HTML::...mpound(3pm)

💖 NAME 💖

okay bestie, this is the 3pm manual page for HTML::FormHandler::Field::Compound — a field consisting of subfields. Periodt. 🎀

🌸 VERSION 🌸

version 0.40068 — yes ma'am, that’s the one. ✨

✨ 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 — like a literal dot, not a vibe:

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. iconic, honestly. 💅

🦋 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. lowkey very organized of you. 🌈
