 
THE ACTUAL ARTICLE

Is there a way to remove the normal "DPL2" title listing and simply display the article instead?

:The experimental version on my personal discussion page should be able to do this. See "mode=userformat" in the request list below. If you do not specify %PAGE% you will not get any page title. --[[User:Algorithmix|Algorithmix]] 20:52, 11 January 2007 (UTC)

:::This is resolved with version 0.9, see mode=userformat -- [[User:Algorithmix|Algorithmix]] 11:27, 17 February 2007 (UTC)

==== Results / No Results Heading ====
It would be nice if you could specify a heading to be used for DPL if there are results, and similarly a heading if there are no results. e.g.
<code>
resultsheader= === Results Found! ===
noresultsheader= === No Results Found! ===
</code>

:Version 0.9 has that feature. It works exactly as you suggested. --[[User:Algorithmix|Algorithmix]] 21:33, 11 January 2007 (UTC)

==== date formatting ====
<code>addeditdate</code> et al. would be more versatile if they accepted not just "true", but actual date formating as options. e.g.

addeditdate="("F d")"

Would give "(October 23)", per the relatively standard date formatting functions, [http://meta.wikimedia.org/wiki/ParserFunctions#.23time ParserFunctions] and [http://www.php.net/date php's date].

: ''The idea in addeditdate=false/true was to rely on the user's preferences or your wiki global settings for the date-time format, to use features of MediaWiki. But yes, more versatility is always welcome. I will look into the ParserFunctions implementation when I get to provide this feature.'' --[[User:Dangerman|Dangerville]] 19:10, 23 October 2006 (UTC)

==== DPL and templates ====

I want to put DPL into a template, likeso:
<pre>
<includeonly>
<DPL>
category=news
category={{{1}}}
count={{{2|5}}}
</DPL>
</includeonly>
</pre>

or alternatively, use dynamic [[:m:ParserFunctions]], likeso:
<pre>
<DPL>
category={{ #time: F d, Y }}
count=15
</DPL>
</pre>

In both cases, it would seem as though DPL is not interpreting the variables or expressions. This seems like a rather intuitive use for it; any help would be appreciated. [[User:Bmh ca|Bmh ca]] 16:25, 23 October 2006 (UTC)

: ''Indeed, DPL category param accepts magic words but not templates or template-like constructs like parser functions at the moment (I actually haven't tested these so this may not be exactly true).

::''would seemingly substitute variables appropriately. Hopefully this would be the only line that needs to be changed, but I'm cautious that would be wishful thinking.'' [[User:Bmh ca|Bmh ca]] 20:42, 23 October 2006 (UTC)

====Page transclusion: format page link/title as "headline" link or customizable link like "read more"====
One additional thing which might be important is to add an additional "mode" parameter to format the pagename/title/link to the complete page, as either a "headline" link, or as a link ("read more.../customizable text") appended at the end of the included text, or maybe both. Yes I know I am asking for a lot, but better take all things into account.

==== Add Format Option for display in sidebar ====
Can someone add a format option so the pages can be displayed in a sidebar? I know it can't be too difficult... in the sidebar, I'm thinking you could just put:
<pre>
* recently updated
<DPL>
category=somecategory
ordermethod=lastedit
sidebar=true
</DPL>
</pre>

What would be displayed is something like
<pre>
* recently updated
** wikilink1|title1
** wikilink2|title2
</pre>

Also there should probably be a "limit number of characters in title to display" option also. Additionally, if there was an option to define the wrapper tags, might be a little more open ended... might get a little complicated then... thanks for the help, guys!

:OK. I think we are looking at a new 'mode=sidebar' here. For "limit number of characters in title to display", it's available. See [[DynamicPageList2#titlemaxlength|titlemaxlength]]. Even though I have a rough idea, could you explicit your "option to define the wrapper tags"? Thanks. --[[User:Dangerman|Dangerville]] 16:47, 1 October 2006 (UTC)

===== Creating a CSS Menu using DPL2 =====
: I've taken the two previous comments that were here and merged them into one comment for consistency. You can view them using the history function if you really want..

: The context of this usage is a corporate intranet where categories act as topic indexes, for example indexes for documentation for clients, so you'd have a category named clientA, another named clientB and so on. Here we use DPL2 to autogenerate an unordered list that we can then use with some simple CSS to make a :hover menu. When an article is added to a category, the menu is dynamically updated - as if by magic.

: Browsers that do not support the required CSS or have javascript disabled will just generate a list of the top level links, in the aforementioned context you'd just have a list of categories - no submenus.

: ''Update 27/08/06 - Cleaner, more accessible version:''
:: ''Update 26/09/06 - Corrected Javascript slightly (now IE wont cry if it doesnt find id="menu", if you're silly enough to leave script debugging on)''
::: ''Update 01/10/06 - Simplified DPL input''

: Simply append the following into skins\common\IEfixes.js
<pre>
// Enable DPL2 Menu

sfHover = function() {
var dmenu = document.getElementById("dmenu");
if(!dmenu) return; /* no menu on page */
var sfEls = dmenu.getElementsByTagName("li");
for (var i=0; i<sfEls.length; i++) {
sfEls[i].onmouseover=function() {
this.className+=" sfhover";
}
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
}
}
}
if (window.attachEvent) window.attachEvent("onload", sfHover);
</pre>

: Then in MediaWiki:Common.css pop in the following CSS. ''Update 27/08/06 - Cleaner, more accessible version:''

<pre>
#dmenu, #dmenu ul { /* all lists */
font-size: 95%;
padding: 0;
margin: 0;
list-style-type: square;
float : left;
width : 11em;
}

#dmenu li { /* all list items */
font-size: 95%;
position : relative;
line-height : 1.25em;
margin-bottom : -1px;
width: 11em;
}

#dmenu li ul { /* second-level lists */
position : absolute;
left: -999em;
margin-left : 11.05em;
margin-top : -1.35em;
}

#dmenu li a {
width: 11em;
display : block;
padding : 0 0.5em;
z-index:10;
}

#dmenu li a:hover {
text-decoration: none;
background: #336699;
color: #FFFFFF;
}

#dmenu li:hover ul, #dmenu li.sfhover ul{
left: -999em;
}

#dmenu li:hover ul, #dmenu li.sfhover ul { /* lists nested under hovered list items */
left: auto;
}
</pre>

: Your DPL input would be something like this:
<pre>
<ul id="dmenu">
<li>[[:Category:Client1|Client 1]]<dpl>category=Client1</dpl></li>
<li>[[:Category:Client2|Client 2]]<dpl>category=Client2</dpl></li>
<li>...</li>
</ul>
</pre>

From '''v0.7.7''', you can do this '''in one shot''' (with the '+' to have category headings):
<pre>
<dpl>
category=+Client1|Client2|Client3...
ordermethod=category,<second param>*
headingmode=unordered
hlistattr= id="dmenu"
mode=unordered
</dpl>
</pre>
'' *'<second param>' can be lastedit, firstedit, sortkey, etc. See [[DynamicPageList2#ordermethod|ordermethod]]. ''

: Which would generate output like
<pre>
<ul id="dmenu">
<li>
<a href="/wiki/Category:Client1" title="Category:Client1">Client 1</a>
<ul>
<li><a href="/wiki/Client1_Page1" title="Page 1">Page 1</a></li>
<li><a href="/wiki/Client1_Page2" title="Page 2">Page 2</a></li>
</ul>
</li>
</pre>

==== Excludetitle? ====
Is there a way to exclude one specific page (by title) from the results? This would be useful where DPL is used to insert a list of pages for a category into an individual page in-category, but where there's no need for the page to link to itself. For instance, http://desencyclopedie.org/index.php?title=Liste_des_villages_du_Qu%C3%A9bec&oldid=50340 lists each individual village in the category, but the "list of villages..." page itself needs to be removed from the output.
:Do you just want to remove pageX from the results of a DPL if it is on that same pageX (the DPL would do this dynamically, without you specifying the title to remove)? or being able to remove specific pages from the results by specifying titles (pageX or another) with something like an "excludetitle" parameter? or both?! (These are different things with different implementations.) --[[User:Dangerman|Dangerville]] 18:27, 3 September 2006 (UTC)

==== mode=count ====

Should be easy enough to tweak :)

: Before v0.7.7, DPL2 was using date() as you suggest, until the feature request "Display time of pagetouched" (closed) required both date and time. So to attempt to make everybody happy, soon, when providing [[Talk:DynamicPageList2#date_formatting date formatting]] to DPL2 users, they'll be able to do whatever they want with the date. How does that sound? --[[User:Dangerman|Dangerville]] 17:28, 11 November 2006 (UTC)

==== Page transclusion: Possible enhancement ====
'''Possible enhancement (1):''' Currently labels must be part of the text source of an article itself. It would be nice if the label could be buried within a template. Partly for esthetical reasons and partly as this would allow to easily transclude the contents of template parameters. 
'''Example:''' You use a template in your articles for, say, year of birth and year of death of people; you use DPL2 to show a list of all people who contributed to ''xyz'' (maybe using the '''linksto=xyz''' phrase). If the transclusion does not understand templates, you will have to put section markers around the parameters when calling the template in each article. If transclusion can handle templates you will be able to hide the labels in the template.
::The idea behind all this is to have a ''semantically useful summary of related topics in one article'' so that the user gets a clearer understanding of the relevance of listed (or referencing) articles, especially in combination with the ''linksto'' option. [[User:Algorithmix|Algorithmix]] 14:52, 15 December 2006 (UTC)

==== titlematch = "pattern" : restricting the result to certain articles ====

It would be nice to have a name matching pattern for articles we want to see in the result set.

* titlematch = pattern

should do the job. "pattern" could be a SQL-LIKE expression. So titlematch=a% would match all articles the names of which begin with an "a". An implementation can be found on my [[user_talk:Algorithmix|homepage]].

[[User:Algorithmix|Algorithmix]] 20:28, 19 December 2006 (UTC)

==== pattern match for categories ====
(seems close to the previous topic)

Our wiki's subcategories' names usually starts with the upper categorie's name (for example : DB category includes DB-Oracle and DB-PostgreSQL). I tweaked the code to use ILIKE instead of = in the appropriate request :

DynamicPageList2.php l.786 :

$sSqlSelectFrom .= (...) AND (cl' . $iClTable . '.cl_to = ' . $dbr->addQuotes($aIncludeCategories[$i][0]);
is now
$sSqlSelectFrom .= (...) AND (cl' . $iClTable . '.cl_to ILIKE ' . $dbr->addQuotes($aIncludeCategories[$i][0]);

now I can use category=DB% to match the category and all subcats (works with PostgreSQL as Wiki DB - might also work with MySQL LIKE).

:You may want to have a look at http://semeb.com/dpldemo; you fill find a more recent version of DPL which contains a match operator for categories and many more features you couldn´t even think of ;-) [[User:84.188.160.128|84.188.160.128]] 20:01, 5 June 2007 (UTC)

==== mode=userformat : more flexibility with output formatting ====

I suggest to define a new mode called ''userformat''.

In this mode DPL2 will reset all internally pre-configured output tags an give the user full control over the output. We only need a new property (called ''listseparators'') to define the user specific tags to be used.
<pre><nowiki>
mode=userformat
listseparators=t1,t2,t3,t4
</nowiki></pre>
tag1 and tag4 wrap the whole output, tag2 and tag3 wrap each item.

For full flexibility we use a symbol (%PAGE%) to give the precise location where the name of the article (or a link to it) should fit in. All tags should be WIKI style. Because wiki formatting depends on linefeeds (tags like * or # for enumerations only work at the beginning of a line) we need a symbol ('\n') which acts as a linefeed.

Thus we can now write
<pre><nowiki>
mode=userformat
listseparators=,\n*[[%PAGE%]]
</nowiki></pre>
Yes, that´s all you need. The first parameter is empty, the second says that before outputting the page link we should have a linefeed followed by an asterisk. And that is wiki syntax for simple unnumbered lists.

Why all that, you might ask. Have a look at [http://bridgelexikon.de/Hilfe:DPL-Test_A]. You will find a demonstration of the flexibility of the proposed feature. The source code can be found on my [[user_talk:Algorithmix|homepage]].

The real power comes when you combine the new ''page inclusion feature'' with the ''flexible formatting'' proposed here.
On my demo page you will find a ''sortable wikitable'' which is composed of articles and some selected sections of each article. You can re-arrange the DPL2 output based on article names AND based on the contents of the chapters´ contents! Isn´t that nice?

To achieve this some changes in the code had to be done which mainly affect the point in time when you trigger the recursive parse of the output. See my comments in the source code.

Finally I´d like to give a more ambitious '''example''' (in German, please ignore the contents). Here [http://bridgelexikon.de/Alle_Bridgereisen] you will find a sortable list of offerings for bridge journeys. The first column links to the page of the agent providing the journey. On this page templates are used to facilitate editing and to create a standardized appearance. As the agent´s name is only relevant in the summary list it is suppressed in the listing within the agent´s home page.

[[User:Algorithmix|Algorithmix]] 20:28, 19 December 2006 (UTC)

==== using DPL as a parser function: #dpl: ====

Currently DPL2 is written as a normal user extension. This means that you have to wrap the dpl2 statements within dpl tags. Besides that mediawiki offers the so-called user functions which are better integrated into the parser. Their advantage is that you can use complete wiki syntax (including #if:) within the parameter calls. So you could use "category=<nowiki>{{{1}}}</nowiki> within a template and pass the desired category as a parameter. If you wanted to have more page lists with similar layout you could bury the details of layout settings within such a template.

As it was not too complicated to do I prepared a version of DPL2 which can be used BOTH ways, i.e. with tags and as <nowiki>{{#dpl:parameter=value|parameter=value|...}}</nowiki>. See my [[user_talk:Algorithmix|homepage]]. -- [[User:Algorithmix|Algorithmix]] 09:11, 8 January 2007 (UTC)

====Simpleton's page transclusion====
I cannot seem to find a way to include the first ''x'' number of characters from an article (eg the first sentences followed by "..."). My aim is to give a flavour of the article's content, without having to click through to it. I would like to not have to add additional markup to the articles in the list. Did this feature once exist or am I imagining this?

