Question

我从Laravel客户端上的RESTfull API获取此错误消息包，我想向用户显示错误，但我很难在包中显示错误一个数组。

nginx root /home/deploy/app_name/public; to /home/deploy/app_name/current/public;

我知道显示错误的常规方法，例如打印性别错误，我可以这样做：

MessageBag {#251 ▼
  #messages: array:6 [▼
    "gender" => array:1 [▶]
    "first_name" => array:1 [▼
      0 => "The first name must be at least 2 characters."
    ]
    "last_name" => array:1 [▶]
    "user_id" => array:1 [▶]
    0 => array:4 [▼
      "user_id" => array:1 [▶]
      "address2" => array:1 [▼
        0 => "The address2 must be at least 3 characters."
      ]
      "zip" => array:1 [▶]
      "phone" => array:1 [▶]
    ]
    1 => array:4 [▼
      "user_id" => array:1 [▶]
      "address2" => array:1 [▼
        0 => "The address2 must be at least 3 characters."
      ]
      "zip" => array:1 [▶]
      "phone" => array:1 [▶]
    ]
  ]
  #format: ":message"
}

或检查是否有性别＆＃39;错误存在：

{!! $errors->first('gender', '<label class="control-label"><i class="glyphicon glyphicon-menu"></i> :message</label>') !!}

但是如何检查数组0是否存在并显示错误？

谢谢：）

目前在Laravel 5.1打印带有数组的MessageBags是不可行的，我的解决方案是为次要错误实例化不同的MessageBag，而不是将其嵌套在主MessageBag上。

另一个可行的解决方案是将其嵌套：

MessageBag {#251 ▼
  #messages: array:6 [▼
    "gender" => array:1 [▶]
    "first_name" => array:1 [▼
      0 => "The first name must be at least 2 characters."
    ]
    "last_name" => array:1 [▶]
    "user_id.0.errors" => array:1[▼
      0 => "True"
    ] 
    "user_id.0.error_name" => array:1[▼
      0 => "The first name must be at least 2 characters"
    ] 
    "user_id.1.errors" => array:1[▼
      0 => "True"
    ] 
    "user_id.1.error_name" => array:1[▼
      0 => "The first name must be at least 2 characters"
    ] 
  ]
  #format: ":message"
}

但这不是一个干净的方式，正如我所说，创建一个辅助MessageBag更干净，更容易：）

messageBag与数组L5.1
