NAME ^

Gantry::Utils::FormErrors - A CRUD form validation error object

SYNOPSIS ^

A typical example:

    use Gantry::Plugins::CRUD;
    use Gantry::Utils::FormErrors;

    my $crud_obj = Gantry::Plugins::CRUD->new(
        #...
        validator => \&my_validator,
    );

    sub my_validator {
        my $opts   = shift;
        my $params = $opts->{ params };
        my $form   = $opts->{ form   };

        my %missing;
        my @errors;

        if ( not $params->{ password } ) {
            $missing{ password }++;
        }
        if ( $params->{ password } =~ /$params->{ user_name }/ ) {
            push @errors, 'Password cannot contain user name';
        }
        # ... other similar tests

        my $error_text = join "\n<br /><b>Error:</b> ", @errors;

        $form->{ error_text } = $error_text;

        return Gantry::Utils::FormErrors->new(
            {
                missing    => \%missing,
            }
        );
    }

The rest is handled by the CRUD plugin and the default template (form.tt).

DESCRIPTION ^

This module provides objects which respond to the same API as Data::FormValidator::Results (or at least the parts of that API which Gantry normally uses).

Use this module in your Gantry::Plugins::CRUD validator callback.

METHODS ^

new

Constructor, expects a hash reference with the following keys (all are optional):

    missing    - a hash reference keyed by missing field names
    invalid    - a hash reference keyed by invalid field names
has_missing

Returns 1 if there are any keys in the missing hash.

has_invalid

Same as has_missing, except that it checks the invalid hash.

missing

If called without arguments, returns number of missing fields. If call with the name of a field, returns 1 if that field is a key in the missing hash and 0 otherwise.

invalid

Same as missing, but checks the invalid hash.

get_missing_hash

Returns the hash reference of missing fields. Keys are field names values are usually 1 (but they must be true).

This is useful if two validation routines are cooperating to form the final lists.

get_invalid_hash

Returns the hash reference of invalid fields. Keys are field names values are usually 1 (but they must be true).

This is useful if two validation routines are cooperating to form the final lists.
