The following code will work, but you just have to keep in mind that conflicts can happen easily if the slug for your custom post type is the same as a page or post's slug...
First, we will remove the slug from the permalink:
function archi_remove_slug( $post_link, $post, $leavename ) { if ( 'service' != $post->post_type || 'publish' != $post->post_status ) { return $post_link; } $post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link ); return $post_link; } add_filter( 'post_type_link', 'archi_remove_slug', 10, 3 );
Just removing the slug isn't enough. Right now, you'll get a 404 page because WordPress only expects posts and pages to behave this way. You'll also need to add the following:
function archi_parse_request( $query ) { if ( ! $query->is_main_query() || 2 != count( $query->query ) || ! isset( $query->query['page'] ) ) { return; } if ( ! empty( $query->query['name'] ) ) { $query->set( 'post_type', array( 'post', 'service', 'page' ) ); } } add_action( 'pre_get_posts', 'archi_parse_request' );
Just change "service" to your custom post type and you're good to go. You may need to refresh your permalinks.
