HTML::FormHandler::FieUserCContributed PeHTML::FormHandler::Field::Compound(3)NAMEHTML::FormHandler::Field::Compound - field consisting of subfields
VERSION
version 0.35005
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.
Example:
has_field 'date_time' => (
type => 'Compound',
actions => [ { transform => sub{ DateTime->new( $_[0] ) } } ],
);
has_field 'date_time.year' => ( type => 'Text', );
has_field 'date_time.month' => ( type => 'Text', );
has_field 'date_time.day' => ( type => 'Text', );
