问题描述：

I would like to know how to retrieve as variable the name of the current page.

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

我想知道如何检索当前页面的名称作为变量。

例如，我的菜单如下：</ p>

  Item 1 
Item 2 =＆gt; 子项目1 
</ code> </ pre> 
项目1＆amp;  2是自定义链接。  sub-item1是我的页面。</ p> 
当我在这个页面上时，我想要检索“Item 2”名称（以构建我的自定义breadcumbs）</ p> 
谢谢</ p> 
</ div> 
网友观点：
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 = \' &gt; \') {
$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>\\\";
}

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>\\\";
}
?>
