Call model-class from view

I am still stuck!

If you need a better explanation of my problem, here we go:

Controller, users.php:

Code:

<?php

class Users extends Controller {

    function Controller()
    {
        parent::Controller();
    }

    function login() {
        // Here I should call the model to check if the user exists or not.
        if(user exists and the username and password was correct)
        {
            start session and set session-variables.
            redirect('the page the user was browsing but with session var set.');
            // How do I know which page he was browsing?
        }
        else
        {
            give error message.
        }
    }
}

View, login.php:

Code:

<?php echo validation_errors(); ?>
<?php echo form_open('Users/login'); ?>
    <input type='text' name='login' class='login' value='Användarnamn'>

    <input type='password' name='password' class='login' value='Lösenord'>

    <input type='submit' value='Logga in' class='loginsub' />
</form>

To clarify things, the login.php is just one of the views I load at each page. In my first post you can see my template view!

In my view file login.php I would like to add if he is logged in, show a welcome text, if not show the login formula. Is it good coding or shouldn't the view know anything about sessions aswell?

Sorry for all those questions, but I'm totally new trying to redo my webpage in code igniter. I've read the manual a few times but everything isn't clear.
