【问题描述】：

我需要从 laravel 中的弹出模式更新用户数据，但我做不到。数据库中的一切都保持不变。

我还是 laravel 的新手，而且我的截止日期很紧。这真让我抓狂。我知道我可能只是在做一些愚蠢的事情，但我很难知道它是什么。

当我点击提交按钮更新数据时，没有任何反应。

web.php

/* TEACHERS MATTERS*/
Route::get('timetable/user_id', [TimetableController::class, 'create'])->name('timetable.up');
Route::post('timetable/user_id', [TimetableController::class, 'store']);
Route::get('timetable', [TimetableController::class, 'create']);
Route::post('timetable', [TimetableController::class, 'store']);
Route::Post('timetable/update', [TimetableController::class, 'update'])->name('timetable/update');

在上面，这是路线：

Route::Post('timetable/update', [TimetableController::class, 'update'])->name('timetable/update');

时间表控制器：

 public function update(Request $request)
    
        $timetable = Timetable::find($request->get('id'));
        $timetable['tea_id'] = $request->get('tea_id');
        $timetable['subject'] = $request->get('subject');
        $timetable['class'] = $request->get('class');
        $timetable['day'] = $request->get('day');
        $timetable['start_time'] = $request->get('start_time');
        $timetable['close_time'] = $request->get('close_time');
        $update = $timetable->save();
        if($update)
            return redirect()->back()->with('success', 'New Schedule Created');
        else
            return redirect()->back()->with('failed', 'Update failed');
        
    
    public function status($id, $status)
//        echo $status;
//        dd($id);
        $timetable = Timetable::find($id);
        $timetable['status'] = $status;
        $update = $timetable->save();
        if($update)
            return redirect()->back()->with('success', 'Status changed');
        else
            return redirect()->back()->with('failed', 'Action not performed');
        
    

这是数据库图像：

enter image description here

timeblade.php

  <!-- Start of modal update  -->
                        <div class="modal fade" id="update" tabindex="-1" role="dialog" aria-

                                                    </div>
                                                </center>

                                                <div class="modal-footer">
                                                    <button type="button" class="btn btn-outline-danger" data-dismiss="modal"
                                                        aria-label="Close">Close</button>

                                    </div>
                                </div>
                                <!-- End of modal update -->

【参考方案1】：

您在 Eloquent 模型中使用了数组语法而不是对象语法。 见https://laravel.com/docs/8.x/eloquent#updates

更正：

public function update(Request $request)

    $timetable = Timetable::find($request->get('id'));
    $timetable->tea_id = $request->get('tea_id');
    $timetable->subject = $request->get('subject');
    $timetable->class = $request->get('class');
    $timetable->day = $request->get('day');
    $timetable->start_time = $request->get('start_time');
    $timetable->close_time = $request->get('close_time');
    $update = $timetable->save();
    if($update)
        return redirect()->back()->with('success', 'New Schedule Created');
     else 
        return redirect()->back()->with('failed', 'Update failed');
    

这个 sn-p 缺少验证和一些检查（例如，您应该检查您的模型是否存在于数据库中）
