What can this extension do?
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.
To install this extension, do the following:
- add the following to LocalSettings.php:
- Run the update.php maintenance script
- 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)
Use this wiki mark-up code on the wiki page to view the results.
Some example wiki pages that use this extension include: (Feel free to insert your wiki page.)
