如何获得wp_get_nav_menu_items与父母分组子项目（） _wp_get_nav_menu

【如何获得wp_get_nav_menu_items与父母分组子项目（）】它返回一个对象, 该对象具有给定菜单的所有菜单项, 包括子菜单项, 其排列顺序在仪表板上。它不会将子菜单项与其父项归为一组, 这会使创建自己的菜单有些困难。有没有一种方法可以安排对象, 以便子项在其父项的数组内分组？
#1要解决你的问题, 你可以更改以下两行：

foreach ($item as $key => $child) if ($child-> menu_item_parent == $item-> post_name) {

带有：

foreach ($child_items as $key => $child) if ($child-> menu_item_parent == $item-> object_id) {

// wordpress does not group child menu items with parent menu items $menuLocations = get_nav_menu_locations(); $navbar_items = wp_get_nav_menu_items($menuLocations['Navbar']); $child_items = []; // pull all child menu items into separate object foreach ($navbar_items as $key => $item) { if ($item-> menu_item_parent) { array_push($child_items, $item); unset($navbar_items[$key]); } }// push child items into their parent item in the original object foreach ($navbar_items as $item) { foreach ($child_items as $key => $child) { if ($child-> menu_item_parent == $item-> post_name) { if (!$item-> child_items) { $item-> child_items = []; }array_push($item-> child_items, $child); unset($child_items[$key]); } } }// return navbar object where child items are grouped with parents return $navbar_items;
