The HideCategorizedOrphans extension makes MediaWiki consider pages that belong to a category not be orphans. This is useful if you want to link to a category off of a page, but the links to that individual page show up nowhere else.


  • Copy the code into files and place the file(s) in a directory called HideCategorizedOrphans in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    require_once "$IP/extensions/HideCategorizedOrphans/HideCategorizedOrphans.php";
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
