$this->load->library('form_validation');

$this->form_validation->set_rules('fname','First Name','required');
$this->form_validation->set_rules('lname','Last Name','required');
$this->form_validation->set_rules('username','username','required');
$this->form_validation->set_rules('password','Password','required');
$this->form_validation->set_rules('cpassword','Confim Password','required|matches[password]');

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

    $this->load->model('Registration');

    $this->Registration->create(
        ['fname' => ucfirst($_POST['fname']),
         'lname' => ucfirst($_POST['lname']), 
         'username' => ucfirst($_POST['username']),
         'password' => md5($_POST['password'])]);   

    redirect(base_url().'templates/rsuccess', 'location', 301);


} else {
$view_data['page_title'] = 'Register first';
$view_data['errors'] = $this->form_validation->error_array();

$this->load->view('templates/header', $view_data);
$this->load->view('auth/registration');
$this->load->view('templates/footer');

}
}
