About PHP Referrer

[jeboy]

I write a code that will show up the referers url, I used $HTTP_REFERER, $_SERVER['HTTP_REFERRER'] but it doesnt work. Here's my code:

[color=green][font=Verdana][b]$ref = @$_SERVER["REFERER"];
// try to catch the referrer
if (empty($ref) && !empty($HTTP_REFERER)){
$ref = $HTTP_REFERER;
}
echo 'Your referer to this page is ';
echo $ref;
[/b][/font][/color]

I'd like to use that method for me to track the page in which the visitor used to click the link and the visitor will be redirected back to that page.

Hope you could help me, thanks

All you need to know about tracking visitors:

The referer variable is:
<?php

$_SERVER['HTTP_REFERER']

?>

[code]
<?php
$host=apache_request_headers();
echo "\$host['Referer'] = {$host['Referer']}\n";
echo "\$_SERVER['HTTP_REFERER'] = {$_SERVER['HTTP_REFERER']}\n";
?>
[/code]

Thanks! I use dreamweaver in writing php scripts, when I type the code $_SERVER['HTTP_REFERER'], it auto completes to [color=red][b]HTTP_REFERRER[/b][/color] instead of [color=green][b]HTTP_REFERER[/b][/color].

Dreamweaver + PHP =  >:(

That why most php programmers use notepad lol.

All the best redarrow.

Just to note that referals are not reliable - they depend on the previous host using transfers and the client to actually submit the data, which doesn't always happen. :)
