Form::Processor::Field::DateTimeDMYHM - DEPRECATED example of a compound field

SYNOPSIS

Top

See Form::Processor

DESCRIPTION

Top

This is a compound field that uses modified field names for the sub fields instead of using a separate sub-form.

This is not well tested and should only be used after extensive testing. It's more of an example than a real field.

Widget

Fields can be given a widget type that is used as a hint for the code that renders the field.

This field's widget type is: "Compound".

Subclass

Fields may inherit from other fields. This field inherits from: "Field".

DEPENDENCIES

DateTime
