Laravel 图片上传问题

Question

您好，我正在尝试在我的 laravel 应用中上传用户照片，

当用户更新他/她的个人资料时，用户可以添加一个属性。

问题

现在当我运行我当前的代码时，如果用户尝试更新个人资料而不上传照片，它会给我一个错误提示

"在 null 上调用成员函数 extension()"

但是当我尝试上传照片时，照片上传成功但图片名称未存储在数据库中（保存的是空值而不是图片名称）和其他字段不会得到更新。

这是我的用户配置文件更新控制器代码（仅包含功能）

public function update(Request $request, User $setting)
        {

            $changedAttributes = array_diff($request->all(), $setting->getAttributes());

            $validationRules = array_intersect_key([
               'name'      => ['required', 'alpha','min:2', 'max:255'],
               'last_name' => ['required', 'alpha','min:5', 'max:255'],
               'mobile'    => ['required', 'string', 'regex:/\+(9[976]\d|8[987530]\d|6[987]\d|5[90]\d|42\d|3[875]\d|
               2[98654321]\d|9[8543210]|8[6421]|6[6543210]|5[87654321]|
               4[987654310]|3[9643210]|2[70]|7|1)\d{1,14}$/'],
               'email'     => ['required', 'string', 'email', 'max:255', 'unique:users,email,'.$setting->id.''],
               'propic' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
           ], $changedAttributes);

           $imageName = time().'.'.$request->propic->extension();  

           $request->propic->move(public_path('propics'), $imageName);

           $this->validate($request, $validationRules);

           $setting->update($changedAttributes);

           return Redirect::back()->with('success',__('sentence.User updated successfully'));  

        }

下面是我的表格，

<form action="{{ route('settings.update',$user->id) }}" method="POST" enctype="multipart/form-data" >
            <div class="row mt-5">
            <div class="col-sm-3">

Answer 1

尝试替换

$imageName = time().'.'.$request->propic->extension();  

对这些

$imageName = time().'.'.$request->propic->getClientOriginalExtension();  

Answer 2

所以我终于找到了解决上述问题的方法， 我按照下面的说明更改了我的控制器功能，并且没有更改表单，

public function update(Request $request, User $setting)
        {

            $changedAttributes = array_diff($request->all(), $setting->getAttributes());

            $validationRules = array_intersect_key([
               'name'      => ['required', 'alpha','min:2', 'max:255'],
               'last_name' => ['required', 'alpha','min:5', 'max:255'],
               'mobile'    => ['required', 'string','min:10','max:14', 'regex:/\+(9[976]\d|8[987530]\d|6[987]\d|5[90]\d|42\d|3[875]\d|
               2[98654321]\d|9[8543210]|8[6421]|6[6543210]|5[87654321]|
               4[987654310]|3[9643210]|2[70]|7|1)\d{1,14}$/'],
               'email'     => ['required', 'string', 'email', 'max:255', 'unique:users,email,'.$setting->id.''],
               'propic' => ['required','image','mimes:jpeg,png,jpg,gif,svg','max:2048'],
           ], $changedAttributes);

           if($request->hasFile('propic'))
           {
                $this->validate($request, [
                    'name' => ['required', 'alpha','min:2', 'max:255'],
                    'last_name' => ['required', 'alpha','min:5', 'max:255'],
                    'mobile' => ['required', 'string','min:10','max:14', 'regex:/\+(9[976]\d|8[987530]\d|6[987]\d|5[90]\d|42\d|3[875]\d|
                    2[98654321]\d|9[8543210]|8[6421]|6[6543210]|5[87654321]|
                    4[987654310]|3[9643210]|2[70]|7|1)\d{1,14}$/'],
                    'email' => ['required', 'string', 'email', 'max:255', 'unique:users,email,'.$setting->id.''],
                    'propic' => ['required','image','mimes:jpeg,png,jpg,gif,svg','max:2048'],
                ],$request->all());

                $imageName = time().'.'.$request->propic->extension();  
                $request->propic->move(public_path('propics'), $imageName);
                $setting->propic=$imageName;
                $setting->name=$request->input('name');
                $setting->last_name=$request->input('last_name');
                $setting->mobile=$request->input('mobile');
                $setting->email=$request->input('email');
                $setting->update();
                return Redirect::back()->with('success',__('User updated successfully'));  
           }

           $this->validate($request, $validationRules);

           $setting->update($changedAttributes);

           return Redirect::back()->with('success',__('User updated successfully'));  

        }

所以这对我有用。
