Weird error on sending SMTP mail using ZF mail 2.2.4

Question

Using this code :

include('vendor/autoload.php');

use Zend\Mail\Message;
use Zend\Mail\Transport\Smtp as SmtpTransport;
use Zend\Mail\Transport\SmtpOptions;

$message = new Message();
$message->addTo('email to')
        ->addFrom('email from')
        ->setSubject('Greetings and Salutations!')
        ->setBody("Sorry, I'm going to be late today!");


$transport = new SmtpTransport();
$options   = new SmtpOptions(array(
    'name'              => 'gmail.com',
    'host'              => 'smtp.gmail.com',
    'port'              => 465, // Notice port change for TLS is 587
    'connection_class'  => 'smtp',
    'connection_config' => array(
        'username' => 'email from',
        'password' => 'pass',
        'ssl'      => 'tls'
    ),
));
$transport->setOptions($options);
$transport->send($message);

I got this error:

Fatal error: Class 'Zend\Validator\ValidatorChain' not found in PHP\vendor\zendframework\zend-mail\Zend\Mail\Protocol\AbstractProtocol.php on line 97

I tried every example from documentation but none of them work and I got same error for all. I thought it is because I am testing it locally but it won't work when I upload it on server. I am testing this on wamp. Does anyone know what cause this error and how to fix it?

Answer 1

If you require zendframework/zend-mail via composer, there is a suggestion for zendframework/zend-validator. The validator is required if you want to send any emails.

So update your composer.json, add zend-validator as package and run composer update. This will load the Validator component so you can run your code.
