我不确定我在这里做错了什么。我有一个名为“grid\\u缩略图”的字段和一个“related\\u projects”post\\u对象。我能够显示相关帖子的标题。我只是不知道如何获取相关帖子的图片URL。建议？
<?php foreach(get_field(\'related_projects\') as $post_object): ?>
<li>
<img src="<?php echo get_field(\'grid_thumbnail\'); ?>"><br />
<a href="<?php echo get_permalink($post_object->ID); ?>"><?php echo get_the_title($post_object->ID) ?></a>
</li>
编辑打印返回：
