Question

I am using CodeIgniter and I have a route set up as follows:

$route["(:num)"] ="login/login_by_id/$1";

This basically means that when the URL looks like this:

http://mydomain.com/12345

This will effectively pass the value 12345 into the login_by_id method of the login controller. Everything works fine when I enter the URL directly. Where I am having a problem is when I try to load a view. These are the lines which call the view:

$data['content'] = 'login_view';
$data['title']   = 'Login';
$data['error_msg'] = 'Invalid password.  Please try again.';
$this->load->view('login_template', $data); 

My problem is that instead of returning the user back to here:

http://mydomain.com/12345

The browser directs the user to this URL:

http://mydomain.com/login/login_by_id

How can I change the code so that I return my user back to the same URL they were at previously? I don’t want to be showing the controller/method in the URL address.

Thanks.

In the function ( the one which you are calling after hitting the submit button) in controller.

public function post_login()

  {

      $error_in_validation=set_form_validation($this->config->item('login_form'));

        if($error_in_validation){
            show_form_validation_error('controller_name/login');
        }
        else
        {
            $email=$this->input->post('email');
            $passwd=$this->input->post('passwd');
            $ret=$this->admin_model->user_login($email, $passwd);

            if($ret == NULL){

                $model=array();
                $model['error_msg']=$this->config->item('login_form_error_code_1');;
                $this->load->view('login',$model);              
            }
            else{
                redirect("home");
            }

        }

    }
