Question

我是laravel的新手。我正在尝试路由到控制器，从模型中获取一些数据并将其传递给视图，如下所示：

class PlayerController extends Controller{

 public function index(){
   $data['start'] = Player::allPlayer()->get();

   return View::make('pages.player')->with($data);
 }
}

现在当我尝试在视图中读取$ data时。它说这是未定义的..

@if (isset($data))
{{'its there'}}
@else
{{'its not there'}}
@endif

我在做错了什么？我试图在控制器中print_r数组。它看起来不错......

您必须通过密钥访问变量：

getData(FullName: string): Promise<PropertyNode[]> {
        let body = JSON.stringify({ FullName });
        let headers = new Headers({ 'Content-Type': 'application/json' });
        let options = new RequestOptions({ headers: headers });

        return this.http.post(this.dataUrl, body, options)
            .toPromise()
            .then(this.extractData)
            .catch(this.handleError);
    }

查看：

class PlayerController extends Controller{

 public function index(){
   $data['start'] = Player::allPlayer()->get();

   return View::make('pages.player')->with($data);
 }
}

即使这应该有效

$post['hello'] = \App\Post::where('id','=',1)->get();
return view('test',compact('post'));

并在视野中

@if($post)
    {{$post['hello']}}
@else
    <p>Oops!</p>
@endif
