Site-wide Categories

If you're not a programmer, don't worry! All the main Elgg tools are already adapted to use categories, and a growing number of third party Elgg tools use it too.

This plugin uses views and events hooks to allow you to easily add site-wide categories across Elgg tools.

This is a two-line addition to any plugin.

In your edit/create form:

echo elgg_view('input/categories', $vars);

In your object view:

echo elgg_view('output/categories', $vars);

Note that in both cases, $vars['entity'] MUST be populated with the entity the categories apply to, if it exists.
