getClientOriginalName（）未定义的方法

标签： php symfony doctrine vichuploaderbundle

我正在一个symfony3项目中工作，我有一个与VICH UPLOADER一起上传多个文件的关系，并将每个文件保存为独立的实体。

第一个实体是＆＃34; Message＆＃34;，与＆＃34; MessageAttachment＆＃34;有一个关系。

消息实体 

 image = StructBlock([
        ('file', ImageChooserBlock()),
        ('caption', RichTextBlock( classname='caption'  )),

    ])

MessageAttachment实体： 

/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var CourseEdition
 *
 * @ORM\ManyToOne(targetEntity="AppBundle\Entity\CourseEdition")

    $this->recipients->removeElement($recipient);

    return $this;
}

/**

public function getRecipients()
{
    return $this->recipients;
}

**正如您所看到的，在MessageAttachments中的setFile（）中，我试图检索原始文件名，并保存它。 Vich上传器可以使用注释来完成，但我不能在php 7中工作！

除了保存原始名称外，一切正常，文件大小和mimetypes正确保存。**

这是symfony向我显示的错误：

[Tue Oct 17 11：58：19.031167 2017] [：error] [pid 9076：tid 1816] [client 127.0.0.1:53731] PHP致命错误：调用未定义的方法Symfony \ Component \ HttpFoundation \ File \ File :: getClientOriginalName（）位于第121行的C：\ xampp \ htdocs \ mindway2 \ src \ AppBundle \ Entity \ MessageAttachment.php，引用者：http://mindway.dev/messages/new

有什么想法吗？我找不到原因！

需要显示真实的文件名，我需要它来重命名文件以供下载。

最后，我决定以持有人的实体之前的方式在控制器中执行此操作：

答案 0 :(得分：1)

它说它正在查看Symfony \ Component \ HttpFoundation \ File \ 文件，并且它在该类中不存在 - 这是真的。 getClientOriginalName方法位于Symfony \ Component \ HttpFoundation \ File \ UploadedFile 中。

您的使用声明是说文件还是UploadedFile？如果它不是UploadedFile，请更改它，看看会发生什么。
