public function register()
    {

        $this->load->view('users/register');
        $this->load->view('templates/footer');
       
        $this->load->library('form_validation');

       
        if(!empty($this->input->post('email'))){
                $this->load->model('User_model');  
                if($this->User_model->getUserEmail($this->input->post('email')))
                {  
                    $data = array(
                       'fname' => $this->input->post('fname'),
                       'lname' => $this->input->post('lname'),
                       'email' => $this->input->post('email')
                    );
                    $this->db->insert('users', $data);
                    $userId = $this->db->insert_id();
                   
                    $this->load->model('Ticket_model');
                    $tktToken = $this->Ticket_model->generateToken($userId);
               
                    $this->sendmail($userId,$this->input->post('email'),$this->input->post('name'),$tktToken,'register','Verify your email');
                    redirect('users/index', 'refresh');
                }else{
                    $this->session->set_flashdata('msg', 'This email is already used, please try again with different account ...');
                    redirect('users/register', 'refresh');
                }
           
        }
    }

You can use html templates to send mail, which already explained in previous mail i.e. send email using HTML templates in Codeigniter.

<?php
class Ticket_model extends CI_Model
{
    function __construct()
    {
        parent::__construct();
    }
   
    public function generateToken($userId,$tktReason='register'){
        $static_str='AL';
        $currenttimeseconds = date("mdY_His");
        $token_id=$static_str.$userId.$currenttimeseconds;
        $data = array(
                 'tktToken' => md5($token_id),
                 'tktReason' => $tktReason,
                 'userId' => $userId,
                 );
     $this->db->insert('tickets', $data);
        return md5($token_id);
     }
}
?>

After token generation mail will be send to respective user’s email with token key link. We can confirm that token with below code

        $userId = $this->Ticket_model->checkToken($this->uri->segment(3),'register');
       
        if($userId !=''){
            $sql = "SELECT * FROM users WHERE userId = ?";
            $results = $this->db->query($sql, array($userId));
            $loginData = $results->row();
           
            $dataupdate = array(
                   'updated'=> gmdate("Y-m-d H:i:s"),
                   'status'=>1
                   );
            $this->db->where('userId', $userId);
            $this->db->update('users', $dataupdate);
               
            $this->db->where('tktToken', $this->uri->segment(3));
            $this->db->where('tktReason', "register");
            $this->db->delete('tickets');
            $sess_array = array(
                                'userId' => $loginData->userId,
                                'email' => $loginData->email
                                );
               $this->session->set_userdata('logged_in', $sess_array);
               $this->session->set_flashdata('msg', 'You has been confirmed as member');
               redirect('users/index', 'refresh'); 
        }
        else{
            $this->session->set_flashdata('msg', 'Your request process not success, You entered with an incorrect code');
            redirect('users/index', 'refresh');
            }
       
    }

Hope it will help in your CodeIgniter applications.
