Cannot get Swiftmailer to work on a PHP site - php

Question

I am new to PHP and Swiftmailer.
What I am trying to do is set up a PHP site on a webserver and use SwiftMailer to send e-mails.
The code I got does work on my local XAMPP server, but will produce the error message:
"Fatal error: Class 'Swift_Attachment' not found in /[address to my php file]"
when executed from the on-line webserver.
Here is my code:
<?php
// Get this directory, to include other files from
$dir = dirname(__FILE__);
// Get the contents of the pdf into a variable for later
ob_start();
require_once($dir.'/pdf_selbst_lir.php');
$pdf_html = ob_get_contents();
ob_end_clean();
// Load the dompdf files
require_once($dir.'/dompdf/dompdf_config.inc.php');
$dompdf = new DOMPDF(); // Create new instance of dompdf
$dompdf->load_html($pdf_html); // Load the html
$dompdf->render(); // Parse the html, convert to PDF
$pdf_content = $dompdf->output(); // Put contents of pdf into variable for later
// Get the content of the HTML email into a variable for later
ob_start();
require_once($dir.'/Templates/html.php');
$html_message = ob_get_contents();
ob_end_clean();
// Swiftmailer
require_once($dir.'/swiftmailer-5.0.1/lib/swift_required.php');
// Create the attachment with your data
$attachment = Swift_Attachment::newInstance($pdf_content, 'pdfname.pdf', 'application/pdf');
// Create the Transport
$transport = Swift_SmtpTransport::newInstance('mymailserver', 587, 'tls')
->setUsername('username')
->setPassword('password')
;
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
// Create the message
$message = Swift_Message::newInstance()
->setFrom(array('senderaddress' => 'Sender Name'))
->setSubject('subject')
->addBcc('somebccaddress')
->setBody($html_message, 'text/html')
->attach($attachment);
try {
$message->addTo('somerecipient');
}
catch (Swift_RfcComplianceException $e)
{
// Address was invalid
echo "Email address not correct.";
}
// Send the message
if ($mailer->send($message))
$success = true;
else
$error = true;
?>
Note that when I comment out all the attachment-related stuff, the error message switches to
"Fatal error: Class 'Swift_SmtpTransport' not found in /[address to my php file]" and points to the "$transport" line.
So it appears the overall SwiftMailer is not working, and this is not attachment-related.
Help would be greatly appreciated!

Answer 1

I don'see ->setTo( your_mail_dest) and ->send()
try with a simple send like this
$message = Swift_Message::newInstance()
->setFrom(array('senderaddress' => 'Sender Name'))
->setTo( **** your_mail_dest ****)
->setSubject('subject')
->addBcc('somebccaddress')
->setBody($html_message, 'text/html')
->attach($attachment)
->send();

Case closed.
It turned out that the code was working fine after all. All I needed to do was upgrade Swiftmailer (now running on 5.4.2-DEV). Sorry for the hassle and thanks scaisEdge for helping!
