如何获取当前页面菜单项祖先名称wordpress

Question

I would like to know how to retrieve as variable the name of the current page. For exemple, My menu is like :

Item 1
Item 2 => sub-item 1

Item 1 & 2 are custom links. sub-item1 is my page.

When I'm on this page, I want to retrieve "Item 2" name (to build my custom breadcumbs)

Thanks

BREADCRUMBS:

Here is a breadcrumbs function that work with the hierarchy of your menu. Add this to your theme's 'functions.php'.

function my_menu_breadcrumb($theme_location, $separator = ' > ') {
    $locations = get_nav_menu_locations();
    if ( isset( $locations[ $theme_location ] ) ) {
        $menu = wp_get_nav_menu_object( $locations[ $theme_location ] );
        $menu_items = wp_get_nav_menu_items($menu->term_id);
        _wp_menu_item_classes_by_context( $menu_items );
        $breadcrumbs = array();

        foreach ( $menu_items as $menu_item ) {         
            if ($menu_item->current) {
                $breadcrumbs[] = "<span title=\"{$menu_item->title}\">{$menu_item->title}</span>";
            }
            else if ($menu_item->current_item_ancestor) {
                $breadcrumbs[] = "<a href=\"{$menu_item->url}\" title=\"{$menu_item->title}\">{$menu_item->title}</a>";
            }
        }

        echo implode($separator, $breadcrumbs);
     }
}

You can then call as <?php my_menu_breadcrumb('header-menu'); ?> where 'header-menu' is the menu location name. In the loop, $menu_item->title will return page title and $menu_item->url it's URL.

PARENT MENU TITLE:

Here is the function to get parent menu item title(s) of current page - add this to your theme's 'functions.php'.

function my_menu_parent($theme_location) {
    $locations = get_nav_menu_locations();
    if ( isset( $locations[ $theme_location ] ) ) {
        $menu = wp_get_nav_menu_object( $locations[ $theme_location ] );
        $menu_items = wp_get_nav_menu_items($menu->term_id);
        _wp_menu_item_classes_by_context( $menu_items );
        $breadcrumbs = array();

        foreach ( $menu_items as $menu_item ) {         
            if ($menu_item->current_item_ancestor) {
                $breadcrumbs[] = $menu_item->title;
            }
        }

        return $breadcrumbs;
     }
}

You can then call as below where 'header-menu' is the menu location name.

$parentitems = my_menu_parent( 'header-menu' );
foreach ( $parentitems as $parentitem ) {
    echo $parentitem."<br>";
}
