    中的菜单项列表

    我目前正在研究自定义主题.在这个主题中,我有一个使用register-nav-menu注册的菜单,然后使用wp_nav_menu函数将其显示在网页上.>

    但是,我只想检索菜单项列表(仅在wp-admin区域中用于创建菜单的实际菜单项名称,而没有任何html),并且我想保存该菜单项列表到一个数组(即不显示它).

    因此,伪代码看起来像这样

     $menu_items = get_list_of_items($name_of_menu); // $name_of_menu is the result of register-nav-menu, and get_list_of_items is the psuedo function
foreach ($menu_items as $item) {
    // do something with the item
}

    有办法吗?谢谢.

    wp_get_nav_menu_items 似乎正是您所需要的.它返回一个菜单对象数组.

    正如@vancoder提到的,wp_get_nav_menu_items()是必经之路,但是我认为更好的详细答案对以后的人们会有所帮助.

    所述函数返回一个WP_Post Object对象的数组(因此,您可以使用箭头访问值,例如$item->title).

    对于基本设置,您可以使用以下命令:

     $menuLocations = get_nav_menu_locations(); // Get our nav locations (set in our theme, usually functions.php)
                                           // This returns an array of menu locations ([LOCATION_NAME] = MENU_ID);

$menuID = $menuLocations['primary']; // Get the *primary* menu ID

$primaryNav = wp_get_nav_menu_items($menuID); // Get the array of wp objects, the nav items for our queried location.

    然后,您可以循环遍历$primaryNav变量,例如:

     foreach ( $primaryNav as $navItem ) {

    echo '<li><a href="'.$navItem->url.'" title="'.$navItem->title.'">'.$navItem->title.'</a></li>';

}
    • 对我来说这返回"假"
    • 您是否在复制粘贴@JohnSmith?您需要使用_your_菜单的ID.
    • 我发现这比使用walker类要容易得多.好一个！

    获取简单的菜单数组.

    添加到Functions.php 

         function wp_get_menu_array($current_menu) {

    $array_menu = wp_get_nav_menu_items($current_menu);
    $menu = array();
    foreach ($array_menu as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID'] = $m->ID;
            $menu[$m->ID]['title'] = $m->title;
            $menu[$m->ID]['url'] = $m->url;
            $menu[$m->ID]['children'] = array();
        }
    }
    $submenu = array();
    foreach ($array_menu as $m) {
        if ($m->menu_item_parent) {
            $submenu[$m->ID] = array();
            $submenu[$m->ID]['ID'] = $m->ID;
            $submenu[$m->ID]['title'] = $m->title;
            $submenu[$m->ID]['url'] = $m->url;
            $menu[$m->menu_item_parent]['children'][$m->ID] = $submenu[$m->ID];
        }
    }
    return $menu;
}

    转到标题和呼叫功能 

     <?php
 $a = wp_get_menu_array('top-menu-header');                         
 print_r($a); exit;                       

?>

    具有递归循环的上述的修改版本.

    添加到Functions.php 

     function wp_get_menu_array($current_menu='Main Menu') {

    $menu_array = wp_get_nav_menu_items($current_menu);

    $menu = array();

    function populate_children($menu_array, $menu_item)
    {
        $children = array();
        if (!empty($menu_array)){
            foreach ($menu_array as $k=>$m) {
                if ($m->menu_item_parent == $menu_item->ID) {
                    $children[$m->ID] = array();
                    $children[$m->ID]['ID'] = $m->ID;
                    $children[$m->ID]['title'] = $m->title;
                    $children[$m->ID]['url'] = $m->url;
                    unset($menu_array[$k]);
                    $children[$m->ID]['children'] = populate_children($menu_array, $m);
                }
            }
        };
        return $children;
    }

    foreach ($menu_array as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID'] = $m->ID;
            $menu[$m->ID]['title'] = $m->title;
            $menu[$m->ID]['url'] = $m->url;
            $menu[$m->ID]['children'] = populate_children($menu_array, $m);
        }
    }

    return $menu;

}
