sending token to email in codeigniter - php

Question

I'm working on a small application that can provide registering an account and sending token to complete registration to email.
I have everything working except sending emails with which I can't handle and I'm not sure how to do this. I'd really appreciat any help and explanations on how can I actually send an email instead of just displaying token in view.
There are 2 functions in which I want to send token via mail: register and forgot.
This is my Controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Main extends CI_Controller {
public $status;
public $roles;
function __construct(){
parent::__construct();
$this->load->model('User_model', 'user_model', TRUE);
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
$this->status = $this->config->item('status');
$this->roles = $this->config->item('roles');
}
public function index()
{
if(empty($this->session->userdata['email'])){
redirect(site_url().'/main/login/');
}
/*front page*/
$data = $this->session->userdata();
$this->load->view('header');
$this->load->view('index', $data);
$this->load->view('footer');
}
public function ankieta()
{
$data = $this->session->userdata();
$this->load->view('ankieta/header');
$this->load->view('ankieta/ankieta', $data);

$this->db->update('users', array('password' => $post['password']));
$success = $this->db->affected_rows();
if(!$success){
error_log('Unable to updatePassword('.$post['user_id'].')');
return false;
}
return true;
}
}
I'm passing $message variable to see if token works. Also while people are registering they have to input their email address. So I want tokens to go directly to emails they input in register form.
Thank you for help.

Configure your localhost mail settings as well
XAMPP
WAMP
Try This
$this->load->library('email');
$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'ssl://smtp.gmail.com',
'smtp_port' => 465,
'smtp_user' => 'mymail#gmail.com',
'smtp_pass' => 'pass',
'mailtype' => 'html',
'charset' => 'utf-8'
);
$this->email->initialize($config);
$this->email->set_newline("\r\n");
$clean = $this->security->xss_clean($this->input->post(NULL, TRUE));
$id = $this->user_model->insertUser($clean);
$token = $this->user_model->insertToken($id);
$qstring = base64_encode($token);
$url = site_url() . '/main/complete/token/' . $qstring;
$link = 'Activation Link';
$message = '';
$message .= '<strong>Dziekujemy za dokonanie rejestracji.</strong><br>';
$message .= '<strong>Aby dokończyć rejestrację przejdź na podany adres:</strong> '. $link;
$toEmail = $this->input->post('email');
$to = $toEmail; # undefine
$this->email->clear();
$this->email->from('whatever#c.com');
$this->email->to($to);
$this->email->subject('Thanks for registering');
$this->email->message($message);
if(!$this->email->send())
{
echo "fail <br>";
echo $this->email->print_debugger();
/*$this->session->set_flashdata('flash_message', 'Password reset fail.');
redirect(site_url().'/main/register');*/
}
else
{
echo "Pass <br>";
/* $this->session->set_flashdata('flash_message', 'Password reset done.');
redirect(site_url().'/main/login');*/
}

Since I don't see you attempting to send an email anywhere, this is how you send an email using CI's built in library.
//load ci email library
public function send_registration_email()
{
$this->load->library('email');
$link = '' . $url . '';
$message = $link;
$to = 'some#email.com';
$this->email->clear();
$this->email->from('whatever#c.com');
$this->email->to($to);
$this->email->subject('Thanks for registering');
$this->email->message($message);
if($this->email->send() === TRUE){ //Sends a plain text email containing the link
//something
}else{
//something else
}
}
