$HTTP_REFERER problems...

[bluntster]

Hi,
I want to track referrers to my site, but I can't seem to get hold of the $HTTP_REFERER or $REMOTE_ADDR variables. Here's what I'm doing:

<?
$web_referrer = getenv("$HTTP_REFERER");
$remote_id = getenv("$REMOTE_ADDR");
$date = date("Y-m-d H:i:s",time());

$sql = "INSERT INTO referrer_log(referrer,IP,date) VALUES ('$web_referrer','$remote_id','$date')";
$result = mysql_query($sql,$db);
?>

My $web_referrer and $remote_id vars are always empty. What am I doing wrong?
Thanks,

Neil

$web_referrer = getenv("HTTP_REFERER");
$remote_id = getenv("REMOTE_ADDR");

You don't need the $, otherwise it sets it to a null string value. You could also just do this:

$web_referrer = $HTTP_REFERER;
$remote_id = $REMOTE_ADDR;
