Hello all,

Im using this mail function
Code:
<?php
// Read POST request params into global vars
$to      = "chapters@letstrywriting.com";
$from    = "Submission@letstrywriting.com";
$name    = "Submission";
$subject = $_POST['subject'];
$message = "";

$your_name = $_POST['name'];
$your_email = $_POST['subject'];
$your_phone = $_POST['message']; 

if (!empty($your_name)) { 
$message .= 'Your Name: '. $your_name ."\n\n";
} 

if (!empty($your_name)) { 
$message .= 'Your Email: '. $your_email ."\n\n";
} 

if (!empty($your_name)) { 
$message .= 'Your Phone: '. $your_phone ."\n\n";
} 

// Obtain file upload vars
$fileatt		= $_FILES['fileatt']['tmp_name'];
$fileatt_type	= $_FILES['fileatt']['type'];
$fileatt_name	= $_FILES['fileatt']['name'];

$headers = "From: $from";

if (is_uploaded_file($fileatt) || is_uploaded_file($fileatt2) || is_uploaded_file($fileatt3)) {
  // Read the file to be attached ('rb' = read binary)
  if (is_uploaded_file($fileatt)) {
  	$file = fopen($fileatt,'rb');
  	$data = fread($file,filesize($fileatt));
  	fclose($file);

  	// Base64 encode the file data
  	$data = chunk_split(base64_encode($data));
  }

  // Generate a boundary string
  $semi_rand = md5(time());
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
  
  // 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/plain;\n charset=\"iso-8859-1\"\n" .
             "Content-Transfer-Encoding: 7bit\n\n" .
             $message . "\n\n" .
			 "--{$mime_boundary}\n";

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

// Send the message
$ok = @mail($to, $subject, $message, $headers);
if ($ok) {
  echo "<p>Mail sent!</p>";
  header("location: subthanks.php");
} else {
  echo "<p>Mail could not be sent. Sorry!</p>";
  header("location: subbad.php");
}
?>
It seems to work, however when I go to check the email the file has not attached. The attachment seems to be there but it gives its size as 0kb and doesnt register it with a .filename ending. Could someone show me where im going wrong?

Thanks in advance.
