假设您知道（或知道如何获得）$id （作为父帖子的整数），使用the post_parent parameter:

$albums = new WP_Query(array(
    \'post_type\' => \'gallery\',
    \'posts_per_page\' => 6,
    \'post_parent\' => $id
));

我不知道家长的帖子。我想列出任何父页面中最近的子页面。

虽然只查询父页面很容易（通过传递\'post_parent\' => 0), 只查询子页面并不是那么简单。

一种方法是查询所有gallery 帖子，循环浏览，并添加任何具有post_parent 转换为另一个变量；然后输出该变量。

// Query all gallery posts
$all_albums = new WP_Query( array(
    \'post_type\' => \'gallery\',
    \'posts_per_page\' => -1
) );

// Array to hold latest albums
$latest_child_albums = array();
// Latest album counter
$latest_albums_count = 0;
// If we already have 5, no need to keep looping
while ( 5 < $latest_albums_count ) {
    // Loop through each gallery post
    foreach ( $all_albums as $album ) {
        // If the current post has a parent
        if ( $album->post_parent != 0 ) {
            // Add it to the latest albums array
            $latest_child_albums[] = $album;
            // Increment the counter
            $latest_albums_count++;
        }
    }
}

// Loop through the array of latest albums
if ( $latest_child_albums->have_posts() ) : while ( $latest_child_albums->have_posts() ) : $latest_child_albums->the_post();
    // Loop content here
endwhile; endif;
// Be kind; rewind.
wp_reset_postdata();
