Hi, please excuse my ignorance but I have very limited PHP knowledge.. In
your sample script below would I include this at the top of the page I want
to protect?? Let's say the page I want the user to go to is called
denied.htm, where in the file would I place this??
Many thanks, I realize it's not bulletproof and easily hackable but it's
important we have this feature.
$validDomains = array('www.mydanaher.com', 'www.bar.com', 'www.baz.com');
$isOk = false;
foreach($validDomains as $domain) {
if(stripos($_SERVER['HTTP_REFERER'], $domain)) {
$isOk = true;
break;
}
}
if(!$isOk) {
//redirect to somewhere else
}
