Symfony2: transformationFailure "Bileşik formlar, bir dizi veya NULL gönderiminde bekler."

Question

6 alandan oluşan bir Konum nesnesine sahibim. Bu alanların bazıları isteğe bağlıdır.

Yani ben PRE_SET_DATA ve PRE_SUBMIT olaylara Yer bağlı alanları, doldurmak bir LocationSelectType var. Bu iyi çalışıyor.

Ama PRE_SUBMIT üzerinde

, ben de kullanıcının girdiği verilerden Yer nesnesi oluşturmak istiyoruz. Bu çalışır, ancak sonunda bir hata tetikler gözükmektedir: * transformationFailure "Bileşik şekilleri sunulması üzerine bir dizi veya NULL bekliyoruz." *

class LocationSelectType extends AbstractType {

private $router; 
private $options; 

public function __construct(EntityManager $em,Router $router) 
{ 
    $this->em = $em;

Sorununuz burada

public function onPreSubmit(FormEvent $event) { 
    $form = $event->getForm(); 
    $data = $event->getData(); //find Location that fit the form data 
    $location = $this->em->getRepository('MyWorldBundle:Location')->findLocationFromData($data) ; //populate all relevant geo field to render the form view 
    $this->addGeoFields($form, $location); //replace data with the object location 
    $event->setData($location); 
} 

olduğunu

$event->setData($location); içinde hata yaptınız: pre_submit olayında, $event->getData() ilişkisel bir dizidir, bir varlık değil (bkz. https://symfony.com/doc/current/form/events.html#component-form-event-table), bu nedenle $event->setData() içinde bir ilişkisel dizi belirlemelisiniz. dump($event->getData()) numaralı telefonu arayın ve beklenen biçime bakın.
