The MediaFunctions extension adds several parser functions to MediaWiki which provide access to properties and metadata of various media files in both local and remote repositories.


  • Download and move the extracted MediaFunctions folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/MediaFunctions
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'MediaFunctions' );
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.35 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.35 and earlier), instead of wfLoadExtension( 'MediaFunctions' );, you need to use:

require_once "$IP/extensions/MediaFunctions/MediaFunctions.php";
