WordPress: Disable “Add New” on Custom Post Type

Question

Is there any way to disable the option of adding a new post under a Custom Post Type in WordPress (3.0)? I\'ve looked into labels and arguments but can\'t find anything that

Answer 1

There is a meta capability create_posts that is documented here and is used by WordPress to check before inserting the various 'Add New' buttons and links. In your custom post type declaration, add capabilities (not to be confused with cap) and then set it to false as below.

register_post_type( 'custom_post_type_name', array(
  'capability_type' => 'post',
  'capabilities' => array(
    'create_posts' => false, // Removes support for the "Add New" function ( use 'do_not_allow' instead of false for multisite set ups )
  ),
  'map_meta_cap' => true, // Set to `false`, if users are not allowed to edit/delete existing posts
));

You'll probably want to set map_meta_cap to true as well. Without it, you won't be able to access the posts' editing pages anymore.
