Failed to Insert Data with zend-form - php

Question

I have a mode named Album as follows:
namespace Album\Model;
// Add the following import statements:
use DomainException;
use Zend\Filter\StringTrim;
use Zend\Filter\StripTags;
use Zend\Filter\ToInt;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
use Zend\Validator\StringLength;
class Album {
public $id;
public $artist;
public $title;
private $inputFilter;
public function exchangeArray(array $data) {
$this->id = !empty($data['_id']) ? $data['_id'] : null;
$this->artist = !empty($data['artist']) ? $data['artist'] : null;
$this->title = !empty($data['title']) ? $data['title'] : null;
}
public function setInputFilter(InputFilterInterface $inputFilter) {
throw new DomainException(sprintf(
'%s does not allow injection of an alternate input filter', __CLASS__
));
}
public function getInputFilter() {
if ($this->inputFilter) {
return $this->inputFilter;
}
$inputFilter = new InputFilter();
$inputFilter->add([
'name' => 'id',
'required' => true,
'filters' => [
['name' => StripTags::class],
['name' => StringTrim::class],
],
'validators' => [
[
'name' => StringLength::class,
'options' => [
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
],
],
],
]);
$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' => 'artist',
'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;
}
public function getArrayCopy() {
return [
'id' => $this->id,
'artist' => $this->artist,
'title' => $this->title,
];
}
}
And a form named AlbumForm as follows:
namespace Album\Form;
use Zend\Form\Form;
class AlbumForm extends Form
{
public function __construct($name = null)
{
// We will ignore the name provided to the constructor
parent::__construct('album');
$this->add([
'name' => 'id',
'type' => 'hidden',
]);
$this->add([
'name' => 'title',
'type' => 'text',
'options' => [
'label' => 'Title',
],
]);
$this->add([
'name' => 'artist',
'type' => 'text',
'options' => [
'label' => 'Artist',
],
]);
$this->add([
'name' => 'submit',
'type' => 'submit',
'attributes' => [
'value' => 'Go',
'id' => 'submitbutton',
],
]);
}
}
And a controller named AlbumController in which I have addAction as follows:
public function addAction() {
$form = new AlbumForm();
$form->get('submit')->setValue('Add');
$request = $this->getRequest();
if (!$request->isPost()) {
return ['form' => $form];
}
$album = new Album();
$form->setInputFilter($album->getInputFilter());
$form->setData($request->getPost());
if (!$form->isValid()) {
return ['form' => $form];
}
$album->exchangeArray($form->getData());
$this->table->saveAlbum($album);
return $this->redirect()->toRoute('album');
}
The module.config.php file is as follows and I see no problem with routing:
return [
// The following section is new and should be added to your file:
'router' => [
'routes' => [
'album' => [
'type' => Segment::class,
'options' => [
'route' => '/album[/:action[/:id]]',
'constraints' => [
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
],
'defaults' => [
'controller' => Controller\AlbumController::class,
'action' => 'index',
],
],
],
],
],
'view_manager' => [
'template_path_stack' => [
'album' => __DIR__ . '/../view',
],
],
];
but, I cannot add a new album to the db. Once, I press fill the form and hit 'Add' in the Add form, nothing is added and I remain in the same page. Does anyone know where I have messed up?

Answer 1

You have an error on the Model Album. It could have the following change:
$inputFilter->add([
'name' => 'id',
'required' => true,
'filters' => [
['name' => ToInt::class],
],
]);
