未定义的变量即使定义了 Laravel

Question

所以我得到这个错误 Undefined variable: games 即使我的变量是在控制器中定义的：

我的控制器：

 public function openingPage($id) {

      $this->getCaseData($id);

      $this->getGames();

      return view('caseopener', ['cases' => $this->data])->with('games',$games);;

    }

    private function getCaseData($id) {

        $items = DB::table('cases')->where('id', $id)->get();

        $data = @$items[0] ? $items[0] : array();

        if(isset($data->items)) {

            $data->items = json_decode($data->items, true);

        }

        $this->data = $data;

    }

   private function getGames() {

      $games = array();

      foreach ($this->data->items as $item) {

          $game = new Game($item);

          $games[] = array(

            'id' => $game->id,

            'name' => $game->name,

            'image' => $game->image,

          );

      }

      return $games;

  }

问题似乎来自 getGames() 函数

我的刀片：

@for ($i = 0; $i < 10; $i++)

                      <div class="item" style="background-image:url({{ $games->image }})">

            </div>

          @endfor

如果需要，这里是我的模型“游戏”，用于该 getGames() 函数

class Game extends Model

{

  private $id;

  public $data;

  public function __construct($id) {

       parent::__construct();

       $this->id = $id;

       $this->data = $this->getData();

   }

   private function getData() {

       $game = DB::table('products')->where('id', $this->id)->first();

       if(empty($game)) return array();

       return $game;

   }

}

Answer 1

你忘了分配$gamesin openingPage()，试试这个：public function openingPage($id) {&nbsp; &nbsp; &nbsp;$this->getCaseData($id);&nbsp; &nbsp; &nbsp;$games = $this->getGames();&nbsp; &nbsp; &nbsp;return view('caseopener', ['cases' => $this->data])->with('games',$games);;}

Answer 2

您忘记将游戏分配给$games变量。此外，输出值时有一个错误：$games->image应该是$games[$i]['image']。（访问特定游戏并获取image值作为数组值）如果将来有可能会有多于或少于 10 场比赛，我会将for循环替换为foreach：@foreach($games in $game)&nbsp; &nbsp; <div class="item" style="background-image:url({{ $game['image'] }})">&nbsp; &nbsp; </div>@endforeach
