Kohana bool(false)

[Lobezki]

При переходе на url необходимой мне категории пишет bool (false).

 public function getCategoryIdByUrl($url)
  {
   $data = DB::select('id')
  ->from($this->tableName)
  ->where('url', '=', $url)
  ->execute()
  ->current();
  
  var_dump($data);
  exit;
      
  if (!isset($data['id'])) return FALSE;
  return $data['id'];
  }

  public function action_index()
  {
   $category = new Model_Category('tree');
   $data['categories'] = $category->getTree();  
  
  if(isset($_POST['btnsubmit']))
  {
  $categoryName = Arr::get($_POST, 'categoryName', '');
  $parentId = Arr::get($_POST, 'parentId', '');  
  $url = Arr::get($_POST, 'url', '');

  $res = $category->catInsert($parentId, array('name'=>$categoryName, 'url'=>$url));  

  if($res)
  {
  Controller::redirect($uri ='admin');
  }
  else
  {
  $data['errors'] = $category->getErrors();
  }
  }
  
   $this->template->content =  View::factory('adminview', $data);
  }

public function action_category($url = NULL)
   {
     $data = array();
    
     $category = new Model_Category('tree');
     //$material = new Model_Material();
    
     $category_id = $category->getCategoryIdByUrl($url);
     if(!$category_id) $this->request->redirect('');

     $data['Materials'] = $material->getMaterialsByCategory($category_id);

     $this->template->content =  View::factory('materialsview', $data);  
   }
