Validator with Zend\I18n\Validator\DateTime is always required

[alexisbmills]

I am attempting to use the DateTime validator in an Apigility project. The configuration is set to not be required and continue if empty, however the validator always returns a validation error.

Input

{"name": "Joe Public", "email": "[email protected]"}

Validator configuration

1 => array(
    'name' => 'dateField',
    'required' => false,
    'filters' => array(),
    'validators' => array(
        0 => array(
            'name' => 'Zend\\I18n\\Validator\\DateTime',
            'options' => array(
                'pattern' => 'Y-m-d\TH:iP',
                'message' => 'Date format must be Y-m-d\TH:iP',
            ),
        ),
    ),
    'allow_empty' => true,
    'continue_if_empty' => true,
    'description' => 'Date field',
),

Error message

{
  "validation_messages": {
    "dateOfBirth": {
      "datetimeInvalid": "Date format must be Y-m-d\TH:iP"
    }
  },
  "type": "http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html",
  "title": "Unprocessable Entity",
  "status": 422,
  "detail": "Failed Validation"
}

I cannot reproduce.

To attempt to reproduce, I added zend-i18n as a dev dependency (composer require --dev zendframework/zend-i18n), and then edited test/ContentValidationListenerTest.php to do the following:

• Import Zend\I18n\Validator\DateTime
• Add the following test case:

    public function testUnrequiredDateTimeValidatorShouldNotResultInInvalidationOfSet()
    {
        $services = new ServiceManager();
        $factory  = new InputFilterFactory();
        $services->setService('FooValidator', $factory->createInputFilter([
            'dateField' => [
                'name' => 'dateField',
                'required' => false,
                'validators' => [
                    [
                        'name' => DateTime::class,
                        'options' => [
                            'pattern' => 'Y-m-d\TH:iP',
                            'message' => 'Invalid date format',
                        ],
                    ],
                ],
                'allow_empty' => true,
                'continue_if_empty' => true,
                'description' => 'Date Field',
            ],
        ]));
        $listener = new ContentValidationListener(
            [
                'Foo' => [
                    'GET' => 'FooValidator',
                ],
            ],
            $services,
            ['Foo' => 'foo_id']
        );

        $request = new HttpRequest();
        $request->setMethod('POST');

        $matches = $this->createRouteMatch(['controller' => 'Foo', 'foo_id' => 3]);

        $dataParams = new ParameterDataContainer();
        $dataParams->setBodyParams([
            'name' => 'Joe Public',
            'email' => '[email protected]',
        ]);

        $event = new MvcEvent();
        $event->setRequest($request);
        $event->setRouteMatch($matches);
        $event->setParam('ZFContentNegotiationParameterData', $dataParams);

        $this->assertNull($listener->onRoute($event));
        $this->assertNull($event->getResponse());
    }

null is expected when validation passes; otherwise, it will return an ApiProblem.

The test passed.

Can you update your dependencies and report back if the problem still exists? If it does, we'll need more information.
