Is it possible to check in WP if the current page/menu item is a child or a parent with child (in my wp_nav_menu)? So not if the page has a child page, but if the menu item is a parent with child or a child (based on my wp_nav_menu).

  • It is a bit unclear what you are trying to achieve. You should specify you question and add relevant information. Jan 16, 2015 at 14:34
  • Well, when Im on a page, i want to check whether the page is a child or a parent (with a child), based on the defined wp_nav_menu in WP admin. Hope that is clear.

    You know about the nav menu css classes? Otherwise you likely have to deal with Walker_Nav_Menu in one or another way. Jan 16, 2015 at 14:36

I agree with ialocin, if you can use the built-in nav menu css classes you should but if those aren't enough there's a nice little filter which can help with css classes. If you need something other than CSS classes you can use a Custom Walker ( as ialocin suggested ) and use the same logic as the function below.

Add some CSS Classes to WP Nav Menu

/** Custom `wp_nav_menu()` Classes **/
function add_class_to_wp_nav_menu( $classes, $item ) {

    if( hasChildren( $item->object_id ) ) {                     // hasChildren is a Custom Function
        array_push( $classes, 'has-children' );

    if( 0 !== wp_get_post_parent_id( $item->object_id ) ) {     // 0 means there is no parent
        array_push( $classes, 'has-parent' );

    return $classes;
add_filter( 'nav_menu_css_class', 'add_class_to_wp_nav_menu', 10, 2 );

/** Check if Page has Children **/
function has_children( $pid ) {
    $children = get_pages( "child_of={$pid}" );
    return ( $children );

    Correct answer, I guess - but isn't this just duplicating existing classes, e.g. menu-item-has-children or current-menu-parent? So you could just use them. @RobbertT Jan 16, 2015 at 15:00
  • @ialocin ha, yeah I guess you're right. Default classes are pretty informative.