--[[User:Lanma726|Lanma726]] 03:26, 4 February 2008 (UTC)

This feature exists in [[Extension:DynamicPageList]] but not here in the old version. [[User:Algorithmix|Algorithmix]] 20:59, 6 April 2008 (UTC)

=== Closed ===
==== Display Text from Articles ====

Currently DPL2 displays article names and optionally some page attributes like authors or dates of change. It would be of great value to show also text portions from the articles. This has already been adressed in two requests above, named
* Include whole article
* Include first lines of content

My suggestion is to integrate a very nice extension called [[mw:Labeled Section Transclusion]] into DPL2. Steve Sanberg offers with ''LabeledSectionTransclusion'' a general mechanism of defining '''labeled sections''' within an article which can then be included from another article. Sections may overlap. One can even have several text pieces within an article with identical label and in the simplest case the whole article might be defined as exactly one labeled section. On the other hand there may be situations where you want to include exactly one '''chapter of an article''' (i.e. the text after a <nowiki>=== heading ===</nowiki> up to the next heading). In those cases you would not want to put section markers around each paragraph ...

So I did two things:
* First I made an enhancement to Steve´s extension which allows to transclude a chapter by putting a "#" before the heading name. This is similar to the way you make hypertext references to chapters of an article like <nowiki>[[my article#its first chapter]]</nowiki>.
A chapter extends from the line after the heading to the line before the next heading (regardless of its level!) or to the end of the text. This is a very pragmatic definition but simplicity also has its advantages ..
* Second I put effort in calling Steve´s extension as a subroutine from within DPL2. This is somewhat tricky because you want to expand wiki syntax in the transcluded text.

My combined version of both extensions works very well for my own purposes but I guess it should be thoroughly tested by Cyril (if he wants to adopt it) before being released into DPL2. Meanwhile the source code can be found on [[User talk:Algorithmix|my personal discussion page]]. Maybe both extensions could be merged?

The Suggested new syntax is as follows:

;addsection=label,..: used to specify one or more section labels or #chapters for the "transclusion"; if the name starts with a "#" it is assumed to be a heading, otherwise it is understood as a section label.
;sectiontext=groupStart,sectionStart,sectionEnd,groupEnd: used to insert layout tags into the output. The inner tags are put around each section, the outer tags are used in addition for the whole bunch of sections.

known bug:
Section markers will not be stripped off if they are part of chapter which is transcluded via the "addsection=#chapter" syntax. Maybe this can be fixed but it is a rather strange constellation anyway.

[[User:Algorithmix|Algorithmix]] 22:40, 23 November 2006 (UTC)

:Although I haven't tested it, I suspect the bug is because it uses a local parser instance, which doesn't have the LST hooks, and thus doesn't recognize the LST markup. Using the regular parser's recursiveTagParse() method (for a 1.8+ parser) should fix this. -[[User:Sanbeg|Sanbeg]] 19:47, 27 November 2006 (UTC)

''Great! Sorry for the big delay. I've just got back into it. I'll review this and at least integrate this into DPL within the next 2/3 days. The "#chapter" feature may wait a little longer because this requires your modified version of Sanbeg's extension a priori. It would be easier for users to use his extension as it is, all the more as there seem to have been some significant changes to it since then.'' --[[User:Dangerman|Dangerville]] 00:07, 11 December 2006 (UTC)

As far as I can see you refer to the "standard" version of ''LabeledSectionTransclusion'' which is very flexible but urges authors to add special section marker tags to the articles (unless they want to include the whole article). I still feel that inclusion of sections based on their heading (as it found its way into lsth.php quite recently) might be of some value. And beyond that (but that may be hard to do) inclusion of parameter values of templates which the included page uses.
::The idea behind all this is to have a ''semantically useful summary of related topics in one article'' so that the user gets a clearer understanding of the relevance of listed (or referencing) articles, especially in combination with the ''linksto'' option. [[User:Algorithmix|Algorithmix]] 14:52, 15 December 2006 (UTC)

:''I agree and was intending to take care of it after looking at lsth.php... and now it's done. DPL2 0.8.1 now provides inclusion of sections based on their heading with includepage=#heading, using the main LST function in lsth.php. Moreover, the "known bug" you mentioned has been fixed using Parser::recursiveTagParse() as Steve Sanbeg suggested. As for the inclusion by passing values to template parameters in the page (I'm not quite sure about how to make that simple for DPL2 users), it would be good to make a separate feature request... Thanks for your ideas! and thanks to Sanbeg for his extension.'' --[[User:Dangerman|Dangerville]] 02:29, 16 December 2006 (UTC)

==== Include first lines of content ====
It could be a nice feature, if the DPL could include a few lines of text of each page on the list. This would be very useful for semi-automatically created content lists on main pages and portal pages. Some of our content consists of long articles, blog entries and newsposts. In all cases, the titles doesn't precisely give away the content - so it would be nice with some extra information on a dynamic list.

It could be done in several ways :

* A la search results pages (created semi-automatically)
* Could be limited to a user-specified number of characters to be included, for each page on the list.
* Content could be rendered (preferably), or shown wiki-text (as search result pages).
* Alternatively, a manually entered and tagged subtitle (on the respective pages) could be included (something like <subtitle>This article deals with...</subtitle>).

Otherwise, great work! --[[User:Morten Blaabjerg|MortenB]] 17:08, 18 July 2006 (UTC)

:''The [[Newest_Pages_Blog_%28extension%29|Newest Pages Blog]] extension offers the kind of summary feature you are looking for, using a <code>newestpagesblog-summaryendmarker</code> (cf. readme). Have you found a similar feature in another extension or elsewhere (with the source)? If not, I (or others welcome) intend to integrate/adapt their solution (in)to DPL2. Sounds reasonable. --[[User:Dangerman|Dangerville]] 06:51, 24 July 2006 (UTC)''

::Thanks for the tip :-) - Sounds interesting; I will check it out right away. I have been through most of the extensions listed on this site and haven't found anything else yet which comes close. I'll get back to you here, if I find other extensions, which might be useful to look at.

::However, the DPL could perhaps *simply* make use of the template mechanisms and <nowiki><noinclude></noinclude></nowiki> tags already in place in MW? What I am thinking, is that if DPL allow an option to be set in the dynamic list to include the complete article in the list, the user could simply specify what parts of pages to include and what not to. This would make brilliantly possible the kind of dynamic lists I look for to make our front page almost completely automatically updated. This would also provide the ultimate freedom to include on lists what you wanted from specific pages. It should be a perfectly optional setting in a DPL, which by default should be off. Of course, possibly the best user-friendly solution would be one not requiring users to enter tags at all on their newsposts (requiring some kind of specified character count only in the DPL, which is used if no tags are set).

::I'm not sure if this goes too far beyond the intention of this extension, or it belongs in an extension of its own. Clearly too much "checking content" of listed pages, will slow the extension down somewhat. --[[User:Morten Blaabjerg|MortenB]] 12:26, 25 July 2006 (UTC)

::I've looked at the [[Newest_Pages_Blog_%28extension%29|Newest Pages Blog]] extension, and it sure does things along the lines I try to describe above, if only in a slightly less flexible way than the DPL... I'll try it out. However, it sure would be great to include this kind of functionality, if possible, into the DPL, as the functionality seems much more flexible with this approach. --[[User:Morten Blaabjerg|MortenB]] 16:18, 25 July 2006 (UTC)

:::''I read too fast the first time. It is much more an '''excerpt''' feature than summary, which means that your idea of using special tags for text to be included in the list is more appropriate (much more flexible) than the '''summary''' solution of the [[Newest_Pages_Blog_%28extension%29|Newest Pages Blog]] extension. So relying on a special tag like <nowiki><noinclude></nowiki> (or <nowiki><includeonly></nowiki>?) sounds good. In any case, as you suggested, this should be combined with a user-specified DPL2 parameter that sets the max number of characters to be included, in case:
:::#''the special tag (e.g. <nowiki><noinclude></nowiki>) is not used in the page at all;''
:::#''special tag is used but too too much text (really) included with that.''
:::''Last, if special tag is used more than once in same page, DPL2 would include text from the first chunk only. --[[User:Dangerman|Dangerville]] 07:12, 26 July 2006 (UTC)''

::::Sounds brilliant :-) - With this functionality it could be used for either - a list of pages with a short summary/subtitle, or inclusion on the list of an excerpt or the near complete page.

:''This is possible with includepage=subtitle (resp. includepage=summary, whatever you prefer) and using sections labeled 'subtitle' (resp. 'summary') in your articles, since v0.8.0.''

==== Include whole article ====

Instead of just enumerating the title with the link, just include the whole articles found. This could be used for a news area where the articles are short. Short but very helpful.

For example:
<nowiki>
<DPL>
namespace=News
includeWholeArticle=True
</DPL></nowiki>

would result in something like:
<nowiki>
{{:News:news topic 1}}
{{:News:news topic 2}}
{{:News:news topic 3}}
{{:News:news topic 4}}</nowiki>

I think what i did in the example above was page inclution, which i also think can only do one insert. Use whatever is necessary, mine's just an example anyway.

::''I haven't looked at how to implement this feature yet, but in the meantime, (for people willing to look at the code...) if you could point out the MediaWiki function that handles page transclusion (or the closest to it) or, if not, how MediaWiki does it, it would make the job much easier. --[[User:Dangerman|Dangerville]] 11:09, 25 August 2006 (UTC)''

::::Thanks... I got that and Jami's example is quite explicit. But extensions can return '''HTML code''' only, '''not wiki text'''.

==== ORIGINAL creation date only order method ====
I run this setup

<pre><nowiki><DPL>
count=25
shownamespace=false
category=Wiki News
order=descending
ordermethod=categoryadd
addfirstcategorydate=true
</DPL></nowiki></pre>

and the issue is.. this seems to include edits aswell!!

I want something very simple.. a list with the items from "Category:Wiki News" listed in order of ORIGINAL creation date.. 
I do NOT want the news page re-ordered if I make a typo and correct it. 
This seems pretty simple and Id expect it to be so..

Minor update doesn't work under this setting or Id be using that to fix my problem!

: ''Well, in your example, you are using "ordermethod=categoryadd". This will sort them by date the article has been added to the category "Wiki News" (by looking at the <code>cl_timestamp</code> field in the <code>categorylinks</code> table and nothing more). If you want the pages sorted by date of creation, use '''ordermethod=firstedit''' ([[DynamicPageList2#ordermethod|more info]]) because the original creation date is the date of first edit in mediawiki, or rigorously speaking, the rev_timestamp of the first revision entry in the <code>revisions</code> table (which is what ordermethod=firstedit is using). --[[User:Dangerman|Dangerville]] 19:46, 23 October 2006 (UTC)''

==== Do not set a category ====
It shoulb be fine to have an option to display all articles from all categories if we have set a namespace.
For example if we have set a namespace ant not a category, we display article from all categories from this namespace.

::...?? OK, it's been a while, I consider this is solved for you. --[[User:Dangerman|Dangerville]] 15:28, 1 October 2006 (UTC)

==== Display time of pagetouched ====
For purpose of a group (projectwise working) keeping pages up to date with a certain category, it would be nice if in the list not only the date of pagetouched could appear, but also the time. In that case everybody in our projectgroup can see the last changes in a certain category, even within the same date...

Unfortunately I've just tried to build the first line of PHP in my whole life and that bad line of code looks like this in the
function DPL2OutputListStyle: 
<pre>
Original line at row 819 in the source:

$r .= $wgLang->date($aAddDates[$i]) . ': ';

Very bad example of my wish:
$r .= $wgLang->date($aAddDates[$i]) . ' ' . substr( '0'.( substr($aAddDates[$i],8,2) + 2 ),-2) . ':'.substr($aAddDates[$i],10,2).' : ';
</pre> 

Sorry about the hard coded output, but that's my starting knowledge of about searching 2 hours in PHP documentation on different sites...
The addition in the hour output (substr(....,8,2)) is the time difference, which should come from the "preferences" in Mediawiki, but due to my low knowledge I've hard coded it in this example.

:I appreciate the effort. You can just use mediawiki date/time functions, it will spare you some sweating. The <code>date</code> function is coded in <code>languages/Languages.php</code> (see MediaWiki source). There, you will also find what you need, in particular the <code>timeanddate</code> function that shows time and date, using preferences or not (depending on args). The best way to start is to look there (the comments are very helpful). Now, we have to think of how to provide the feature to DPL users, if they want just dates, or times and dates (what do we do with the add*date params)... --[[User:Dangerman|Dangerville]] 18:54, 3 September 2006 (UTC)

::Since '''v0.7.7''', you can get the time (and date) according to your mediawiki config or the user's preferences if logged in. --[[User:Dangerman|Dangerville]] 15:28, 1 October 2006 (UTC)

==== linksto=article ====

I added some code to use DPL2 for the creation of a list of articles which '''link to a certain page''' AND which belong to a certain category. This would allow to produce ''inverted lists'' which are semantically meaningful. For instance, you could easily create a list of articles which are in category "poet" and which link to, say ''Dublin''.

Here is a source code diff to the latest version of DPL2:

<pre>
110a111,116
> * this parameter restricts the output to articles which contain a reference to the specified page.
> * the special value "HERE" stands for the current page
> * Examples: linksto=my article , linksto=Template:my template , linksto = HERE

> 'linksto' => array('default' => ''),
> /**

> $sLinksTo = $parser->getTitle()->mDbkeyform;
> break;

</pre>

A small change in the warning texts would also belong to this change:

<pre>
'dpl2_debug_' . DPL2_WARN_NOINCLUDEDCATSORNS => "WARNING: It is strongly recommended to either limit the number of results with the 'count' parameter or include at least one category / namespace or use the 'linksto' parameter. If not, the generation of the page list can be quite resource and time-consuming.",
</pre>

I would be glad to see this new feature find its way into the official version. How do you think about it, Dangerville?

-- [[User:Algorithmix|Algorithmix]] 11:25, 17 September 2006 (UTC)

: This is now available in '''v0.7.7'''. One change that is worth being noticed: instead of ''HERE'', use the magic word <nowiki>{{FULLPAGENAME}}</nowiki> to get pages linking to the current page. You can use all magic words that your MediaWiki supports. --[[User:Dangerman|Dangerville]] 15:28, 1 October 2006 (UTC)

==== Category value for Uncategorized pages ====
Also a special 'category=nocat' category would be nice, i.e. all new pages or edits for pages which have not been assigned to any category. That would be useful for site administrators and pedants everywhere :) --[[User:193.60.81.207|193.60.81.207]] 19:42, 11 November 2005 (UTC)

::That already exists, it's called [[Special:Uncategorizedpages]]. [[User:Pfctdayelise|pfctdayelise]] 16:38, 24 August 2006 (UTC)

:Unlike [[Special:Uncategorizedpages]], this feature aims to combine all the other DPL features with it, like restrict by namespace or all the fancy display options. '''This feature is now available in v0.7.0.''' (You have an extra step in the installation.) --[[User:Dangerman|Dangerville]] 16:56, 17 September 2006 (UTC)

==== Supress 'minor' edits... ====
There should be an option (prolly the default) to ignore page updates which are minor. I.e. they should not get pushed up onto the top of recently edited pages in the DPL. Setting something like 'minoredit=TRUE' would restore the current behaviour.

