no value

whenever I echo this:

$from = $HTTP_REFERER;

nothing comes up. Why would it be empty?

Thanks,
Steve

Are you linking to the page or just typing the address in? If you just go straight to the address (without traversing a link first) the variable would not be populated.

I'm having info validated from an html by a php file. Then this php file goes to another php file which uses the referer script, but the referer variable is blank and messes up my program.

try this:

$from = getenv($HTTP_REFERER);
