我正在构建以下脚本，以从某个页面的每个子页面查询数据。我有它工作正常，但我无法获得特色图像，因为我正在使用$post->ID. 我会改变什么$post->ID 为了正确使用我的其他功能？任何帮助都将不胜感激。

$args = array(
        \'post_type\'      => \'page\',
        \'posts_per_page\' => -1,
        \'post_parent\'    => 91,
        \'order\'          => \'ASC\',
    );

    $parent = new WP_Query( $args );

    if ( $parent->have_posts() ) :

        echo \'<div class="events_lists_on_page">\';

        while ( $parent->have_posts() ) : $parent->the_post();

             //grab the menu item data
             $image_uploaded_meta_id = get_post_meta($post->ID, \'_listing_image_id\', true);
             $image_thumb_url = wp_get_attachment_image_src($image_uploaded_meta_id, \'full\');

             //grab and save title of post
             $title = get_the_title();

             //grab and save the link to the post
             $link = get_permalink();

             //grab content
             $the_content = get_the_content();

             echo \'<div class="element">\';

             echo \'<img src="\'. $image_thumb_url[0] .\'">\';

             echo \'<div class="text"><p>\' . $title .\'</p></div>\';

             echo \'<p>\'. $the_content .\'</p>\';

             echo \'</div>\';

        endwhile;

        echo \'</div>\';
    endif;