:This is now available in 0.6.4 with the 'minoredits' parameter. --[[User:Dangerman|Dangerville]] 18:58, 11 September 2006 (UTC)

:The problem is that using 'minoredits' parameter excludes such articles from the list completely, which should not be the case. To me the functionality is faulty, and this should be fixed.

==== Limit number of characters ====
Doubt this will make it, but on my wiki I have a few pages with long titles. On my Main_Page I have a list off to the side that displays the last edited in certain categories. Well, I would really like to have it show the first X number of characters then just add some ... after it or something.
:This is now available in '''v0.6.3'''. See [[DynamicPageList2#titlemaxlength|titlemaxlength]] parameter. --[[User:Dangerman|Dangerville]] 15:36, 3 September 2006 (UTC)

==== inline format, items italic or bold ====
I prefer ( cat1 • cat2 • ...) and if not already the case, the ability to have the items in bold or italic. (Kevin Baas) [[User:69.211.213.120|69.211.213.120]] 21:02, 10 October 2005 (UTC)
:''Your example ( cat1 • cat2 • ...) is confusing. Do you mean ( page1 • page2 • ...)? In this case, it is available since v0.3.3 with 'ordermethod=inline'.
:: For items italic or bold, it is now available in v0.6.2. Use <code>itemattr= style="font-style: italic;"</code> for italic, <code>itemattr= style="font-weight: bold;"</code> for bold, or add a custom class to one of the Mediawiki CSS files and use the class attribute accordingly. --[[User:Dangerman|Dangerville]] 18:25, 29 August 2006 (UTC)

==== Having a space in <tt>inlinesymbol</tt> argument ====
Since the inline mode of my own extension, [[Sort2]], was inspired by the same mode of DPL, I though I let you know that I have overcome the no-spaces limitation by introducing a pseudo-entity <tt>&sp;</tt> which is used by the extension to create a space where the users wants it.

DPL automaticaly creates surrounding spaces for the inlinesymbol argument and therefore makes typographicaly "normal" looking lists impossible.

I'd vote for having the default set to " - " and if an inlinesymbol argument is given, it would be rendered as given without any spaces. If a space is needed, the above mentioned pseudo-entity should be used.

For those curious to test this, please patch the source (hack 0.6) as follows:
<pre>
Change line 870 from:
$this->sEndItem = ' ' . $inlinesymbol . ' ';

to:
$this->sEndItem = str_ireplace("&sp;"," ",$inlinesymbol);
</pre>

I've tested it in my own environment and it works just fine. So if there's agreement about usefulness, why not incorporate it in Hack 0.6.1 ;)

Thanks for creating such a nice extension, BTW.

--[[User:Kaeptn00|Kaeptn00]] 16:17, 20 August 2006 (UTC)

:''Indeed. This comment suggested a feature of '''v0.6.1''', but with a larger objective: 'inlinesymbol' is replaced by 'inlinetext' which takes any wiki text. In particular, if you want spaces, use '&nbsp;' as much as needed like in wiki or HTML. (No need of something new in that case.) --[[User:Dangerman|Dangerville]] 14:26, 24 August 2006 (UTC)''

==== All namespaces, All categories ====
Is it really necessary to have ''You need to include at least one category or specify a namespace!'' error message? The number of returned articles is limited anyway. And in small wikis, there may be a good reason to list all recently modified articles, e.g. for an export list:
<pre>
<DynamicPageList>
ordermethod=lastedit
addeditdate=true
order=descending
</DynamicPageList>
</pre>

--[[User:Jsimlo|jsimlo]] 14:02, 21 July 2006 (UTC)
:''In v0.6, this is now allowed and does not generate an error, you just get a warning that you can suppress with <code>debug=1</code> (quiet mode, no warning). Reason for a warning: with no specified category or namespace, you can get ALL the pages on your mediawiki (in the order specified), which includes more than '''1400 pages''' created by default with the installation of MediaWiki (most of which are in the MediaWiki namespace I believe). This may be quite resource-consuming. But true is this is up to the user to decide. --[[User:Dangerman|Dangerville]] 23:22, 18 August 2006 (UTC)''

==== Group by user ====
This extension is almost what is being requested at [[en:Wikipedia:Administrators' noticeboard#image deletion]], except that it also needs to be able to group by the user who created the article. You could have a parameter groupby=creator|lasteditor|categoryadder. Instead of grouping, it would probably be enough to add these as additional values for ordermethod, perhaps allowing a sub-order as well. [[User:Bovlb|Bovlb]] 07:20, 20 September 2005 (UTC)
:''As of now, I'm afraid MediaWiki does not allow any reliable way to get the user that creates a specific category link in a page, if there is any. I guess some changes in the core of MediaWiki would be necessary, so something like 'groupby=categoryadder' - as you suggest - goes beyond the scope of this extension.

==== notnamespace ====
Is there a chance to add a notnamespace parameter?
I have already added the code to my own copy of DPL2, but i have no access to the svn to contribute there.
:''If you want SVN commit access, contact [[User:Brion|Brion Vibber]] and read http://www.mediawiki.org/wiki/Subversion''

Preparations:

$aNamespaces = array();
$aExcludeNamespaces = array();

Parsing parameters:

case 'namespace':
... ...
case 'notnamespace':
$sArg=trim($sArg);
$sNS = $wgContLang->getNsIndex($sArg);
if ( $sNS != NULL )
$aExcludeNamespaces[] = $sNS;
elseif (intval($sArg)>=0)
$aExcludeNamespaces[] = intval($sArg);
break;

// Namespace IS ...
... ...
// Namespace IS NOT ...
if ( !empty($aExcludeNamespaces)) {
$sSqlWhere .= ' AND (page_namespace NOT IN ( ' . implode (",", $aExcludeNamespaces) . ' ) ) ';
}

:''Feature now available (using your code + small change to error handling so that notnamespace param can be used alone) in v0.5.1. Thanks. --[[User:Dangerman|Dangerville]] 02:54, 16 July 2006 (UTC)''

==== Date and Time ====
Using addfirstcategorydate=true

23:10, 10 November 2006: NDSNews:2006-11-10 - Mathomatic ported to the DS (again)

line 1129 "$r .= $wgLang->timeanddate($article->mDate, true) . ': ';" We can change to $wgLang->date will show 10 November 2006: NDSNews:2006-11-10 - Mathomatic ported to the DS (again)

Should be easy enough to tweak :)

==== Page browse ====
Allow pages so that even with a limit on the number of articles displayed, users may click to go to the next page. This is most easily accomplished by including an "offset" attribute. However, it is probably best accomplished with a dynamic offset such that the same page can handle many different offsets which are inputted by GET in the URL.

==== DPL v0.5.1 ====
I'm running a fairly small MediaWiki 1.7.1 and the following simple list I need works without problems (can't comment on the rest of the options though, but they seemed to work fine as far as tested) ~gandm:
<pre>
<DPL>

==Where to get it?==
The download links on the page seems to be not working right now. Is there an alternative location, from which to obtain the files? --[[User:Morten Blaabjerg|MortenB]] 14:14, 26 August 2006 (UTC)
:An alternative location is now available. See [[DynamicPageList2#Source_and_Installation|Source_and_Installation]]. --[[User:Dangerman|Dangerville]] 19:22, 5 September 2006 (UTC)

== Request for comment at English Wikipedia ==

There is a discussion at the English Wikipedia about [[w:en:Wikipedia:Category intersection|a proposal to add the ability to create category intersections]]. It looks like DynamicPageList2 could be used to implement a good part of the proposal. We'd appreciate the feedback of any of the developers of DynamicPageList2. Thanks. -- [[User:SamuelWantman|SamuelWantman]] 21:03, 30 August 2006 (UTC)
:OK. --[[User:Dangerman|Dangerville]] 15:43, 3 September 2006 (UTC)

==Questions==

=== Error with adduser ===

When I use adduser = true like this

<pre>
<DPL>
category = Help
ordermethod = firstedit
order = ascending
resultsheader = <h2>Some title:</h2>
shownamespace = false
addeditdate = true
mode = ordered
adduser = true
</DPL>

</pre>

I get this error:

<pre>
Notice: Undefined property: stdClass::$mTitle in

</pre>

Am I doing something wrong? Is it a bug? --[[User:Fernandoacorreia|Fernandoacorreia]] 19:21, 14 February 2007 (UTC)

:: No you are not doing wrong. You ran into a bug. Thank you for reporting. I fixed it and uploaded the new source (0.9.1) to the dpldemo website. You can now also find an [http://semeb.com/dpldemo/index.php/Example_3 example] which shows the correct result now. [[User:Algorithmix|Algorithmix]] 22:58, 14 February 2007 (UTC)

=== List count ===

I'm not seeing a list count on any of the lists created with DynamicPageList2. Have I missed an option or does that not work with MW 1.6.5 and DPL2 0.6.3 combo? [[User:John Stanton|John Stanton]] 21:25, 12 September 2006 (UTC)

: See [[Talk:DynamicPageList2#List_Count_in_Header|List Count in Header]].

==Heading Help==
I am having problems with the heading method. It is my understanding that the following should be correct:

{|cellspacing='10'
|
'''This Code:'''
|
'''Should yield this:'''
|-
|valign='top'|
<pre>
<DPL>
category=Cat 1|Cat 2
ordermethod=category,title
headingmode=definition
mode=ordered
</DPL>
</pre>
|valign='top'|
<pre>
<dl>
<dt>Cat 1</dt>
<dd>
<ol>
<li>Page1</li>
<li>Page2</li>
</ol>
</dd>
<dt>Cat 2</dt>
<dd>
<ol>
<li>Page1</li>
</ol>
</dd>
</dl>
</pre>
|}

However, what I actually get is a listing of all the pages in Cat 1 and 2 sorted according to ALL of the other categories those pages are in. So every category that Page 1 and Page 2 are in, also show up on the list. This makes the list basically unusable.
<pre>
<dl>
<dt>A different cat</dt>
<dd>
<ol>
<li>Page1</li>
<li>Page2</li>
</ol>
</dd>
<dt>Cat 1</dt>
<dd>
<ol>
<li>Page1</li>
<li>Page2</li>
</ol>
</dd>
<dt>Cat 2</dt>
<dd>
<ol>
<li>Page1</li>
</ol>
</dd>
<dt>Another cat</dt>
<dd>
<ol>
<li>Page1</li>
<li>Page2</li>
</ol>
</dd>
</dl>
</pre>

:''The result you just described was expected and intended, as strange as it might seem. The reasons:''
:# ''The developer's excuse: in the way I implemented it, to allow as much flexibility as I could, it happens to be easier to let the DPL show headings for all categories that the page may be in (less complex SQL query) - provided the page is in Cat1 or Cat2 in your example of course - than restrict the category headings only to the categories specified with the 'category' parameter (your Cat1 and Cat2). But that's mostly a coder's reason, therefore a bad reason for the user. Maybe I did not make myself clear anyway...''
:# ''In the way I see it, the 'category' parameter is just a filter. Once the pages have been filtered with it, we forget about the filter and we play with the pages we have left like we want. I mean we should be able to give it any format (ideally) and if we want category headings, we should be able to have all the categories the filtered pages link to (no matter what). No limit. You can also view it in your example as the list of all the intersections of categories with the Cat1-union-Cat2.''

:''Despite all this blabla, I understand that the result might be unusable to you (and many others), so I'll think of an option to have that right in the next version.'' --[[User:Dangerman|Dangerville]] 21:20, 25 September 2006 (UTC)

::'''Thanks.''' That makes sense. I will look forward to any updates later.

The problem is now solved in '''v0.7.7''' by using '+' with the [[DynamicPageList2#category|category]] parameter. So in your example, you would have a slight difference (the '+' to say this list gives the headings):
<pre>
<DPL>
category=+Cat 1|Cat 2
ordermethod=category,sortkey
headingmode=definition
mode=ordered
</DPL>
</pre>
Something like this '+' is a way to tell DPL2 which category line is used for headings, since you can use the category parameter more than once. See the [[DynamicPageList2#category|doc]]. --[[User:Dangerman|Dangerville]] 15:39, 1 October 2006 (UTC)
:After updating and trying this method, I now get this error:
<pre>
%DPL2-0.7.7-WARNING: Wrong 'ordermethod' parameter: 'category,title'! Using default: 'title'.
Help: ordermethod= category,firstedit | category,lastedit | category,pagetouched | category,sortkey
| categoryadd | firstedit | lastedit | pagetouched | title | user,firstedit | user,lastedit.
</pre>

:''Indeed, as said in [[DynamicPageList2#ordermethod]], the 'category,title' ordermethod has been replaced in 0.7.7 with 'category,sortkey' to satisfy a feature request for more flexibility and reuse of sortkeys in category tags. This has the same effect as the old 'category,title' when no sortkey is defined (the full title is simply used as the sortkey).'' --[[User:Dangerman|Dangerville]] 12:22, 12 November 2006 (UTC)

== categoryadd restriction ==

Dangerman, thank you for taking my old extension and making it so much more useful. I want to deploy DPL2 on Wikinews instead of (in addition to) the old DynamicPageList. The only change that I don't understand is why there's a restriction on only allowing ordermethod=categoryadd when there is exactly one category included? The original design was just to order the output based on the date of addition to the first category mentioned. If you don't disagree, I'll add that feature back in. -- [[User:IlyaHaykinson|IlyaHaykinson]] 05:03, 1 November 2006 (UTC)

:To tell the truth, I can't recall. (Maybe it was already the case in the v0.3.3 I got from Unendlich, but it is no longer available so I can't check and I may be wrong.) I think I made this change because for instance, if you have a union of categories like <code>category= Cat1 | Cat2</code>, you can't sort the pages that are in Cat2 but not in Cat1. So what to do with these? One solution - extreme I admit - is to do the restriction you mentioned. We could also allow only intersections of categories with 'ordermethod=categoryadd'. '''If you want to remove the restriction and propose another solution, go ahead, no problem.''' Last, I added 'ordermethod=category,categoryadd' to the todo list. This would do like 'ordermethod=category,firstedit' for example, but using the date of addition to the category (not only the first one but each of them specified), instead of the first edit. The problem would be over. --[[User:Dangerman|Dangerville]] 16:07, 9 November 2006 (UTC)

==Category Intersections==
Does anyone know how they've created this [http://isaacnewton.princeton.edu/index.php/Special:CategoryQuery CategoryQuery Special Page] over at the [http://isaacnewton.princeton.edu Princeton University QED website]? It makes it really easy to do category intersections and appears to use DPL.--[[User:Weakmassive|Weakmassive]] 15:30, 4 November 2006 (UTC)

== New features ==

Hi, ive added two new features: [[User:Joschua/DynamicPageList2.php|Source and diff]] (Originating from [http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/DynamicPageList2/DynamicPageList2.php?revision=17568])
=== Display TOC ===
It Displays also the TOC as sub-items if mode is unordered or ordered.
Syntax:
<DPL>
toc=true
</DPL>
=== Search and Replace ===
It allow replacing text in the Page Title.
Example:
<DPL>
search=/FAQ:/|/foo/i
replace=|baar
</DPL>
This Example should Replace "FAQ:" through nothing, and foo or FoO through baar.

