http referrer

esthera · Jul 25, 2004

I am trying to create a tell a friend script

I am using

if($SERVER['HTTP_REFERRER'] == NULL){
$sitename = 'Http://www.mysite.org/';
} else {
$sitename = $SERVER['HTTP_REFERRER'];
}

For some reason it is not picking up the referrer.
It is always sending to the index.php page.

what am I doing wrong?

try

if($_SERVER['HTTP_REFERER'] == NULL){
$sitename = 'Http://www.mysite.org/';
} else {
$sitename = $_SERVER['HTTP_REFERER'];
}

Fix the spelling: 'HTTP_REFERER'
HTTP_REFERER is unreliable and thus may sometimes not contain the value of the previous page.
Use echo to display the value of HTTP_REFERER while you are troubleshooting.
Try using the functions isset() or empty() instead of == NULL

okay. now I get the page I am on. (tellfriend.php) as the value.
How do I get the page that I clicked on tellfriend.php from?
