NAME

6       HTML::FormHandler::Field::Compound - field consisting of subfields
7

VERSION

9       version 0.40068

SYNOPSIS

12       This field class is designed as the base (parent) class for fields with
13       multiple subfields. Examples are HTML::FormHandler::Field::DateTime and
14       HTML::FormHandler::Field::Duration.
15
16       A compound parent class requires the use of sub-fields prepended with
17       the parent class name plus a dot
18
19          has_field 'birthdate' => ( type => 'DateTime' );
20          has_field 'birthdate.year' => ( type => 'Year' );
21          has_field 'birthdate.month' => ( type => 'Month' );
22          has_field 'birthdate.day' => ( type => 'MonthDay');
23
24       If all validation is performed in the parent class so that no
25       validation is necessary in the child classes, then the field class
26       'Nested' may be used.
27
28       The array of subfields is available in the 'fields' array in the
29       compound field:
30
31          $form->field('birthdate')->fields
32
33       Error messages will be available in the field on which the error
34       occurred. You can access 'error_fields' on the form or on Compound
35       fields (and subclasses, like Repeatable).
36
37       The process method of this field runs the process methods on the child
38       fields and then builds a hash of these fields values.  This hash is
39       available for further processing by "actions" in
40       HTML::FormHandler::Field and the validate method.
41
42   widget
43       Widget type is 'compound'
44
45   build_update_subfields
46       You can set 'defaults' or other settings in a 'build_update_subfields'
47       method, which contains attribute settings that will be merged with
48       field definitions when the fields are built. Use the 'by_flag' key with
49       'repeatable', 'compound', and 'contains' subkeys, or use the 'all' key
50       for settings which apply to all subfields in the compound field.
