函数参数太少，1 个已通过，正好 2 个预期 - Laravel

Question

我正在尝试创建一个名为promote()的编辑函数，它编辑userData表中的表值。

这是我使用的表格

<form method="post" action="{{action('PromotionsController@promote', $id )}}">

                       {{csrf_field()}}

                       <input type="hidden" name="_method" value="PATCH" />

                       <input type="text" name="rank" class="'form-control" value="{{$rankid}}" readonly />

                       <input type="text" name="id" class="'form-control" value="{{$id}}" readonly />

                       <input type="submit" class="btn btn-primary" value="Promote" />

                      </form>

值 $rankid 和 $id 已放置在表单中并准备提交。这是控制器的末端。

  /**

     * @param \Illuminate\Http\Request $request

     * @param int $id

     * @return \Illuminate\Http\Response

     */

    public function promote(Request $request, $id)

    {

        $this->validate($request, [

            'rank' => 'required',

            'id' => 'required'

    ]);

      $promotion= userData::find($id);

      $promotion->rank = $request->get('rank');

      $promotion->id = $request->get('id');

        $promotion->save();

      return redirect()->route('home');

    }

我收到错误消息 App\Http\Controllers\PromotionsController::promote() 函数参数太少，已通过 1 个，预期有 2 个，有其他方法可以解决此问题吗？

尝试这个 ：首先创建一条这样的路线route::put('/promote/{id}')->name('promote.update');和<form method="post" action="{{route('promote.update',['id' => $id ])}}">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{{csrf_field()}}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<input type="hidden" name="_method" value="PUT" />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<input type="text" name="rank" class="'form-control" value="{{$rankid}}" readonly />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<input type="submit" class="btn btn-primary" value="Promote" />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </form>
