多个参数传递把 Laravel 5 的控制器
问题说明
在我的应用程序中，用户可以提醒另一个用户有关活动邀请的信息.为此，我需要传递事件 ID 和要邀请的用户的 ID.
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.
在我的路由文件中，我有:
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 = $invitee->id) )!!}
在我的控制器中，我有:
In my controller, I have:
public function remindHelper($eventid, $userid)
{
$event = Events::findOrFail($eventid);
$user = User::findOrFail($userid);
$invitees = $this->user->friendsOfMine;
$invited = $event->helpers;
$groups = $this->user->groupOwner()->get();
return view('events.invite_groups', compact('event', 'invitees', 'invited', 'groups'));
}
但是，当我到达该路线时，收到以下错误:
However, when I hit that route, I receive the following error:
Missing argument 2 for AppHttpControllersEventsController::remindHelper()
我确定我的视图中存在格式错误，但我一直无法对其进行诊断.有没有更有效的方法将多个参数传递给控制器?
I'm sure I have a formatting error in my view, but I've been unable to diagnose it. Is there a more efficient way to pass multiple arguments to a controller?
正确答案
当你定义这个路由时:
Route::get('events/{id}/remind', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);
您是说将向该方法传递单个 URI 参数.
You are saying that a single URI argument will be passed to the method.
尝试传递两个参数，例如:
Try passing the two arguments, like:
Route::get('events/{event}/remind/{user}', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);
查看:
route('remindHelper',['event'=>$eventId,'user'=>$userId]);
