Я пытаюсь понять, как сделать несколько загрузок файлов, но без везения. Я не смог получить слишком много информации об этом. Может быть, кто-то здесь поможет мне? : Dsymfony2 image multiple upload
Критерии:
Я знаю, что в моей форме типа я должен использовать мультипликатор для полей; но когда я добавляю его, он дает мне эту ошибку.
Catchable Fatal Error: Argument 1 passed to PhotoGalleryBundle\Entity\Image::setFile() must be an instance of Symfony\Component\HttpFoundation\File\UploadedFile, array given, called in /home/action/workspace/www/DecorInterior/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 442 and defined Image Entity
