【中文标题】如何使“上传文件”不是必需的 - Laravel 8【英文标题】：How to make "upload file" optional not required - Laravel 8 【发布时间】：2021-08-19 08:37:37 【问题描述】：我试图让用户选择是否要上传文件
这是完整的控制器代码：

我怎样才能使它可以为空？
我已更新问题以包含控制器的完整代码
现在我面对的是“未定义的变量：profile_image_url”
在我按照答案后，我得到了这个错误
【问题讨论】：
使验证规则可以为空，并使用条件来检查请求是否有文件。 制作一个简单的函数来上传文件然后使用它，检查我的回答我希望它对你有用.. 【参考方案1】：您可以使用hasFile查看
$request = request();
if ($request->hasFile('uploadfile'))
$profileImage = $request->file('uploadfile');
$profileImageSaveAsName = time() . "aa" . "-profile." . $profileImage->getClientOriginalExtension();
$upload_path = 'uploads/form1/';
$profile_image_url = $upload_path . $profileImageSaveAsName;
$success = $profileImage->move($upload_path, $profileImageSaveAsName);
参考：https://laravel.com/docs/8.x/requests#retrieving-uploaded-files
更新
根据您的代码，您需要传递 $request
return DB::transaction(function () use ($input)
if (\request()->hasFile('uploadfile'))
$profileImage = \request()->file('uploadfile');
$profileImageSaveAsName = time() . "aa" . "-profile." . $profileImage->getClientOriginalExtension();
$upload_path = 'uploads/form1/';
$profile_image_url = $upload_path . $profileImageSaveAsName;
$success = $profileImage->move($upload_path, $profileImageSaveAsName);
if (\request()->hasFile('uploadfile2'))
$profileImage2 = \request()->file('uploadfile2');
$profileImageSaveAsName2 = time() . "bb" . "-profile." . $profileImage2->getClientOriginalExtension();
$upload_path2 = 'uploads/form1/';
$profile_image_url2 = $upload_path2 . $profileImageSaveAsName2;
$success = $profileImage2->move($upload_path2, $profileImageSaveAsName2);
if (\request()->hasFile('uploadfile3'))
$profileImage3 = \request()->file('uploadfile3');
$profileImageSaveAsName3 = time() . "cc" . "-profile." . $profileImage3->getClientOriginalExtension();
$upload_path3 = 'uploads/form1/';
$profile_image_url3 = $upload_path3 . $profileImageSaveAsName3;
$success = $profileImage3->move($upload_path3, $profileImageSaveAsName3);
if (\request()->hasFile('uploadfile4'))
$profileImage4 = \request()->file('uploadfile4');
$profileImageSaveAsName4 = time() . "dd" . "-profile." . $profileImage4->getClientOriginalExtension();
$upload_path4 = 'uploads/form1/';
$profile_image_url4 = $upload_path4 . $profileImageSaveAsName4;
$success = $profileImage4->move($upload_path4, $profileImageSaveAsName4);
【讨论】：
在我做了你提到的之后，我得到了一个错误“未定义的变量：请求” return DB::transaction(function () use ($input,$request) 在我用你的答案更新代码后，我仍然收到“未定义的变量：请求” 删除请求并在您使用 $request 的任何地方更改为 $input 更新答案。如果您遇到错误请告诉我【参考方案2】：$input = Request::all();
$rules = array(
'name' => 'required|string|max:255',
'usertype' => 'required|string|max:255'
);
$validation = Validator::make($input, $rules, array());
if ($validation->fails())
$message = $validation->messages()->first();
return Response()->json(ResponseManager::getError(null, 1, $message));
DB::beginTransaction();
try
$input['uploadfile1'] = null;
$input['uploadfile2'] = null;
$input['uploadfile3'] = null;
$input['uploadfile4'] = null;
if (Request::hasFile('uploadfile'))
$input['uploadfile1'] = $this->upload_file($input['uploadfile'], 'uploads/form1');
if (Request::hasFile('uploadfile2'))
$input['uploadfile2'] = $this->upload_file($input['uploadfile2'], 'uploads/form1');
if (Request::hasFile('uploadfile3'))
$input['uploadfile3'] = $this->upload_file($input['uploadfile3'], 'uploads/form1');
if (Request::hasFile('uploadfile4'))
$input['uploadfile3'] = $this->upload_file($input['uploadfile4'], 'uploads/form1');
$result = User::create($input);
DB::commit();
$message = 'success';
return Response()->json(ResponseManager::getResult(null, 10, $message));
catch (Exception $e)
DB::rollBack();
$message = $e->getMessage();
return Response()->json(ResponseManager::getError(null, 8, $message));
简单制作一个上传文件的通用函数。
public static function upload_file($image, $store_path)
$name = md5(uniqid(rand(), true)) . str_replace(' ', '-', $image->getClientOriginalName());
$image->move(public_path('/' . $store_path), $name);
return $store_path . '/' . $name;
希望对你有用
【讨论】：
以上是关于如何使“上传文件”不是必需的 - Laravel 8的主要内容，如果未能解决你的问题，请参考以下文章
Laravel 验证 - 数组字段，仅允许两个字段之一，但都不是必需的
Laravel 5.3，检查上传的文件是不是大于upload_max_filesize（可选上传）
Laravel 5.2：测试上传的文件是不是有效：非对象上的 isValid()
