我认为您需要的是：
<?php
$post_id = $post->ID; //or somehow get the current post ID.
$ancestors = get_post_ancestors($post_id)
//$ancestors is an array of post IDs starting with the current post going up the root
//\'Pop\' the root ancestor out or returns the current ID if the post has no ancestors.
$root_id = (!empty($ancestors) ? array_pop($ancestors): $post_id);

我认为比“亚历克斯·伦纳德”更好的解决方案是使用parent_id post对象的参数。
$parent = ( $post_obj->parent_id != 0 ) ? $post_obj->parent_id : false;