Hope you like it! --[[User:Joschua|Joschua]] 00:17, 1 December 2006 (UTC)

==File Cache Issue==
DPG2 has issues with file caching because the file cache is only updated when a user saves/updates the page itself
the DPG list/data contained is frozen to the time/date of the updated page and updated cache.

While DPG2 seems to "disable cache" in the code but doesn't stop mediawiki 1.8 from creating the cache file nor does it force it to update the cache.

* finding a trigger to stop the creation or stop the cache from being made (not the best idea if you need file caching working!)
* find a way to update cache that is over 1-24 hours old would be great because the caching system would still be active and data wouldn't be outdated for more then the set period of time

I've tried a crontab to delete the cache every 15 minutes BUT crontabs don't seem to like
* "rm /cache/e/ea/Wii%2FNews.html"
* as it will error "rm: cannot remove `/cache/e/ea/Wii': No such file or directory"

:The "%2F" is probably a URLencoded character (%2f is equivalent to a "slash"), so you might want to try "rm /cache/e/ea/Wii/News.html"
:Hope it helps. -- Algorithmix

:: Nope :( - the slash is obviously picked up by the shell as a directory not a file lable. - Any other ideas?

== New Years broke DPL2! ==

Check it out:
http://ddo.enterwiki.net/page/Home
http://ddo.enterwiki.net/page/Special:Recentchanges

The pages appearing in the recentchanges list on the side weren't actually edited since early last year! Odd. (You can reach me at my [http://ddo.enterwiki.net/page/User_talk:Peerless user talk page])

==Problems with sortkey==

I'm trying to sort a list by using "ordermethod=category,sortkey", but I get an error :
<pre>
A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "". MySQL returned error "1267: Illegal mix of collations (latin1_bin,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation 'ifnull' (internal-db.s2603.gridserver.com)".

== Number of Columns ==

I'm trying to get a multi-column list that looks like category pages sans the alphabetical headers, but I can't quite figure how to do that. Also, is there way I can specify the number of columns? —[[User:Sledged|Sledged]] 02:14, 1 February 2007 (UTC)

:: Version 0.9 of DPL2 has a new parameter "columns=" which does what you are asking for. See [http://semeb.com/dpldemo], at "other Examples". [[User:Algorithmix|Algorithmix]] 06:46, 13 February 2007 (UTC)

== Extension page ==

Is this the same as [[mw:Extension:DynamicPageList]]? If yes, which page is more up-to-date? --[[User:Fernandoacorreia|Fernandoacorreia]] 17:38, 14 February 2007 (UTC)

: Yes, '''it is the same'''. The most recent version of DPL is '''0.92'''. Source code and examples for this version can be found on a separate website ([http://semeb.com/dpldemo dpldemo]) where the extension is also installed. This allows interested people to see DPL live and make some experiments before they decide to install the extension on their web site. Source code of version 0.8x and earlier can be found in SVN.

==Installation issues==
(NB: I have also posted this question at DPLDEMO here [http://semeb.com/dpldemo/index.php/Talk:Manual#Installation_issues] sorry for the duplication)

Great extension that I was using on a previous version of mediawiki. Now have moved my site and upgraded to:
*Mediawiki 1.9.0
*MySQL 4.1
*DPL 0.9x
and I can't get it to work at all.

#I downloaded and copied DynamicPageList2.php from the manual page into extensions.
#added require_once("extensions/DynamicPageList2.php");

No good.. test page of
<pre>
<DPL>
category = CNS
</DPL>
</pre>
just renders <Pre><DPL> category = CNS </DPL> </pre>
as text.

tried to add Labeled Section Transclusion files with changes to localsetting.php

require_once("extensions/DynamicPageList2.php");
require_once("extensions/lst.php");
require_once("extensions/lsth.php");

==Table of Content and NOTOC==

Helo. DPL2 working fine, but __NOTOC__ does not seem to work, ie TOC still gets rendered in the first column of results.

Please demonstrate the problem you have with a small example on [http://semeb.com/dpldemo the dpldemo website]. Then I will try to help you.

--[[User:Algorithmix|Algorithmix]] 14:23, 14 March 2007 (UTC)

I am afraid you need a list of entries long enough such to generate an A, B, C etc.. TOC for the DPL entry.

See new example [http://www.radiopaedia.org/testwiki/index.php?title=Encyclopaedic_entries_for_CNS here] eventhough <pre> __NOTOC__ </pre>is on page, and successfully removes the TOC for the test headings.

This is the content of the test page.

<pre>
<DPL>
category=CNS
category=WR Ency
ordermethod=title
mode=category
</DPL>

==Test Heading 1==
==Test Heading 2==
==Test Heading 3==
==Test Heading 4==
==Test Heading 5==
==Test Heading 6==

__NOTOC__
</pre>

--[[User:BigBad256|BigBad256]] 23:13, 17 March 2007 (UTC)

You have to put the NOTOC clause into the resultsheader parameter of DPL. Then it works. Note: This is the wrong place to discuss DPL 0.9 and later (which you are using). You really should go to the dedicated [[http://Semeb.com/dpldemo dpl website]].

--[[User:Algorithmix|Algorithmix]] 18:50, 20 March 2007 (UTC)

Thanks Algorithmix, and sorry about the misplaced query.

==Ignore 'minor' edits==

Related to the earlier closed item "Supress 'minor' edits..." and minoredits parameter to ignore minor edits.

The problem is that using 'minoredits' parameter excludes such articles from the list completely, which should not be the case. To me the functionality is faulty, and this should be fixed. As illustration two cases

1. I want to create a list of articles in editing date order, yet to prevent minor edits to push such articles (minor edited) on the top, however by using minoredits parameter articles which are last time minor edited disappear from the list completely, i.e. then only some of the articles are listed, not all. So in practise this parameter can not be used for that purpose. Instead the functionality of the parameter should be such that date and thereby order is determined based on the last "normal/major" edit.

2. Often when new articles appear there is something small to fix, and the most recently edited article list uses exclude minoredits parameter. Right indication would be to use minor edit option, yet if I do, then those get thrown out of that recently edited list immediately. So in practise minor edit option can not be used (for additional minor edits) for a new article or for an article where there has just been major edits.

Please add "minoredits=ignore" (besides current "minoredits=exclude"), which works as described, i.e. uses last normal edit (non-minoredit) to determine the date/time stamp, and does not exclude the articles completely.

}}

'''DynamicPageList2''' is a Mediawiki extension developed for use on Wikinews (but not yet installed there), but it can be installed on any wiki. It allows wiki users to dynamically create lists of pages that are listed in a set of categories or namespaces using logical AND and OR.

Source code, manual and instructive examples for Release 0.9 can be found
on a '''separate [http://semeb.com/dpldemo/ dpl demo web site].'''
That release should be fairly stable now and solves practically all problems and
requests mentioned in the discussion page. You are invited to download and test.

The following describes release 0.8.

== DynamicPagelist2 vs. DynamicPageList ==
A short word to the history of this extension:
# At the beginning there was a small initial version called DynamicPageList (You may be able to find the source code and description still on [[meta:DynamicPageList|meta wiki]].
# That version was greatly improved and renamed to DynamicPageList'''2 (DPL2)'''. With DPL2 came much more freedom when generating dynamic article lists by using AND and OR with categories. Moreover, there were much more display options to set. See the [[#Usage_of_DynamicPageList2|list of improvements]]). Note that it was called DynamicPageList2 for distinction of [[meta:DynamicPageList|DPL]]. You could use both extensions at the same time, because the new tag was called <nowiki><DPL> instead of <DynamicPageList></nowiki>. ''The text you are reading describes "DPL2". Development of DPL2 came to an end around December, 2006
# Since then the source code of DPL2 was considerably improved and many more features were added. The extension now became a complete superset of the "old DPL" and "DPL2". It didn´t look very wise to call it DPL3, though. So the name was simply '''changed back''' to '''[[Extension:DynamicPageList|DynamicPageList]]'''. Some names in the source code still have a "2" in their text. You will find '''that latest version''' (which is still under active development as of April, 2008) under [[Extension:DynamicPageList]]. There is a separate [http://semeb.com/dpldemo website] where the latest release of DPL is installed and can be used for experimenting.

* [[w:User:Dangerville|Dangerville]]

==See also - similar functionality==
* [[Extension:Semantic MediaWiki]] would also allow the inclusion of the result of this kind of queries to categories ([[union of categories|union]], [[intersection of categories|intersection]]) (as well as more "[[w:Semantic Web]]" features).

==Source and Installation==

=== Get code/file ===
First download the source from (2 possible locations):
*'''svn.wikimedia.org (for latest/development version)'''
:[http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/DynamicPageList2/DynamicPageList2.php DynamicPageList2.php]: Main file.
:[http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/DynamicPageList2/DynamicPageList2.i18n.php DynamicPageList2.i18n.php]: Required by <code>DynamicPageList2.php</code>, internationalization file used for all DPL messages.
*'''Alternative location: svnweb.tuxfamily.org (for latest or older releases)
:Development version: [http://svnweb.tuxfamily.org/listing.php?repname=extensions+%28wikidpl%29&path=%2FDynamicPageList2%2Ftrunk%2F&rev=0&sc=0 Browse] - [http://svnweb.tuxfamily.org/dl.php?repname=extensions+%28wikidpl%29&path=%2FDynamicPageList2%2Ftrunk%2F&rev=0&isdir=1 Tarball]

=== Installation ===
To install it,
# put the file in your <code>extensions/</code> directory, and add
# edit to your <code>LocalSettings.php</code> file this line:
<code>require_once("extensions/DynamicPageList2.php");</code>

For '''0.8.0 and above''', you have to install the [[mw:Extension:Labeled_Section_Transclusion|Labeled Section Transclusion]] extension too (both lst.php and lsth.php files).

For '''v0.7.0 and above''', if you want to apply the [[#category|'category' parameter]] on the Uncategorized pages, you are required to execute this manual query on your MediaWiki database, '''replacing <code>prefix</code> with your prefix''' if any:
<pre>
CREATE VIEW prefix_dpl_clview AS
SELECT IFNULL(cl_from, page_id) AS cl_from, IFNULL(cl_to, '') AS cl_to, cl_sortkey
FROM prefix_page LEFT OUTER JOIN prefix_categorylinks ON page_id=cl_from
</pre>

If you are using this extension with [[:en:Internet Information Services|IIS]] on a Windows box, make sure to give Read & Execute rights to the user IUSR_MACHINENAME (Anonymous Internet Guest Account) for the extensions directory and the DynamicPageList2.php file itself.

==System requirements==
* DPL2 0.8.0 and above: '''MediaWiki 1.8.2''' or above, and both lst.php and lsth.php files from '''[[mw:Extension:Labeled_Section_Transclusion|Labeled Section Transclusion]]'''.
* DPL2 0.7.8 and above: if using MySQL, '''MySQL 4.1''' or above is required for firstedit/lastedit sorts (because these use nested queries of the form SELECT ... SELECT ..., see also [http://dev.mysql.com/doc/refman/4.1/en/rewriting-subqueries.html MySQL 3.23, 4.0, 4.1 Reference Manual :: 13.2.8.11 Rewriting Subqueries as Joins for Earlier MySQL Versions]).
* DPL2 0.7.0 and later: if you want to use the 'category' parameter on Uncategorized pages (empty string) with a MySQL server, '''MySQL 5.0.1''' or above is required (the creation of the dpl_clview requires the CREATE VIEW statement, see also [http://dev.mysql.com/doc/refman/5.0/en/create-view.html MySQL 5.0 Reference Manual :: 19.2 CREATE VIEW Syntax]).
* DPL2 0.6 and later: '''MediaWiki 1.7.1''' or above for internationalization. ([http://mail.wikipedia.org/pipermail/mediawiki-i18n/2006-June/000096.html more info...]).
* DPL2 0.5.1: See [[{{TALKPAGENAME}}#MediaWiki_1.7.x|test on '''MediaWiki 1.7''']] by gandm.
* DPL2 0.5.x: Tested (mostly) successfully on '''Mediawiki 1.6.7'''.
Not compatible with '''Mediawiki 1.5.x'''.
The extension uses (needs) more than two parameters and WikiMedia 1.5.x provides only two.

== Usage of DynamicPageList2 ==

To use DPL, use the following XML-like syntax on your wiki page:

<pre>
<DPL>
...parameters...
</DPL>
</pre>

The output of this would be something like: (depending on the outputmode you select)

* [[Page 1]]
* [[Page 2]]
* [[Another Page]]

You can nest DPL in a static list on your wiki page:
<pre>
<ul>
<li>Item1</li>
<li>Item2
<DPL>
...parameters...
</DPL>
</li>
</ul>
</pre>

The list of pages being output, as well as the order and display mode of the list has to match the defined parameters.

The following lists parameters and their effects

===category===

Purpose:

Include pages in the union of given categories. You can specify more than one category with the pipe '|' as a separator, with the effect that the pages listed have to be at least in one of the categories (logical OR).
If you specify the 'category=' parameter more than once, the pages listed have to match all these parameters (logical AND).

Syntax:

<code>category=1st category name|2nd category name|3rd category name|...</code>

Example 1:

<pre>
<DPL>
category=Africa|Europe
category=Politics and conflicts
</DPL>
</pre>

This list will output pages that have <nowiki>[[Category:Africa]] OR [[Category:Europe]], AND [[Category:Politics and conflicts]]</nowiki> listed.

