I've found another post (ZF2 InputFilter not validating fieldset) for my issue, but it doesn't helped.

I have a Category Entity and i want to validate the length of the title.
So my Model (without the existing getter and setter)

class Category

 /**
 * @var int
 */
 private $id;

 /**
 * @var string
 */
 private $name;

My Form for the Category:

class CategoryForm extends Form


 public function init()
 

 $this->setHydrator(new ClassMethods(false));
 $this->setObject(new Category());
 $this->setInputFilter(new CategoryFilter());

 $this->add([
 'name' => 'id',
 'type' => 'hidden'
 ]);

 $this->add([
 'name' => 'name',
 'type' => 'text'
 ]);

 $this->add([
 'name' => 'submit',
 'type' => 'submit'
 ]);
 

And the Filter which currently not working.

class CategoryFilter extends InputFilter

 public function init()
 
 $this->add([
 'name' => 'name',
 'required' => true,
 'filters' => [
 ['name' => StringTrim::class]
 ],
 'validators' => [
 [
 'name' => StringLength::class,
 'options' => [
 'min' => 5
 ]
 ]
 ]
 ]);
 

And if someone needed my addAction in the Controller:

public function addAction()

 $request = $this->getRequest();

 if ($request->isPost()) 
 $this->form->setData($request->getPost());

 if ($this->form->isValid()) 
 $this->mapper->save($this->form->getData());

 $this->redirect()->toRoute('categories');
 
 

 return [
 'form' => $this->form
 ];

In every example which i found, it should be working. But my form is never validated nor filtered (with the trim).

Did i forget something? Why it doesn't work?

So i've changed a little bit.

The Category Form goes to:

class CategoryForm extends Form


 public function init()
 
 $this->add(array(
 'type' => CategoryFieldSet::class,
 'options' => array(
 'use_as_base_fieldset' => true,
 ),
 ));

 $this->add([
 'name' => 'submit',
 'type' => 'submit'
 ]);
 

I changed also the Filter

class CategoryFilter extends InputFilter

 public function __construct()
 
 $this->add([
 'name' => 'name',
 'required' => true,
 'filters' => [
 ['name' => StringTrim::class]
 ],
 'validators' => [
 [
 'name' => StringLength::class,
 'options' => [
 'min' => 5
 ]
 ]
 ]
 ]);
 

And after this i defined the FieldSet with the validators:

class CategoryFieldSet extends Fieldset implements InputFilterProviderInterface

 /**
 *
 */
 public function init()
 
 $this->setHydrator(new ClassMethods(false));
 $this->setObject(new Category());

 $this->add([
 'name' => 'id',
 'type' => 'hidden'
 ]);

 $this->add([
 'name' => 'name',
 'type' => 'text',
 ]);
 

 /**
 * Should return an array specification compatible with
 * @link ZendInputFilterFactory::createInputFilter().
 *
 * @return array
 */
 public function getInputFilterSpecification()
 
 $filter = new CategoryFilter();

 return $filter->getInputs();
 

After changing this i get the expected error message like:

The input is less than 5 characters long
