Using the send() Method

The send() method of the Swift_Mailer class sends a message using exactly the same logic as your Desktop mail client would use. Just pass it a Messgae and get a result.

To send a Message with send():

  1. Create a Transport from one of the provided Transports – Swift_SmtpTransport, Swift_SendmailTransport, Swift_MailTransport or one of the aggregate Transports.
  2. Create an instance of the Swift_Mailer class, using the Transport as it's constructor parameter.
  3. Create a Message according to the instructions laid out in Creating Messages
  4. Send the message via the send() method on the Mailer object.

The message will be sent just like it would be sent if you used your mail client. An integer is returned which includes the number of successful recipients. If none of the recipients could be sent to then zero will be returned, which equates to a boolean false. If you set two To: recipients and three Bcc: recipients in the message and all of the recipients are delivered to successfully then the value 5 will be returned.

Note: In the following example, one is email is sent to both receiver@domain.org and other@domain.org. Both addresses will be visible in the To: header. If you don't want receiver@domain.org and other@domain.org to know about each other you should use batchSend() instead. 
<?php

require_once 'lib/swift_required.php';

//Create the Transport
$transport = Swift_SmtpTransport::newInstance('localhost', 25);

//Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);

//Create a message
$message = Swift_Message::newInstance('Wonderful Subject')
  ->setFrom(array('john@doe.com' => 'John Doe'))
  ->setTo(array('receiver@domain.org', 'other@domain.org' => 'A name'))
  ->setBody('Here is the message itself')
  ;
  
//Send the message
$numSent = $mailer->send($message);

printf("Sent %d messages\n", $numSent);

/* Note that often that only the boolean equivalent of the
   return value is of concern (zero indicates FALSE)
   
if ($mailer->send($message))
{
  echo "Sent\n";
}
else
{
  echo "Failed\n";
}