'''v0.7.0''' - You can specify the set of [[Special:Uncategorizedpages|Uncategorized]] pages as a normal category, with an empty string (e.g. '<code>category=</code>' for uncategorized pages only, '<code>category=|Animals</code>' or '<code>namespace=Animals|</code>' for the Uncategorized or the Animals category, '<code>category=Mammals||Insects</code>' for the Mammals category, uncategorized pages or the Insects category, etc.). See [[#Source_and_Installation|Source and Installation]] for the extra required installation steps.

'''v0.7.7''' - If [[#ordermethod|ordermethod]]=category,... and [[#headingmode|headingmode]] are enabled, you can restrict the categories you want as headings in the result by preceding the list of categories (specified with the category parameter) with a '+'. See the example below.

Example 2:

<pre>
<DPL>
category=+Africa|Europe
category=Politics and conflicts
ordermethod=category,sortkey
headingmode=ordered
</DPL>
</pre>

This list will output pages that have <nowiki>[[Category:Africa]] OR [[Category:Europe]], AND [[Category:Politics and conflicts]]</nowiki> listed. The list will be ordered (OL tag) and organized in 2 main items/headings: the ''Africa'' one and the ''Europe'' one (''Politics and conflicts'' will not be used as a heading). Under each item/heading, a sublist of pages ordered by their sortkey for the category used as heading.

Notes:

You may use [[m:Help:Magic words|Magic words]] like <nowiki>{{CURRENTMONTHNAME}}, {{CURRENTDAY}}, {{CURRENTYEAR}}</nowiki> etc in the category name, as long as they do not contain the character "|".

Related extension variables ([[#Extension_options|more info]]): <code>$wgDPL2MaxCategoryCount</code>, <code>$wgDPL2AllowUnlimitedCategories</code>, <code>$wgDPL2MinCategoryCount</code>.

===notcategory===

Purpose:

Much like the category parameter, but requires that every page listed ''not'' be in a particular category. Unlike in 'category' you cannot combine several categories using logical OR in this parameter.

Syntax:

<code>notcategory=category name</code>

Example:

<pre>
<DPL>
category=Africa
notcategory=Zimbabwe
notcategory=Kenya
</DPL>
</pre>

This list will output pages that have <nowiki>[[Category:Africa]]</nowiki> but ''do not'' have either <nowiki>[[Category:Zimbabwe]]</nowiki> or <nowiki>[[Category:Kenya]]</nowiki> listed.

Notes:

You may use [[m:Help:Magic words|Magic words]] like <nowiki>{{CURRENTMONTHNAME}}, {{CURRENTDAY}}, {{CURRENTYEAR}}</nowiki> etc in the category name.

Related extension variables ([[#Extension_options|more info]]): <code>$wgDPL2MaxCategoryCount</code>, <code>$wgDPL2AllowUnlimitedCategories</code>, <code>$wgDPL2MinCategoryCount</code>.

===namespace===

Purpose:

To restrict the articles in the list to only be in one of the given namespaces.

'''v0.7.7''' - Magic words supported. See [[m:Help:Magic words#Page_names_and_related_info]] and [[m:Help:Magic words#Namespaces_and_URLs]] for relevant magic words.

Syntax:

<code>namespace=1st namespace name|2nd namespace name|3rd namespace name|...</code>

The namespace name may be anyone, assuming it represents a valid namespace in the system, including custom ones, BUT no pseudo-namespace such as ''Media'', ''Special'' which have negative namespace ids. See [[m:Help:Namespace]]. The empty string is the main article namespace (e.g. '<code>namespace=</code>' for pages in Main ns only, '<code>namespace=|Help</code>' or '<code>namespace=Talk|</code>' for Main or Talk ns, '<code>namespace=User||Category</code>' for User, Main or Category, etc.).

Name spaces are case sensitive <code>namespace=User_talk</code> will work, but <code>namespace=User_Talk</code> will not.

:''Namespace ids are no longer allowed as namespace arguments, because it caused a conflict between namespace given a number as name on one hand, and namespace with that same number as namespace id on the other hand. E.g. if you created a custom namespace with '1' as title (yes, it's possible), <code>namespace=1</code> would give you pages in '1' and not pages in namespace with id=1 (''Talk''). In that case, you could not get pages in the Talk ns anymore. Solution: use only ids or only names. Names are more user-friendly.''

Example 1:

<pre>
<DPL>
category=Policy
namespace=Wikinews|Discussion
</DPL>
</pre>

This list will output pages that are in the ''Wikinews'' or ''Discussion'' namespace and belong to <nowiki>[[Category:Policy]]</nowiki>.

Example 2 (with magic word):

<pre>
<DPL>
category=Policy
namespace={{NAMESPACE}}
</DPL>
</pre>

This list will output pages that are in the namespace the current page is in - whatever it is - and belong to <nowiki>[[Category:Policy]]</nowiki>.

===notnamespace===

Purpose:

Much like the notcategory parameter, but for namespaces. Requires that every page listed '''not''' be in one of given namespaces.

'''v0.7.7''' - Magic words supported. See [[m:Help:Magic words#Page_names_and_related_info]] and [[m:Help:Magic words#Namespaces_and_URLs]] for relevant magic words.

Syntax:

<code>notnamespace=namespace name</code>

Example 1:

<pre>
<DPL>
notnamespace=Wikinews
notnamespace=Discussion
</DPL>
</pre>

This list will output pages that are NEITHER in the ''Wikinews'' NOR in the ''Discussion'' namespace.

Example 2 (with magic word):

<pre>
<DPL>
notnamespace=Wikinews
notnamespace={{NAMESPACE}}
</DPL>
</pre>

This list will output pages that are NEITHER in the ''Wikinews'' NOR in the namespace the current page is in.

===linksto===
Introduced in '''v0.7.7'''.

Purpose:

Filters the articles which link to a certain page. Magic words are supported. See [[m:Help:Magic words#Page_names_and_related_info]] for relevant magic words.

Syntax:

<code>linksto=full page name</code>

Example 1:
<pre>
<DPL>
category=Poets
linksto=Dublin
</DPL>
</pre>

This list will output pages that are in category "Poets" and link to the page with title ''Dublin'' in the Main namespace.

Example 2 (with magic word):

<pre>
<DPL>
category=Poets
linksto={{FULLPAGENAME}}
</DPL>
</pre>

This list will output pages that are in category "Poets" and link to the current page, whatever it is.

===shownamespace===

Purpose:

To restrict the appearance of the namespace name of a page before the page. For example, when this parameter is used, instead of Template:Stub the listing would simply be Stub.

Example:

<code>shownamespace=false</code>

If omitted, the default is ''true''.

Example:

<pre>
<DPL>
category=Africa
namespace=Talk
shownamespace=false
</DPL>
</pre>

This list will output all Talk pages in <nowiki>[[Category:Africa]]</nowiki>, listed without the Talk: prepended to page names.

===mode===

Purpose:

To control the output of the DPL.

Syntax:

<code>mode=modename</code>

''modename'' can be one of:
* ''unordered'' — outputs an unordered list — HTML tag "ul" — '''(default)'''
* ''ordered'' — outputs an ordered list — HTML tag "ol"
* ''none'' — outputs a list using newlines and HTML tags "br" to separate each item
* ''inline'' — outputs a list using symbol defined by the [[#inlinetext|inlinetext parameter]] to separate items. See [[#inlinetext|inlinetext]] for more info.
* ''category'' — outputs resulting articles in a way category-pages are shown ('''you have to use <code>ordermethod=title|category,title|user,title</code> with this option!''')

Example:

<pre>
<DPL>
category=Africa
mode=ordered
</DPL>
</pre>

This list will output pages that have <nowiki>[[Category:Africa]]</nowiki> shown in an <ol>...</ol> list.

Related extension variable(s): <code>$wgDPL2CategoryStyleListCutoff</code>.

===inlinetext===
''This replaced 'inlinesymbol'''.

Purpose:

To define the inline text used in <code>mode=inline</code>.

Syntax:

<code>inlinetext=wikitext</code>, with wikitext some wiki text, '''default is '&nbsp;-&nbsp;''''.

'''Extra whitespaces are stripped by DPL from the beginning and end of wikitext. If you want to show one or multiple spaces, use one or multiple '<code>&nbsp;</code>', or use 'nowiki' tags like in '<nowiki> - </nowiki>' which has same effect as '&nbsp;-&nbsp;'.'''

Example:

<pre>
<DPL>
category=Africa
mode=inline
inlinetext=&nbsp;&bull;&nbsp;
</DPL>
</pre>

This list will output pages that have <nowiki>[[Category:Africa]]</nowiki> shown like Item1 • Item2 • Item3 • ...

===headingmode===

Purpose:

To control the output of the headings in a DPL with complex/multi-parameter [[#ordermethod|ordermethods]]. (No effect with single-param ordermethods.) For <code>ordermethod=method1,method2,...</code>, method1 is used for headings. E.g. <code>headingmode</code> affects category headings in <code>ordermethod=category,title</code> (2-param ordermethod).

Syntax:

<code>headingmode=modename</code>

''modename'' can be one of:
* ''none'' — headings are not displayed, no heading — '''(default)'''
* ''unordered'' — outputs an unordered list — HTML tag "ul"
* ''ordered'' — outputs an ordered list — HTML tag "ol"
* ''definition'' — outputs a definition list — HTML tag "dl"
* ''H2'' — outputs sections — HTML tags "H2"
* ''H3'' — outputs sections — HTML tags "H3"
* ''H4'' — outputs sections — HTML tags "H4"

Example:

<pre>
<DPL>
category=Africa|Europe
ordermethod=category,title
headingmode=definition
mode=ordered
</DPL>
</pre>

This list will output pages that belong to one of the categories Africa, Europe in a list similar to this (HTML source), with Pages 1 and 2 in the Africa category, Page 1 in the Europe category as well (in fact, the titles are replaced with the appropriate links):
<pre>
<dl>
<dt>Africa</dt>
<dd>
<ol>
<li>Page1</li>
<li>Page2</li>
</ol>
</dd>
<dt>Europe</dt>
<dd>
<ol>
<li>Page1</li>
</ol>
</dd>
</dl>
</pre>

===titlemaxlength===
Purpose:

To limit the number of characters of the title to display. If the page title (this does not include the namespace or any other prefix before the title) is bigger than the titlemaxlength value, the title is truncated and ended by '...'.

Syntax:

Same syntax as the [[#count|count]] parameter.

===order===

Purpose:

Controls the sort direction of the list.

Example:

<code>order=orderdirection</code>

''orderdirection'' can be one of:
* ''descending'' — outputs list from most recent to least recent — '''(default)'''
* ''ascending'' — outputs list from least recent to most recent

Example:

<pre>
<DPL>
category=Africa
order=ascending
</DPL>
</pre>

This list will output pages that have <nowiki>[[Category:Africa]]</nowiki> shown ordered from oldest to newest.

===count===

Purpose:

Controls the number of results that are shown.

Syntax:

<code>count=n</code>, with <code>n</code> a positive integer

A blank value (<code>count=</code>) for unlimited. '''It is unlimited by default''', depending on [[#Extension_options|extension variables]]: <code>$wgDPL2MaxResultCount</code>, <code>$wgDPL2AllowUnlimitedResults</code>.

Example:

<pre>
<DPL>
category=Africa
ordermethod=pagetouched
count=2
</DPL>
</pre>

This list will output the two pages most recently changed that have <nowiki>[[Category:Africa]]</nowiki>.

===ordermethod===

Purpose:

Determines what criterium (resp. criteria) is (resp. are) used to order the list.

Syntax:

<code>ordermethod=method1,method2,...</code> means ordered by method1 first, then by method2, etc. (like the ORDER clause in SQL)

''methodN'' can be one of:
* ''categoryadd'' — outputs list based on most recent addition to the first category (requires to include one category and one only using 'category' parameter)
* ''counter'' — outputs list based on the number of times the page has been viewed (by ~popularity)
* ''firstedit'' — outputs list based on first edit to the pages (creation)
* ''lastedit'' — outputs list based on most recent edit to the pages
* ''pagetouched'' — outputs list based on 'page_touched' timestamp. Read comment on <code>page_touched</code> field in [[mw:Page_table|Page_table]] to see the difference from most recent edit by an author.
* ''title'' — outputs list sorted by article (prefix +) title — '''(default)'''
Multi-param ordermethods (see also [[#headingmode|''headingmode'']] option):
* ''category,firstedit'' — outputs list sorted by category, then by first edit
* ''category,lastedit'' — outputs list sorted by category, then by last edit within a category
* ''category,pagetouched'' — outputs list sorted by category, then by pagetouched
* ''category,title'' — outputs list sorted by category, then by title
: Replaced by ''category,sortkey'' in '''v0.7.7''' to customize the order with sortkeys from category tags, like in MediaWiki category pages.
* ''user,firstedit'' — outputs list sorted by user, then by firstedit by the user
* ''user,lastedit'' — outputs list sorted by user, then by lastedit by the user

Example:

<pre>
<DPL>
category=Africa
ordermethod=lastedit
</DPL>
</pre>

This list will output pages that have <nowiki>[[Category:Africa]]</nowiki> showing most recently edited articles at the top.

===debug===

Purpose:

Sets debugging level.

Syntax:

<code>debug=n</code>, where ''n'' is one of:
*''0'' — silent mode, shows nothing
*''1'' — quiet mode, shows (fatal) errors
*''2'' — default mode, like 1 + shows warnings; — '''(default)'''
*''3'' — verbose mode, like 2 + shows SQL query.
'''If you use debug param but not in first position in the DPL element, the new debug settings are not applied before all previous parameters have been parsed and checked.''' This will generate a warning for <code>debug=2</code> and above.

Example:

<pre>
<DPL>
namespace=Media
debug=0
namespace=Special
</DPL>
</pre>

This list will output the error for the first namespace: ''Media'' is not a valid [[#namespace|namespace]] value (pseudo-namespace). Assuming you haven't changed the default debug value (2), you will also get a warning: <code>debug=1</code> is not input first (before <code>namespace=Media</code>). So it did not apply to <code>namespace=Media</code> but only to what's after. Indeed, you won't get the warning for the second namespace (''Special'') since <code>debug=0</code> changed debug settings to silent mode.

DPL debug messages are translatable in <code>DynamicPageList2.i18n.php</code>. See also [[#Internationalization|Internationalization]].

