Here you go. A bit late for the author, but people will come here for an answer still ;-)
干得好。作者有点晚了，但人们还是会来这里寻求答案;-)
<?php
// determine parent of current page
if ($post->post_parent) {
$ancestors = get_post_ancestors($post->ID);
$parent = $ancestors[count($ancestors) - 1];
} else {
$parent = $post->ID;
}
$children = wp_list_pages("title_li=&child_of=" . $parent . "&echo=0");
if ($children) {
?>
<ul class="subnav">
<?php
// current child will have class 'current_page_item'
echo $children;
?>
</ul>
<?php
}
?>

The easiest way to handle this is with get_children(). It pretty much does what you would expect. It returns the child pages of a parent page.
处理此问题的最简单方法是使用get_children(). 它几乎可以满足您的期望。它返回父页面的子页面。
get_children()is basicly a wrapper for the WP_Queryclass.
get_children()基本上是WP_Query类的包装器。
You can use it like this...
你可以这样使用它......
$child_args = array(
'post_parent' => 1, // The parent id.
'post_type' => 'page',
'post_status' => 'publish'
);
$children = get_children( $child_args );
If you want to return the children of the current post you can pass in $post->IDas the 'post_parent'.
如果你想返回当前帖子的孩子，你可以$post->ID作为'post_parent'.
