controller function form validation


I have the controller below and I would like it do the following things:

Show an error if the username is taken -> currently just submits as normal even through the specific user is in the database.

Populate with data if there was an error -> currently populates with the imported data if correct

Keep active state of the selected drop down menu item


<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class createUser extends CI_Controller {

public function index()
  //Form Validation prep making sure its all clean
  $this->form_validation->set_rules('userName', 'User Name', 'trim|required|is_unique[users.userName]|xss_clean');
  $this->form_validation->set_rules('userPassword', 'User Password', 'trim|required|xss_clean|sha1');
  $this->form_validation->set_rules('userFirstName', 'First Name', 'trim|required|xss_clean');
  $this->form_validation->set_rules('userLastName', 'Last Name', 'trim|required|xss_clean');
  $this->form_validation->set_rules('userEmail', 'E-Mail', 'trim|required|xss_clean');
  $this->form_validation->set_rules('userGroup', 'User Group', 'trim|required|xss_clean');
  $this->form_validation->set_rules('userActive', 'User Active', 'trim|required|xss_clean');
  //If form validation fails load previous page with errors else do the job and insert data into db
  if($this->form_validation->run() == FALSE)
   $data['success'] = "";
   $username = $this->input->post('userName');
   $password = $this->input->post('userPassword');
   $firstname = $this->input->post('userFirstName');
   $lastname = $this->input->post('userLastName');
   $email = $this->input->post('userEmail');
   $group = $this->input->post('userGroup');
   $active = $this->input->post('userActive');
   $passwordHash = $this->encrypt->sha1($password); // Lets encrypt the password why sha1?  MD5 is for tossers
   // If the data is correct follow through with db insert
    $data['success'] = TRUE;
  $data['companyName'] = $this->core_model->companyName();
  $data['pageTitle'] = "Create User";
  $this->load->view('admin/assets/header', $data);
  $this->load->view('admin/createUser', $data);

/* End of file login.php */
/* Location: ./application/controllers/admin/createUser.php */
