Question about filtered value by Laminas\Filter\Boolean

Hy,

I am confused with the following code and i would like to know what i am doing wrong. I use this code in Mezzio application

$inputFilter = new \Laminas\InputFilter\InputFilter();

$inputFilter->add([
    'name' => 'is_active',
    'required' => false,
    'filters' => [
        [
            'name' => \Laminas\Filter\Boolean::class,
            'type' => \Laminas\Filter\Boolean::TYPE_FALSE_STRING,
        ]
    ],
]);
$data = ['is_active' => 'false'];
$inputFilter->setData($data);
$inputFilter->isValid();

And when I call : $inputFilter->getValues(); I obtain an array with ‘is_active’ value is true not false

And with :

$data = ['is_active' => false];

I obtain ‘isEmpty’ error message.

Does anyone have an explanation for this behavior? is this a bug? is my code wrong?
Thank you in advance for your answers

This problem is based on the wrong configuration because the type is an option and must be set as option:

'filters' => [
    [
        'name'    => Laminas\Filter\Boolean::class,
        'options' => [
            'type' => Laminas\Filter\Boolean::TYPE_FALSE_STRING,
        ],
    ],
],

With your current configuration, the NotEmpty validator is automatically added to the input is_active. But without any options to handle the special type false therefore the validator will fail for this type of value.

There are two options for this case:

  1. Set options to avoid the automatic injection of the NotEmpty validator.
$inputFilter->add(
    [
        'name'              => 'is_active',
        'required'          => false,
        'continue_if_empty' => true, // <-- Add this option
        'filters'           => [
            [
                'name'    => Laminas\Filter\Boolean::class,
                'options' => [
                    'type' => Laminas\Filter\Boolean::TYPE_FALSE_STRING,
                ],
            ],
        ],
    ]
);
  1. Add a custom NotEmpty validator.
$inputFilter->add(
    [
        'name'       => 'is_active',
        'validators' => [
            [
                'name'    => Laminas\Validator\NotEmpty::class,
                'options' => [
                    'type' => Laminas\Validator\NotEmpty::NULL,
                ],
            ],
        ],
        'filters'    => [
            [
                'name'    => Laminas\Filter\Boolean::class,
                'options' => [
                    'type' => Laminas\Filter\Boolean::TYPE_FALSE_STRING,
                ],
            ],
        ],
    ]
);
