Page refresh (F5) always causing form to submit

Question

a bit new to CI, googled and overflowed alot and still got no answer

1. User enters site.
2. After succesful auth got redirected to main page
3. Link on the url stays the same with class/method
4. If u refresh page on a main - u always got question about repopulate form (chrome/firefox 100%)

the solution may be: after success redirect to another class or method

but i don't know how to do it, documentation seems more like reference to me

code is here: http://paste.ubuntu.com/696751/ line 28 - how to do redirect to another class or method with a redirection to another view too?

Answer 1

Well an example in CodeIgniter may be:

class login extends CI_Controller
{
    function index ()
    {
        $this->load->library('form_validation');
        $this->load->helper('url');
        //Set form validation rules here: http://codeigniter.com/user_guide/libraries/form_validation.html
        if ($this->form_validation->run() == TRUE)
        {
            //login user here



            redirect('login/sucLogin'); // or just redirect to '/' if you want to send them to your home page
        }
        else
            $this->load->view('loginForm'); //make form
    }
    function sucLogin ()
    {
        echo 'Successfully logged in';
        echo anchor('/', 'Go Home');
    }
}

Answer 2

1. Check to see if the user submitted the form
2. Validate the login credentials

3. Redirect on success

   public function login() { if ($_POST) { $login = $this->input->post('login'); $password = md5($this->input->post('password'));

       $q = $this->db
           ->where('login', $login)
           ->where('password', $password)
           ->limit(1)
           ->get('userbase');
   
       if ($q->num_rows > 0 )
       {
           redirect('enter/main');
       }
   }
   
   $returnlogin['login'] = $login;
   $this->load->helpers('form');
   $this->load->view('login_form',$returnlogin);
   

   }

   public function main() { $this->load->view('main'); }
