所以我得到這個(gè)錯(cuò)誤 Undefined variable: games 即使我的變量是在控制器中定義的：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 $games; }問(wèn)題似乎來(lái)自 getGames() 函數(shù)我的刀片：@for ($i = 0; $i < 10; $i++) <div class="item" style="background-image:url({{ $games->image }})"> </div> @endfor如果需要，這里是我的模型“游戲”，用于該 getGames() 函數(shù)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; }}

你忘了分配$gamesin openingPage()，試試這個(gè)：
public function openingPage($id) {
$this->getCaseData($id);
$games = $this->getGames();
return view('caseopener', ['cases' => $this->data])->with('games',$games);;
}

您忘記將游戲分配給$games變量。
此外，輸出值時(shí)有一個(gè)錯(cuò)誤：$games->image應(yīng)該是$games[$i]['image']。（訪問(wèn)特定游戲并獲取image值作為數(shù)組值）
如果將來(lái)有可能會(huì)有多于或少于 10 場(chǎng)比賽，我會(huì)將for循環(huán)替換為foreach：
@foreach($games in $game)
<div class="item" style="background-image:url({{ $game['image'] }})">
</div>
@endforeach
