如何访问json字符串中的数据[重复]

Question

因此，我通过 POST 请求从 Ionic 应用程序向 API 发送一组调味品，这些调味品在移动部分上表示为复选框。我想要获取已选中的复选框，以便我可以相应地创建表行。

路由触发时调用的方法有这部分：

$condiments = Input::only('condiments');

foreach ($condiments as $condiment) {
    if ($condiment['checked'] == 1) {
        OrderCondiment::create([
            'order_item_id' => $orderItem, 
            'condiment_id' => $condiment->id
        ]);
    }
}

但是我收到

Illegal string offset 'checked'

错误。我尝试使用

$condiment->checked

但后来我得到

Trying to get the property of non-object

错误...我还缺少什么...除了咖啡

编辑

dd($condiments)

array:1 [
  "condiments" => "[{"id":1,"name":"ut","price":3,"created_at":null,"updated_at":null,"checked":1},{"id":2,"name":"ipsam","price":5,"created_at":null,"updated_at":null,"checked":1},{"id":3,"name":"dolores","price":10,"created_at":null,"updated_at":null,"checked":1},{"id":4,"name":"esse","price":3,"created_at":null,"updated_at":null,"checked":0},{"id":5,"name":"aliquid","price":1,"created_at":null,"updated_at":null,"checked":0},{"id":6,"name":"sunt","price":3,"created_at":null,"updated_at":null,"checked":0},{"id":7,"name":"saepe","price":1,"created_at":null,"updated_at":null,"checked":0},{"id":8,"name":"impedit","price":10,"created_at":null,"updated_at":null,"checked":0},{"id":9,"name":"dolores","price":4,"created_at":null,"updated_at":null,"checked":0},{"id":10,"name":"veniam","price":2,"created_at":null,"updated_at":null,"checked":0}]"
]

将字符串转换为数组

$condiments = Input::only('condiments');
$condiments= json_decode( $condiments['condiments']) ;
foreach ($condiments as $condiment) {
    if ($condiment->checked == 1) {
        OrderCondiment::create(['order_item_id' => $orderItem, 
                                'condiment_id' => $condiment->id]);
    }
}
