Check usage and version matrix.

The HeaderCount extension adds a simple parser function for obtaining the number of headers, or sections, in a page.

The extension is invoked with the {{#headcount:...}} parser function.


  • Download and place the file(s) in a directory called HeaderCount in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'HeaderCount' );
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.24 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 1.24 and earlier), instead of wfLoadExtension( 'HeaderCount' );, you need to use:

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


Using this extension is fairly straight forward. The #headcount function has 2 parameters: page, and level.

When the first parameter is omitted ({{#headcount:}}), it will use the current page.

When the second parameter is omitted ({{#headcount:Page}}), it will use 2, as in level 2 headers.