===minoredits===

Purpose:

Controls the inclusion or exlusion of minor edits in lists.

Requires: ordermethod=[...]firstedit|lastedit

Example:

<code>minoredits=criteria</code>

''criteria'' can be one of:
* ''exclude'' — ignore minor edits when sorting lists
* ''include'' — includes minor edits to sort lists — '''(default)'''

Example:

<pre>
<DPL>
category=Africa
ordermethod=lastedit
minoredits=exclude
</DPL>
</pre>

This list will order pages tagged with <nowiki>[[Category:Africa]]</nowiki> by lastedit, but minor edits will be ignored in the ordering.

===redirects===

Purpose:

Controls the inclusion or exlusion of redirect pages in lists.

Example:

<code>redirects=criteria</code>

''criteria'' can be one of:
* ''exclude'' — excludes redirect pages from lists — '''(default)'''
* ''include'' — allows redirect pages to appear in lists
* ''only'' — lists ''only'' redirect pages in lists

Example:

<pre>
<DPL>
category=Africa
redirects=include
</DPL>
</pre>

This list will content pages and redirect pages tagged with <nowiki>[[Category:Africa]]</nowiki>.

===addfirstcategorydate===
Requires to include one and one category only, with 'category' parameter.

Conflicts with other "add*date" (addeditdate, etc.) parameters to avoid confusion.

Purpose:

Shows the date/time the article got added to the first listed include category.

Example:

<code>addfirstcategorydate=true</code>

If omitted, the default is ''false''.

Example:

<pre>
<DPL>
category=Africa
addfirstcategorydate=true
</DPL>
</pre>

This list will output a list of pages belonging to <nowiki>[[Category:Africa]]</nowiki>, prepending each result with the time and date (formatted according to your local mediawiki date display preferences or the user preferences if user logged in).

===addeditdate===
Requires ordermethod=[...,]firstedit or ordermethod=[...,]lastedit. ([...,] means complex ordermethods with extra param before firstedit|lastedit are allowed.)

Conflicts with other "add*date" (addpagetoucheddate, etc.) parameters.

Purpose:

If firstedit (resp. lastedit), 'addeditdate=true' shows the date of the first revision/creation (resp. last revision) of the page.

Example:

<code>addeditdate=true</code>

If omitted, the default is ''false''.

Example:

<pre>
<DPL>
category=Africa
ordermethod=lastedit
addeditdate=true
</DPL>
</pre>

This list will output a list of pages belonging to <nowiki>[[Category:Africa]]</nowiki>, prepending each result with the date of last revision (formatted according to your local mediawiki date display preferences or the user's preferences if logged in).

===addpagecounter===

Purpose:

Shows number of times the page has been viewed according to the definition of the 'page_counter' field on [[mw:Page_table|Page_table]].

Example:

<code>addpagecounter=true</code>

If omitted, the default is ''false''.

===addpagetoucheddate===
Requires ordermethod=[...,]pagetouched or ordermethod=[...,]title. ([...,] means complex ordermethods with extra param before are allowed.)

Purpose:

Shows date/time of last change to the page according to the definition of the 'page_touched' field on [[mw:Page_table|Page_table]].

Example:

<code>addpagetoucheddate=true</code>

If omitted, the default is ''false''.

Example:

<pre>
<DPL>
category=Africa
ordermethod=pagetouched
addpagetoucheddate=true
</DPL>
</pre>

This list will output a list of pages belonging to <nowiki>[[Category:Africa]]</nowiki>, prepending each result with the date of last change (formatted according to your local mediawiki date display preferences or the user's preferences if logged in).

===adduser===
Requires ordermethod=[...,]firstedit or ordermethod=[...,]lastedit. ([...,] means complex ordermethods with extra param.)

Purpose:

If firstedit (resp. lastedit), 'adduser=true' shows the name of the user who made the last revision (resp. last revision) of the page.

Example:

<code>adduser=true</code>

If omitted, the default is ''false''.

Example:

<pre>
<DPL>
category=Africa
ordermethod=lastedit
adduser=true
</DPL>
</pre>

This list will output a list of pages belonging to <nowiki>[[Category:Africa]]</nowiki>, prepending each result with the author of the last revision.

--[[User:139.76.128.68|139.76.128.68]] 17:27, 19 July 2007 (UTC)
===includepage===
Purpose: include pages (whole content) or include labeled sections.

Requires <code>lst.php</code> from [[mw:Extension:Labeled_Section_Transclusion|Labeled Section Transclusion]]

Syntax:
* To include the whole page, use a wildcard:
:<code>includepage=*</code>
* To include sections labeled 'sec1' or 'sec2'... from the page (refer to [[mw:Extension:Labeled_Section_Transclusion|Labeled Section Transclusion]] to know how to label sections in your pages accordingly):
:<code>includepage=sec1,sec2,...</code>
* To include from the first occurrence of the heading 'heading1' (resp. 'heading2') until the next heading of the same or lower level. Note that this comparison is case insensitive. (Refer to [[mw:Extension:Labeled_Section_Transclusion#Transcluding_visual_headings|Transcluding visual headings]].) :
:<code>includepage = #heading1,#heading2,....</code>
* You can combine:
:<code>includepage = sec1,#heading1,....</code>
* To include nothing from the page (no inclusion), leave blank (this is '''default'''):
:<code>includepage=</code>

===secseparators===
Purpose: customize the output format of multiple transcluded labeled sections.

Syntax:

<code>secseparators=Startall,Start,End,Endall</code>

'Startall', 'Start', 'End' and 'Endall' are HTML strings used to separate the transcluded sections in the output (see [[#includepage|'includepage=name1,name2,...']]). 'Startall' and 'Endall' define an outer frame for sections of a page; 'Start' and 'End' build an inner frame for each section.
Example:
<pre>secseparators=<table><tr>,<td>,</td>,</tr></table></pre>
would output a table with all sections in a row (for every page where sections have been found).

=== listattr ===
Purpose:
Adds attributes to HTML list elements, depending on 'mode' (html element is 'ol' for ordered, 'ul' for unordered, 'div' for others). Can be used with '''pseudo''' 'mode=inline' where 'inlinetext' contains one or more <code><nowiki> </nowiki>.

Not applicable to 'mode=category' or mode='inline' (with no <code><nowiki> </nowiki> in inlinetext).

Syntax:
<code>listattr= attribute1="val1" attribute2="val2" ...</code>

|}

== Server-Wide Configuration ==
=== Extension options ===
You can set the following global variables, preferably in your <code>LocalSettings.php</code> (after including <code>DynamicPageList2.php</code>) or in <code>DynamicPageList2.php</code> directly, to configure and restrict the usage of the DPL extension server-wide.

'''$wgDPL2MaxCategoryCount'''
Maximum number of categories specified in a DPL with 'category' or 'notcategory' parameters = Maximum number of categories allowed in the SQL-query. To prevent too complex queries.

'''$wgDPL2AllowUnlimitedCategories'''
Allows unlimited categories in the query. (<code>$wgDPLMaxCategoryCount</code> will be ignored)

'''$wgDPL2MinCategoryCount'''
Minimum number of categories specified in a DPL with 'category' or 'notcategory' parameters = Minimum number of categories needed in the SQL-query for setting limits. To prevent output of a gigantic list.

'''$wgDPL2MaxResultCount'''
Maximum number of results to allow.

'''$wgDPL2AllowUnlimitedResults'''
Allow unlimited results to be shown. (<code>$wgDPLMaxResultCount will be ignored</code>)

'''$wgDPL2CategoryStyleListCutoff'''
Max length to format a list of articles chunked by letter as bullet list, if list bigger, columnar format user (same as cutoff arg for <code>CategoryPage::formatList()</code>). Used by <code>mode=category</code>.

'''$wgDPL2Options'''
Gives control on the extension parameters (see [[#Usage_of_DynamicPageList2|Usage of DynamicPageList2]] for the list). The best way to get familiar with it is to look at its declaration in <code>DynamicPageList2.php</code> (beginning). Use it at your own risk. Anyway, below are some usage examples:
* Change default parameter values: <code>$wgDPL2Options['param']['default']='val'</code>. Make sure ''val'' is a valid ''param'' value.
: Example: <code>$wgDPL2Options['shownamespace']['default']='false'</code> to change the shownamespace default value to 'false'.
* Restrict parameter options: if the parameter ''param'' has options ''option0'', ... , ''optionN'' (according to the definition of <code>$wgDPL2Options</code> in <code>DynamicPageList2.php</code>), <code>$wgDPL2Options['param'] = array('option0',...,'optionn-1','optionn+1',...,'optionN')</code> will disable ''optionn'' for users (not allowed). If you disable an option currently defined as default parameter value, make sure you change the default value to another option as well (see previous item).

=== Internationalization ===
Since MediaWiki 1.7.1, extension messages are translatable ([http://mail.wikipedia.org/pipermail/mediawiki-i18n/2006-June/000096.html more info]). To use this feature and translate the DPL messages into your favorite language, have a look at <code>DynamicPageList2.i18n.php</code>. All you have to do is to create in this file a <code>$wgDPL2Messages['lang']</code> array where 'lang' is your language code, and use <code>$wgDPL2Messages['en']</code> as a model. Replace values with appropriate translations.

Dear DPL users,

The upcoming release of MW 1.12 will contain a fundamental change in the parser.
Testing DPL with MW 1.12 has shown that the new parser will break some of DPL´s functionality.
Among others '''nested DPL queries''' and evaluation of '''parameters containing template calls''' will no longer be possible with the new parser.
For details see the [http://semeb.com/dpldemo DPL homepage].‎

'''Dynamic Page List''' (DPL) is a universal reporting tool for MediaWikis, listing category members and intersections with various formats and details. For usage documentation, see [[m:DynamicPageList]] and the [http://semeb.com/dpldemo/DPL:Manual manual]. Typically the selection of pages to be shown will be based on one or more categories. But there are many other choices for selection criteria, like e.g. author, namespace, date, name pattern, usage of templates or references to other articles.

==Overview==
Assume you have written some articles about ''countries''. Typically these articles will have three things in common:
* They will belong to a common category
* They will have a similar chapter structure, i.e. they will contain sections named 'Religion' or 'History'
* They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

===DPL generates reports on other articles===
Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on each country.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

DPL can
* generate a list of all those articles (or a random sample)
* show metadata of the articles
* show one or more chapters of the articles
* show parameter values which are passed to the common template
* order articles appropriately
* present the result in a sortable table (e.g.)
* use multi column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* select by a logical combination (AND,OR,NOT) of categories
* specify a range for the number of categories the article must be assigned to
* select by a logical combination (AND,OR,NOT) of namespaces
* define a pattern which must match the article´s name
* name a page to which the article must or must not refer
* name a template which the article must or must not use
* exclude or include redirections
* use other criteria for selection like author, date of last change etc.
* define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* name
* date of last change
* popularity
* user who changed them last
* size
* restrict the output to the first n articles or to a random sample
* use descending or ascending sequence

'''Define attributes you want to see'''
* article name
* article namespace
* article size
* date of last change
* date of last access
* user who changed them last

'''Define contents you want to show'''
* whole article
* contents of certain chapters (identified by headings)
* text portions (defined by special marker tags in the article)
* values of template calls

'''Define the output format'''
* specify a headline
* use ordered list, unordered list
* use tables, sorted tables (using javascript)
* use category style listing
* multi column output
* truncate title or contents to maximum length
* add a link to the article or to one or more of its chapters

===DPL generates reports on categories===
Apart from producing a list of pages which fit certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

===DPL extracts objects and relations for generation of graphs with [[Extension:Wgraph]]===
With DPL you can generate output which is then fed into other MediaWiki extensions. An especially useful application of this kind is graph generation. DPL can analyse your wiki and prepare output which is then used by [[Extension:Wgraph]] to visualize it.

===DPL interacts with other extensions===
There is a special mechanism which allows to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a leight-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

DPL can do much more than we can explain here. A complete '''[http://semeb.com/dpldemo/DPL:Manual manual]''' and many examples can be found on the on the separate [http://semeb.com/dpldemo DPL website].

===Closely associated extension for passing parameters to articles===
The website where DPL is offered for download also contains the ''Call'' extension which allows to call an arbitrary MediaWiki article from the command line or from a wiki link and pass parameters to the article.

===Other Application===
*[[DPL Page Name S/N Maker]]-Use this extension to create pages with serial number page names

Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on each country.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

DPL can
* generate a list of all those articles (or a random sample)
* show metadata of the articles
* show one or more chapters of the articles
* show parameter values which are passed to the common template
* order articles appropriately
* present the result in a sortable table (e.g.)
* use multi column output

===Which steps are necessary?===
'''Find the articles you want to list:'''
* select by a logical combination (AND,OR,NOT) of categories
* specify a range for the number of categories the article must be assigned to
* select by a logical combination (AND,OR,NOT) of namespaces
* define a pattern which must match the article´s name
* name a page to which the article must or must not refer
* name a template which the article must or must not use
* exclude or include redirections
* use other criteria for selection like author, date of last change etc.
* define regular expressions to match the contents of pages you want to include

'''Order the result list of articles according to'''
* name
* date of last change
* popularity
* user who changed them last
* size
* restrict the output to the first n articles or to a random sample
* use descending or ascending sequence

'''Define attributes you want to see'''
* article name
* article namespace
* article size
* date of last change
* date of last access
* user who changed them last

'''Define contents you want to show'''
* whole article
* contents of certain chapters (identified by headings)
* text portions (defined by special marker tags in the article)
* values of template calls

'''Define the output format'''
* specify a headline
* use ordered list, unordered list
* use tables, sorted tables (using javascript)
* use category style listing
* multi column output
* truncate title or contents to maximum length
* add a link to the article or to one or more of its chapters

===DPL generates reports on categories===
Apart from producing a list of pages which fit certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

===DPL extracts objects and relations for generation of graphs with [[Extension:Wgraph]]===
With DPL you can generate output which is then fed into other MediaWiki extensions. An especially useful application of this kind is graph generation. DPL can analyse your wiki and prepare output which is then used by [[Extension:Wgraph]] to visualize it.

===DPL interacts with other extensions===
There is a special mechanism which allows to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for [[Extension:Treeview]], you can create dependency graphs or timebars with [[Extension:Wgraph]], you can call 'gallery' or whatever you want...

===DPL is a platform for building other applications===
The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming.
* See for example the [[Extension:DPL Calendar]]. The advantage is that these applications can be more easily modified and localized.
* Another example is a leight-weight "semantic wiki" approach. See the [http://semeb.com/dpldemo DPL demo page] for details.

