How to send Email confirmation link via smtp Cakephp - email

Question

I am working in cakephp and want to send confirmation link on user signup but i do not know much about SMTP.
Here is What i have written I am using Token to confirm email which will expire next time if user hit the same confirmation link.
Here is usercontroller/signup method:
public function signup()
{
$this->layout = 'main';
if ($this->request->is('post')) {
$this->User->create();
$this->request->data['User']['password'] = AuthComponent::password($this->request->data['User']['password']);
$hash = sha1($this->request->data['User']['username'] . rand(0, 100));
$this->request->data['User']['tokenhash'] = $hash;
if ($this->User->validates()) {
$this->User->save($this->request->data);
$ms = 'Click on the link below to complete registration ';
$ms .= 'http://localhost/FindTutor/users/verify/t:' . $hash . '/n:' . $this->data['User']['username'] . '';
$ms = wordwrap($ms, 70);
$this->Email->from = 'usman.jamil0308#gmail.com';
$this->Email->to = $this->request->data['User']['email'];
$this->Email->subject = 'Confirm Registration..';
$this->Email->send($ms);
$this->Session->setFlash('Please Check your email for validation Link');
$this->redirect('/users/login');
}
}
}
Here is users/verify method to confirm if user hit the confirmation link.
public function verify(){
//check if the token is valid
if (!empty($this->passedArgs['n']) && !empty($this->passedArgs['t'])){
$name = $this->passedArgs['n'];
$tokenhash = $this->passedArgs['t'];
$results = $this->User->findByUsername($name);
if ($results['User']['activate']==0){
//check the token
if($results['User']['tokenhash']==$tokenhash)
{
$results['User']['activate']=1;
//Save the data
$this->User->save($results);
$this->Session->setFlash('Your registration is complete');
$this->redirect('/users/login');
exit;
}
else{
$this->Session->setFlash('Your registration failed please try again');
$this->redirect('/users/register');
}
}
else {
$this->Session->setFlash('Token has alredy been used');
$this->redirect('/users/register');
}
}else
{
$this->Session->setFlash('Token corrupted. Please re-register');
$this->redirect('/users/register');
}
}
Error is somthing like this:
mail(): Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()

Answer 1

try to use mailjet and configure your sever (wamp or xampp)the directorie sendmail and configure your app.php like that
'EmailTransport' => [
'default' => [
'className' => 'Mail',
// The following keys are used in SMTP transports
'host' => 'localhost',
'port' => 25,
'timeout' => 30,
'username' => '',
'password' => '',
'client' => null,
'tls' => null,
],
'mailjet' => [
'className' => 'smtp',
// The following keys are used in SMTP transports
'host' => 'in-v3.mailjet.com',
'username' => 'copy that from your account mailjet',
'password' => 'copy that from your account mailjet',
'port' => 587,
'timeout' => 3000,
'client' => null,
'tls' => null,
],
],
'Email' => [
'default' => [
'transport' => 'mailjet',
'from' => 'xxxxxx#gmail.com',
//'charset' => 'utf-8',
//'headerCharset' => 'utf-8',
],
],

public $smtp = array(
'host' => 'ssl://smtp.gmail.com',
'port' => 465,
'username' => 'your email id',
'password' => 'your password',
'transport' => 'Smtp',
);
App::uses('CakeEmail', 'Network/Email');
$Email = new CakeEmail('smtp');
$Email->from('info#email.com');
$Email->to($email);
$message = "hello";
$Email->send($message);

Answer 3

First Include Email Component in your App Controller like this :
public $components = array(
'Email'
);
Create a sendMail function in your App controller like this
public function _sendMail( $to, $from, $replyTo, $subject, $element,$parsingParams = array(),$attachments ="", $sendAs = 'html', $bcc = array()){
$port = '';
$timeout = '';
$host = '';
$username = '';
$password = '';
$client = '';
$toAraay = array();
if (!is_array($to)) {
$toAraay[] = $to;
} else {
$toAraay = $to;
}
$this->Email->smtpOptions = array(
'port' => "$port",
'timeout' => "$timeout",
'host' => "$host",
'username' => "$username",
'password' => "$password",
'client' => "$client"
);
$this->Email->delivery = 'smtp';
foreach ($parsingParams as $key => $value) {
$this->set($key, $value);
}
foreach ($toAraay as $email) {
$this->Email->to = $email;
$this->Email->subject = $subject;
$this->Email->replyTo = $replyTo;
$this->Email->from = $from;
if(!empty($bcc)){
$this->Email->cc = $bcc[0];
}
if ($attachments!="") {
$this->Email->attachments = array();
$this->Email->attachments[0] = $attachments ;
}
$this->Email->template = $element;
$this->Email->sendAs = $sendAs;
$this->Email->send();
$this->Email->reset();
}
}
Create a sendmail.ctp file in View/Emails/html
Add this content in file and also add your header or footer
<?php echo $message; ?>
Now whenever you want to send email call this function like this :
$this->_sendMail($to, $from, $replyTo, $subject, 'sendmail', array('message' => $message), "", 'html', $bcc = array());
Now you can implement your logic for verification email like this :
$message = 'Click on the link below to complete registration ';
$message .= 'http://localhost/FindTutor/users/verify/t:' . $hash . '/n:' . $this->data['User']['username'] . '';
$from = 'usman.jamil0308#gmail.com';
$to = $this->request->data['User']['email'];
$subject = 'Confirm Registration..';
$replyTo = 'usman.jamil0308#gmail.com';
$this->_sendMail($to, $from, $replyTo, $subject, 'sendmail', array('message' => $message), "", 'html', $bcc = array());
