HTML::FormHandler::FieUserCContributed PeHTML::FormHandler::Field::Compound(3)

NAME
       HTML::FormHandler::Field::Compound - field consisting of	subfields

VERSION
       version 0.40067

SYNOPSIS
       This field class	is designed as the base	(parent) class for fields with
       multiple	subfields. Examples are	HTML::FormHandler::Field::DateTime and
       HTML::FormHandler::Field::Duration.

       A compound parent class requires	the use	of sub-fields prepended	with
       the parent class	name plus a dot

	  has_field 'birthdate'	=> ( type => 'DateTime'	);
	  has_field 'birthdate.year' =>	( type => 'Year' );
	  has_field 'birthdate.month' => ( type	=> 'Month' );
	  has_field 'birthdate.day' => ( type => 'MonthDay');

       If all validation is performed in the parent class so that no
       validation is necessary in the child classes, then the field class
       'Nested'	may be used.

       The array of subfields is available in the 'fields' array in the
       compound	field:

	  $form->field('birthdate')->fields

       Error messages will be available	in the field on	which the error
       occurred. You can access	'error_fields' on the form or on Compound
       fields (and subclasses, like Repeatable).

       The process method of this field	runs the process methods on the	child
       fields and then builds a	hash of	these fields values.  This hash	is
       available for further processing	by "actions" in
       HTML::FormHandler::Field	and the	validate method.

   widget
       Widget type is 'compound'

   build_update_subfields
       You can set 'defaults' or other settings	in a 'build_update_subfields'
       method, which contains attribute	settings that will be merged with
       field definitions when the fields are built. Use	the 'by_flag' key with
       'repeatable', 'compound', and 'contains'	subkeys, or use	the 'all' key
       for settings which apply	to all subfields in the	compound field.
