Change labels in admin section

  • Hi, how can I change labels in the admin section. For example, instead of “Add a Post” I want it to say “Add an event”. I can do this by changing a file in the wp-admin folder, but I’d rather do this in functions.php so I don’t screw anything up if I upgrade.
    Actually, I have a lot of customizing to do in the back end. Are there any guidelines/tutorials available? Thanks!

  • Well, I’ve managed to do this by re-registering ‘Post’ type with custom labels with an init hook. Like this:

    add_action('init','test_custom_post');
function test_custom_post()
{
	$labels = array(
    'name' => _x('Books', 'post type general name'),
    'singular_name' => _x('Book', 'post type singular name'),
    'add_new' => _x('Add New', 'book'),
    'add_new_item' => __('Add New Book'),
    'edit_item' => __('Edit Book'),
    'new_item' => __('New Book'),
    'view_item' => __('View Book'),
    'search_items' => __('Search Books'),
    'not_found' =>  __('No books found'),
    'not_found_in_trash' => __('No books found in Trash'),
    'parent_item_colon' => ''
  );

register_post_type( 'post', array(
			'labels' => $labels,
           'public'  => true,
          '_builtin' => true,
          '_edit_link' => 'post.php?post=%d',
           'capability_type' => 'post',
            'hierarchical' => false,
           'rewrite' => false,
            'query_var' => false,
           'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'trackbacks', 'custom-fields', 'comments', 'revisions' ),
       ) );
}

    To change the admin tab menu labels you have to hackishly hook to a filter in the wp-admin/post.php file:

    add_filter('menu_order','change_label');
function change_label($stuff)
{
	global $menu,$submenu;

	$menu[5][0]= 'Books';
	$submenu['edit.php'][5][0]  = 'Books';
return $stuff;
}

    I wouldn’t count on it though, as the register_post_type function comment for ‘_builtin’ argument clearly says ‘THIS IS FOR INTERNAL USE ONLY!’, although after a quick glance on the code looks like it just overwrites the default defined post type – at least on WP 3.0.

    Uh, missed something. In order for above code to work, you also have to add filter for a ‘custom_menu_order’:

    add_filter('custom_menu_order','order');
function order()
{
	return true;
}
