Redirect back to same page (with variables) on form submit in Laravel 5
提问by user3489502
On my page events.index, I first display a list of events for the logged on user.
在我的页面 events.index 上，我首先显示登录用户的事件列表。
On my index page I have a form with option/select to let the user select and display the events of another user. When he submits that form, I would like my index function (controller) to use the $user_id value (from the form) and display the events.index page again, but for events of that selected user.
在我的索引页面上，我有一个带有选项/选择的表单，让用户选择并显示另一个用户的事件。当他提交该表单时，我希望我的索引函数（控制器）使用 $user_id 值（来自表单）并再次显示 events.index 页面，但对于所选用户的事件。
I'm not sure what would be the best approach:
我不确定最好的方法是什么：
- Set a session variable to keep the user_id value? Not sure how to do that with a form.
- Submit the form with a get method (and get an ugly ?user_id=1 URL)
- Change my index route to accept the post method (although I already have that post/events route taken (by Route::post('events', 'EventsController@store'))
- 设置会话变量以保留 user_id 值？不知道如何用表格来做到这一点。
- 使用 get 方法提交表单（并获得一个丑陋的 ?user_id=1 URL）
- 更改我的索引路由以接受 post 方法（尽管我已经采用了 post/events 路由（通过 Route::post('events', 'EventsController@store')）
Not sure what would be a clean way to do this:
不知道这样做的干净方法是什么：
My route for events/index:
我的事件/索引路线：
Route::get('events', [
'as' => 'event.index',
'uses' => 'EventsController@index'
]);
Events Controller
事件控制器
public function index()
{
// How to get the $user_id value from form?
if (empty($user_id))
{
$user_id = \Auth::user()->id;
}
$events = Event::where('events.user_id','=','$user_id');
$users = User::all();
return view('events.index')->with(['events' => $events])->with(['users' => $users]);
}
View for index
查看索引
{!! Form::open(['route' => 'events.index', 'method' => 'get']) !!}
<select id="user_id" name="user_id">
@foreach($users as $user)
<option value="{{$user->id}}">{{$user->name}}</option>
@endforeach
</select>
{!! Form::submit('Show events for this user') !!}
{!! Form::close() !!}
@foreach($events as $event)
...
@endforeach

You can get the user_idfrom a Requestobject, you just need to inject it in the index method:
你可以user_id从一个Request对象中获取，你只需要在 index 方法中注入它：
public function index(Request $request)
{
$user_id = $request->get('user_id') ?: Auth::id();
$events = Event::where('events.user_id','=','$user_id')->get();
$users = User::all();
return view('events.index')->with(['events' => $events])->with(['users' => $users]);
}
