What can this extension do?
This extension adds a parser function that is similar to the {{#ifexist:...}} function from extension:ParserFunctions. It works as follows {{#incat:Some category|what to do if current page is in category|what to do if current page is not in category}}. It also suports #incategory, #ifpageincat and #ifpageincategoy.
Warning: This extension doesn't work properly during preview. Once the page is saved everything works fine, but before page save, it will use whatever categories were in the article on the previous revision
Download instructions
Installation
Download thingy, put it in appropriate place in extensions directory, add line require_once( "$IP/extensions/PageInCat/PageInCat.php" ); to bottom of LocalSettings.php
Note, this will probably work for MediaWiki versions before 1.19 (provided its not super ancient), eventhough the download link only has a version for MediaWiki 1.19. If in doubt, try it out and see if it works with your version.
Configuration parameters
This extension doesn't have any configuration parameters. However, the number of times you can use #incat on a page is limited by $wgExpensiveParserFunctionLimit (defaults to 100, which should be fine for most folks). Calling #incat twice on the same page for the same category only counts once towards the expensive function limit.

- Extension:ParserFunctions
- Extension:CategoryTests (Didn't know this extension existed when I wrote this one. The main difference seems to be that PageInCat sets the page to vary by revision so that it should still work properly if both the #incat test and the category being tested were added to the page in the same revision)
