it prints 'not admin' so what happen to the session , if i prints the admin session in class checkLogin it prints normally

Answer 1

Since L5.3, you cannot a access to the session in the controller's constructor. You have to use a closure :
public function __construct()
{
$this->middleware(function ($request, $next) {
echo Session::has('admin') ? 'admin' : 'not admin';
return $next($request);
});
}

Answer 2

you have to use laravel flashed-session-data
https://laravel.com/docs/5.4/redirects#redirecting-with-flashed-session-data
return redirect('mtest2')->with('admin','yes');
so modify your code like this
class AdminController extends Controller {
public function checkLogin(Request $request){
return redirect('mobiles')->with('admin',true);
}
}
class MobilesController extends Controller {
public function __construct() {
if( session()->has('admin') ){
dd('admin');
}else{
dd('not admin');
}
}
}
Here is updated code if you do not want to use Flashed data
class AdminController extends Controller {
public function checkLogin(Request $request){
$request->session()->put('admin',true);
return redirect('mobiles');
}
}
it should work.
