How do I remove a taxonomy from Wordpress?

Question

I'm creating different custom post types and taxonomies and I want to remove the 'Post Tags' taxonomy from the default 'Posts' post type. How do I go about doing this?

Thanks.

Answer 1

I suggest you don't mess with the actual global. Its safer to simply deregister the taxonomy from the post type: register_taxonomy is used for both creation and modification.

function ev_unregister_taxonomy(){     register_taxonomy('post_tag', array()); } add_action('init', 'ev_unregister_taxonomy'); 

To remove the sidebar menu entry:

// Remove menu function remove_menus(){     remove_menu_page('edit-tags.php?taxonomy=post_tag'); // Post tags }  add_action( 'admin_menu', 'remove_menus' ); 

Answer 2

Perhaps a more technically correct method would be to use unregister_taxonomy_for_object_type

add_action( 'init', 'unregister_tags' );  function unregister_tags() {     unregister_taxonomy_for_object_type( 'post_tag', 'post' ); }
