mail() with zip file attachments

[mattspriggs28]

Hi,

 

I have a script that generates a password protected zip file, attaches to an email and sends.

 

The email is sent successfully and received. However, the zip file is not attached. The weird thing is that the size of the email implies that there is an attachment.

 

I've tried in a few different mail clients to see if it was my own that was blocking the zip attachment, but the others are exactly the same.

 

I've also tried generating the zip file without a password and attaching, but again with no luck.

 

Just to further explain, the file needs to be stored within a password protected zip as it will contain confidential information.

 

Here's my code:

 

// a random hash will be necessary to send mixed content
$separator = md5(time());
// carriage return type (we use a PHP end of line constant)
$eol = PHP_EOL;

$subject = $myForm['surveyType'] . ' : ' . REFERRAL_SUBJ;

// generate the zip file and attach
$password = REFERRAL_PWD;
$outfile = 'referral.zip';

// create file with body inside it
$refFile = time().".html";
$fh = fopen($refFile, 'w') or die("can't open file");
$refData = $smarty->fetch(REFERRAL_BODY_TPL);
fwrite($fh, $refData);
fclose($fh);	

system("zip -P $password $outfile $refFile");

// Read ZIP file into string
$zipDoc = file_get_contents($outfile);
$attachment = chunk_split(base64_encode($zipDoc));

// main header (multipart mandatory)
$headers = "From: " . REFERRAL_MAIL_FROM . $eol;
$headers .= "Reply-To: " . REFERRAL_MAIL_REPLY . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol . $eol;
$headers .= "Content-Transfer-Encoding: 7bit" . $eol;
$headers .= "This is a MIME encoded message." . $eol . $eol;
// message
$headers .= "--" . $separator . $eol;
$headers .= "Content-Type: text/html; charset=\"iso-8859-1\"" . $eol;
$headers .= "Content-Transfer-Encoding: 8bit" . $eol . $eol;
$headers .= $body . $eol . $eol;
$headers .= "--" . $separator . "--" . $eol . $eol;
// attachment
$headers .= "--" . $separator . $eol;
$headers .= "Content-Type: application/zip; name=\"" . $outfile . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: base64" . $eol;
$headers .= "Content-Disposition: attachment; filename=\"" . $outfile . "\"" . '\r\n\r\n';
$headers .= $attachment . '\r\n\r\n';
$headers .= "--" . $separator . "--";
// send message

$res = mail(REFERRAL_EMAIL_ADDRESS, $subject, "", $headers);

unlink('referral.zip');
unlink($refFile);

 

Any help is much appreciated.

Managed to sort it. It was a case of simply swapping the message and attachment code blocks around, and all works fine!
