php – 扩展核心并在Laravel的每个页面中显示数据

按照指南,我有

1)创建服务提供商

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

AppProvidersViewComposerServiceProvider::class,

3)并在模板上回显变量

{!! 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将返回错误：

Undefined variable: series_list in the template

这是ProductController：

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

    /**
     * Show the application dashboard.
     *
     * @return IlluminateHttpResponse
     */
    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.

class AppServiceProvider extends ServiceProvider
{
    // other methods

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

    // other methods

}
