NAME

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

VERSION

       version 0.40013

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.
