Call model-class from view

[quote author="TheFuzzy0ne" date="1242355718"]That's done by calling views from within a view. You'd have a template which includes the necessary views - header, navigation, body and maybe footer.[/quote]

That is excatly how I did. But since this template is a view file it's no good to call session-variables to that template (if I understood MVC correct).

So if I wanted to check if my user is logged in i need to do it like this in every singel Controller:

Code:

if(session-variable is set) {
$data['login'] = welcome.php;
} else {
$data['login'] = login.php;
}

$data['content'] = mainpage.php;

$this->load->view(template, $data);

That seem like some extra work in every single controller.

And also when I redirecting my users back to the page he was browsing if he get an error message, I need to use a session-variable or something to write some text.

form_validation error message only seem to work if you do $this->load->view('template'); again, which I cannot do because I don't know which page he was browsing.
