Hi Stephen,
The Block sub-class pasted below should handle the incrementing Block ID.
You would just need to change the appropriate:
- type: Block
line to something like:
- type: MyBlock
auto_block_id: 'rt_%r'
Once I'm back on a development machine, I'll move this into the core
Block element - so after the next cpan release, you'll be able to
change the 'MyBlock' back to 'Block', and auto_block_id() will still
work.
BTW, you can give a 'name' to any Block to allow you to grab it easily
within your perl code - it won't be output in the rendered xhtml.
package HTML::FormFu::Element::MyBlock;
use strict;
use base 'HTML::FormFu::Element::Block';
use Class::C3;
__PACKAGE__->mk_item_accessors(qw/ auto_block_id /);
sub prepare_id {
my ( $self, $render ) = @_;
if ( !defined $render->{attributes}{id}
&& defined $self->auto_block_id
&& defined $self->repeatable_count
)
{
my $id = $self->auto_block_id;
my $count = $self->repeatable_count;
$id =~ s/%r/$count/g;
$render->{attributes}{id} = $id;
}
return $self->next::method( $render );
}
1;
Is there anything I've missed from your original request?
Cheers,
Carl
