Route::get('/register','ViewController@register');
Route::post('sisreg','SistemController@register');
Route::get('test',function(){
  return view('login.test');
});
//filter
Route::group(array('middleware'=>'auth'),function(){
  Route::get('menu','ViewController@menu');
  Route::get('logout','SistemController@logout');
  Route::post('sispem','SistemController@addpembayaran');
  Route::get('datpem','SistemController@readpembayaran');
  Route::get('del/{id}','SistemController@HapusPelanggan');
  Route::get('pelanggan/{id}','ViewController@pelanggan');
  Route::post('sispel','SistemController@addpelanggan');
  Route::get('datpel/{id}','SistemController@readpelanggan');
});
