Call model-class from view

[quote author="Dam1an" date="1242181426"]The way I do it is
1. On every page (that you need to be logged in to see) check if the user is logged in
2. If they're not logged in, get the current URI string, and save it to session
3. Redirect to login (and display a "You need to be logged in to see that page" message)
4. Process the login attempt, and on successful login, redirect to the URI string you saved to session (and unset it)[/quote]

You know my login-form is to the left on every singel page of my website. And when you login I just want that login-part of the page to refresh and there will appear a welcome message. The other parts of my homepage you are browsing should consist.

So my controller-function login should call for following view-files:

Code:

$this->load->view('header');
$this->load->view('top');
$this->load->view('menu');
$this->load->view('welcome_msg');
$this->load->view($content);
$this->load->view('footer');

My problem here is that I do not know what they were currently browsing, so I do not know what I should set my $content variable to.
