NAME

       HTML::FormHandler::Manual::FromDFV - converting from Data::FormValidator

VERSION

       version 0.40013

SYNOPSIS

       Manual Index

       Cheatsheet for converting from Data::FormValidator.

DESCRIPTION

       Information that's useful when switching from Data::FormValidator to HTML::FormHandler. There's not a lot here yet, so if you have
       something to add, patches are welcome.

       In a general way, FormHandler doesn't have nearly so many "special" checks as Data::FormValidator. It would be possible to implement many
       of them, but there hasn't been much demand for them. So far FormHandler users seem to be satisfed with the "do your own checks in a Perl
       method" solution. Because of the greater complexity of FormHandler's data model - with Repeatable arrays and nested compounds, etc - it's
       somewhat harder to do some of them automatically.

Differences/conversions
       dependencies
	   In FormHandler, 'dependency' is the equivalent of 'dependency_group', without the key names.

	   The other variations of dependencies in DFV are not implemented in FormHandler, and would normally be done in a form's 'validate' sub.

       trim, filters
	   A 'trim' filter is installed by default in FormHandler; it's a special version of an apply action, and can be set to a transform or
	   Moose type. See the documentation in HTML::FormHandler::Field#trim.

	   Transforms and inflations/deflations do not change what is presented in the form unless you set the 'fif_from_value' flag on the field.

       FV_length_between, FV_max_length, FV_min_length
	   Use text fields with 'minlength' and 'maxlength' attributes.

       FV_eq_with
	   Perform your own checks in the form 'validate' sub.

	       sub validate {
		   my $self = shift;
		   if( $self->field('one')->value eq $self->field('two')->value ) {
		   }
	       }

Constraints
       The simple constraints from Data::FormValidator::Constraints can be used directly in a FormHandler form:

	   use Data::FormValidator::Constraints ('match_state');
	   has_field 'my_state' => (
	       apply => [ { check => &match_state, message => 'Invalid State' } ] );

       email
	   Use the 'Email' field type, or use the the FH Moose Type, 'email'.

		has_field 'email' => ( type => 'Email' );
		-- or --
		use HTML::FormHandler::Types ('Email');
		has_field 'email' => ( apply => [ Email ] );

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.
