Log HTTP_REFERER.

[joeiscoolone]

I am having trouble logging the refering page. I try to log the refering page but when I check the database it's just a blank entry. Is there another way to log the refering page? This is the code I used:

<?php
mysql_connect("", "", "") or die(mysql_error()); 
mysql_select_db("") or die(mysql_error());
$re = addslashes($_SERVER["HTTP_REFERER"]);
$query="INSERT INTO `tracker`(`pagesr`) VALUES ('$re');";
$result = mysql_query($query);
if (!$result) die(mysql_error());
print_r($_SERVER); exit;
?>

The value does not get logged and when I print out the value it's a bunch of stuff that has nothing to do with the refering page, I was told that the value I was looking for was in the stuff that was printed out but I didn't see anything in there that had to do with the refering page. Can someone please tell me how to log the refering page and print it out.

NOTE: I took the host,username,password and database name out for security reasons.

unfortunately, HTTP_REFERER is not reliable.. ive run into the same problem trying to determine referring pages.. a value is returned only when the user takes an action directly linking them to your page, and i am unsure of any other way..

you could try checking to see if the variable is null, and only enter it if it is not. that way, you can still get some referring pages and not all the blank entries.

So ... ah ... what was the "bunch of stuff"? I'm just curious: if the contents are consistently garbage then something odd would appear to be wonky at your end somewhere.

But notaloser is right; HTTP_REFERER can't be relied upon; there may not be a referring page, and clients aren't obliged to include the Referer: header even if there is such a page.
