Attaching a pdf file

[NoBullMan]

Hi all,
can you tell me what the headers would be for attaching a pdf file to an email?
I have:

  $mail_to = "[e-mail]";
  $mail_subject = "Discussion Meetings";
  $headers  = "MIME-Version: 1.0\r\n"; 
  $headers .= "Content-type:text/html;charset=iso-8859-1\r\n";
  $headers .= "From: ScienceGuy@some_domain.com";
  $headers .= "\r\n";
  $mail_body = "....";
mail($mail_to, $mail_subject, $mail_body, $headers);

Thanks a lot.

Well...I found this script from one of the posts and it seems like it does part of the job. I get to attach the file and send it, but damaged! A 57K file arrives at 4K.
If someone could tell me what the file arrives corrupted, I greatly appreciate it.

  $fileatt = "assets/docs/"; // Location of file on server
  $fileatt_type = "application/pdf";// Type of file being sent
  $fileatt_name = "attachment.pdf";// Name of file
  $fileatt_path = $fileatt.$fileatt_name;// Name of file

  // If the file exists...
  if (file_exists($fileatt_path)) 
  {
    // Read the file to be attached ('rb' = read binary)
    $file = fopen($fileatt_path,'rb');
    $data = fread($file,filesize($fileatt));
    fclose($file);

// Generate a boundary string
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers .= "From: my_name@some_domain.com";
// Add the headers for a file attachment
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
// Add a multipart boundary above the plain message
$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type: text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n";
$message .="This is an automated email sent from a php script\n";

// Base64 encode the file data
$data = chunk_split(base64_encode($data));
// Add file attachment to the message
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n";
  $mail_to = "[e-mail]";
  $mail_subject = "Test email from";

  if (!mail($mail_to, $mail_subject, $message, $headers))
      echo "Mail send failed!";
	else
	  echo "Mail sent successfully to $mail_to";
}

I think it's because you're using filesize() on the directory containing the file, not the file itself 😉

Thanks a lot. That WAS the problem!
I have one more question:
In the following piece of code:

$message = "This is a multi-part message in MIME format.\n\n" .
    "--{$mime_boundary}\n" .
    "Content-Type: text/html; charset=\"iso-8859-1\"\n" .
    "Content-Transfer-Encoding: 7bit\n\n" .
    $message . "\n\n";
    $message .="This is an automated email sent from a php script\n";

// Base64 encode the file data
$data = chunk_split(base64_encode($data));
// Add file attachment to the message
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n"; 

if I leave the message "This is an automated email sent from a PHP script" as is, then I get the email with the attachment "attaced", but I can't get the line breaks to work. However, if I put any html tags in the message, to ensure proper line breaks, then the attachment gets "included" and not attached.
Is there a way to get around this?
