上传图片时返回 null Laravel 7

Question

我想上传我的照片，但是当我用 dd() 检查时它会 return 空值。

dd($request->file('profile_image'));

但是当我检查

dd($request->all());

我的控制器

public function update(Request $request)
    {
        $time_date = \Carbon\Carbon::now()->toDateTimeString();
        $user = Auth::user();
        dd($request->all());
        dd($request->file('profile_image'));
        if($user->role_id =='1'){
            if($request->hasFile('profile_image')){
                $file = $request->file('profile_image');
                $extension = $file->getClientOriginalExtension();
                $filename = $request->id.'.'.$extension;
                $file->move(public_path($file->getClientOriginalName()),public_path('user/'.$filename));
                $file->save();
            }
            $id = $request->input('id');
            $data_user = User::find($id);
            $data_user->id = $request->input('id');
            $data_user->nama_lengkap = $request->input('name');
            $data_user->email = $request->input('email');
            $data_user->password = $request->input('password');
            $data_user->gender = $request->input('gender');
            $data_user->last_modified_by = Auth::user()->nama_lengkap;
            $data_user->last_modified_time = $time_date;
            $data_user->save();

            return redirect('/indexadmin')->with('Berhasil Edit','Berhasil Edit');
        }
        elseif($user->role_id =='2'){
            return redirect('/indexuser');
        }
        
    }

有什么解决办法吗？

*文件未移动到 public/user 或 storage/public。

Answer 1

试试这个

$file->move(public_path(public_path('user/'.$filename),$file->getClientOriginalName()));

Answer 2

有拼写错误请更正

因为您的 dd($request->all()) 显示您的变量名称是 profil_image

改变

dd($request->file('profile_image');

到

dd($request->file('profil_image');

并且在文件保存代码也更改如下

 if($request->hasFile('profil_image')){
            $file = $request->file('profil_image');
            $extension = $file->getClientOriginalExtension();
            $filename = $request->id.'.'.$extension;
            $file->move(public_path($file->getClientOriginalName()),public_path('user/'.$filename));
            $file->save();
        }
