      </div>
      <!-- /.row -->
    </section>

@endsection    

我的 Controller 是

public function getUpdate($id) {
        $divisions = Division::all();

        $profile = Auth::user();
        $doctor=Doctor::find($id);

        // $post = Post::find($post_id);
        // if(!$post) {
        //     return redirect()->route('blog.index')->with(['fail' => 'Post Not Found']);
        // }
        return view('admin.article.edit')
        ->with('divisions',$divisions)
        ->with('profile',$profile)
        ->with('doctor',$doctor);
    }

    public function postUpdate(Request $request ) {

        $this->validate($request, [
            'name' => 'required|max:120',
            'fee' => 'required|max:5',
            'division_id' => '',
            'district_id' => '',
            'dcategory_id' => '',
            'education' => '',
            'institute' => '',
            'specialty' => '',
            'hospital' => '',
            'time' => '',
            'phone' => ''

            ]);

        $doctor = Doctor::find($request['id']);
        $doctor->name = $request['name'];
        $doctor->division_id = $request['division_id'];
        $doctor->district_id = $request['district_id'];
        $doctor->dcategory_id = $request['dcategory_id'];
        $doctor->institute = $request['institute'];
        $doctor->education = $request['education'];
        $doctor->specialty = $request['specialty'];
        $doctor->hospital = $request['hospital'];
        $doctor->phone = $request['phone'];
        $doctor->time = $request['time'];
        $doctor->fee = $request['fee'];

        // $file = Input::file('pic');
        // $img = Image::make($request->file('pic')->getRealPath());
        // //$img = Image::make($file);
        // Response::make($img->encode('jpeg'));

        // $doctor->pic = $img;
        $doctor->update();

        return redirect()->route('profile')->with(['success' => 'Profile Successfully Updated']);

    }

请帮我解决这个问题。提前致谢

<select>应该有name=""标签。尝试添加<select name="division_id">
