OK... thanks for everyone's help on sending an attachment via the mail() function. This is almost exactly how I want it to work.

My problem now is that it sends the attachment, but not a message in the body. I've been experimenting for a while with no results... can anyone shed some light? Here is the code...

<?php require_once("../application.php"); ini_set('error_reporting', E_ALL); ini_set('display_errors', 1); # File for Attachment $eol="\r\n"; $now="today"; $f_name="../PDF-Library/" . $_POST['f_name']; // use relative path OR ELSE big headaches. $letter is my file for attaching. $handle=fopen($f_name, 'rb'); $f_contents=fread($handle, filesize($f_name)); $f_contents=chunk_split(base64_encode($f_contents)); //Encode The Data For Transition using base64_encode(); $f_type=filetype($f_name); fclose($handle); # To Email Address $emailaddress=$_POST['custemail']; # Message Subject $emailsubject="Requested PDF from ".$_SESSION['firstname']." at MicroMain Corporation"; # Message Body ob_start(); require("emailbody.php"); // i made a simple & pretty page for showing in the email $body=ob_get_contents(); ob_end_clean(); # Common Headers $headers = 'From: me@mydomain.com>'.$eol; $headers .= 'Reply-To: me@mydomain.com>'.$eol; $headers .= 'Return-Path: me@mydomain.com>'.$eol; // these two to set reply address $headers .= "Message-ID: <".$now." TheSystem@".$_SERVER['SERVER_NAME'].">".$eol; $headers .= "X-Mailer: PHP v".phpversion().$eol; // These two to help avoid spam-filters # Boundry for marking the split & Multitype Headers $mime_boundary=md5(time()); $headers .= 'MIME-Version: 1.0'.$eol; $headers .= "Content-Type: multipart/mixed; boundary=\"".$mime_boundary."\"".$eol; $msg = "Content-Transfer-Encoding: 7bit".$eol; # Text Version $msg .= "--".$mime_boundary.$eol; $msg .= "Content-Type: text/plain; charset=iso-8859-1".$eol; $msg .= "Content-Transfer-Encoding: 7bit".$eol; $msg .= "Content-Disposition: inline".$eol; $msg .= "Thanks for your interest!".$eol.$eol; # Attachment $msg .= "--".$mime_boundary.$eol; $msg .= "Content-Type: application/pdf; name=\"".$_POST['f_name']."\"".$eol; // sometimes i have to send MS Word, use 'msword' instead of 'pdf' $msg .= "Content-Transfer-Encoding: base64".$eol; $msg .= "Content-Disposition: attachment; filename=\"".$_POST['f_name']."\"".$eol.$eol; // !! This line needs TWO end of lines !! IMPORTANT !! $msg .= $f_contents.$eol.$eol; # Finished $msg .= "--".$mime_boundary."--".$eol.$eol; // finish with two eol's for better security. see Injection. # SEND THE EMAIL mail($emailaddress, $emailsubject, $msg, $headers); print("email was sent"); exit(); ?>
