why empty?

[scuba]

I call my HTTP_REFERER and have:

if ($HTTP_REFERER == "") {
echo("referer is empty");
}

and it says my referer is empty. How is this possible if my login.php file is calling that file?

my structure is:

login.html -> login.php (which validates and either gives error messages or sends it to another page) -> cpanel.php (where it says my referer is empty)

why would my HTTP_REFERER be empty?

try this:

$from = getenv($HTTP_REFERER);
