how to get an error key in laravel error message array
提问by Mohamed Athif
I am trying to retrieve a key from an array using Laravel error dump ($errors).
我正在尝试使用 Laravel 错误转储 ( $errors)从数组中检索密钥。
The array looks like this
数组看起来像这样
ViewErrorBag {#169 ▼
#bags: array:1 [▼
"default" => MessageBag {#170 ▼
#messages: array:2 [▼
"name" => array:1 [▼
0 => "The name field is required."
]
"role_id" => array:1 [▼
0 => "The role id field is required."
]
]
#format: ":message"
}
]
}
Using @foreachloop to get the error message works fine.
使用@foreach循环获取错误消息工作正常。
@foreach($errors->all() as $error)
<li>{{$error}}</li>
@endforeach
But I want to get that nameand role_id. Is there anyway to achieve that? Thus far i have tried the below and some other methods with no luck.
但我想得到那个name和role_id。有没有办法做到这一点？到目前为止，我已经尝试了以下方法和其他一些方法，但都没有运气。
@foreach ($errors->all() as $key => $value)
Key: {{ $key }}
Value: {{ $value }}
@endforeach

It's because, the $errors->all()returns an array of all the errors for all fields in a single array (numerically indexed).
这是因为，$errors->all()返回一个数组，其中包含单个数组中所有字段的所有错误（数字索引）。
If you want to loop and want to get each key => valuepairs then you may try something like this:
如果你想循环并想得到每一key => value对，那么你可以尝试这样的事情：
@foreach($errors->getMessages() as $key => $message)
{{$key}} = {{$message}}
@endforeach
But , you may explicitly get an item from the errors, for example:
但是，您可以明确地从错误中获取一个项目，例如：
{{ $errors->first('name') }} // The name field is required.
Maybe it's wise to check before you ask for any error for a field using something like this:
也许明智的做法是在使用以下内容询问字段的任何错误之前进行检查：
@if($errors->has('name'))
{{ $errors->first('name') }}
@endif
This'll help you to show each error at the top/bottom of the field that the error belongs to.
这将帮助您在错误所属字段的顶部/底部显示每个错误。

Use
用
@foreach($errors->getMessages() as $key => $error )
Key: {{ $key }}
Value: {{ $error[0] }}
@endforeach
if you var_dump the value of $error, you get an array:
如果你 var_dump $error 的值，你会得到一个数组：
array(1) { [0]=> string(13) "Successfully!" }
array(1) { [0]=> string(13) "Successfully!" }
thus you need the key (0 in our case) of that array to access the message
因此您需要该数组的键（在我们的例子中为 0）来访问消息

to loop through errors
遍历错误
@foreach($errors->getMessages() as $key => $message)
{{$key}} = {{$message[0]}}
@endforeach
