How to get current page menu item ancestor name wordpress - php

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) {
$breadcrumbs[] = "{$menu_item->title}";
}
}
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>";
}

You can user this
$pagename = get_query_var('pagename');
if ( !$pagename && $id > 0 ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = $wp_query->get_queried_object();
$pagename = $post->post_name;
}

There are plenty of tutorials and code snippets online describing how to show the active page’s children (or if on one of those children, the active page’s siblings) as a sub-menu in WordPress. Usually something like this:
<?php
$ref_post = empty($post->post_parent) ? $post->ID : $post->post_parent;
$children = wp_list_pages('title_li=&child_of='.$ref_post.'&echo=0');
if ($children) {
echo "<ul>$children</ul>";
}
?>
