Re: [dfv] Multiple constraint_methods for a field

[Jonas B. N. <jo...@gm...>]

Hi Dave.

Not the prettiest solution. but you could do a two phase validation:

my $dfv = Data::FormValidator->new({
   profile_1 => { # usual profile definition here },
   profile_2 => { # another profile definition },
});

my $results1 = $dfv->check(\%input_hash,'profile_1’);

my $results2 = $dfv->check(\%input_hash,'profile_2');

Examples lifted from the documentation:
