Validation

[Stefan Adams]

How can I set up a validation to require one parameter of a group? For example, I need to require City and State, or Zip.

Seems

my $validation = $c->validation;
$validation->required('City')->in('Pyongyang');
$validation->required('State')->in('North Korea');
$validation->required('Zip')->in('007007');
my $bool = ( $validation->is_valid('City') && $validation->is_valid('State') )
    || $validation->is_valid('Zip');
