How to call function in controller from view in CodeIgniter?

Question

My controller is like this :

public function index()
{
    $data_login = $this->session->userdata('login');
    $id = $data_login['customer_id'];

    $this->data['notification'] =  $this->get_data($id);    

    $this->load->view('notification/list_view', $this->data);
}

public function time_elapsed_string($datetime, $full = false) 
{
    ...
}

My view (list_view) is like this :

<table class="table table-striped table-advance table-hover">
    <tbody>
    <?php
        foreach ($notification as $key => $value) 
        {
    ?>

        <tr class="unread" data-messageid="1">
            <td class="view-message "> 
                <?php
                    echo '<a href='.base_url().'notification/notif/'.$value['notification_id'].'>'.$value['notification_message'].'</a><br>';
                ?>
            </td>
            <td class="view-message text-right"> <?php echo $this->time_elapsed_string($value['notification_created_date']); ?> </td>
        </tr>

    <?php
        }
    ?>
    </tbody>
</table>

When executed, there exist error like this :

Fatal error: Call to undefined method EX_Loader::time_elapsed_string().....

Seemed unable to call function time_elapsed_string in controller.

Any solution to solve my problem?

I believe, you can't use controller's method in view. You have to have helper function.

So, create a helper.php file then, make your function as below:

if ( ! function_exists('time_elapsed_string')){
    function time_elapsed_string($datetime, $full = false){
        // do your calculation 
        return 'something';
    }
}

Then include your helper.php file into your controller as below:

$this->load->helper('helper');

Now you will be able to use that "time_elapsed_string" function in your view.

you can't call $this function in view, you can use normal function and helper function.

best solution is use function in controller and use return value in view.
