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) {
$view->with('series_list',Series::all());
});
}
/**
* Register the application services.
*
* @return void
*/
public function register()
{
//
}
}
2)注册提供商
App\Providers\ViewComposerServiceProvider::class,
3)并在模板上回显变量
{!! var_dump($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 \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,有点短
class AppServiceProvider extends ServiceProvider
{
// other methods
public function boot()
{
$series = Series::all();
view()->share('series_list',$series);
}
// other methods
}
