Php 多个上传图像easyadmin存在问题

您好，我在easyadmin多图像上传方面有几个问题。请帮忙。奇怪的是，我的问题主要是蛋糕和蛋糕照片。在easyadmin中，我在蛋糕中添加了几个图像，它们被转换为数组并存储在数据库中。在他们被展示出来之后。至少我计划做的是

下面是Cakes.php实体

你可以通过这样做来解决你的问题

 public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('ImageFile', VichFileType::class,array('data_class' =>null))
        ;
    }

Argument 1 passed to App\Entity\CakePhotos::setCake() must be an instance of App\Entity\Cake or null, instance of App\Entity\Cakes given, called in /home/kumaskano1/Desktop/Learning/Symfony/Shirin/src/Entity/Cakes.php

 public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('ImageFile', VichFileType::class,array('data_class' =>null))
        ;
    }
