PDF attachment error with wp_mail

m2ew asked
Last Modified: 2016-05-28
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\?

// get file info

$fp = fopen($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";
