SannaJ Posted August 10, 2011 Share Posted August 10, 2011 I have this bit of code. If the website visitor doesn't have a referer then the msg "Hello my friend" is shown. But I also would like to display the same msg if the visitors got the word "linkportal" in the refererURL. Can anyone please help me out here? My code so far: $referer = $_SERVER['HTTP_REFERER']; // Getting the referer $$referer = strtolower($$referer); // Make string to lowercase so we can search for "linkportal". if($referer == "") // How to check for blank referer and "linkportal" here? { echo "Hello my friend!"; } Quote Link to comment Share on other sites More sharing options...
Morg. Posted August 10, 2011 Share Posted August 10, 2011 Just learn regex today A bit hard to start but so useful in the end $hello_my_friend_valid_referer="linkportal|^$|etc."; $t=preg_match("/($hello_my_friend_valid_referer)/i",$_SERVER['HTTP_REFERER']); if($t==false || $t==0){ // woot no match, this should be good ? }else{ // woot match, this should be good ? } Quote Link to comment Share on other sites More sharing options...
Alex Posted August 10, 2011 Share Posted August 10, 2011 Something like.. $referer = $_SERVER['HTTP_REFERER']; if(empty($referer) || strpos($referer, 'linkportal') !== false) { echo "Hello my friend!"; } empty strpos Quote Link to comment Share on other sites More sharing options...

SannaJ Posted August 10, 2011 Author Share Posted August 10, 2011 By the way, why doesn't this work: $product = $_GET['product']; $referer = $_SERVER['HTTP_REFERER']; if(empty($product)) { echo "<html><head>"; echo "<meta http-equiv=refresh content=0;url=http://errorurl.com>"; echo "</head></html>"; } If I surf to www.myurl.com/script.php there is no product set and it should send me to the errorurl but it doesn't.

SannaJ Posted August 10, 2011 Author Share Posted August 10, 2011 Hmmm... Maybe $products isn't 100% empty when trying to get the data with GET? Quote Link to comment Share on other sites More sharing options...
