wordpress - Wordpress 中“wp_query”对象的 for 循环

Question

我需要检查下一个对象的任何子项本身是否有子项。我想用 for 循环来做，但我不知道该怎么做。

对象如下：

$children = new WP_Query(array('post_type'=>'page', 'post_parent'=>get_the_ID(), 'post_status'=>'publish','orderby'=>'menu_order','order'=>'ASC')); 

先感谢您 ：）

这是我的做法：

$children = get_posts( 
    array(
        'post_type'=>'page', 
        'post_parent'=> get_the_ID(), 
        'post_status'=>'publish',
        'orderby'=>'menu_order',
        'order'=>'ASC'
    )
); 

foreach ( $children as $child ) {

    $has_kids = wp_list_pages( 'echo=0&child_of=' . $child->ID );

    if ($has_kids) {
        echo $child->post_title . " has children.";
    } else {
        echo $child->post_title . " doesn't have children.";
    }

}
