Create a library named MY_Controller.php and place in your system/application/libraries
and paste the code below

Code:
class Front_Controller extends Controller

{

    var $current_culture='';

    function Front_Controller()

    {

        parent::Controller();

        if($this->session->userdata('language'))

        {

            $this->config->set_item('language',$this->session->userdata('language'));

            $this->config->set_item('language_code',$this->session->userdata('language_code'));

        }

        $this->current_culture=$this->config->item('language');

        $this->culture_code=$this->config->item('language_code');

    }

    function set_current_culture($language)

    {

            $this->session->set_userdata('language',strtolower($language));

        }

    }

}

Create your controller and extend it with Front_Controller class

For example:

Code:
class Home extends Front_Controller

{

    function Home()

    {

        parent::Front_Controller();

    }

    function index()

    {

        $data['title']='Switch Language Example';

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

    }

    // Function if you are doing post from FORM

    function language()

    {

        $this->set_language($this->input->post('currlang'));

    }

    //Function if you are selecting from the Link

    function set_language($language_code)

    {

        $this->set_current_culture($language_code);

        redirect(site_url('home'));

    }

}

And create home.php and place in the views:

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

&lt;html &gt;

&lt;head&gt;

&lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;

&lt;title&gt;Switch Language Developed By Dixanta Shrestha&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;form name="form_lang" action="&lt;?=site_url('home/language')?&gt;"&gt;

 <select name="currlang" id="currlang">

                                    <option value="en" &lt;? echo ($this->config->item('language')=='english')?'selected':'';?&gt;>English</option>

                                    <option value="fr" &lt;? echo ($this->config->item('language')=='french')?'selected':'';?&gt;>French</option>

                                    <option value="nl" &lt;? echo ($this->config->item('language')=='dutch')?'selected':'';?&gt;>Dutch</option>

                                </select>

&lt;/form&gt;

&lt;input type="submit" name="submit" value="Go"/&gt;

 <ul>

                                <li><a href="&lt;?=site_url('home/set_language/frech')?&gt;">French</a></li>

                                <li><a href="&lt;?=site_url('home/set_language/english')?&gt;">English</a></li>

                                <li><a href="&lt;?=site_url('home/set_language/dutch')?&gt;">Dutch</a></li>

                          </ul>

&lt;/body&gt;

&lt;/html&gt;

You are done.
