PHP Question

How to download a file then redirect to another page in php?

Okay, I have the following php file:

<?php
header("Content-Type: application/octet-stream");

$file = $_GET["file"];
header("Content-Disposition: attachment; filename=" . urlencode($file));
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Description: File Transfer");
header("Content-Length: " . filesize($file));
$file = "pdf/".$file;
flush(); // this doesn't really matter.
$fp = fopen($file, "r");
while (!feof($fp)) {
echo fread($fp, 65536);
flush(); // this is essential for large downloads
}

if ($file="pdf/sampleFile.pdf") {
?>
<html>
<head>
<title>Best Recipes Ever!</title>
<link rel="stylesheet" href="style/style.css" />
</head>

<body>
<div id="header">
<h1>Best Recipes Ever!</h1>
</div>
<div id="page">
<h1>Thank You For Your Download!</h1>
<p>I sincerely hope that you enjoy this free recipe! If satisfied, please feel free to return and purchase some of my recipes. Trust me, you won't regret it!</p>
</div>
</body>
</html>
<?php
}

fclose($fp);
?>


The idea is, if its the sample file, it downloads the file then redirects to a thank you page. However, if its a paid-for download(s), this file only downloads the files, but does nothing (because the page they are coming from is a list of purchased download file links, so it needs to stay on that page).

What this page is doing, however, is downloading the file but doesn't redirect. What am I doing wrong? And how can I fix it?

Answer

Best bet is to turn your page order around a little bit. Set up a page that's a "thank you for downloading this sample" page, and have it set up to do a javascript refresh that actually takes you to the download. As it's a download, not a new page, the thank you page will still be there. In case they don't have javascript on the browser, put a link to the actual file.

You could have a page for each file, but best bet would be to pass the filename in as a get var, i.e. ThankYou.php?file=sample.pdf
