Call model-class from view

[eluser]juan1904[/eluser]
Hm so all I need to do is to call a model which choose the view to load (login.php or welcome.php). Seem to make sense!

Just one more problem then. When I use form_validation in my login-controller the code is something like this:

Code:

function login()
{
$login = $this->input->post('login');
$password = $this->input->post('password');

$this->form_validation->set_rules('login', 'användarnamn', 'callback_user_exists');
$this->form_validation->set_rules('password', 'lösenord', 'callback_user_exists');

$prev_page = $this->input->server('HTTP_REFERER');

if ($this->form_validation->run() == TRUE)
{
// Set some session-variables.
redirect($prev_page);
}
else
{
redirect($prev_page);
}
}

function user_exists($login, $password)
{
if(user exists i database) {
return TRUE;
} else {
$this->form_validation->set_message('user_exists', 'Fel %s.');
return FALSE;
}
}

I don't know how to use form_validation to outprint error messages in my login.php here. If I load the template view file I don't know which content the user were browsing.

Another question: Should I put all these validation code in a model instead? I'm not really sure in which situations to use models and which to use controllers.
