NAME

HTML::FormFu::Validator - Validator Base Class

SYNOPSIS

DESCRIPTION

METHODS

CORE VALIDATORS

BEST PRACTICES

Try to avoid using callbacks if possible. Below is a more maintainable and reusable approach, which also keeps the code out of the controller.

A normal application's directory would contain:

lib/HTML/FormFu/Constraint/MyApp/
lib/HTML/FormFu/Validator/MyApp/
lib/HTML/FormFu/Plugin/MyApp/
etc.

Then, the form config file would just need:

validator: 'MyApp::SomeValidator'

And the class would be something like this:

package HTML::FormFu::Validator::MyApp::SomeValidator;
use strict;
use warnings;
use base 'HTML::FormFu::Validator';

sub validate_value {
    my ( $self, $value, $params ) = @_;

    my $c = $self->form->stash->{context};

    return 1 if $c->model('DBIC')->is_valid($value);

    # assuming you want to return a custom error message
    # which perhaps includes something retrieved from the model
    # otherwise, just return 0
    die HTML::FormFu::Exception::Validator->new({
        message => 'custom error message',
    });
}

1;
