CakePHP - 打印帖子的子项，如何

Question

下面是 posts_controller 的调试输出。我目前使用语法：

<?php foreach ($posts as $post): ?> ... <?php endforeach; ?>

打印视图中的帖子，但这只会产生最外面的帖子（即 - 父帖子且不打印子帖子）。

问题：

如何在每个父帖子的正下方打印所有子帖子？ 解决方案是嵌入式 foreach 循环吗？

调试：

Array
(
    [0] => Array
        (
            [Post] => Array
                (
                [active] => 1
                [id] => 1
                [parent_id] => 0
                [created] => 2011-08-06 03:54:07
                [modified] => 2011-08-06 03:54:07
                [text] => a
            )

        [Children] => Array
            (
                [0] => Array
                    (
                        [active] => 1
                        [id] => 3
                        [parent_id] => 1
                        [created] => 2011-08-08 01:54:24
                        [modified] => 2011-08-08 01:54:24
                        [text] => c
                    )

                [1] => Array
                    (
                        [active] => 1
                        [id] => 2
                        [parent_id] => 1
                        [created] => 2011-08-06 03:54:37
                        [modified] => 2011-08-06 03:54:37
                        [text] => b
                    )

            )

    )

)

Answer 1

它是一个嵌入式 foreach 循环解决方案吗？ 呃..是的。我不认为还有其他方法。

foreach（$posts 作为 $post）：
    回声 $post['Post']['id'];
    foreach ($post['Children'] as $child_post){}
  结束foreach； 

Answer 2

$childPosts = Set::extract('/Children', $posts);
