perl error

I am geting information from user
and want to print an error message if any of the fields were empty. But i don't wanna go thorought each entry one bye one with a different if statement for each of them. Is there any way to do this all in one or some easier way of doing it rather than checking each entry ??

If your fields data is in an array called @fields then you can do:

foreach $field (@fields) {
      error_message() if (!defined($field));
use CGI;
@names = $query->param
foreach $name (@names) {
      error_message() if (!defined($name));

where error_message() is a subroutine which handles the error message you'd like to output to the user.
