Greetings forum,

I am trying to create a simple form to be redirected to a URL upon submission. However, I need the user to submit a URL and once they press the submit button, their page redirects to the url they submitted. I have had quite the challenge learning how to do this. If anyone could point me in the right direction, it would be appreciated.

Many thanks,

Robert Williams

rmw603,
You will need a controller, that may look like this:

Code:
class Welcome extends CI_Controller {

    function __construct() {

        parent::__construct();

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

        $this->load->helper('url');

        $this->load->helper('form');

    }

    /**

     * Index Page for this controller.

     *

     * Maps to the following URL

     *         http://example.com/index.php/welcome

     *    - or -  

     *         http://example.com/index.php/welcome/index

     *    - or -

     * Since this controller is set as the default controller in 

     * config/routes.php, it's displayed at http://example.com/

     *

     * So any other public methods not prefixed with an underscore will

     * map to /index.php/welcome/<method_name>

     * @see http://ellislab.com/codeigniter/user-guide/general/urls.html

     */

    public function index()

    {

        //$this->load->view('welcome_message');

        $this->form_validation->set_rules('field0','URL','required');

        IF ($this->form_validation->run()===FALSE) {

            $this->load->view("form");

        }

        ELSE {

            redirect($this->input->post('field0'));

            exit;

        }

    }

}

/* End of file welcome.php */

/* Location: ./application/controllers/welcome.php */

and your view may look like this:

Code:
&lt;html&gt;

&lt;head&gt;

    &lt;title&gt;Form Title&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;?PHP

echo form_open('welcome/index');

?&gt;

<h1>URL:</h1><br />

&lt;?PHP

echo form_input('field0','http://www.google.com');

?&gt;

<br />

&lt;?PHP

echo form_submit('submit','Go To Site!');

echo form_close();

?&gt;
