控制器：

        public function index() {
            $this->login();
        }

        public function login() {
            $this->load->helper('form');
            $this->load->library('form_validation');

            $data['title'] = "Login";

            $this->form_validation->set_rules('','','');
            $this->form_validation->set_rules('','','');

            if($this->form_validation->run() === FALSE) {

            } else {
                $this->authenticateuser();
            }
        }

        public function authenticateuser() {
            $username = $this->input->post('idNumber');
            $password = md5($this->input->post('passWd'));

            $query = $this->db->query("select * from users where idNumber='".$username."' and passWd='$password'");
            $row = $query->num_rows();

            if($row) {
                $this->session->set_userdata(array('username' => $username));
                $sessionID = $this->session->userdata('username');
                $data['title'] = 'Dashboard';

                $this->load->view('dashboard', $data);
            } else {

        }

        public function logout() {
            $this->session->unset_userdata('username');
            redirect('login');
        }

        // handles register page
        public function register() {
            $this->load->view('register');

            if($this->input->post('register')) {
                $username=$this->input->post('userid');
                $password=md5($this->input->post('pass'));

                $this->System->registeruser($username, $password);
                echo "User Registration Complete";
