Question

I have a php script that limits the amount of times people can download content on my site. I found this script by google searching and changed it a bit to get it working for me.

The problem is I don’t know anything really about php. The first part of the script checks the referring page. When I copied the php script, it was set up to check a single URL. My problem is I want to reference the php script from multiple pages, because one page has flash on it, and another page I created for mobile phones that don’t have flash. Because of this, the link only works on one page – the page with the url I replace in the script.

My question is, what is the code to include multiple URLs in the reference check? I don’t know if it’s something very simple, or if it’s even possible.

Below is the part of the php script which checks the referring URL, and then proceeds to login to mySQL DB to begin the download.

$referer = $_SERVER['HTTP_REFERER'];

$keymatch= $_SESSION['key'];
$pass='key';
$md5value= md5($pass);

if (($referer=="my url containing php script link")&& ($keymatch==$md5value)) {

$username = "user";
$password = "password";
$hostname = "host";
$database = "database";
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
$selected = mysql_select_db($database,$dbhandle)
or die("Could not select $database");

Thanks in advance for any help.

Rather than checking referer matches on one link:

if (($referer=="my url containing php script link")...

Create an array of links and match against that:

$referers = array('link1', 'link2','link3');
if((in_array($referer, $referers)...
