Passing a variable on redirect

[eluser]The Revel[/eluser]
Ok, I managed to do it this way:

In the top part, I added the value to the session data:

Code:

//redirect them to the login page
            $this->session->set_userdata('searchcode', $this->input->post('searchcode', true));
            
   redirect('auth/search_scancode/', 'refresh');

So that when it redirects it checks for the post variable, if it doesn;t exist grab it from the session, and then delete the session:

Code:

if ($this->input->post('searchcode', true))
         {
          $searchcode = $this->input->post('searchcode', true);  
         }
          else
          {
            $searchcode = $this->session->userdata('searchcode');
            $this->session->unset_userdata('searchcode');
          }

This seems to work ok.