==Questions/Tips==

=== Tabbed info balloons ===

This extension has just been installed at the [[GreatLakesWiki:Main Page|Great Lakes Wiki]] ... I have been hacking around trying to understand the features. It's TRES nifty. I think maybe I'm doing something wrong with tabbed info balloons, can someone point me to a wiki/page/map that uses them so I can see if it's me interpreting the syntax wrong? Here is the code I put in on the article [[GreatLakesWiki:Thornapple River]]
<pre>

<googlemap lat="42.890555" lon="-85.475349" width="600" height="600" overview="yes">
(A) 42.953125, -85.484061 /Dam\ The [[wikipedia:Ada Township, Michigan|Ada]] dam
/Bridge\ The [[wikipedia:Ada Covered Bridge|]]
(C) 42.910297, -85.49921, The [[wikipedia:Cascade Township, Michigan|Cascade]] dam
(L) 42.883512, -85.475693, [[Wikipedia:Caledonia Township, Kent County, Michigan|Caledonia]] dam
</googlemap>
</pre>

The marker (A) which should have two tabs is not clickable, that is, the pointer does not change to a finger when you mouse over it, so no balloon comes up. A previous version (in the history) without tabs worked OK. Markers C and L work fine... do I need a comma after the coords? the helps showed it without comma... I think maybe the helps are not quite right, because when I put a comma in, it does change to a finger, but I see text with /dam\ in the balloon and no second tab... if I put nothing after the comma it changes to non fingered (only a drag grab hand) So I'm confused. :) ++[[User:Lar|Lar]]: [[User_talk:Lar|t]]/[[Special:Contributions/Lar|c]] 04:33, 30 November 2007 (UTC)

=== Using Properties from Sematic Media Wiki as coordinates? ===
Hi, I use a database with semantic media wiki. Is it possible to use properties (geographic coordinates) as input for the map? The map should center around the specified coordinate given in the porperty and show a marker.
Kai, 2007-10-31

=== Marker info from an external file ===
Any ideas on how to include the marker information (location, etc.) in an external file. I want to generate status information from several locations on the fly and then change their icons to reflect the status. Suggestions? [[User:Jspahn|Jspahn]] 26 July 2007

===Create a map link not visible?===
Be aware that changing the user_options setting showtoolbar to 0 (hiding the toolbar) will also hide your Create a Map link!

You must have toolbar turned on to see the map link.

P.Coghlan (June 12th 2007)

=== Creating Points ===

I was looking around the site here and couldn't find a way to make a point on the map without going into the "edit page". I'm looking for a way for someone to just goto the displayed map, click on a location, and make a point there. Is there any way this is possible?

=== where to change size and shadow size of custom markers? ===

Wow. Thanks for this really great extension. Easy to install, easy to use. Impressing results.

I have a question dealing with custom markers: '''when I use my own markers they will always zoom in (or zoom out) to the default marker size and shadow size'''. In my special case I like to use really small icons for the marker, just a few pixels, without shadow. Where do I change this for the marker icons in the script? --[[User:Wikisteph|Wikisteph]] 10:37, 7 December 2006 (UTC)

Hi,
could someone make this a little bit more detailed for me?
So I have to change the section from line 426 in GoogleMaps.php ?
//<![CDATA[

and uncomment the line with CDATA ?
nothing changes for me if I change GSize, GPoint...

:--[[User:Emiller|Emiller]] 03:20, 27 February 2007 (UTC)
Thank you for your answer!
It worked for marker.png and firefox but not for IE. No more markers with IE.
I had to change:
function googleMaps_GetDefaults() 
and change the default "icon" => 
to s.th. i want to use.
I didn't had to change anything in
$output .= " GME_DEFAULT_ICON = new GIcon(G_DEFAULT_ICON, '".addslashes($o['icon'])."');";
Together it looks like this:
<pre>
if ($o['icon'] != 'http://www.google.com/mapfiles/marker.png') {
$output .= " GME_DEFAULT_ICON = new GIcon(G_DEFAULT_ICON, '".addslashes($o['icon'])."');";
$output .= " GME_DEFAULT_ICON.iconSize = new GPoint(12, 10);";
$output .= " GME_DEFAULT_ICON.shadowSize = new GSize(22, 20);";
$output .= " GME_DEFAULT_ICON.iconAnchor = new GPoint(12, 10);";

}
</pre>
Is it possible to add even marker{label}.png.
I tried with :
<pre>
if ($o['icons'] !=...........
</pre>
, but failed.
Thank you

===Signing entries using tildes===
Question: Is there any way to sign entries using four tildes '''<nowiki>~~~~</nowiki>''' so that every member on the wiki can add a point to a map and easily add their name and date to it? Thanks - [[User:MediaHound|MediaHound]] 03:14, 3 November 2006 (UTC)

===Working with templates===
This map is working great on our [http://www.singletrackwiki.com SingletrackWiki]

Does anyone know if there is a way to make MediaWiki read template variables that are within extension code tags? such as:

<googlemap lat="{{{latitude}}}" lon="{{{longitude}}}" zoom="1" width="270" height="180" controls="small">{{{latitude}}},{{{longitude}}} {{{description}}}</googlemap>

This way, my template could be called by:

<nowiki>{{Googlemap | latitude = XX.XXXXXXX
| longitude = -XXX.XXXXXXX
| description = some landmark
}}</nowiki>

Instead of the users having to put in all of those coordinates 3 times, they could put them in once and the template would automatically insert them into a "get directions" link, and into the google map extension tags, and create the map.

Any ideas on how this could be done? I know there have been various "mods" or "patches" for mediawiki that were created, but none of those seem to work with the current version.

::You can make a template with variables, as you suggested above and use the syntax <nowiki>{{subst:googlemap|lat|lon|desc}}</nowiki>. This will produce the desired output, although it is unfortunately a one shot deal as it copies the text in the page that uses the template when it is saved. Changes to the template will therefore not be reflected on the end pages. This somewhat defeats the purpose, but can at least be used as a tool for users who don't want to mess around with the actual syntax. It still clutters the page, though. Less than ideal. --Charles

::There's an open bug in MediaWiki about this (including a patch, if you're brave): http://bugzilla.wikimedia.org/show_bug.cgi?id=2257 --[[User:Emiller|Emiller]] 01:33, 8 January 2007 (UTC)

::I'm on mediawiki 1.10.1 and i patched parser.php but it still doesn't parse the maps code if i use it in a template. On the #wikimedia channel on freenode i was adviced: "There's a hook for it in the parser. It's a different hook than the normal extension hook. Extensions have to use the new hook if they want the new behaviour. Otherwise, it might break functionality. e.g. <nowiki><math> uses {}</nowiki> itself", so apparently this could be fixed by just modifying googlemaps code and not waiting for a fix from mediawiki.

:::Now I tested it on 1.11.0, and it completely breaks the wiki after update. Needs to be disabled completely in order for the wiki to work. I'm surprised on one has yet addressed these problems.

=== Add a clickable sidebar? ===

Love the extension! I was wondering if there was any way that you could have a clickable sidebar that brings up the locations on the map and the corresponding info ballon. For example on my page [http://www.chesterwiki.com/Map Chester Wiki] I have A for attractions, B for bars and R for restaurants. Is there anyway of adding the points into empty divs named sidebar1 sidebar 2 and sidebar3?

For example...[http://www.econym.demon.co.uk/googlemaps/basic2.htm This tutorial] .

appreciate it might me a bit too much but any help would be great. Thanks

=== Installing stops MediaWiki from creating output ===

I installed the extension as per the basic three steps, but as soon as I complete the edit to LocalSettings, it completely stops the Wiki from operating (I just get an empty white page). Commenting out the two entries in LocalSettings gets the Wiki working again, what might I have done wrong?

However, have you considered letting us specify the colour of the waymarker for the entries we make?

Thanks for your excellent code.

Ohh actually. This is unlikely, but I must admit it would be nice if you have a point, which leads to a page, to be able to have a return link "map" that takes you back (that's easy) and selects/centers the map point in question (harder) ...

:Other extensions will not work inside the google map. Not sure if this is fixable, but I'll check. --[[User:Emiller|Emiller]] 09:36, 28 February 2008 (UTC)

=== Filter options ===
Filtering places by time frame, category etc. would be very interesting. Something like:
* show only objects between 1800 and 1900.
* show only objects with certain category (does not have to be the MediaWiki categories).
* show only objects of a certain area.

A format could be:
time:1800
category:castle
area:germany

The extension would collect all this information and created comboboxes, just like within the editor.

time: ( ) 1700 ( ) 1800 ( ) 1900 
category: ( ) castle ( ) palace ( ) village 
area: ( ) germany ( ) austria ( ) hungary 

Would this be hard to implement?

=== Error:addLoadEvent is not defined ===
We have been using the Google Maps Extension 0.7.4 without problems for a while. I recently upgraded to MediaWiki 1.8.2 and installed the Semantic MediaWiki extension. Now in Firefox we are getting the error "Error:AddLoadEvent is not defined. And of course no map is drawn. Here is an example page http://www.archiplanet.org/wiki/109--115_Wood_Street

[http://www.archiplanet.org/wiki/Google_maps_extension_addLoadEvent_error Here] is a page showing the wiki tags we are using, the HTML source of a broken map page and the HTML source of that page back when it worked. It looks like the first couple sets of script tags are missing including the one where it calls Google Maps. I tried putting the map code on a page that doesn't use Semantic MediaWiki and the error still occured. I tried turning off SMW and the error still occured.

I have fixed it for now by commenting out both instances of "$wgGoogleMapsDidInsertEssentialJs = true;" in GoogleMaps.php. This causes it to load the initial script stuff for every map on the page, rather than only once as is intended, but for some reason it was not loading at all for me. It seems to work with multiple instances of that code in the browsers I have tested (Safari and Firefox).

: The same is the case with SpamBlackList extension for mediawiki. Example on http://www.skipper2skipper.com. If blacklist extension is enabled, the GoogleMap javascript is not included in the page and no map is displayed. I have also disabled caching by commenting out $wgGoogleMapsDidInsertEssentialJs = true; (there are 2 instances) and all seems to be well. I guess it will need to be addressed at some stage as it does affect a few extensions, but the above fix should work in the short term. --[[User:Skipper|Skipper]] 18:05, 6 January 2007 (UTC)

===Performance issue===

Very cool extension, works for me but... with this extension installed the time it takes for the "edit" page to load jumped significantly to a few seconds. (from sub second load time) This is fine for an experiment but not for a production site, since 99.9% of page edits won't be for maps, users shouldn't have to pay this overhead in usability expense for a mapping feature.

I believe the added load time is probably due to the "fetching" of remote images and script files from google.com. A fix that would work for me is to only fetch the remote files and scripts when a user really wants to make a map (clicks on the "make a map" link). (and/or cache these images and scripts locally) Otherwise get nothing from google and spare everyone the wait. --[[User:Maxelrod|Maxelrod]] 17:58, 13 April 2007 (UTC)

:I really have to agree with Maxelrod on this - very cool extension and I'd love to use it, but the slow down on each page edit is too much especially on an active wiki. I second the idea of fetching remote files only when the button/link is clicked on. --[[User:Chrys|Chrys]] 19:17, 2 December 2007 (UTC)

</googlemap></pre>

'''Snapshot for my error code http://jwiki.biz/code.png'''

<nowiki>there are <pre> code arround my code. (I think it shouldn't have it)</nowiki>

and when I copy the code, and paste it.. it goes

<googlemap lat="35.692367" lon="139.715624" zoom="14" width="700">35.678982, '''139.71588135.683793''', 139.72420735.689649, 139.70953</googlemap>

Several code are stick together...
so, I have to make them separate by my self.

=== Problem with hooks in Xoops MediaWiki module ===

I'm running a [http://www.xoops.org Xoops CMS], with [http://www.xoops.org/modules/news/article.php?storyid=3443 MediaWiki module] in it. It's a 1.71 MediaWiki version hooked to work as a module in Xoops.
When I install this extension I get following error message on any wiki page:

Unknown datatype in hooks for ParserAfterTidy

Backtrace:

Now, I am not good neither in php nor MediaWiki, but I tried to comment from line #130 to #134 in GoogleMaps.php

if( isset( $wgHooks['ParserAfterTidy'] ) && is_array( $wgHooks['ParserAfterTidy'] ) ) {
array_unshift( $wgHooks['ParserAfterTidy'], array( $wgGoogleMaps, 'commentJS' ) );
} else {
$wgHooks['ParserAfterTidy'] = array( array( $wgGoogleMaps, 'commentJS' ) );
}

and it worked while pages were shown, but when I went to edit page, added <googlemap ...> tag, and did the preview, I got the dump of text, obiously not transformed form object to HTML...

So, do you have any idea what should go wrong? Thanks!

===Wrong shadow for custom marker icons===

::Note that, after checking [[Extension:Google_Maps/Compatibility]], I noticed that the GoogleMaps extension hasn't been listed as compatible with MediaWiki 1.9.3.

::Not sure if this counts as "Resolved." The problem is NOT with the GoogleMaps extension. It's a problem with the php.ini file on your host provider.

=== php error after installing v0.9.1 ===
I'm using mediawiki 1.6.7 and php 4.4.2-1.1 and I've been using version 0.7 of the google maps extension for some time now. Replacing the GoogleMaps folder with the new files from 0.9.1 I get on calling any mediawiki page (and just that):
: Parse error: syntax error, unexpected T_CONST, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in
: /home/www/web111/html/w/extensions/GoogleMaps/GoogleMaps.body.php on line 25

If I counted correctly the line 25 is the first line with a command:
:l.19--->class GoogleMaps {
:l.25---> const PARSE_INCLUDES = 0;

Is the php version the problem? Can I update to version .9, though my webspace provider offers this old php version?
Or might there be another problem. I did apply the "Colored paths"-changes to my mediawiki, and it worked with v.7. I hope someone might know better than I do, what this error message says.

=== New Google API Terrain update? ===

HI,

Thanks for a great extension!

Are there any plans to update this extension to support the new 'terrain' option that is in the latest API?

Google haven't enabled it by default, but it can been easily enabled it seems. See http://googlemapsapi.blogspot.com/2007/12/v294-terrain-and-new-maptypecontrol-to.html

It's probably really simple to do, and I'll have a look at the code myself tomorrow to see if I can figure it out.

Ideally, I'd like to keep the hybrid button as well, but just add the terrain button...

