PHP5 - Mail with attachment problems
Expert: Robert Davis - 11/2/2009
Question
Hi. Can you help me with a bit of code for the mail function? My problem is that I can't seem to attach files correctly. Here is part of the code: $to="";
$from="R.-SM";
$subject="Cerere site";
$message="Nume: $_POST[nume]";
$headers="From: $from";
$semi_rand=md5(time());
$mime_boundary="==Multipart_Boundary_x{$semi_rand}x";
$headers.="\r\nMIME-Version: 1.0\r\n"."Content-Type: multipart/mixed;\r\n"."boundary=\"$mime_boundary\"";
$message=\"$mime_boundary\"\r\n"."Content-Type: text/plain; charser=\"iso-8859-1\"\r\n"."Content-Transfer-Encoding: 7bit\r\n\r\n".$message."\r\n\r\n";
$message.="--\"$mime_boundary\"\r\n";
$data=chunk_split(base64_encode(file_get_contents("site".$timp.".zip")));
$message.="Content-Type: application/octet-stream;\r\n"."name=\"site".$timp.".zip\"\r\n"."Content-Disposition: attachment;\r\n"."filename=\"site".$timp.".zip\"\r\n"."Content-Transfer-Encoding: base64\r\n\r\n".$data."\r\n\r\n";
$message.="--\"$mime_boundary\"\r\n";
(mail($to, $subject, $message, $headers)
More specifically, my problem is: the original attachment is sent as part of the message (is sent as text) and the entire message is sent as an attachment. I think it has something to do with the boundaries not being set properly, but I can't seem to figure out what the problem is. Any help will be very much appreciated. Bye.
Answer
Here's part of a mail function I've used successfully in the past, when I compare it to yours it looks like there should be more than one boundary when an attachment is involved:
// Construct the message
$headers.= "MIME-Version: 1.0\n";
if ($attachments){
$headers.= "Content-Type: multipart/mixed;\n\tboundary=\"----=_NextPart_000_THE_1ST_B0UNDARY\"\n";
} else {
$headers.= "Content-Type: multipart/alternative;\n\tboundary=\"----=_NextPart_000_THE_1ST_B0UNDARY\"\n";
}
$headers.= "X-Priority: $priority\n";
$headers.= "X-Mailer: 1 2 Mime Mail v0.3\n";
$headers.= "\n";
$headers.= "This is a multi-part message in MIME format.\n";
$headers.= "\n";
$headers.= "------=_NextPart_000_THE_1ST_B0UNDARY\n";
if ($attachments){
$headers.= "Content-Type: multipart/alternative;\n\tboundary=\"----=_NextPart_001_THE_2ND_B0UNDARY\"\n";
$headers.= "\n";
$headers.= "------=_NextPart_001_THE_2ND_B0UNDARY\n";
}
$headers.= "Content-Transfer-Encoding: quoted-printable\n";
$headers.= "\n";
$headers.= wordwrap($text,76)."\n";
if ($attachments){
$headers.= "------=_NextPart_001_THE_2ND_B0UNDARY\n";
} else {
$headers.= "------=_NextPart_000_THE_1ST_B0UNDARY\n";
}
$headers.= "Content-Type: text/html;\n\tcharset=\"iso-8859-1\"\n";
$headers.= "Content-Transfer-Encoding: base64\n\n";
$headers.= "\n";
$headers.= chunk_split(base64_encode($html))."\n";
$headers.= "\n";
// Attach the attachments to this mail
if($attachments){
$headers.= "------=_NextPart_001_THE_2ND_B0UNDARY--\n";
$headers.= "\n";
$attachments = is_array($attachments) ? $attachments : array($attachments);
foreach($attachments as $atm){
if (file_exists($atm)){
$atmname = basename($atm);
$afd= fopen ($atm, "r");
$atmcontent = fread($afd,filesize($atm));
fclose ($afd);
$headers.= "------=_NextPart_000_THE_1ST_B0UNDARY\n";
$headers.= "Content-Type: application/octetstream;\n\tname=\"$atmname\"\n";
$headers.= "Content-Transfer-Encoding: base64\n";
$headers.= "Content-Disposition: attachment;\n\tfilename=\"$atmname\"\n";
$headers.= "\n";
$headers.= chunk_split(base64_encode($atmcontent))."\n";
}
}
}
// End of the message
$headers.= "------=_NextPart_000_THE_1ST_B0UNDARY--\n";
// Actually send the mail
if (mail($to,$subject,"",$headers,"-f $from")) {
//echo "mail sent";
return true;
} else {
//echo "mail not sent";
return false;
}
