Beginner : extended tree helper to display other fields

[mamato]

Hi,

I was having a problem on displaying other fields for my 'Category'
model using the tree helper, like this

name     description
--------    -----------------
Car        All about cars
-New      New cars
-Used     Pre owned cars

the tree helper can display the first field nicely but not the other
fields in the model. This is my first try, thought I extend the tree
helper a bit to allow other fields to be displayed. Here portion of it
goes;

<pre>

 function show($name, $data,  $arrayOfFields = null))
  {
    list($modelName, $fieldName) = explode('/', $name);
    $output = $this->list_element($data, $modelName, $fieldName, 0,
$arrayOfFields);

    return $this->output($output);
  }

  function list_element($data, $modelName, $fieldName, $level,
$arrayOfFields=null)
  {
    $tabs = "\n" . str_repeat($this->tab, $level * 2);
    $li_tabs = $tabs . $this->tab;

    $output = $tabs. "<ul>";
    foreach ($data as $key=>$val)
    {
          if(!is_null($arrayOfFields)) {
                foreach($arrayOfFields as $key=>$otherField){
                        $text .= '&nbsp ' . $val[$modelName][$otherField];
                }
          }
      $output .= $li_tabs . "<li>".$val[$modelName][$fieldName];
      if(isset($val['children'][0]))
      {
        $output .= $this->list_element($val['children'], $modelName,
$fieldName, $level+1, $arrayOfFields);
        $output .= $li_tabs . "</li>";
      }
      else
      {
        $output .= "</li>";
      }
    }
    $output .= $tabs . "</ul>";

    return $output;
  }
</pre>

Now if only it can be displayed in table format... Comments
appreciated.
