我是Symfony的新手，我很难找到上传多个文件的方法。我正在尝试建立一个应用程序。有公寓，每个公寓可以有多个图像。
公寓(一对多(-图像(多对一(
所以我创建了两个实体，并在我的AppartmentTypeForm中添加了一个名为"image"的字段，它是我的ImageTypeForm中"name"的CollectionType:：class，它是FileType:：class
我添加了一些js，可以通过点击按钮添加多个输入文件
在我提交表格之前，一切都正常，如果我添加了3个图像并尝试，我就无法获得图像名称
$photo = $form->get('image')->getData();
我会看到我的3个数组，只有我公寓的id设置没有名称没有文件什么都没有。
我可能做错了什么，但我不知道在哪里。
控制器，正如您将看到的，iI尝试foreach我的图像数据，但我只能获得文件名的1，即使当我尝试flush((时，Symfony也会返回一个错误，因为它试图设置我的数据库列"name"为null。。。，

这是我时得到的
$image = form->get('image')->getData();
dd($image) return me this

很抱歉有点长，但我试着到处搜索，找不到响应
谢谢。
所以很少编辑：
当我提交我的文件时，我的图像会被重命名并上传到我的uploads_directory中，我不知道如何或为什么。我什么都没改变，但是我怎样才能使我的数据库列名等于我的文件名。
第二次编辑：
我通过更改在数据库中上传了1张图像
$image->setName($newFileName);
$em->persist($image)
通过这个：
$em->persist($image->setName($newFileName));
但我仍然无法将我所有的图像都放入数据库。
将$image = new Image;和$em->persist($image);移动到的前一部分
...
foreach ($form->get('image') as $formChild) {
$image = new Image; // added
$image->setCreatedAt(new DateTime()); // added
$image->setUpdatedAt(new DateTime()); // added
$uploadedImages = $formChild->get('name')->getData();
$uploadedImage = $uploadedImages[0];
$newFileName = $this->handleFile($slugger, $uploadedImage);
$image->setName($newFileName);
$em->persist($image); // added
}
...
