Created Custom Post type called members, don't need a members permalink, but need to link to member patents, if exists for member (which I got figured out).

The problem I'm facing is the creation of the ep_mask and rewrites for the endpoint here.

Basically, I create a member named, "John Doe", now want the url to be something like this for showing his patents:


but I have something like this now: member/john-doe/?patents

How do I get rid of the ? mark in the url?

register_post_type('team_member', array(
        'description'           => __('Team Members'),
        'label'                 => __('team_members'),
        'labels'                => array(
            'name'                  => _x('Team Member', 'Post Type General Name'),
            'singular_name'         => _x('Team Member', 'Post Type Singular Name'),
            'menu_name'             => __('Team Members'),
            'parent_item_colon'     => __('Parent Team Member'),
            'all_items'             => __('All Team Members'),
            'view_item'             => __('View Team Member'),
            'add_new_item'          => __('Add New Team Member'),
            'add_new'               => __('Add New'),
            'edit_item'             => __('Edit Team Member'),
            'update_item'           => __('Update Team Member'),
            'search_items'          => __('Search Team Members'),
            'not_found'             => __('Not Found'),
            'not_found_in_trash'    => __('Not Found in Trash')
        'taxonomies'            => array('department', 'team'),
        'supports'              => array('title', 'editor', 'thumbnail'),
        'rewrite'               => array('slug' => 'member', 'ep_mask' => 'patents'),
        'hierarchical'          => false,
        'public'                => false,
        'show_ui'               => true,
        'show_in_menu'          => true,
        'show_in_nav_menus'     => false,
        'show_in_admin_bar'     => true,
        'query_var'             => true,
        'menu_position'         => 5,
        'can_export'            => true,
        'has_archive'           => false,
        'exclude_from_search'   => false,
        'publicly_queryable'    => true,
        'capability_type'       => 'page'

add_filter( 'request', 'filter_request' );
function filter_request($vars)
        $vars['patents'] = true;

    return $vars;

add_action( 'template_redirect', 'catch_vars' );
function catch_vars()
    global $wp_query;

    if (!isset($wp_query->query_vars['patents']) || !is_singular())

    // Template here for Member Specific Patents!
    include_once(dirname(__FILE__) . '/single-team_member-patents.php');

How to make the endpoint a folder structure instead of a ? at end with query string?


I am using this within the init action also:

function do_stuff() {
    add_rewrite_endpoint('patents', EP_PERMALINK);
add_action('init', 'do_stuff');
  • patents isn't a valid value for ep_mask, endpoint masks are defined in the rewrite API and listed on the add_rewrite_endpoint codex page. – Milo Feb 17 '16 at 18:36
  • How do you add another sub-level url, in this case /patents/ for a custom post type? I need it to be made available on all posts for that custom post type is this possible? So will be in the format: /members/{post-slug}/patents/ – Solomon Closson Feb 17 '16 at 18:46

    use add_rewrite_endpoint to add an endpoint. – Milo Feb 17 '16 at 18:48
  • Ok, sorry, forgot to mention that I am already using that function within the init action, it is not working like a directory structure, instead it is only displaying the include when I browse to: /members/john-doe/?patents, but I need it to load on: /members/john-doe/patents/, how? – Solomon Closson Feb 17 '16 at 18:52

    If you only need it for the one type, then you can use add_rewrite_rule instead. The endpoint mask determines what link types the endpoint rules are added to, a non-hierarchical singular permalink isn't further differentiated. – Milo Feb 17 '16 at 19:21

Ok, I got it, thanks for the point in the right direction guys!

add_rewrite_rule('^members/([^/]*)/([^/]*)/?', '^members/$matches[1]/?$matches[2]', 'top');
