Question

您好我在编辑和更新表单中的数据方面遇到了问题。我已经尝试从表单中获取数据，但是当我尝试编辑和更新它时，它将生成另一个数据。谢谢！

Controller: 
        public function registerPackage()
    {       
        $activity_packages = Chap_activity_packages::all();
        return view('admin.registerPackage',compact('activity_packages'));
    }

    public function savePackage(Request $request)

    {
        $this->validate($request,[
        'chap_activity_packages_name'=>'required|Min:4|unique:chap_activity_packa        ges',
        'chap_activity_packages_price'=>'required|numeric'
        ]);

        $values = $request->all();
        Chap_activity_packages::create($values);
        return view('admin.registerPackage');
    }

    public function editPackage($id)
    { 
        $act = Chap_activity_packages::find($id);
        $activity_packages=Chap_activity_packages::all();

        return view('admin.registerPackage',compact('act','activity_packages'));

    }

                                    </div>
      @stop

这些是控制器和视图的代码。如果出了什么问题，请告诉我。非常感谢！

我没有看到更新控制器中数据的方法，它应该如下所示：

// YourController.php, use implicit route model binding
public function update(App\Chap_activity_packages $model)
{
    // do your validation here
    // $this->validate(blahblahblah...)
    // ...
    $model->update(request()->all());
    return redirect()->back()->with('msg', 'Update success.'); 
}

// routes.php
Route::put('your/route/to/model/{model}', 'YourController@update');

// yourTemplate.blade.php
// remember to use method spoofing
{{ Form::open(['url' => 'your/route/to/model/' . $model->id, 'method' => 'put']) }}

可以找到有关路线模型绑定的信息here。祝你好运！
