下面是一个小部件，里面有一个Wordpress循环。它按预期工作。唯一的问题是这部分：

\'post_parent\' => $post->ID,

小部件未获取post->ID 当前的父级的topic 自定义帖子类型（with是另一个自定义帖子类型，名为forum).

当我将循环放置在模板文件中时，它确实起作用。这是：

<?php $current_post_id = $post->ID; ?>

<h2><?php echo $current_post_id; ?></h2>

输出帖子id（论坛自定义帖子类型，它是主题自定义帖子类型的父级）。

有没有解决这个问题的建议？

$args = array(
    \'post_type\' => \'topic\',
    \'posts_per_page\' => \'3\',
    \'post_parent\' => get_the_ID(),
    \'gdsr_sort\' => \'thumbs\',
    \'gdsr_ftvmin\' => \'1\',
    \'gdsr_order\' => \'desc\',
    \'order\' => \'DESC\'
);

$query = new WP_Query($args);


if($query->have_posts()) :
    while ( $query->have_posts() ) : $query->the_post();
        // do your stuff
    endwhile;
endif;
