Codeigniter: Load data from controller_1 to view_1 after it has been passed to controller_2

Question

This seems simply but can't find an answer. I have a login controller with a data title variable:

$data['title'] = 'Login here';
$this->load->view('login/login_view', $data);

The view is loaded correctly with the:

<title>Login here</title>

Cool! But when I login using the form and send the data to the "login_verify" controller it checks to see if there is a match or if the fields were populated and if false it returns to the original login view:

function index() { 
   $this->load->library('form_validation');

   $this->form_validation->set_rules('username', 'Username', 'trim|required');
   $this->form_validation->set_rules('password', 'Password', 'trim|required|callback_check_database');

   if($this->form_validation->run() == FALSE) {
     //Field validation failed.  User redirected to login page
     $this->load->view('login/login_view');
  } else {
    //Go to private area
    redirect('home', 'refresh');
  }
}

How do I get the original $title variable back into the login view if the validation fails? Do I redeclare the original login controller before I load the login view? If so, how? Obviously I don't want to have to redefine the $title variable in the "login_verify" controller.

Thanks

There's really not a way to do it without either re declaring the title variable, or setting a session up. Instead of $this->load->view('login/login_view'), why not just redirect back to the login screen redirect('login')? Or if you want to get really fancy, you could make that function an ajax function, and pass the form in through javascript instead of having the user reload their page.

On a side note: You really don't need a separate controller for "login_verify", you can do all of that from the original "login" controller and just make a function called "verify", which you can then get to by navigating to "login/verify". You want your controllers to be broad, but specific to a group of actions.
