如何在功能擴展控制器中獲取數據？

Question

我的控制器是這樣的：

<?php if (!defined('BASEPATH')) exit('No direct script access allowed'); 

class Dashboard extends EX_Controller 
{ 
    public function __construct() 
    { 
     parent::__construct(); 
    } 

    public function index() 
    { 
     $this->data['news'] = $this->dashboard_model->get_news(); 
     $this->load->view('dashboard/index_view', $this->data); 
    } 

我EX_Controller是這樣的：

<?php 
class EX_Controller extends CI_Controller 
{ 
    public $data; 
    public function __construct() 
    { 
     parent::__construct(); 

     $this->load->model('notification_model'); 
     $this->get_notification(); 
    } 

    public function get_notification() 
    { 
     $session = $this->session->userdata('login'); 
     $this->data['notification'] = $this->notification_model->get($session); 
     $this->data['count_notification'] = $this->notification_model->get_count_notification($session['customer_id']); 
    } 
} 
?> 

我的索引視圖是這樣的：

<?php 
    foreach ($notification as $value) { 
?> 
     <li> 
     <?php 
      echo '<a href='.base_url().'notification/notif/'.$value['notification_id'].'>'; 
     ?> 
       <span class="time"> 
       <?php 
        echo time_elapsed($value['notification_created_date']); 
       ?> 
       </span> 
       <span class="details"> 
        <span class="label label-sm label-icon label-info"> 
         <i class="fa fa-bookmark"></i> 
        </span> <?php echo $value['notification_message']; ?> 
       </span> 
      </a> 
     </li> 
<?php 
    } 
?> 

當被執行時，存在錯誤：

Message: Undefined variable: count_notification 
Message: Undefined variable: notification 

看來它不能調用get_notification功能EX控制器

我把功能get_notification(EX Controller)在所有控制器

讀取任何解決方案來解決我的問題呢？

這個問題的解決方法就是使用：

$this->load->model('notification_model'); 
$this->get_notification();
