Question

数据库表如下：

数据库中的“ extras”列存储着一个看起来像这样的对象数组：

[
{"id":92,"product_id":8966,"extra_type":"Extras","extra_name":"Olives"},

{"id":93,"product_id":8966,"extra_type":"Extras","extra_name":"Ketchup"},

{"id":92,"product_id":8966,"extra_type":"Extras","extra_name":"Olives"}
]

下面的代码（来自Laravel刀片）返回对象数组。

@foreach($item->orderedProducts as $op)
<tr>
     <td>
         <span>{{ $op['extras'] }}</span><br>
     </td>
</tr>
@endforeach

$ op返回此：

  "id": 171,
  "product_id": 8966,
  "order_id": 175,
  "price": 11,
  "count": 1,

    }
  }
}

我想要实现的是从“ extras：”中获取“ extra_name”的所有值。

所需的输出应类似于：

橄榄番茄酱橄榄

Answer 1

@foreach($item->orderedProducts as $op)
<tr>
    <td>
    @if ('Extras' == $op->extra_type)
         <span>{{ $op->extra_name }}</span><br>
    @endif
    </td>
</tr>
@endforeach

Answer 2

我认为这会锻炼

@foreach($item->orderedProducts as $op)
<?php $array = stripslashes(json_encode($op->extras)) ?>
    <tr>
         <td>
             <span>
             @foreach($array as $value)
                 {{ $value['extra_name'] }}
             @endforeach
             </span><br>
         </td>
    </tr>
 @endforeach

Answer 3

您可以在laravel中使用->来访问对象值，请尝试

@foreach($item->orderedProducts as $op)
<tr>
 <td>
     <span>{{ $op->extra_name }}</span><br>
 </td>
</tr>
@endforeach

Answer 4

我解决了。我需要的是在遍历json对象数组时使用json_decode()。接下来，我提取了所需的属性。

@foreach($item->orderedProducts as $op)
<tr>
    <td>
        @foreach(json_decode($op->extras, true) as $extra)
             {{ $extra['extra_name'] }}<br>
        @endforeach
    </td>
</tr>
@endforeach
