这是我的代码,
$menu_name = 'featured-page'; // Name of Custom Navagation in the back end
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);
}
foreach ( $menu_items as $menu_item ) {
$numbers[] = get_post_meta( $menu_item->ID, '_menu_item_object_id', true );
}
var_dump($numbers) ;
var_dump($numbers) ;
会显示这个
数组(3) { [0]=> 字符串(2) "11" [1]=> 字符串(1) "9" [2]=> 字符串(1) "8" }
我需要打印出来
11,9,8
如何才能做到这一点?
