Php and dompdf

hello,
I have a code to send my form with dompdf to a pdf file. Everything works except the php result. I can't display the php result of $total on my pdf.. Hope someone can help me!! You can find my code if you follow the link





<?php
if (!empty($_POST)) {

// Used for later to determine result
$success = $error = false;

// Object syntax looks better and is easier to use than arrays to me
$post = new stdClass;

// Usually there would be much more validation and filtering, but this
// will work for now.
foreach ($_POST as $key => $val)
$post->$key = trim(strip_tags($_POST[$key]));

// Check for blank fields
if (empty($post->name) OR empty($post->email))
$error = true;

else {

// 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.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 contents of the HTML email into a variable for later
ob_start();
require_once($dir.'/html.php');
$html_message = ob_get_contents();
ob_end_clean();

// Load the SwiftMailer files
require_once($dir.'/swift/swift_required.php');

$mailer = new Swift_Mailer(new Swift_MailTransport()); // Create new instance of SwiftMailer

$message = Swift_Message::newInstance()
->setSubject('How To Create and Send An HTML Email w/ a PDF Attachment') // Message subject
->setTo(array($post->email => $post->name)) // Array of people to send to
->setFrom(array('[email protected]' => 'Nettuts+')) // From:
->setBody($html_message, 'text/html') // Attach that HTML message from earlier
->attach(Swift_Attachment::newInstance($pdf_content, 'nettuts.pdf', 'application/pdf')); // Attach the generated PDF from earlier

// Send the email, and show user message
if ($mailer->send($message))
$success = true;
else
$error = true;
