php - 如何从 WP_Post 对象获取标题

Question

我试图查看子页面名称列表以及一些要显示的描述..我使用下面的代码

$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));
// Get the page as an Object
$portfolio =  get_page_by_title('service');
// Filter through all pages and find Portfolio's children
$portfolio_children = get_page_children( $portfolio->ID, $all_wp_pages );
// echo what we get back from WP to the browser
echo "<pre>";print_r(
);

foreach($portfolio_children as $pagedet):

        echo $pagedet['post_title'];


 endforeach;

我在使用 foreach 之前获取数组

when i print  $portfolio_children iam getting out put like this 
 Array
(
 [0] => WP_Post Object
    (
        [ID] => 201  
         [post_title] => Website Hosting
     )
  [1]=> WP_Post Object

      (
              [ID] => 202  
         [post_title] => Website
      )

在 foreach 之后如果我打印 $pagedet iam getting

WP_Post Object
    (
        [ID] => 201  
       [post_title] => Website Hosting
     )

我试着调用 $pagedet['post_title'] 但 id 没有显示任何东西...提前致谢

为了确定，您应该使用每个页面数据作为列名。

例如，

$page_data->post_content //is true,
$page_data->the_title // is false.
