Undefined function when calling extended helper function in Codeigniter

Question

I create MY_form_helper.php in application/helpers/, extending form_helper.php. The function is like this:

function alert($message,$type = 'success'){
    $data = array(
        'type' => $type,
        'text' => $message
    );
    return json_encode($data);
}

In my controller I call the function like this:

$this->load->helper(array('form', 'url'));
echo alert('Wrong email or password');

but it gives me an error

Message: Call to undefined function alert()

so what am I missing or doing wrong here?

Place your MY_form_helper.php helper to application/helper

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

   function alert($message,$type = 'success'){
      $data = array(
        'type' => $type,
        'text' => $message
   );
   return json_encode($data);
}

and in your Controller place this code.

public function sample()
{
    $this->load->helper('MY_form_helper'); //load your helper

    echo alert('Wrong email or password'); //call your function
}

Let me know the result.

It should be working just fine as it is IF you stored it in the right directory which is application/helpers with the name MY_form_helper.php now you it should add the extension to the core helper:

$this->load->helper('form');
var_dump(alert('Wrong email or password'));
