use Zend\InputFilter\InputFilter; use Zend\Form\Form; // Create a new input filter object $inputFilter = new InputFilter(); // Add validation rules for the "name" field $inputFilter->add([ 'name' => 'name', 'required' => true, 'filters' => [['name' => 'StripTags'], ['name' => 'StringTrim']], 'validators' => [ ['name' => 'StringLength', 'options' => ['min' => 2, 'max' => 50]], ], ]); // Create a new form object $form = new Form('my-form'); // Set the input filter for the form $form->setInputFilter($inputFilter);In this example, we first create an InputFilter object and add validation rules for the "name" field. We require this field to be present, and apply two filters to it: StripTags and StringTrim. We also add a validator that ensures that the length of the field is between 2 and 50 characters. We then create a new Form object and call its setInputFilter method, passing in the InputFilter object that we just created. This associates the input filter with the form, so that when the user submits the form, the input values will be validated according to the rules we defined. Overall, the setInputFilter method is a useful tool for ensuring that user input is properly validated and sanitized before being processed by your application. By adopting this approach to form processing, you can build more robust and secure web applications.
