Wordpress - Remove Categories / Tags From Admin Menu
add_action('admin_menu', 'my_remove_sub_menus');
function my_remove_sub_menus() {
remove_submenu_page('edit.php', 'edit-tags.php?taxonomy=category');
remove_submenu_page('edit.php', 'edit-tags.php?taxonomy=post_tag');
}
If you want to completely remove categories and tags you can do so like this:
// Remove Categories and Tags
add_action('init', 'myprefix_remove_tax');
function myprefix_remove_tax() {
register_taxonomy('category', array());
register_taxonomy('post_tag', array());
}
You may also want to remove the meta boxes from the Post Creation page
// REMOVE POST META BOXES
function remove_my_post_metaboxes() {
remove_meta_box( 'categorydiv','post','normal' ); // Categories Metabox
remove_meta_box( 'tagsdiv-post_tag','post','normal' ); // Tags Metabox
}
add_action('admin_menu','remove_my_post_metaboxes');
