Topic awaiting preservation: sending text attachments in php form (Page 1 of 1)

I have this form in php. everything was working fine until i added the piece of code for attachment of files through a form. eg. the user wants to attach a word doc.

After I m not receiving an email , i m not sure what seems to be the problem.
kindly help !
thanks in advance.

<?php include("connection.php");

// Read POST request params into global vars
$to= "mail@testmail.co.uk";
$subject= " Form " ;
$message.= "Content-Type: text/plain; charset=\"iso-8859-1\"\n";
$message.= "Content-Transfer-Encoding: 7bit\n";
$message.= "\n";
$message.="Title :\t$HTTP_POST_VARS[title]<br>";
$message.="Name :\t$HTTP_POST_VARS[name]<br>";
$message.="Date of Birth :\t$HTTP_POST_VARS[dob]<br>";
$message.="Country of Birth :\t$HTTP_POST_VARS[birthcountry]<br>";
$message.="Nationality:\t$HTTP_POST_VARS[nationality]<br>";


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

$headers = "From: ".$HTTP_POST_VARS['email'];

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

// 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; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\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";
}

// Send the message
mail($to, $subject, $message, $headers);
