in reply to Data::FormValidator, equivalent to "require_some_regexp"?

I think the mistake you are making is assuming that the DFV profile has to be hard-coded or that the DFV profile has to do all the work.

Dynamically generate a DFV profile. It is only a hash structure so there is no reason that this will not work.

use CGI;

my $q = CGI->new();

my @fields = $q->param();

my @foo_fields;
for my $field (@fields) {
  push @foo_fields, $field if $field qr{^foo_}xm;
}

my $profile = {};
$profile->{require_some} => { foo_fields => [1, @foo_fields ] };

    I think that code can be tightened up a bit: 
    $profile->{require_some} = {
    foo_fields => [ 1, grep /^foo_\d+$/, $q->param ]
};

    But apart from that I'm afraid this is the best solution available to me. Thanks!
