Passing multiple parameters to controller in Laravel 5
提问by Cameron Scott
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，我需要传递事件的 ID 和要邀请的用户的 ID。
In my route file, I have:
在我的路线文件中，我有：
Route::get('events/{id}/remind', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);
In my view, I have:
在我看来，我有：
{!!link_to_route('remindHelper', 'Remind User', $parameters = array($eventid = $event->id, $userid = $invitee->id) )!!}
In my controller, I have:
在我的控制器中，我有：
public function remindHelper($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:
但是，当我到达该路线时，收到以下错误：
Missing argument 2 for App\Http\Controllers\EventsController::remindHelper()
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?
我确定我认为我有格式错误，但我一直无法诊断它。有没有更有效的方法将多个参数传递给控制器？

When you define this route:
当您定义此路由时：
Route::get('events/{id}/remind', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);
You are saying that a single URI argument will be passed to the method.
您是说将单个 URI 参数传递给该方法。
Try passing the two arguments, like:
尝试传递两个参数，例如：
Route::get('events/{event}/remind/{user}', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);
View:
看法：
route('remindHelper',['event'=>$eventId,'user'=>$userId]);

Route:
路线:
Route::get('warden/building/{buildingId}/employee/{employeeId}',[
'uses'=>'WardenController@deleteWarden',
'as'=>'delete-warden'
]);
View:
查看：
<a href="{{route('delete-building',[$building->id])}}"></a>
Controller:
控制器：
public function deleteWarden($buildingId,$employeeId){
$building = Building::find($buildingId);
$building->employees()->detach($employeeId);
return redirect('warden/assign/'.$buildingId)->with('message','Warden Detached successfully');
}

Go to your controller and write code like following:
转到您的控制器并编写如下代码：
public function passData()
{
$comboCoder=['Bappy','Sanjid','Rana','Tuhin'];
$ffi=['Faisal','Sanjid','Babul','Quiyum','Tusar','Fahim'];
$classRoom=['Sanjid','Tamanna','Liza'];
return view('hyper.passData',compact('comboCoder','ffi','classRoom'));
}
/*
Again, in View part use:
(passData.blade.php)
*/
<u>Combocoder:</u>
@foreach($comboCoder as $c)
{{$c}}<br>
@endforeach
<u>FFI</u>
@foreach($ffi as $f)
{{$f}}<br>
@endforeach
<u>Class Room </u>
@foreach($classRoom as $cr)
{{$cr}}<br>
@endforeach
