Multi-level menu with Modified Preorder Tree Traversal

Hi all,

In this well known example, the indention of the levels is done by some  's instead of <ul><li>'s.

I wonder if there's a way to use MPPT (Modified Preorder Tree Traversal) logic to dynamically build those multi-level menu without using any recursion? I can't figure out where I have to close those <ul>'s and <li>'s... :s

Thx!

Re: Stuck on Array issue: $post['Post']['id'] not works now, but $post[0]['id'] is ok

That's strange, findBy<field> is usually the same as doing $this->find('first'), unless you have extended or overridden somewhere?

Try doing the following just to see if it makes a difference? Your issue it seems is that your query is similar to doing $this->find('all') which can have more than one result.

$post = $this->Post->find('first', array('conditions' => array('Post.id' => $id)));

Hi, cakePHPers:

I am an architect, not quite familiar with CakePHP before, recently after an upgrade to CakePHP 2.4.6, $post['Post']['id'] not works now, but $post[0]['id'] is ok.

I am not sure it's caused by CakePHP or other stacks, because I upgraded CakePHP from 2.1 to 2.4.6 , CentOS from 6.0 to 6.5, and PHP upgraded from 5.2.14 to 5.5.10 too.

Here's the code and screenshot:

Model/Post.php
<?php
class Post extends AppModel {
}

Posts/view.ctp:
<h1><?php echo h($post['Post']['title']); ?></h1>
<p><small>Created: <?php echo $post['Post']['created']; ?></small></p>
<p><?php echo $post['Post']['body']; ?></p>

<h1><?php echo h($post[0]['title']); ?></h1>
<p><small>Created: <?php echo $post[0]['created']; ?></small></p>
<p><?php echo $post[0]['body']; ?></p>

PostsController.php:
<?php class PostsController extends AppController {
   public $helpers = array('Html', 'Form');
   public function view($id = null ) {
       $post = $this->Post->findById($id);
       print_r($post);
       $this->set('post', $post);
   }
}

Please let me know what's wrong, the code? the upgrade of CakePHP, or other stack issue. Thanks.
