form validation help PLEASE

[eluser]dadamssg[/eluser]
yeah this is getting really confusing because i have a working site using no framework thats pretty involved. And now im trying to recreate it using codeigniter. What i'm really trying to do is create a login form to display if they're not logged in and if they are a link to their profile, inbox, and notifications. I want to display this at the top of every page so i thought i would do it like this..

*this isnt a working example just my theory

for my mains controller

Code:

<?php

class Mains extends Controller {

    function Mains()
    {
        parent::Controller();
        $this->load->helper('url');
        $this->load->helper('date');
        $this->load->helper('text');
        $this->load->helper('form');
        $this->load->library('session');
        $this->load->library('form_validation');
    }

    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);



                if(logged in)
                {///load the login form in the header
        $this->load->view('login_view', $data);
        }
                else
                {//load the logged in portion with the profile/inbox/notification links
                 $this->load->view('logged_view', $data);
                }

                //then load the main content
        $this->load->view('main_view', $data);
    }
    
    function performance()
    {
        $data['title'] = "Performance";
        $data['heading'] = "Performance Events";
        $this->load->model('Frontmodel');
        $data['query'] = $this->Frontmodel->get_category_events('performance');
        
        $this->load->view('header_view', $data);

if(logged in)
                {///load the login form in the header
        $this->load->view('login_view', $data);
        }
                else
                {//load the logged in portion with the profile/inbox/notification links
                 $this->load->view('logged_view', $data);
                }

                //then load the main content

        $this->load->view('main_view', $data);    
    }
    
    function sports()
    {
        $data['title'] = "Sports";
        $data['heading'] = "Sports Events";
        $this->load->model('Frontmodel');
        $data['query'] = $this->Frontmodel->get_category_events('sports');
        
        $this->load->view('header_view', $data);

if(logged in)
                {///load the login form in the header
        $this->load->view('login_view', $data);
        }
                else
                {//load the logged in portion with the profile/inbox/notification links
                 $this->load->view('logged_view', $data);
                }

                //then load the main content

        $this->load->view('main_view', $data);    
    }
    function organization()
    {
        $data['title'] = "Organizational";
        $data['heading'] = "Organization Events";
        $this->load->model('Frontmodel');
        $data['query'] = $this->Frontmodel->get_category_events('organization');
        
        $this->load->view('header_view', $data);

if(logged in)
                {///load the login form in the header
        $this->load->view('login_view', $data);
        }
                else
                {//load the logged in portion with the profile/inbox/notification links
                 $this->load->view('logged_view', $data);
                }

                //then load the main content

        $this->load->view('main_view', $data);    
    }
    function random()
    {
        $data['title'] = "Random";
        $data['heading'] = "Random Events";
        $this->load->model('Frontmodel');
        $data['query'] = $this->Frontmodel->get_category_events('random');
        
        $this->load->view('header_view', $data);

if(logged in)
                {///load the login form in the header
        $this->load->view('login_view', $data);
        }
                else
                {//load the logged in portion with the profile/inbox/notification links
                 $this->load->view('logged_view', $data);
                }

                //then load the main content

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