Class LoginController extends BaseController {

    public function getIndex(){
        return View::make('login',array('eventname' => Request::segment(1)));
    }

    public function postIndex(){

        $xx = User::where('email','=',Input::get('email'))->where('event',$requestedevent)->first();
        $eventattempt = Input::get('event');

        if ($xx){

                if(Auth::attempt($userDetails)){
                    if(Auth::check()){
                        // return var_dump($xx->id);
                        Session::put('username',Auth::user()->name);
                        Session::put('userid',Auth::user()->id);
                        Session::put('event',Auth::user()->event);
                        return Redirect::to($eventattempt.'/form/page1');
                    }
                } else {
                    return Redirect::to($eventattempt.'/login')->with('login_errors',true);
                }

        } else {
            return Redirect::to($eventattempt.'/login')->with('login_errors',true);
        }


    }

}

然后我在这样的Form控制器中做一个过滤器

<?PHP



Class FormController extends BaseController{



    public function __construct(){
        $this->beforeFilter('auth');
        $this->beforeFilter('eventcheck');


    }

  }

而我的filters.PHP看起来像这样

/*
|--------------------------------------------------------------------------
| Application & Route Filters
|--------------------------------------------------------------------------
|
| Below you will find the "before" and "after" events for the application
| which may be used to do any work before or after a request into your

|
*/

App::before(function($request)
{
    //
});


App::after(function($request,$response)
{
    //
});

/*

*/

Route::filter('auth',function()
{
       //dd('ssss');

    if (Auth::guest()){

        if (Request::ajax())
        {
            return Response::make('Unauthorized',401);
        }
        else
        {
            dd(Session::get('event'));

            return Redirect::guest('login');
        }
    }
});


Route::filter('auth.basic',function()
{
    return Auth::basic();
});


/*

|

|
*/

Route::filter('guest',function()
{
    if (Auth::check()) return Redirect::to('/');
});


/*

Route::filter('csrf',function()
{
    if (Session::token() != Input::get('_token'))
    {
        throw new Illuminate\Session\TokenMismatchException;
    }
});


Route::filter('eventcheck',function(){

    //dd(Session::get('event'));

    switch(Request::segment(1))
    {
        case 'rescom_summit_bangalore_2016':
            $requestedevent = 'Rescom Summit Bangalore 2016';
            break;
        case 'design_mission_saudi_arabia_2016':
            $requestedevent = 'Design Mission Saudi Arabia 2016';
            break;
        case 'design_mission_north_east_2016':
            $requestedevent = 'Design Mission North East 2016';
            break;
        case 'design_mission_south_west_2016':
            $requestedevent = 'Design Mission South West 2016';
            break;
        case 'design_mission_middle_east_2016':
            $requestedevent = 'Design Mission Middle East 2016';
            break;
        case 'design_mission_south_africa_2016':
            $requestedevent = 'Design Mission South Africa 2016';
            break;
        case 'design_mission_turkey_2016':
            $requestedevent = 'Design Mission Turkey 2016';
            break;
        case 'design_mission_asia_2016':
            $requestedevent = 'Design Mission Asia 2016';
            break;
        case 'design_mission_russia_2016':
            $requestedevent = 'Design Mission Russia 2016';
            break;
        case 'healthscape_series_2016':
            $requestedevent = 'Healthscape Series 2016';
            break;
        case 'hotelier_summit_africa_2016':
            $requestedevent = 'Hotelier Summit Africa 2016';
            break;
        case 'design_mission_middle_east_2016':
            $requestedevent = 'Design Mission Middle East 2016';
            break;
        case 'hotelier_summit_india_0se_2016':
            $requestedevent = 'Hotelier Summit India Ose 2016';
            break; 
        case 'hotelier_summit_india_Ffe_2016':
            $requestedevent = 'Hotelier Summit India Ffe 2016';
            break;

    }

    if ($requestedevent!=Auth::User()->event){
        Auth::logout();
        Session::flush();
        return Redirect::to(Request::segment(1).'/login')->with('login_errors',true);
    }
});

所以我在登录后尝试打印Session :: get(‘event’)变量时,它在我的生产服务器中显示为NULL,但不在我的本地服务器中

任何想法为什么会发生这种情况
