It is common that you need to make sure user entered same value in two

I haven't found something like that in DFV - am I'm missing something?
It's not built-in, but perhaps it should be, because it so common to
have a password or e-mail confirmation field.
Here's the DFV 4.0 constraint method I use for this:
=head2 eq_with
password => eq_with('password_confirm'),
Compares the current field to another field
=cut
sub eq_with {
my ($other_field) = @_;
return sub {
my $dfv = shift;
$dfv->name_this('eq_with');
my $curr_val = $dfv->get_current_constraint_value;
my $data = $dfv->get_input_data;
# Sometimes the data comes through both ways...
my $other_val = (ref $data->{$other_field})
? $data->{$other_field}[0] : $data->{$other_field};
return ($curr_val eq $other_val);
}
}
