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

The combinations of the solutions above work in hiding the links (although someone could quite easily type the URL in directly.

The solution mentioned @3pepe3 relies on get_post_type() which will only work if there is already a post in the listing. If there are no posts, the function will not return anything, and the "Add New" link will be available. An alternative method:

function disable_new_posts() {
    // Hide sidebar link
    global $submenu;
    unset($submenu['edit.php?post_type=CUSTOM_POST_TYPE'][10]);

    // Hide link on listing page
    if (isset($_GET['post_type']) && $_GET['post_type'] == 'CUSTOM_POST_TYPE') {
        echo '';
    }
}
add_action('admin_menu', 'disable_new_posts');

EDIT: To prevent direct access if someone types the URL in themselves: https://wordpress.stackexchange.com/a/58292/6003
