What can this extension do?Edit

This extension warns user if she did not specify any category when editing a page. It does not block user from saving the uncategorized page, though.


Just download and install and select namespaces for displaying warnings.

Download instructionsEdit

Clone a git repository from [1], extension is in extensions/WarnNoCategories directory.

Copy this directory to your $IP/extensions/. Note: $IP stands for the root directory of your MediaWiki installation, the same directory that holds LocalSettings.php.

Simpler instructionsEdit

Go to this specific page and, on the two raw links, right-click and select download. You will need to name the files WarnNoCategories.i18n.php and WarnNoCategories.php


To install this extension, add the following to LocalSettings.php:


Configuration parametersEdit

This extension has single parameter: $wgWarnNoCategoriesOnNamespace - set (array) of namespaces for which warnings are enabled. By default it is empty.

To enable warnings on some namespace, add the namespace to array. For example, enabling warnings in main namespace:

$wgWarnNoCategoriesOnNamespace[NS_MAIN] = true;

This line is to be added to LocalSettings.php, after extension including directive.
