PDF attachment error with wp_mail

I'm using wp_mail to send a PDF attachment through. However, every time I send the file it says there's an error or it corrupt when I download the attachment. Also, I'm trying to include a message with the attachment, but that isn't working either.

$upload_type is always equal to application/pdf

Am I missing and \r\n\?

<?php
// get file info
$upload_name=$_FILES["uploaded_file"]["name"];
$upload_type=$_FILES["uploaded_file"]["type"];
$upload_size=$_FILES["uploaded_file"]["size"];
$upload_temp=$_FILES["uploaded_file"]["tmp_name"];

$fp = fopen($upload_temp, "rb");
$file = fread($fp, $upload_size);

$file = chunk_split(base64_encode($file));
$num = md5(time());

//Normal headers

$headers = 'Reply-To: '. $_POST["email"] . "\r\n";
$headers .= 'Bcc: miket@wastewiseproducts.com' . "\r\n";
$headers  .= "From: info@wastewiseproducts.com\r\n";
$headers  .= "MIME-Version: 1.0\r\n";
$headers  .= "Content-Type: multipart/mixed; ";
$headers  .= "boundary=".$num."\r\n";
$headers  .= "--{$num}\r\n";

// This two steps to help avoid spam

$headers .= "Message-ID: <".gettimeofday()." TheSystem@".$_SERVER['SERVER_NAME'].">\r\n";
$headers .= "X-Mailer: PHP v".phpversion()."\r\n";

// With message

$headers .= "Content-Type: text/html; charset=iso-8859-1\r\n";
$headers .= "Content-Transfer-Encoding: 8bit\r\n";
$headers .= "".$message."\r\n";
$headers .= "--".$num."\r\n";

// Attachment headers

$headers  .= "Content-Type: ".$upload_type." ";
$headers  .= "name=\"".$upload_name."\"r\n";
$headers  .= "Content-Transfer-Encoding: base64\r\n";
$headers  .= "Content-Disposition: attachment; ";
$headers  .= "filename=\"".$upload_name."\"\r\n";
$headers  .= "".$file."\r\n";
$headers  .= "--".$num."--";

$message = "test";

if (wp_mail($to, $subject, $message, $headers)){
  echo "sent";
} else{
  echo "fail";
?>

I might recommend a slightly different approach.  Instead of sending the file, store the file on your server and send a link to the file.  Here's my thinking:

1. You can debug the PDF file creation and storage separately from the mail process
2. People who read email on handheld devices may not want to get printable attachments in the mail
3. You email traffic will be much "lighter" if you send a link instead of the entire document

Also, for security purposes, I would never use fopen() on an element of $_FILES.  There are way of testing for upload success, file integrity, etc.  These tests can help guard against attacks.  Maybe someone else can help with the "WordPress Way" of doing these things, but I can show you the PHP theory and practice of uploading a file in this code snippet.  The uploaded file is stored on the server and the browser presents a link to the client.

Hi Ray,
It may come to that. I was hoping to use the temp directory so its gone as soon as the session is done. I have had some success today with a template in code canyon. However, jquery accept: "application/pdf" is breaking the jquery validate plugin.
