$ENV{'HTTP_REFERER'} Can't Post
my $refpage = $ENV{'HTTP_REFERER'} ||"http://www.domain.com/") ;

What I am hoping for is. If it has a HTTP_REFERER great, if not set it to http://www.domain.com/

Didn't get an error but didn't set http://www.domain.com/ as $refpage.

Thanks for the help.

I would do something like:

my $refpage = $ENV{'HTTP_REFERER'};

if (!$refpage) {
$refpage = "http://www.domain.com";
}

this should work:

my $refpage = $ENV{'HTTP_REFERER'} || "http://www.domain.com/";


if it's not it could be a problem somewhere else in the script.

You seem to have an excess closing parenthesis on that line of code. Is that the problem?

Yes that was the problem. Originally I had something like this my ($refpage = $ENV{'HTTP_REFERER'} ||"http://www.domain.com/") ; when that didn’t work I removed that first parentheses but missed the one at the end. The code KevinR gave me my $refpage = $ENV{'HTTP_REFERER'} ||"http://www.domain.com/" ; works fine.

Thanks for the help.
