Different includes for certein referrers

Hello!

I have a website about cosmetics where I want to offer specials for people who come to my website from specific sites.

I have found something like that:

<?php
$referrer = $_SERVER['HTTP_REFERER'];
if (preg_match("/specificwebsite.com/",$referrer)) {
      header('Location: http://www.mywebsite.com/1.html');
} else {
      header('Location: http://www.mywebsite.com/2.html');
};
?>

Code (markup):

But this is REDIRECTING and its only for one referrer (I have them over 20), I need something that INCLUDE files, is it possible with $_SERVER['HTTP_REFERER']?

Also it is possible to have these specific domains in external file like domains.txt so I do not have to edit every page on my website when I update that list?

Anyone know script that can do that?

Thank you for help,
Evelin

 

You could make use of http://php.net/manual/en/language.types.array.php and check if the domainname is in the $_SERVER['HTTP_REFERER'];

example:

<?php
$sites = array(
"www.yourwebsite.com" => "1.html",
"www.google.com" => "2.html",
"www.bing.com" => "3.html",
"www.mysite.org" => "4.html",
"tweakers.net" => "5.html",
"www.test.com" => "6.html"
);
 
foreach ($sites AS $key => $location)
{
    if (stripos($_SERVER['HTTP_REFERER'], $key) > 0)
    {
        header("Location: " . $location);
        exit;
    }
}
?>
 

PHP:

 

I have a script that should do what I want, it looks like this:

<?php
    $x=$_SERVER['HTTP_REFERER'];
    $x1=str_ireplace("http://","",$x);
    $t=file_get_contents("sites.txt");
    $arr=explode("\n",$t);
    if(!empty($x) && in_array($x1,$arr))
    {
        include("file1.php");
    }
?>

PHP:

Unfortunately when I added this to my website I got "Internal Server Error", anyone can tell me what is wrong with that code?

Thank you,

    $referer = str_ireplace('http://', '', $_SERVER['HTTP_REFERER']);
   
    $refListing = explode("\n",
                          file_get_contents('sites.txt'));
    if(in_array($x1, $arr))
    {
        include("file1.php");
    }

Code (markup):

better way is

to create a seperate PHP file with your list you want to use as referer check

<?php
/* array_referers.php */
 
$refererCheckArray = array( /* your list to all the 'files' */
'yourwebsite.com' => 'file1.php',
'otherwebsite.com' => 'file2.php',
'google.com' => 'google.php',
'gfxpoll.com' => 'polls.php',
'etc' => 'etc.php'
);
 
foreach ($refererCheckArray AS $url => $file) /* loop rech row in refererCheckArray key = value
{
    if (stristr($_SERVER['HTTP_RERFERER'], $url)) // is the referer containing the url case insensetive
    {
        include($file);
        break; /* break foreach, no need to contine..*/
    }
}
?>

Code (markup):

and you can use this code as an include!
