Not added to data to table - zend-form

Question

I'm trying to validate the form.
I do not understand why form validation does not take place. Logically, it should work with the simple presence of symbols, but in fact, a simple test:
if (! $form->isValid()) {
echo 'not valid in check';
return ['form' => $form];
}
returned " echo 'not valid in check' "
What is the problem?
Input filter are very simple:
public function getInputFilter()
{
if ($this->inputFilter) {
return $this->inputFilter;
}
$inputFilter = new InputFilter();
$inputFilter->add([
'name' => 'id',
'required' => true,
'filters' => [
['name' => ToInt::class],
],
]);
$inputFilter->add([
'name' => 'text',
'required' => true,
'filters' => [
['name' => StripTags::class],
['name' => StringTrim::class],
],
'validators' => [
[
'name' => StringLength::class,
'options' => [
'encoding' => 'UTF-8',
'min' => 1,
'max' => 1000,
],
],
],
]);
$inputFilter->add([
'name' => 'title',
'required' => true,
'filters' => [
['name' => StripTags::class],
['name' => StringTrim::class],
],
'validators' => [
[
'name' => StringLength::class,
'options' => [
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
],
],
],
]);
$this->inputFilter = $inputFilter;
return $this->inputFilter;
}
Form? for added post:
class PostForm extends Form
{
public function __construct($name = null)
{
// We will ignore the name provided to the constructor
parent::__construct('post');
$this->add([
'name' => 'id',
'type' => 'hidden',
]);
$this->add([
'name' => 'title',
'type' => 'text',
'options' => [
'label' => 'Title',
],
]);
$this->add([
'name' => 'text',
'type' => 'textarea',
'options' => [
'label' => 'Text',
],
]);
$this->add([
'name' => 'submit',
'type' => 'submit',
'attributes' => [
'value' => 'Go',
'id' => 'submitbutton',
],
]);
}
}
Add action, if it need:
public function addAction()
{
$form = new PostForm();
$form->get('submit')->setValue('Add');
$request = $this->getRequest();
if (! $request->isPost()) {
return ['form' => $form];
}
// echo 'test';
$post = new Post();
$form->setInputFilter($post->getInputFilter());
$form->setData($request->getPost());
// echo 'before valid';
if (! $form->isValid()) {
echo 'not valid in check';
return ['form' => $form];
}
echo '\n';
echo 'valid';
$post->exchangeArray($form->getData());
$this->table->savePost($post);
return $this->redirect()->toRoute('post');
}

public function addAction()
{
---------------
if (!$form->isValid()) {
echo 'not valid in check';
return ['form' => $form];
}
---------
}
Validation:
public function getInputFilter()
{
if ($this->inputFilter) {
return $this->inputFilter;
}
$inputFilter = new InputFilter();
$inputFilter->add([
'name' => 'id',
'required' => true,
'filters' => [
['name' => ToInt::class],
],
]);
$inputFilter->add([
'name' => 'text',
'required' => true,
'filters' => [
['name' => StripTags::class],
['name' => StringTrim::class],
],
'validators' => [
[
'name' => StringLength::class,
'options' => [
'encoding' => 'UTF-8',
'min' => 1,
'max' => 1000,
],
],
],
]);
$inputFilter->add([
'name' => 'title',
'required' => true,
'filters' => [
['name' => StripTags::class],
['name' => StringTrim::class],
],
'validators' => [
[
'name' => StringLength::class,
'options' => [
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
],
],
],
]);
$inputFilter->add([
'name' => 'disc',
'required' => true,
'filters' => [
['name' => StripTags::class],
['name' => StringTrim::class],
],
'validators' => [
[
'name' => StringLength::class,
'options' => [
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
],
],
],
]);
$this->inputFilter = $inputFilter;
return $this->inputFilter;
}
