Question

Let say we’ve the following

Objective : User will post certain exact URL $refere to lock viewing text content and only be allowed for view if the viwer is coming from the same exact URL $refere.

$refere = "http://www.site_site.com"; // User will post it
$r = $_SERVER['HTTP_REFERER']; // To get real referral

and i want to do the following

<?PHP

if(stripos($r, $refere) == false){

echo "Wrong";

} else { ?>

echo "Go";

}

?>

It always gives me $r = $_SERVER['HTTP_REFERER']; blank ! so does it deprecated on any PHP version 4 or 5 whatever !

Also

what is the user posted $refere like https:// or missed www. or only posted site_site.com while the $r = $_SERVER['HTTP_REFERER']; showing www.site_site.com

so can anyone help me to adjust this code to be working fine no matter the user posted the $refere link fully or only site_site.com.

Answer 1

The $_SERVER['REFERER'] variable will only be set when you click a link to your page from another page and if the browser (or an eventual proxy or firewall you’re on) isn’t removing the referer header.

To your second question: do some string comparisons. The functions strpos() and substr() will be of great help.
