在 Laravel 5 中将多个参数传递给控制器

Question

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，我需要同时传递活动的 ID 和要邀请的用户的 ID。

在我的路由文件中，我有：

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'));
}

但是，当我到达那条路线时，收到以下错误：

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

我确定我的观点存在格式错误，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？

Answer 1

当您定义这条路线时：

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

你说的是单个 URI 参数将传递给该方法。

尝试传递两个参数，例如：

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

查看：

route('remindHelper',['event'=>$eventId,'user'=>$userId]);

Answer 2

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

路线 :

Route::get('warden/building/{buildingId}/employee/{employeeId}',[
    'uses'=>'WardenController@deleteWarden',
    'as'=>'delete-warden'
]);

查看 :

<a href="{{route('delete-warden',[$building->id])}}"></a>

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');

}

Answer 4

Route::get('/details/{id}/{id1}/{id2}', 'HomeController@SearchDetails');

//pass data like the below code

<a href="{{url("/details/{$orga_list->dcode}/{$orga_list->dname}/{$GroupHead}")}}" 
target="_blank" > Details </a>

//controller write like the below code

public function SearchDetails($id, $searchtext,$grp_searchtext)  
{
// get data like the below code

$data['searchtext'] = $searchtext;
$data['grp_searchtext'] = $grp_searchtext;
$data['id_is'] = $id;
}

Answer 5

你是这样做的：

<a href="{{route('route.name',['param1'=>$variable1,'param2'=>$variable2])}}">Click Here</a>