*I would really like to be able to load kml files, as they can contain so much more information just ready to go. It look likes the more recent GM API will also allow kml network links as well - so maps can be [http://googlemapsapi.blogspot.com/2007/10/better-kml-support-in-maps-api-dynamic.html dynamic]. I just want to specify a URL that links to the file and that file be loaded using code like so:

// get the kml File
var kmlFile = new GGeoXml("http://www.xyz/kml/my.kml", function() {
if (kmlFile.loadedCorrectly())
{
// cancel the "Loading" message
document.getElementById("loadingMsg").innerHTML = '';
}
});
map.addOverlay(kmlFile);

Better still; do it as an array of files, so mashups of multiple kml files can be shown. The loading message could be left out - otherwise the message would have to sit on the map somewhere. In the past I have used an animated gif that rotated around as the "loading msg".

Background info for readers: kml files can be made using Google Earth or Google Maps My maps. Also lots of GPS software can produce them.

Great extension ! Thank you for the hard work.
Sure, there is a lot of new functions to be added but first I have some problem with distance :
Here is a simple exemple (the whole erratic behaviour is more complicated).

A path of four points (three vectors of visualy same lenth) and two right angle.
The distance calculated for each the two first vectors is twice as long as the third.
Apparently the third one is the correct one. Is this a bug of google function ?

=== Markers don't work properly unless preceded by a space ===
Syntax says: "The line should then have the latitude, then a comma, optionally a space, then the longitude, then a comma, then a label for the point." If you put the marker text immediately after the longitude without a space (as in CSV export), then the marker shows up on the map but it isn't clickable.

Example: <code>28.607122,-80.546,Maximum dynamic pressure</code> shows the marker, but <code>28.607122,-80.546, Maximum dynamic pressure</code> puts a clickable marker on the map.

=== Call-time pass-by-reference has been deprecated ===
just started up a new install of MW 1.11 and threw the GM 0.9 extension in. i get a warning now of:

If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. in /home/''server''/''account''/''site''/extensions/GoogleMaps/SpecialGoogleMapsKML.php on line 43

"Temporary solution:
Just go ahead and remove the leading "&" sign on the parameters in the function calls at the stated lines (line 401 in GoogleMaps.body.php and line 43 in SpecialGoogleMapsKML.php)."

the fix listed above and in an above post works to get rid of errors but i don't know if it fixes the problem.
I don't want to create a custom php.ini setup to set allow_call_time_pass_reference to true, because of my host's setup.

Is GM 0.9 compatible with MW 1.11 and php 5+?

Any help would be appreciated.

=== EditorsMap.js and Mediawiki 1.10.1 ===

I recently upgraded to 1.10.1 and 0.8.0 and now the map editor no longer works. The Google Maps are rendered correctly, just the map editor no longer works.

Firebug throws me a javascript error: this.toggle_link has no properties or emap has no properties in EditorsMap.js.

== New Issues Go Here ==

=== how do I use different icon sets? ===

I have 3 / 4 different types of locations (our branches, partners, clients, highsites), and I would like to use different coloured icons for each "group", how do I do this?

=== Template:Google Maps Extension Info ===

I think this template should only be used on the main page, because it creates to many entries in the category extension. Since all subpages have a link to the toppage, I do not see any problems here. --[[User:GunterS|GunterS]] 19:19, 20 March 2007 (UTC)

=== Storing marker locations in the DB ===

I wanted to store map marker locations in the database rather than in wiki pages, and have hacked the extension to be able to fetch markers and display them--either all markers in a category, or just one marker by name. Would the diff/patch be of interest at all? [[User:Thinkling|Thinkling]] 22:36, 21 March 2007 (UTC)
:I have a site with a lot of differently centered maps, but would like to have the same markers/category of marker displayed on all maps, i think your patch may help [[User:O1ive|O1ive]] 08:32, 14 May 2007 (UTC)

:I also have markers stored in a database and want to include them into a GoogleMap. Therefore I wrote a separate extension that includes the GoogleMap-extension described here and feeds it with coordinates and descriptions from my database. Using an old version of Mediawiki and the GoogleMap-extension version 0.5.5 everything worked fine. After upgrading my Mediawiki-installation to version 1.11.1 and using the GoogleMaps extension version 0.8.0 I'm not able to get the stuff working. Here's the code of my extension:
<?
$wgExtensionFunctions[] = "mcmap";
function mcmap()
{
global $wgParser;
$wgParser->setHook( "mcmap", "renderMcmap" );
}
function renderMcmap ( $input, $argv, &$parser )
{
global $wgParser, $wgUser, $wgTitle, $wgOut;
$wgParser->disableCache();
$abfrage = "SELECT ... "; # my database query
$ergebnis = mysql_query($abfrage);
while ($data = mysql_fetch_assoc($ergebnis))
{
$myoutput .= "..."; # generation my coordinates and descriptions
}
mysql_free_result($ergebnis);

global $wgGoogleMaps;
return $wgGoogleMaps->render($myoutput, $argv, &$parser, &$parser);
}
?>

The last two lines are highly doubtful, the return command causes an UNIQ/QINU error and non of the usual solutions helped me. Any ideas?

=== Maps using Category ===

I would love to see a calendar that linked to multiple Wiki pages using the Category tag. Something like the way this calendar extension works: [[Extension:Calendar (Barrylb)]]

You would add pages with categories like this: <nowiki>[[Category:mytown|32.81134,48.498341]]</nowiki>, and then, when you put this tag in: <googlemap category=mytown lat="32.82422" lon="48.481141">, it would put in markers for each page in the category with a link to the page.

=== Parsing google map syntax to a template.. ===

Great extension... !! I have a question that i really hope you can help me out with.

I have created a custom form for users to input information into when they hit the "edit" button. So the traditional bland edit screen isnt visible. Is there anyway i can put the add a map link on this new edit page? and once then link is set it there anyway to parse this value to a text box on the custom edit page?

thanks in advance!!!

=== Safari can hang on long paths ===

I have not been able to isolate what the problem is exactly or where the limit is but I have a page with a 10-mile track with track points every 1/6th of a mile, I think. The page will load just fine on my Mac using Firefox but it causes Safari to hang indefinitely and the Finder says it is "Not Responding." This is the page causing the problem:

http://sonomavalleycyclists.org/wiki/index.php?title=Lovall_Valley&oldid=1586

I wish I could identify what it is but I can edit out the path and add it back in pieces and the pieces show. I just don't know where, yet, it decides to balk. I do know this can basically work in Safari because the following page, displays properly:

http://www.xcrides.com/index.php?title=Pian_delle_Bosse

Is it possible there is a limit to the number of points in a track that Safari can support? Could this be a weakness in the extension? Or could my data be malformed in some way?

OK, I started experimenting and found that it works up to 451 track points for this file, if I counted correctly -- I could be off by one. At 452, the previous version of the file, Safari still hangs:

http://sonomavalleycyclists.org/wiki/index.php?title=Lovall_Valley&oldid=1597

I still don't know if this is just a size issue or in some sense due to the fact that much of the second half of the track overlaps the first half.

=== "Invalid Character" in IE 7.0 ===
I just installed the Extension (on Mediawiki 1.10.0) and everything went smoothly - except the map does not appear in the page after editing. The map editor works great. I copy and paste the <googlemap> code in and hit preview (or save). The resulting page shows an IE error (yellow hazard triangle in the status bar with the text "Done, but with errors on page". If you click the status bar to show the error it shows the message "Error: Invalid character" (with line number and character number). The character referenced seems to be in the Javascript block generated by the Map extension right near where it says <pre>href="\&quot;http</pre> I notice if I take out the whole <a ... > tag (about using a compatibile web broser) save the page to my pc, then load this saved page in IE, the map comes up fine. Anyone know what this might be? The symptoms seem similar to an error referenced above (Editor works, but no visible map after preview/save) but different error messages (and causes?). Any help would be greatly appreciated. Graham [[User:70.18.28.113|70.18.28.113]] 00:33, 12 August 2007 (UTC)

=== Latitude/longitude in DMS conversion into Decimal degrees? ===

I am need of suggestions. All my points I want to use are recorded as Degrees Minutes Seconds. IS there a way of inputing this into the syntax and obtaining the correct map? Currently I need to convert all my points into Decimal degrees, point by point. Any assistance is welcomed!

:I will include this feature in a future version. --[[User:Emiller|Emiller]] 22:29, 26 February 2008 (UTC)

Have a look at this [http://www.lynedochpublications.com.au/radiosites/inc/dms2decimal.txt code]. It's based on this [http://www.movable-type.co.uk/scripts/LatLongVincenty.html Javascript]. This PHP version is my work and can be used as is - note that it is loosely based on the original Javascript. Refer to [http://www.movable-type.co.uk/scripts/LatLongVincenty.html copyright statement] on original Javascript page.

=== "helper" like gmap ===

The gmap extension has a "helper" attribute so it is easy to locate lat/lon coords. With this extension, how can I scroll around the map and find the lat/lon coords I'm interested in? Do I have to use a completely different app to find the coords and then paste them in here? [[User:128.23.114.39|128.23.114.39]] 19:24, 7 September 2007 (UTC)

=== Using the FCKeditor integration with MW 1.10.1 ===

The normal MW editor is working fine but by default my users will use the FCKeditor. This editor shows no button for this google maps extension. I would like to know how I can either add the button into the FCKeditor or make some sort of link on the edit page which is outside of the editor area. (like I guess the older version used to use?)

=== Cache problem ===

I use [[Manual:Short URL|Short URL]] for my MediaWiki installation, therefore I assigned two keys in $wgGoogleMapsKeys:
# <tt>MyIP/wiki/</tt> (short URL, for <tt>/wiki/ArticleName</tt>)
# <tt>MyIP/w/</tt> (real installed path, like <tt>/w/index.php?title=ArticleName</tt>)

Sometimes, the script said that the key is invalid in /wiki/Article which the key for [2] is used instead. I traced and tested the source and found it very weird that some variables are set differently. (For example, in <tt>GoogleMaps::commentJS()</tt>, the variable <tt>$this->mGoogleMapsOnThisPage</tt> is <tt>false</tt> in [1], but <tt>true</tt> in [2])

Finally, I resolved this problem by [http://thinkhole.org/wp/2006/09/13/disabling-caching-in-mediawiki/ disabling some cache mechanism in MediaWiki]. However, this is not a good in consideration of the server load. And after I enabled caching, the problem occured again. Is there any way to resolve this problem (and still using short URL)? Or do I need to provide more information?

=== Using this extension with the FCKeditor ===

I have to disable the FCKeditor in order to make the extension work because the "make a map" button will not show up anywhere on the edit page dialog with the FCKeditor. Can anyone help me or just give me some way of enabling this extension with the FCKeditor anyway? I'm not asking for full functionality with the FCKeditor or anything. Just a little text link above the editor window would be great! I just don't understand the complexities of the code well enough to get MW 1.10.1 to play with this extension and the FCKeditor integration at the same time!

I guess my problem really is: How can I instantiate the map editor somewhere else besides in the editor? (like maybe below or above it)

FCKeditor renders the <googlemap> tags just fine. I just need to let the user have an interface with which to edit the article since this is essential to the goal of my wiki site. (allowing each user a simple way to add a map to their article).

Thanks again!

same here, i think it must be taken up with the fckeditor people though as it is removing the buttons

-oktiv 01nov2007

-UPDATE-
someone has come up with a plug-in for FCKeditor because there is no license attached I will only link to the discussion. Please see http://www.fckeditor.net/forums/viewtopic.php?f=5&t=6627&p=17827&hilit=google+maps#p17827
It works fine on a regular website but doesn't format the tags into wiki text. I am wondering if some of the code from the wiki + googlemaps extension can be utilized inside of the FCKeditor plug-in, possibly having them both installed side by side and adding a call to the parser inside of the google maps wiki extension. I don't know enough about js to do this. I am willing to help sponsor this feature. djoktiv@gmail.com

=== KML export problem ===
Using Mediawiki 1.11.1 Installed extension ver 0.9.1 All worked a treat excpet for KML export. All polylines had the first coordinate repeated at the end of the line, so all the lines became enclosed spaces. ie somehow the first co-ord was duplicated at the end unnecessarily. Also markers are labelled as Point 1, Point 2, etc as opposed to showing the Title of the marker as seen in the Title bubble on the map.

OK thought ver 0.9.2 may contain a fix for the lines. Now clicking on a link to start a KML export this gets displayed:

Warning: SpecialPage::require_once(/home/bbug/public_html/wiki/includes/SpecialGoogleMapsKML.php) [function.SpecialPage-require-once]: failed to open stream: No such file or directory in /home/bbug/public_html/wiki/includes/SpecialPage.php on line 646

=== GM plugin - mmmmm good stuff ===
*I wanted to set the version of the Google API to 2.x, which as I understand it, always makes use of the latest GM API. However array element $o['version'] is set to a floating point number, whereas 2.x is a string. So when I set the override in LocalSettings.php I got a: "Parse error: syntax error, unexpected T_STRING". I would have thought the type casting would straightened things out but apparently not. I then tried to define $o['version'] as a string '2.85' but that didn't appear to work either. No errors but the override in LocalSettings.php didn't work. It is possible the browser's page cache might not have shown the update. Any thoughts on this?

var BUBBLE_SCALE = 0.5;
var bubble_w = map.getSize().width * BUBBLE_SCALE;

=== Map doesn't load properly in IE ===

I just upgraded to 0.8 and i realise that the markers and shading on the map don't load immediately in IE, you have to click on Map/Hybrid/Satellite for them to show up, and then if you zoom in/out again the markers disappear.

If it is set to Hybrid the streets/neighborhood overlay shows plus the above-mentioned extras but not the satellite pictures. Also the zoom function does work even with no map/sat pics, you see the zoom "guide" appear and the sliding scale moves.

== Using Dynamic Page List (DPL) to auto-generate maps ==

Hi Evan,

on http://semeb.com/dpldemo/MapDemo you can find a map which shows "points of interest". The interesting thing is that the POIs on the map come from articles within that wiki; the articles only must use a simple template to state the coordinates and a text (or an image). That´s all. DPL collects those template calls and constructs a call of your googlemaps extension on the fly. It even generates a table with the POIs below the map.

I think this could be of some interest for others as well.

When creating this little application I found two minor problems with your code (regarding the use of uninitialized hasmap elements in php5). Bruno Marcuzzo sent you an email which contains the corrected version. Please check the changes I made and adopt them.
