( #3333=superdoc: print w/ replies, xml ) Need Help??
Well, I'm not a veteran DFV user, so I may be stumbling here. But something like this:
use Data::FormValidator; use Data::FormValidator::Constraints::DateTime qw(to_datetime); use CGI; use My::Customer; my $results = Data::FormValidator->check( CGI->new, { constraints => { customer => My::Customer->constraint, date => to_datetime('%D'), } } ); if( $results->success ) { my $date = $results->valid('date'); my $customer = $results->valid('customer'); $date->year; $customer->address->zipcode; }
There's no need to inline the profile like that, of course.

&My::Customer::constraint might look like this:

package My::Customer; use base 'My::Class::DBI'; sub constraint { my $pkg = shift; return sub { my $value = shift; return unless $value =~ /^(\d+)$/; return $pkg->retrieve($value); }; }
But, that's all just guesswork on my part (and completely untested). It does show tremendous potential, that I really should try to incorporate in my own work ;)
