如何在drupal中获取某个父项下的所有菜单项? [英] how to get all the menu items below a certain parent in drupal?

问题描述

我真的只需要某个菜单项下第一级的 mlid 和标题文本.这就是我目前正在做的事情.(它有效，但我怀疑可能有更像 drupal 的方式.):

I really only need the mlid and title text for the first level below a certain menu item. Here's what I'm doing at the moment. (It works, but I suspect there may be a more drupal-y way.):

/**
 * Get all the children menu items below 'Style Guide' and put them in this format:
 * $menu_items[mlid] = 'menu-title'
 * @return array
 */
function mymod_get_menu_items() {
    $tree = menu_tree_all_data('primary-links');
    $branches = $tree['49952 Parent Item 579']['below']; // had to dig for that ugly key
    $menu_items = array();
    foreach ($branches as $menu_item) {
        $menu_items[$menu_item['link']['mlid']] = $menu_item['link']['title'];
    }
    return $menu_items;
}

有吗?

推荐答案

afaik，没有(我希望我错了).暂时，您可以通过简单地添加一个 foreach ($tree) 将您的函数变成一个更抽象的辅助函数，而不是挖掘丑陋的键.然后你可以使用你自己的逻辑来输出你想要的东西(在这种情况下是 mlid).这是我的建议:

afaik, there isn't (i hope i am wrong). for the while, instead of digging for ugly keys, you can turn your function into a more abstract helper function by simply adding a foreach ($tree). then you can use your own logic to output what you want (mlid, in this case). here is my suggestion:

/**
 * Get the children of a menu item in a given menu.
 *
 * @param string $title
 *   The title of the parent menu item.
 * @param string $menu
 *   The internal menu name.
 * 
 * @return array
 *   The children of the given parent. 
 */
function MY_MODULE_submenu_tree_all_data($title, $menu = 'primary-links') {
  $tree = menu_tree_all_data($menu);
  foreach ($tree as $branch) {
    if ($branch['link']['title'] == $title) {
      return $branch['below'];
    }
  }
  return array();
}
