Hi,
Wow, I didn't know the part of that.
How kind of you, Carl.
Finally, I decided to add hidden fields dynamically in perl codes like this:
my $form = $c->stash->{ form };
my $position = $form->get_element({ type => 'Submit'});
my @hidden = qw( foo bar );
foreach my $hidden ( @hidden ) {
for ( $c->req->param( $hidden ) ) {
my $element = $form->element({ type => 'Hidden', name => $hidden,
value=> $_ });
$form->insert_after( $element, $position );
}
}
I would build urls according to hidden fields' value using jQuery and
I think multiple value field is easier to handle.
Thank you all the same.
