php - 扩展核心并在 Laravel 中显示每个页面中的数据

Question

按照指南，我有

1)创建服务提供者

class ViewComposerServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        view()->composer('template', function ($view) {
            $view->with('series_list', Series::all());
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

2) 注册提供商

 App\Providers\ViewComposerServiceProvider::class,

3) 并回显模板中的变量

{!! var_dump($series_list)  !!}

问题是:

Route::get('/', 'HomeController@index');
Route::get('product/view/{id}', 'ProductController@view');
Route::get('product/detail/{id}', 'ProductController@detail');
Route::get('/page/contact', 'PageController@contact');

PageController 和 HomeController 可以显示 $series_list，但 ProductController 会返回错误:

Undefined variable: series_list in the template

这是产品 Controller :

class ProductController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        //$this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function view($id = 1)
    {
        return view('product/list');
    }

    public function detail($id = 1)
    {
        return view('product/detail');
    }
}

非常感谢您的帮助。

另一种方式，更短一些

class AppServiceProvider extends ServiceProvider
{
    // other methods

    public function boot()
    {
        $series = Series::all();
        view()->share('series_list', $series);
    }

    // other methods

}
