PDF Download and PHP

Leviathan2003

Need some help with the following code....

Currently, it will open the PDF in the browser window after I have a user enter a valid email address. Now I need to have this file to be forced to be downloaded to the client, instead of lauching in the browser. Can someone help me?

<HTML>
<HEAD>
<TITLE>PDF Download</TITLE>
<script type="text/javascript" language="JavaScript">
pos = navigator.appVersion.indexOf("MSIE 6");
if (pos != -1)
{
document.write ('<META HTTP-EQUIV=refresh CONTENT="3; URL=file.pdf" target="new">');
}
else
{
document.write ('<META HTTP-EQUIV=refresh CONTENT="3; URL=file.pdf" target="new">');
}
</script>

</HEAD>
<BODY>
<CENTER>

<?php

/ Email Address from Form /
$emailFromForm = strtolower($_POST['Email']) ;

/ Remote Address /
$ip = strtolower($_SERVER['REMOTE_ADDR']);

/ Remote Host /
$host = strtolower(gethostbyaddr($_SERVER['REMOTE_ADDR']));

/ recipients /
$to = "user@host.com";

/ subject /
$subject = "PDF Document downloaded from website";

/ date /
$dldate = date ("l dS of F Y h:i:s A");

/ message /
$message = "
<html>
<head>
<title>PDF Downloaded</title>
</head>
<body>

The PDF was downloaded from the Website. Details are as follows: 
 
<table border=\"0\">
<tr>
<td>Email:</td>
<td></td>
<td>$emailFromForm</td>
</tr>
<tr>
<td>Host:</td>
<td></td>
<td>$host</td>
</tr>
<tr>
<td>IP Address:</td>
<td></td>
<td>$ip</td>
</tr>
<tr>
<td>Date/Time:</td>
<td></td>
<td>$dldate</td>
</tr>
</table>


</body>
</html>
";

/ To send HTML mail, you can set the Content-type header. /
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";

/ additional headers /
$headers .= "From: Web Site <wesbite@host.com>\r\n";

/ and now mail it /
mail($to, $subject, $message, $headers);

if(isset($_POST['Submit'])) {
echo "Thank you! Please wait while you are redirected to the PDF\n";
} else {
echo "You must enter an email address.\n";
}

You don't need the javascript. Rather, use php's header() function to determine what the browser does with the file.

A suggestion: rather than have the

if(isset($_POST['Submit'])) {

at the end of the script, I would make it one of the very first things, and then have your default output be the very last thing in the script...

i.e.
1. init and filter variables
2. take action based on submissions
3. default output

The reason for this is that you want to do all your logic BEFORE you ouput anything. Without using templates, that's not always possible; but the principle holds.

if(isset($_POST['Submit'])) { 
	header("Content-type: application/octet-stream"); 
	header("Content-Disposition: attachment; filename=$filename.$ext"); 
	header("Content-Transfer-Encoding: binary");
         print $your_content_to_download;
         die;

}

//  print default html under here

Note that header() MUST come before any other output!

Taking this a step further... is there any way to detect if the file was actually downloaded (vs cancelled)?

I need to do exactly this - trap info and send an email when a file is downloaded. But right now I send the email first, and can't see how to get any return code from the download.

Thanks.
