HTML::FormHandler::ManUser:ContributedoPerlnDocr::Manual::RenderingCookbook(3)

NAME
       HTML::FormHandler::Manual::RenderingCookbook - rendering	recipes

VERSION
       version 0.40068

SYNOPSIS
       Collection of rendering recipes

NAME
       HTML::FormHandler::Manual::Rendering::Cookbook

Recipes
   Custom renderer, custom attributes
       You want	to be able to specify the attributes that are rendered in the
       'td' tag	of the table renderer...

       First make your own copy	of 'HTML::FormHandler::Widget::Wrapper::Table,
       in your own name	space, and specify that	name space in the
       'widget_name_space' for the form.

       Change this line	in the Table wrapper:

	   $output .= '<td>' . $self->do_render_label($result) . '</td>';

       to this:

	   my $td_attr = process_attrs($self->get_tag('td_attr') || {} );
	   $output .= "<td$td_attr>" . $self->do_render_label($result) . '</td>';

       Now you can specify the attributes for the 'td' tag on a	field:

	   has_field 'foo' => (	tags =>	{ td_attr => { class =>	['emph', 'label'] } } );

   Render a collection of checkboxes like a checkbox group
   Add a 'required' class to labels
       Create a	custom widget wrapper:

	   package MyApp::Form::Widget::Wrapper::CustomLabel;

	   use Moose::Role;
	   with	'HTML::FormHandler::Widget::Wrapper::Simple';

	   sub render_label {
	       my ($self) = @_;
	       return '<label class="label' . ($self->required ?
		   ' required' : '') .	'" for="' . $self->id .	'">' .
			$self->html_filter($self->loc_label) . ':
		   </label>';
	   }

       Or enable html5 output which adds a 'required' attribute.

       Or use the 'html_attributes' callback:

	   <in a form>
	   sub html_attributes {
	       my ( $self, $field, $type, $attr	) = @_;
	       push @{$attr->{class}}, 'required'
		   if (	$type eq 'label' && $field->required );
	   }
