How to show link on page?

[TheJoey]

Is there a way to show the link of the previous page you were on.

 

I tried using $_Server['HTTP_REFERER'];

 

completly stuck at the moment

Have you tried adding a quick phpinfo(); to your script to make sure that

the hosting web server is actually providing the referer information?

[TheJoey]

session.referer_check no value no value

 

what should i be looking for?

[inversesoft123]

Manytime refere information is blocked by webhost or many browsers like KHTML safari/ many mobile/ PDA browsers do not allow referal information. In this case you may use database to store current page of user or  u can use PHP GET for previous page

 

function liveURL()
{
$s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : ""; $protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s; $port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]); return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI']; } function strleft($s1, $s2) { return substr($s1, 0, strpos($s1, $s2));
}

 

$liveurl = liveURL();

http://www.domain.com/currentpage.php?liveurl=$liveurl

?
