Trouble with mail() & attachments

[jjfletch]

I'm having a very frustrating time trying to figure out what keeps going wrong with this code. I just want the form to be able to mail an attachment, but no matter what, I keep getting the "Undefined index:filename" error.

I've tried setting the error reporting at different levels, but that doesn't seem to help. I'm convinced there's something wrong with the code.

Can someone help me out here? I'll post the relevant code below.

	if ($nm && $sp1 && $add && $e && $ph) {

$sendTo = "[e-mail]";
$subject = "Registration";

$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";
$tmp_name = $_FILES['filename']['tmp_name'];
$type = $_FILES['filename']['type'];
$name = $_FILES['filename']['name'];
$size = $_FILES['filename']['size'];
$message = "Logo file included: $name";

if (file_exists($tmp_name)){
	if(is_uploaded_file($tmp_name)){
        $file = fopen($tmp_name,'rb');
        $data = fread($file,filesize($tmp_name));
        fclose($file);
        $data = chunk_split(base64_encode($data));
     }	


$headers = "From: " . $_POST["first_name"] ." " . $_POST["last_name"] ."<" . $_POST["email"] . ">\r\n";
$headers .= "Cc: " . $_POST["email"] . "\r\n";
$headers .= "Bcc: [e-mail]" . "\r\n";
$headers .= "Reply-To: " . $_POST["email"] . "\r\n";
$headers .= "Return-path: " . $_POST["email"]; 
$headers .= "MIME-Version: 1.0\r\n" . "Content-Type: multipart/mixed;\r\n" . " boundary=\"{$mime_boundary}\"";

$message = "

Sponsorship Type:		$sp1

if (strlen($spt1) > 0) { $message .= "$spt1"; }
if (strlen($sp_amt) > 0) { $message .= "$sp_amt"; }
if (strlen($spt2) > 0) { $message .= "$spt2"; }
if (strlen($spt3) > 0) { $message .= "$spt3"; }
if (strlen($spt4) > 0) { $message .= "$spt4"; }
if (strlen($spt5) > 0) { $message .= "$spt5"; }
if (strlen($spt6) > 0) { $message .= "$spt6"; }
if (strlen($spt7) > 0) { $message .= "$spt7"; }
if (strlen($spt8) > 0) { $message .= "$spt8"; }
if (strlen($spt9) > 0) { $message .= "$spt9"; }
if (strlen($spt10) > 0) { $message .= "$spt10"; }
if (strlen($spt11) > 0) { $message .= "$spt11"; }
if (strlen($spt12) > 0) { $message .= "$spt12"; }
if (strlen($spt13) > 0) { $message .= "$spt13"; }

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

  	$message .= "--{$mime_boundary}\n" .
     "Content-Type: {$type};\n" .
     " name=\"{$name}\"\n" .
     //"Content-Disposition: attachment;\n" .
     //" filename=\"{$fileatt_name}\"\n" .
     "Content-Transfer-Encoding: base64\n\n" .
     $data . "\n\n" .
     "--{$mime_boundary}--\n";

mail($sendTo, $subject, $message, $headers); 
echo '<?php include ("spform.html"); ?> <p>Your sponsor form has been successfully submitted.  An email has been sent to you confirming the information.</p>';
}	
	} else {
	echo '<p><font color="red">Form could not be processed due to a system error</font></p>';
}


} else {

?>

So have you verified that your form is using the correct encoding, and that the file upload field is called "filename", and have you checked that a file was submitted with the form before trying to use it? (If you have, I'm guessing that's what $nm, $sp1, $add, $e, and $ph mean. Why such opaque variable names?)
