Проверка формы не работает в моем проекте CI (исправлено, код обновлен)

Я новичок в CodeIgniter. Я пытаюсь реализовать проверку формы при регистрации пользователя.

$autoload['libraries'] = array('database','session','encrypt','form_validation');

$autoload['helper'] = array('url','file','form');

$autoload['model'] = array('user_model');

Код контроллера:

class User_registration extends CI_Controller {

public function index() {

$this->register();
}

function register() {

//set validation rules
$this->load->library('form_validation');

$this->form_validation->set_rules('user_name', 'First Name', 'trim|required|alpha|min_length[3]|max_length[30]|xss_clean');
$this->form_validation->set_rules('email_id', 'Email ID', 'trim|required|valid_email|is_unique[email_id]');
$this->form_validation->set_rules('user_password', 'Password', 'trim|required|matches[confirm_password]|md5');
$this->form_validation->set_rules('confirm_password', 'Confirm Password', 'trim|required|md5');

//validate form input

if ($this->form_validation->run() == FALSE) {
// fails
$data = array();
$data['title'] = 'Registration | Admin Panel';
$data['header_content'] = $this->load->view('adminEntry/header_content', '', true);
$data['footer_content'] = $this->load->view('adminEntry/footer_content', '', true);

$this->load->view('adminentry/user_registration', $data);
} else {

//insert the user registration details into database

echo '<pre>';
print_r($data);
exit();

$data = array(
'user_name' => $this->input->post('user_name'),
'email_id' => $this->input->post('email_id'),
'password' => $this->input->post('user_password'),

);if ($this->user_model->insertuser($data)) {

if ($this->user_model->sendEmail($this->input->post('email_id'))) {
// successfully sent mail
$this->session->set_flashdata('msg', '<div class="alert alert-success text-center">You are Successfully Registered! Please confirm the mail sent to your Email-ID!!!</div>');
redirect('user_registration');
} else {
// error
$this->session->set_flashdata('msg', '<div class="alert alert-danger text-center">Oops! Error.  Please try again later!!!</div>');
redirect('user_registration');
}
} else {
// error
$this->session->set_flashdata('msg', '<div class="alert alert-danger text-center">Oops! Error.  Please try again later!!!</div>');
redirect('user_registration');
}
}
}

Модель пользователя:

class User_model extends CI_Model {

//insert into user table
function insertUser($data) {

return $this->db->insert('user', $data);
}

function sendEmail($to_email) {
$from_email = '[email protected]'; //change this to yours
$subject = 'Verify Your Email Address';
$message = 'Dear User,<br /><br />Please click on the below activation link to verify your email address.<br /><br /> http://example.com/user/verify/' . md5($to_email) . '<br /><br /><br />Thanks<br />Mydomain Team';

//configure email settings
$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.example.com'; //smtp host name
$config['smtp_port'] = '465'; //smtp port number
$config['smtp_user'] = $from_email;
$config['smtp_pass'] = 'examplepass'; //$from_email password
$config['mailtype'] = 'html';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;
$config['newline'] = "\r\n"; //use double quotes
$this->email->initialize($config);

//send mail
$this->email->from($from_email, 'example.com');
$this->email->to($to_email);
$this->email->subject($subject);
$this->email->message($message);
return $this->email->send();
}

//activate user account
function verifyEmailID($key) {
$data = array('approval_status' => 1);
$this->db->where('md5(email_id)', $key);
return $this->db->update('user', $data);
}

}

Вот моя ошибка:
