Re: How do I detect and handle empty form fields?

[Russ]

my @InvalidFields =
  grep {not defined CGI::param($_) or CGI::param($_) eq ''} CGI::param
+();

@InvalidFields will now contain the names of any empty fields.

Evaluate @InvalidFields in a scalar context to see how many empty fields there are.

if (@InvalidFields){
  # You have some empty fields, so do something about them
}

This general technique will work even if you are not using CGI...
