Cake PHP将链接添加到树输出

Question

I am trying to add links to a Tree output list.

In addition to the links I get the &nbsp's included in the output

So that it looks like this:

**My Categories
   Fun
      Sport
         Surfing
         Extreme knitting**

etc.....

I don't want that obviously, but I do want to keep the nested output relationship.

Below is code:

Controller

<?php

class CategoriesController extends AppController {
 public $helpers = array('Html', 'Form');

    public function index() {

      $this->set('output', $this->Category->generateTreeList(null, null, null, '&nbsp;&nbsp;&nbsp;'));
    }
}

?>

View

<?php foreach ($output as $data): ?>
<ul>

<?php echo $this->Html->link($data,
array('controller' => 'data', 'action' => 'view', $data)); ?>



</ul>
    <?php endforeach; ?>
    <?php unset($data); ?>

You should use a tree helper to output your tree as ul/li including links. See http://www.dereuromark.de/2013/02/17/cakephp-and-tree-structures/

generateTreeList() - as documented - is a quick way to create a dropdown select ready list, not a tree.
