"Back to Previous Page" Link

[Omzy]

I've currently got a "Back to Previous Page" Link using $_SERVER['HTTP_REFERER'] but I only want this link to be displayed if the user got to the page by browsing to it from the site, and not through a direct link from another site.

if (stripos($url,'yourdomain.com')) echo $url;

Can we not get it to check whether the referer was on the website's server or not?

it does

$url = $_SERVER['HTTP_REFERER'];

Well ideally I need a universal solution, i.e. one where I don't have to explicitly specify the domain name. So it needs to basically check whether the referring page was a page on the server that the site is on.

<?php
$exp = explode(".",$_SERVER['HTTP_HOST'],3);
if($exp[2]){
$mydomain = $exp[1];
} else {
$mydomain = $exp[0];
}
$url = $_SERVER['HTTP_REFERER'];
if (strpos($url,$mydomain )) echo $url;
?>
