form validation help PLEASE

[eluser]dadamssg[/eluser]
Flaky, im using multiple controllers. I wanted to seperate my login controller from my mains controller. The mains controller loads that view...the login_view is only a small piece of the overall page. my mains controllers index beginning looks like this

Code:

function index()
    {
        $data['title'] = "Home";
        $data['heading'] = "All Events";
        $this->load->model('Frontmodel');
        $data['query'] = $this->Frontmodel->get_all_events();
        
        $this->load->view('header_view', $data);

        $this->load->view('login_view', $data);
        
        $this->load->view('main_view', $data);
    }

and my login_view form submits to the login controller
