HTML::...romDFV(3pm)

🌸 NAME 🌸

okay so this is HTML::FormHandler::Manual::FromDFV(3pm) — the User Contributed Perl Documentation page — and it's literally the guide for converting from Data::FormValidator, bestie. 🦋

✨ VERSION ✨

version 0.40068 — that's the exact number, no cap. 💅

🎀 SYNOPSIS 🎀

Manual Index

Cheatsheet for converting from Data::FormValidator. 🍓

🌈 DESCRIPTION 🌈

okay so here's the tea: this page has info 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 — fr fr. 🫶

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 satisfied 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. periodt. 💅

💥 FV_eq_with 💥

Perform your own checks in the form validate sub, like this:

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 FH Moose Type, email. Both slay:

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