我有一個表單類型,並希望知道在我的情況下在setDefaultOptions
對data_class
提出什麼要求。我知道我們通常會放置實體的路徑,但在這種情況下,我嵌入了兩個實體,所以我現在該做什麼?在表單類型中爲data_class賦值
我知道我們可以忽略它,但我不想因爲它建議不由SensioLabs(...So, while not always necessary, it's generally a good idea to explicitly specify the data_class option...)。
$resolver->setDefaults(array('data_class' => '?????????????????????'));
表格類型:
namespace Car\BrandBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class BothType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->setMethod('POST')
->setAction($options['action'])
->add('brands', new BrandsType())
->add('cars', new CarsType())
->add('button', 'submit', array('label' => 'Add'))
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array('data_class' => '?????????????????????'));
}
public function getName()
{
return 'both';
}
}
控制器:
namespace Car\BrandBundle\Controller;
use Car\BrandBundle\Entity\Brands;
use Car\BrandBundle\Entity\Cars;
use Car\BrandBundle\Form\Type\BothType;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class BothController extends Controller
{
public function indexAction()
{
$entity = array(new Brands(), new Cars());
$form = $this->createForm(new BothType(), $entity,
array('action' => $this->generateUrl('bothCreate')));
return $this->render('CarBrandBundle:Default:both.html.twig',
array('page' => 'Both', 'form' => $form->createView()));
}
}
當我回聲提交的數據我得到這個複製的數據:
Array
(
[0] => Car\BrandBundle\Entity\Brands Object
(
[id:protected] =>
[name:protected] =>
[origin:protected] =>
)
[1] => Car\BrandBundle\Entity\Cars Object
(
[id:protected] =>
[model:protected] =>
[price:protected] =>
)
[brands] => Car\BrandBundle\Entity\Brands Object
(
[id:protected] =>
[name:protected] => Mercedes
[origin:protected] => Germany
)
[cars] => Car\BrandBundle\Entity\Cars Object
(
[id:protected] =>
[model:protected] => SL500
[price:protected] => 25,000
)
)
在你的情況下,你沒有一個實體類來映射它。所以除非你創建一個,否則你應該把它留空。 – Chausser
