Mailing files?

Hi all,

I can't figure out why this script to mail a file to someone won't work:

function mail_attached($to, $from, $subject, $message, $filenames, $headers = '') { $unique_sep = md5(uniqid(time())); // Set up the top headers $headers .= "From: $from\n"; $headers .= "MIME-Version: 1.0\nContent-Type: multipart/mixed;boundary=\"$unique_sep\";\n"; $headers .= "charset=\"iso-8859-1\"\nContent-Transfer-Encoding:7bit\n\n"; $headers .= "If you are reading this, then your e-mail client does not support MIME.\n"; $headers .= "Sent with mail_attached() (c) 2002 John Coggeshall\n\n"; $headers .= "--$unique_sep\n"; // Include the text portion of the e-mail $headers .= "Content-Type: text/plain; charset=\"iso-8859-1\"\n"; $headers .= "Content-Transfer-Encoding: 7bit\n\n"; $headers .= $message . "\n\n"; // Now the attachment foreach($filenames as $val) { if($val['error'] != 4 && file_exists($val['tmp_name'])) { $headers .= "--$unique_sep\n"; $headers .= "Content-Type: {$val['type']}; name=\"{$val['name']}\"\n"; $headers .= "Content-Transfer-Encoding: base64\n"; $headers .= "Content-Disposition: attachment\n\n"; $linesz= $val['size']+1; $fp= fopen($val['tmp_name'], 'rb'); $headers .= chunk_split(base64_encode(fread($fp,$linesz))); } } $headers .= "--$unique_sep--\n"; if(!mail($to, $subject, $message, $headers)) return false; else return true; } /* End of mail_attached() function */ ?> $mail_to = "email@email.com"; $message = "Dear Karin, Here are the files that go with " . $_POST['first_name'] . " " . $_POST['last_name'] . "'s mentor application. Enjoy! Jess"; $result2 = mail_attached($mail_to,$webmaster_email,"Mentor Application Files",$message,$_FILES);

I didn't write the mail_attached function (my predecessor took it from a script site, I think) and I can't say I understand every line of it. If there are any alternatives, that would be awesome, or if you can see the problem with this, that would be cool too!

edit: A mail is received by the $mail_to user, message in tact, but no file attachment.

Thanks!
