SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'title'
cannot be null
this is my form and fieldset
use Zend\Form\Fieldset;
use Doctrine\Common\Persistence\ObjectManager;
use DoctrineModule\Persistence\ObjectManagerAwareInterface;
use BusinessGhana\Entity\Autos;
class AddFieldset extends Fieldset
{
protected $objectManager;
public function init()
{
$this->add([
'type' => 'text',
'name' => 'title',
'attributes' => [
'id' => 'autoTitle'
],
'options' => [
'label' => 'Title',
'display_empty_item' => true,
'empty_item_label' => 'Maximum of 60 characters',
],
]);
$this->add([
'type' => 'textarea',
'name' => 'description',
'attributes' => [
'id' => 'autoDescription'
],
'options' => [
'label' => 'Description',
'display_empty_item' => true,
'empty_item_label' => 'description',
],
]);
$this->add([
'type' => 'radio',
'name' => 'featured',
'attributes' => [
'id' => 'autoFeatured'
],
'options' => array(
'label' => 'Featured',
'value_options' => array(
array('value' => '0',
'label' => 'No',
'selected' => true,
'label_attributes' => array(
'class' => 'col-sm-2 btn btn-default',
),
),
array(

'class' => 'col-sm-2 btn btn-danger',
),
),
),
'column-size' => 'sm-12',
'label_attributes' => array(
'class' => 'col-sm-2',
),
),
]);
}
}
use Zend\Form\Form;
//use Zend\InputFilter\InputFilter;
class AddForm extends Form
{
public function init()
{
$this->add([
'name' => 'dependentForm',
'type' => AddFieldset::class,
]);
$this->add([
'type' => 'submit',
'name' => 'submit',
'attributes' => [
'value' => 'Submit',
],
]);
}
}
This is my controller action
public function addAction()
{
// Create the form.
$form = new PostForm();
if ($this->getRequest()->isPost()) {
// Get POST data.
$data = $this->params()->fromPost();
// Fill form with data.
$form->setData($data);
if ($form->isValid()) {
// Get validated form data.
$data = $form->getData();
$this->AutosManager->addNewAutos($data);
return $this->redirect()->toRoute('retrieve');
}
}
return new ViewModel([
'form' => $form
]);
}
I know hydration can solve this problem but I don't know how to use it yet.
thanks for any help.
this is my autosManager
class AutosManager
{
/**
* Entity manager.
* #var Doctrine\ORM\EntityManager;
*/
private $entityManager;
/**
* Constructor.
*/
public function __construct($entityManager)
{
$this->entityManager = $entityManager;
}
public function addNewAutos($data)
{
$autos = new Autos();
$autos->setTitle($data['title']);
$autos->setDescription($data['description']);
$autos->setFeatured($data['featured']);
$currentDate = date('Y-m-d H:i:s');
$autos->setDateCreated($currentDate);
$this->entityManager->persist($autos);
$this->entityManager->flush();
}
}
i can retrieve data from database.
This is where i render my forms:
$form = $this->form;
$fieldset = $form->get('dependentForm');
$title = $fieldset->get('title');
$title->setAttribute('class', 'form-control');
$title->setAttribute('placeholder', 'Maximum of 60 characters');
$title->setAttribute('id', 'autoTitle');
$description = $fieldset->get('description');
$description->setAttribute('class', 'form-control');
$description->setAttribute('placeholder', 'Description here...');
$description->setAttribute('id', 'autoDescription');
$featured = $fieldset->get('featured');
$featured->setAttribute('id', 'autoRadio');
$form->get('submit')->setAttributes(['class'=>'btn btn-primary']);
$form->prepare();
echo $this->form()->openTag($form);
?>
<fieldset>
<div class="form-group">
<?= $this->formLabel($title) ?>
<?= $this->formElement($title) ?>
<?= $this->formElementErrors()->render($title,['class'=>'help-block'])?>
</div>
<div class="form-group">
<?= $this->formLabel($description) ?>
<?= $this->formElement($description) ?>
<?=$this->formElementErrors()->render($description,
['class'=>'help-block'])?>
</div>
<div class="form-group">
<?= $this->formLabel($featured) ?>
<?= $this->formElement($featured) ?>
<?= $this->formElementErrors()->render($featured,
['class' =>'help-block']) ?>
</div>
</div></div><div class="row">
<div class="col-md-4">
</fieldset>
<?= $this->formElement($form->get('submit')); ?>

Answer 1

In your function addNewAutos($data) : your $data variable don't have title, description and featured fields. So php consider these as null, and your $this->entityManager->flush() will try to write null values in database, but you have a constraint that at least title must not be null.
So check your $data array contains the title, description and featured fields before to initiate your Auto object...
