Question

我从api返回了json数据，并希望使用Blade进行输出。

 9 => {#670 ▼
    +"id": 10300
    +"name": "Fallout 3: Mothership Zeta"
    +"slug": "fallout-3-mothership-zeta"

    }
  }

我希望得到的是我尝试过的Cover URL，并遍历所有json数据，并将上述10项返回到其中

   @foreach ($game as $games)
                  <div class="col-md-2">
                      <img src="" alt="">
                      <p>{{ $games->name}}</p>
                      @foreach ($games->cover as $cover)
                          <p>{{$cover['url']}}</p>
                      @endforeach
                  </div>
              @endforeach

当前，这就是我循环中的内容，我收到此错误

非法的字符串偏移量'url'

Answer 1

尝试一下：

{{ $arr[9]->id }}
{{ $arr[9]->name }}
{{ $arr[9]->cover->url }}

注意，我假设这是第10个元素的较大数组的名称为$arr。将该名称替换为代码中的名称。

Answer 2

在循环中，将$games更改为$game：

@foreach($games as $game)
    <div class="col-md-2">
        <img src="" alt="">
        <p>{{$game->name}}</p>
        <p>{{$game->cover->url}}</p> 
    </div>
@endforeach

通过嵌套的Json对象Laravel循环出错
