Pizza, because input filter is defined on ModelPizza. So plz check your Model first or plz write the Model so we can sort out your problem. Thanks. and make sure you have added this on your Model alsonamespace Pizza\Model; use Zend\InputFilter\InputFilter; use Zend\InputFilter\InputFilterAwareInterface; use Zend\InputFilter\InputFilterInterface; class Pizza implements InputFilterAwareInterface {...– Prashant Vardhan Singh
