实体编辑表单中的“文件类型”字段

Question

I have a user entity. At registration, a file is required. When I edit this user entity, I want to be able to see the uploaded file and modify it.

I have this form :

$builder->add('email', EmailType::class  , ['label' => 'Adresse mail']);
$builder->add('photo', FileType::class);

Controller :

$form = $this->createForm(ProfilTutoreFormType::class, $user)

Entity :

 /**
 * @var string
 */
protected $email;

 /**
 * @var string
 * @ORM\Column(name="photo", type="string", length=255)
 */
private $photo;

Email field is populated with user's email but photo field stays blank.

First you must copy the file to the system. You should then save the new path to the database. Examine the example here https://symfony.com/doc/current/controller/upload_file.html
