php - 如何在 Laravel 中获取和更新数据

Question

所以，我有两个领域。在第一个字段中我想添加旧数据，在第二个字段中我想添加新数据，在这些字段下方是一个按钮，单击该按钮将从 Mongo Table 中获取数据并更新其中的数据。我尝试过实现各种逻辑，但仍然没有运气。任何形式的帮助将不胜感激。

这是我的控制器代码：

public function updatedockets($dockets){
    if (!Session::has('user_id')){
        return Redirect::to('/login');
    }
    $cart = \App\Models\Cart::where('tracking_no',$dockets)->get()->toArray();
    foreach ($cart as $value) {
        $cart = \App\Models\Cart::where('tracking_no')->update(['tracking_no' => $dockets]);
     }   
 }

这是我的视图代码：

<div role="tabpanel" class="tab-pane" id="docket-replace">
                    <form method="post" id="frmDocket" action="/admin/viewdockets">
                    {!! csrf_field() !!}
                    <div>
                        <div class="form-group">
                            <textarea id="txtreploaceDockets" name="replacedockets" class="form-control" rows="15" placeholder="Enter old docket(s) here. Don't put more than 1000 docket numbers, all dockets should be comma(,) or new line separated"></textarea>
                        </div>
                    </div>
                    </form> 

                    <form method="post" id="frmDocket" action="/admin/viewdockets">
                    {!! csrf_field() !!}
                    <div>
                        <div class="form-group">
                            <textarea id="txtreplaceDockets" name="replacedockets" class="form-control" rows="15" placeholder="Enter new docket(s) here. Don't put more than 1000 docket numbers, all dockets should be comma(,) or new line separated"></textarea>
                        </div>
                        <div class="form-group">
                            <div class="text-right pr-sm-15 pb-sm-15">
                                <button type="button" class="btn btn-primary btn-xs" id="btnReplaceDocketData"  onclick="return confirm('Are you sure that you have entered the right docket number?')"> Replace Docket </button>
                            </div>
                        </div>
                    </div>
                    </form>

                </div>

样本：

$course->statuses()->updateOrCreate(
    ['status_id' => $id],
    ['status' => $request->get('status'), 'status_type' => Course::class]
);`
