What can this extension do?[edit | edit source]

This template creates a special page - Special:CategoryIntersection. You put in a list of categories to this page (separated by newlines), and the extension returns the articles that are in all the categories listed. It stores hashes of what categories a page is in in a separate table in db to (I assume) make things efficient. Somewhat akin to the DynamicPageList extensions (but probably much more efficient).

Note this extension might not handle a single page being in a large number of categories very well.

Installation[edit | edit source]

To install this extension, do the following:

  1. add the following to LocalSettings.php:
    require_once("$IP/extensions/CategoryIntersection/CategoryIntersection.php");
    
  2. Run the update.php maintenance script
  3. Run the refreshLinks.php maintenance script (Warning: This may take a long time if you have a lot of pages on your wiki. If you don't do this step, the extension will only find pages that had their categories added after the extension was installed)
