in reply to How do I detect and handle empty form fields?

Are you using CGI.pm? If so, you could use something like this:

use CGI;
my $query = new CGI;
my @fields = qw/name phone email/;
for my $field (@fields) {
    print "$field is not defined" unless
        defined $query->param($field);
}

@fields should hold the fields that you want to validate. Does that make sense?
