Laravel：过滤数据后重定向到相同的路由

Question

我有一个索引页面，其中列出了我拥有的所有数据，还有一个简单的过滤表单，可以向其给定路由发出 POST 请求

@section('content')

    <h4>Maçlar</h4>

    <form class="form-inline" method="post" action="{{ route('games.filter') }}">
        {{ csrf_field() }}
        <div class="form-group mb-2">
            <label class="sr-only">Email</label>
            <select class="form-control" id="season-select" name="season">
                <option value="0">Tüm Sezonlar</option>
                @foreach ($seasons as $season)
                    <option value="{{$season->id}}" {{old('season') == $season->id ? 'selected' : ''}}>{{$season->season}}</option>
                @endforeach
            </select>
        </div>
        <div class="form-group mx-sm-3 mb-2">
            <label for="week-select" class="sr-only">Password</label>
            <select class="form-control" id="week-select" name="week">
                <option value="0">Tüm Haftalar</option>
                @foreach ($weeks as $week)
                    <option value="{{$week->id}}" {{old('week') == $week->id ? 'selected' : ''}}>{{$week->week}}</option>
                @endforeach
            </select>
        </div>
        <button type="submit" class="btn btn-primary mb-2">Filtrele</button>
    </form>

    <table class="table table-striped">
        <thead>
        <tr>
            <th scope="col">Sezon</th>
            <th scope="col">Hafta</th>
            <th scope="col">Ev Sahibi Takım</th>
            <th scope="col">Misafir Takım</th>
            <th scope="col">Tarih ve Saat</th>
            <th scope="col">Yer</th>
        </tr>
        </thead>
        <tbody>
        @foreach ($games as $game)
            <tr>
                <td>{{$game->season->season}}</td>
                <td>{{$game->week->week}}</td>
                <td>{{@$game->homeTeam->name}}</td>
                <td>{{@$game->awayTeam->name}}</td>
                <td>{{@$game->game_date_time}}</td>
                <td>{{@$game->place}}</td>
            </tr>
        @endforeach
        </tbody>
    </table>

@endsection

在控制器中我的索引方法如下

public function index()
{
     $seasons = Season::all();
     $weeks = Week::all();
     $games = Game::with('season', 'week', 'homeTeam', 'awayTeam')->get();

     return view('game.index')->with(compact('games', 'seasons', 'weeks'));
}

还有我的过滤器方法，它执行POST 请求并将过滤后的数据传递到与索引使用相同的视图。

public function filter(Request $request)
{
     $seasons = Season::all();
     $weeks = Week::all();

     $games = Game::with('season', 'week', 'homeTeam', 'awayTeam')
                ->when(request('season') != 0, function ($q) {
                    return $q->where('season_id', request('season'));
                })->when(request('week') != 0, function ($q) {
                    return $q->where('week_id', request('week'));
                })
                ->get();

     return view('game.index')->with(compact('games', 'seasons', 'weeks'));
}

我想学习的是，实现这种情况的最佳方法是什么？执行POST 过滤请求后是否可以重定向回相同的索引路由？并且old 方法在刀片模板中不起作用，因此我无法在请求后显示旧表单数据。它可能有什么问题？最后，如何在索引和过滤方法中删除这些重复的行。

$seasons = Season::all();
$weeks = Week::all();

任何帮助将不胜感激。 PS：我不想用 Ajax、Vue.js 等，我想用 Laravel 做。

您也可以在索引方法中使用过滤器。无需为过滤器创建其他方法。

改变看法。

<form class="form-inline" method="post" action="{{ route('games.index') }}"> // form redirect to index method

索引方法的变化。

public function index(Request $request)
{
     $seasons = Season::all();
     $weeks = Week::all();

     if($request->has('season') && $request->has('week') ){ // check filter value is passed or not
      $games = Game::with('season', 'week', 'homeTeam', 'awayTeam')
                ->when(request('season') != 0, function ($q) {
                    return $q->where('season_id', request('season'));
                })->when(request('week') != 0, function ($q) {
                    return $q->where('week_id', request('week'));
                })
                ->get();
     }
     else{
        $games = Game::with('season', 'week', 'homeTeam', 'awayTeam')->get();
     }

     return view('game.index')->with(compact('games', 'seasons', 'weeks'));
}
