It is possible to block a user on editing base on custom status

Hello,

There are a few example on the web about how to prevent editing a post while the post meets certain conditions. Adding the following snippet to your functions.php file would prevent posts from being edited by non-admins when the post has the status “pitch”.

function restrict_editing_by_status( $allcaps, $cap, $args ) {

    if( 'edit_post' != $args[0] && 'delete_post' != $args[0]
      || !empty( $allcaps['manage_options'] ) // don't restrict if the user can manage options
	  || empty( $allcaps['edit_posts'] ) // the user already can't edit post
	) { 
		return $allcaps;
	}
 
	$post = get_post( $args[2] );
	
	// If the post status is pitch
	if ( $post->post_status === 'pitch' ) {
		$allcaps[$cap[0]] = false;
	}
 
    return $allcaps;
}

add_filter( 'user_has_cap', 'restrict_editing_by_status', 10, 3 );

Thanks!
