在 Laravel 5 中将多个参数传递给控制器

In my application, a user has the ability to remind another user about an event invitation. To do that, I need to pass both the IDs of the event, and of the user to be invited.

In my route file, I have:

Route::get('events/{id}/remind', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);

在我看来，我有:

{!!link_to_route('remindHelper', 'Remind User', $parameters = array($eventid = $event->id, $userid = $invitee->id) )!!}

在我的控制器中，我有:

    public function remindHelper($eventid, $userid)
{
    $event = Events::findOrFail($eventid);
    $user = User::findOrFail($userid);
    $invitees = $this->user->friendsOfMine;
    $invited = $event->helpers;
    $groups = $this->user->groupOwner()->get();
    return view('events.invite_groups', compact('event', 'invitees', 'invited', 'groups'));
}

However, when I hit that route, I receive the following error:

Missing argument 2 for App\Http\Controllers\EventsController::remindHelper()

我确信我的视图中有格式错误，但我一直无法诊断它.是否有更有效的方式将多个参数传递给控制器？
