Call function from "views"

[eluser]gtech[/eluser]
you can default the variables, so that if .../12/24 are chopped off or 24 is chopped off it will default to 0

Code:

class Main extends Controller{    
    function diff($n1=0, $n2=0){
            $diff['res'] = $n1 - $n2;
        $this->load->view('main_diff', $diff);
    }
}

OR

you can temporary store the variables in the session.

OR

you can post the variables though a form as hidden values.

[edit]

if you are just calling the function then do as Jondolar said, I thought you wanted to call the function through a request.
