Unregisters a post type and removes the menu item
* Usage for a custom post type named 'movies':
* unregister_post_type( 'movies' );
* Usage for the built in 'post' post type:
* unregister_post_type( 'post', 'edit.php' );
function unregister_post_type( $post_type, $slug = '' ){
global $wp_post_types;
if ( isset( $wp_post_types[ $post_type ] ) ) {
unset( $wp_post_types[ $post_type ] );
$slug = ( !$slug ) ? 'edit.php?post_type=' . $post_type : $slug;
remove_menu_page( $slug );

Was trying to get this to work, found virtually the same code following the answer here:

I needed to use this in a Child Theme to unregister a Custom Post Type (not the slug) registered from a paid theme's plugin. I ended up removing the parameter from the function, setting $post_type inside the function equal to the name of the post type and then using the 'init' action. Couldn't get it to work without the action (could be b/c of the theme & the post type coming via plugin I suppose) so I have:

if ( ! function_exists( 'unregister_post_type' ) ) :
function unregister_post_type() {
    global $wp_post_types;
    if ( isset( $wp_post_types[ 'post_type_name' ] ) ) {
        unset( $wp_post_types[ 'post_type_name' ] );
        return true;
    return false;

add_action('init', 'unregister_post_type');

Thanks for the provided code!


It did not work for me until gave it the priority '100':

add_action('init', 'unregister_post_type',100);

Priority of '11' worked for me (WordPress default is '10').


Where exactly do you place this code? in functions.php? and then when the custom post types are deregistered does it have to stay in there?


@fgilio good find, just note that the function can't be used to remove default post types.
