Laravel：過濾數據后重定向到同一路由

Question

我有一個索引頁面，其中列出了我擁有的所有數據，還有一個簡單的過濾表單，該表單向其給定的路由發出POST請求

@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'));
}

還有我的過濾器方法，該方法執行POST請求並將經過過濾的數據傳遞到與索引使用相同的視圖。

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'));
}

我想學習的是，實現這種情況的最佳方法是什么？ 執行POST請求進行過濾后，是否可以重定向回相同的索引路由？ 而且old方法在刀片模板中不起作用，因此請求后我無法顯示舊表單數據。 這可能是什么問題？ 最后，如何在索引和過濾器方法中刪除這些重復的行。

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

任何幫助，將不勝感激。 PS：我不想使用Ajax，Vue.js等。我想在Laravel中使用它。

您也可以在索引方法中使用過濾器。 無需創建其他過濾方法。

改變看法。

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

更改索引方法。

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'));
}
