Single use download script - Modification [on hold]
- by Iulius
I have this Single use download script!
This contain 3 php files: page.php , generate.php and variables.php.
Page.php Code:
<?php
include("variables.php");
$key = trim($_SERVER['QUERY_STRING']);
$keys = file('keys/keys');
$match = false;
foreach($keys as &$one) {
if(rtrim($one)==$key) {
$match = true;
$one = '';
}
}
file_put_contents('keys/keys',$keys);
if($match !== false) {
$contenttype = CONTENT_TYPE;
$filename = SUGGESTED_FILENAME;
readfile(PROTECTED_DOWNLOAD);
exit;
} else {
?>
<html>
<head>
<meta http-equiv="refresh" content="1; url=http://docs.google.com/">
<title>Loading, please wait ...</title>
</head>
<body>
Loading, please wait ...
</body>
</html>
<?php
}
?>
Generate.php Code:
<?php
include("variables.php");
$password = trim($_SERVER['QUERY_STRING']);
if($password == ADMIN_PASSWORD) {
$new = uniqid('key',TRUE);
if(!is_dir('keys')) {
mkdir('keys');
$file = fopen('keys/.htaccess','w');
fwrite($file,"Order allow,deny\nDeny from all");
fclose($file);
}
$file = fopen('keys/keys','a');
fwrite($file,"{$new}\n");
fclose($file);
?>
<html>
<head>
<title>Page created</title>
<style>
nl {
font-family: monospace
}
</style>
</head>
<body>
<h1>Page key created</h1>
Your new single-use page link:<br>
<nl>
<?php
echo "http://" . $_SERVER['HTTP_HOST'] . DOWNLOAD_PATH . "?" . $new;
?></nl>
</body>
</html>
<?php
} else {
header("HTTP/1.0 404 Not Found");
}
?>
And the last one Variables.php Code:
<?
define('PROTECTED_DOWNLOAD','download.php');
define('DOWNLOAD_PATH','/.work/page.php');
define('SUGGESTED_FILENAME','download-doc.php');
define('ADMIN_PASSWORD','1234');
define('EXPIRATION_DATE', '+36 hours');
header("Cache-Control: no-cache, must-revalidate");
header("Expires: ".date('U', strtotime(EXPIRATION_DATE)));
?>
The http://www.site.com/generate.php?1234 will generate a unique link like page.php?key1234567890. This link page.php?key1234567890 will be sent by email to my user.
Now how can I generate a link like this page.php?key1234567890&[email protected] ? So I think I must access the generator page like this generate.php?1234&[email protected] .
P.S. This variable will be posted on the download page by "Hello, "
I tried everthing to complete this, and no luck.
Thanks in advance for help.
