Question

我正在使用公交订票系统，我试图将预订的座位详细信息传递给刀片，但是我无法传递值

收集：

public function booking(Request $request)
    {
        //river is used to pass important params with flow of it from page to page
        $seat         = $request->seat;
        $buses_id     = $request->buses_id;
        $schedules_id = $request->schedules_id;
        $data         = Buses::where('buses_id', $buses_id)->first();
        $seat         = json_decode($data->seat_layout, true);
        $front        = json_decode($data->front_layout, true);
        $bookingSeat  = Bookings::whereColumn('schedules_id', 'schedules_id')->get();

        $bookingSeat = $bookingSeat->map(function ($bookSeat) {
            $bookSeat->seat = explode(",", $bookSeat->seat);
            return $bookSeat;
        });

        return view('frontend.booking', ['seat' => $seat, 'buses_id' => $buses_id, 'schedules_id' => $schedules_id, 'front' => $front, 'bookingSeet' => $bookingSeat]);

    }

blade.php

<div class="bus">
@foreach($seat as $key => $item)
@foreach($bookingSeet as $seer)
   <div class="col-md-1">
   <div class="seats back seats 
   @if(in_array($item['name'], $seer['seat']))
   activeSeat
   @endif"
   data-id="{{$key}}">
   <div class="special-attributes"></div>
   @if(isset($item['name'])){{$item['name']}}@else 11A @endif

   <input type="checkbox" name="seat_id[]" id="{{$key}}" value="{{$key}}">

   </div>
   </div>
@endforeach
@endforeach
</div>

在这里，我正在使用两个froeach第一个：@foreach($seat as $key => $item)第二个：@foreach($bookingSeet as $seer)

在这里，第1个座位的所有座位都来自bus table，这个座位有49个座位。

第二个座位已预订，该座位来自booking table，然后与第一个座位核对，然后显示所有已预订的座位

预订表：

bookings_id users_id schedules_id buses_id routes_id seat price profile
    1           1         6           1       3        1  Null  pending
    2           1         6           1       3        2  Null  booked
    3           1         6           1       3        3  null  booked

问题：问题是，当我booking table的刀片中有3行时，如果我有4行，那么我的刀片显示为bus table seats = 49*3 = booking table no of rows，则49 * 4

bookingseet数组

Collection {#418 ▼
  #items: array:3 [▼
    0 => Bookings {#432 ▶}
    1 => Bookings {#433 ▶}
    2 => Bookings {#434 ▶}
  ]
}

预订看到一个这样的数组

Collection {#418 ▼
  #items: array:3 [▼
    0 => Bookings {#432 ▼
      #fillable: array:7 [▼
        0 => "buses_id"
        1 => "users_id"
        2 => "schedules_id"
        3 => "routes_id"
        4 => "seat"
        5 => "price"
        6 => "profile"
      ]
      #primaryKey: "bookings_id"
      #connection: "mysql"
      #table: null
      #keyType: "int"
      +incrementing: true
      #with: []
      #withCount: []
      #perPage: 15
      +exists: true
      +wasRecentlyCreated: false
      #attributes: array:10 [▼
        "bookings_id" => 1
        "users_id" => 1
        "schedules_id" => 6
        "buses_id" => 1
        "routes_id" => 3
        "seat" => array:1 [▼
          0 => "1"
        ]
        "price" => null
        "profile" => "pending"
        "created_at" => "2019-04-09 00:00:00"
        "updated_at" => "2019-04-09 00:00:00"
      ]
      #original: array:10 [▶]
    }

我真的很坚持，请帮助我。我真的不知道如何描述我的问题。

问题在于您的第二个foreach正在复制行。

尝试将第二个foreach约束在需要的地方。

@foreach($seat as $key => $item)

   <div class="col-md-1">
   <div class="seats back seats 
   @foreach($bookingSeet as $seer)
      @if(in_array($item['name'], $seer['seat']))
      activeSeat
      @endif"
   @endforeach
   data-id="{{$key}}">
   <div class="special-attributes"></div>
   @if(isset($item['name'])){{$item['name']}}@else 11A @endif

   <input type="checkbox" name="seat_id[]" id="{{$key}}" value="{{$key}}">

   </div>
   </div>
@endforeach
