在我的网站上，我需要一个导航菜单来显示我的帖子安排。因此，我需要导航菜单来计算项目数量，并将每个项目的编号显示为该项目标题之前的标签。我想我们需要一个foreach 在里面wp_get_nav_menu_items 数一数，但我不知道确切的方向<我需要从菜单中找到这样的东西：
1-标题一
2-标题二
3-标题三
4-。。。
我有以下代码，但我有两个问题：
1-我不知道为什么它不工作
2-我需要一门课程.current-menu-item 在其他项目中查找当前项目。这个类是WordPress菜单中的默认类，但我不能这样做。
// Get the nav menu based on $menu_name (same as \'theme_location\' or \'menu\' arg to wp_nav_menu)
// This code based on wp_nav_menu\'s code to get Menu ID from menu slug
$menu_name = \'custom_menu_slug\';
if ( ( $locations = get_nav_menu_locations() ) && isset( $locations[ $menu_name ] ) ) {
$menu = wp_get_nav_menu_object( $locations[ $menu_name ] );
$menu_items = wp_get_nav_menu_items($menu->term_id);
$menu_list = \'<ul id="menu-\' . $menu_name . \'">\';
menu_count = 0;
foreach ( (array) $menu_items as $key => $menu_item ) {
$title = $menu_item->title;
$url = $menu_item->url;
$menu_count++;
$menu_list .= \'<li><span>\'.$menu_count.\'</span><a href="\' . $url . \'">\' . $title . \'</a></li>\';
}
$menu_list .= \'</ul>\';
} else {
$menu_list = \'<ul><li>Menu "\' . $menu_name . \'" not defined.</li></ul>\';
}
// $menu_list now ready to output
非常感谢你的帮助

感谢大家，我自己找到了：
这个测试菜单支持子菜单，子菜单将有箭头。此外，当前页面父项和菜单项将具有活动类。你很好：）
