Example
have code

Code:
$this->load->library('form_validation');

if ( $res !== false ) {

    $_SESSION['username'] = $this->input->post('email_address');

    //insert here set_message "Success"

    $this->form_validation->set_message('success_login', 'Login success');

            } else {

    echo "Incorrect";

   }

used

Code:
$this->form_validation->set_message('success_login', 'Login success');

and added $lang['success_login'] = "Success login."; in form validation lang and does not display message.
What is not correct?

The set_message() function is used to display error messages (See http://ellislab.com/codeigniter/user-guide/libraries/form_validation.html#settingerrors for setails).

To display a success message

1) You can use the success page

or:

2) Create two helper functions (in a file helpers/utils_helper.php, for example)

Code:
/**

 * Sets a feedback message as flashdata

 * @param string $feedback

 */

function set_feedback($feedback)

{

 $CI =& get_instance();

 $CI->session->set_flashdata('feedback', $feedback);

}

/**

 * Gets the feedback data set by set_feedback($feedback)

 * @return the feedback message or FALSE if it is not set

 */

function feedback()

{

 $CI =& get_instance();

 return $CI->session->flashdata('feedback');

}

3) On success call <b>set_feedback('Login success');</b>

4) Somewhere in your view insert

Code:
&lt;?php if($feedback): ?&gt;

<div id="feedback">

  &lt;?=$feedback?&gt;

</div>

&lt;?php endif?&gt;

5) load your view

Code:
$this->load->helper('utils');

...

$data['feedback'] = feedback();

$this->load->view('your_view', $data);

I hope this helps.
