WordPress > Custom Category Listing by excluding Category Slug matches

Question

I have a group of categories where the slug of each has a prefix "mycat-" and I would like to insert code into my sidebar.php file to create a custom sidebar widget that lists all categories except those preceeded by "mycat-".

Any help much appreciated.

Example Categories (by slug)...

mycat-hidden, mycat-favorites, mycat-nofollow, mycat-noindex, favorites, recently-updated, hot-links, etc

Given the above categories, I'd want the listing to be:

• Favorites
• Recently Updated
• Hot Links

Answer 1

You want to use this function.

wp_list_categories('exclude_tree=ID_OF_MYCAT');

Just insert your mycat parent category in there.

If you haven't set up your categories in a tree structure then you should consider doing so!
