The CategoryTests extension provides a set of dynamic parser functions that check for categories.
Usage
editThis currently defines 3 parser functions for category testing.
{{#ifcategory:category|then|else|page}}
- Tests if the given page is in the category given, then displays "then" or "else" (or current page if no page is given).
{{#ifnocategories:then|else|page}}
- Tests if the given page does not belong in any categories, then displays "then" or "else" (or current page if no page is given).
{{#switchcategory:category1=result1|category2=result2|...|default}}
- Operates like the ParserFunctions
#switch
, but doesn't take an initial parameter (it just starts cycling through right away) and tests if the page is in those categories instead of comparing it to a value. You can specify to test other pages using#page=pagename
, where it would then test that page instead of the current page until the next#page
definition, in which case it will test that page now instead. Making#page
empty resets it to the current page. If your default case needs an equals sign, you may use#default
to declare it.
Installation
edit- Download and move the extracted
CategoryTests
folder to yourextensions/
directory.
Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/CategoryTests - Add the following code at the bottom of your LocalSettings.php file:
wfLoadExtension( 'CategoryTests' );
- Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

edit- ParserFunctions - For more general conditional constructs
- PageInCat - The main difference seems to be that PageInCat will always try to use categories from the current revision, while CategoryTests may sometimes use the categories from the previous revision, which could result in unexpected page content
