Zend Framework 2 - Integer Form Validation

I've got the following problem. I wrote (based on the tutorial) a form validation. The text fields work just fine but the integer field behave odd.

This is my validator:

        $inputFilter->add($factory->createInput(array(
            'name'     => 'zip',
            'required' => false,
            'filters'  => array(
                array('name' => 'Int'),
            ),
        )));

It lies within my Entity.php like the other filters. The odd thing is that this one accepts not even a string but ignores the required when I set it to true. I tried to replace Int with Digits which then causes the form to accept required but still accepts strings.

Any ideas? Thanks!

Is it a field of type number or of type text? Considering a text-input will result in a string and only a number would send the integer, this is where you may have your thought-problem - Sam

Try using the Between validator:

$inputFilter->add($factory->createInput(array(
            'name'     => 'zip',
            'required' => true,
            'filters'  => array(
                array('name' => 'Int'),
            ),
            'validators' => array(
              array(
                  'name' => 'Between',
                  'options' => array(
                      'min' => 1,
                      'max' => 1000,
                  ),
              ),
            ),
        )));

this is a old topic but i should mention that Filters don't cause validation errors, they work in background and do their jobs silently .

for example Int filter will remove any non-integer from the input , so when you do $form->getData() the field with the Int filter will only have integer values and 0 if its empty.

 array(
                        'name' => 'not_empty',
                    ),
                    array(
                        'name' => 'Digits',
                    ), array(
                        'name' => 'Between',
                        'options' => array(
                            'min' => 0,
                            'max' => 1,
                        ),
                    ),
