如何将错误映射到字段？

Question

下面是我在 lumen 中的服务器端验证：

$rules = array(
            'prog_code' => 'required',
            'payer_id' => 'required',
        );
        $validator = \Validator::make($post, $rules);
        if (!$validator->fails()) {
            try {
                // Start Logic Here
            } catch (\Exception $e) {

            }
        } else {
            $errors = $validator->errors();
            return response()->json($errors->all());
        }

它返回如下错误：

[
    "The prog code field is required.",
    "The payer id field is required.",
]

但问题是我如何映射哪个字段的错误，因为我想在特定文本字段下方显示错误。

我们可以自定义如下错误吗：

[
        [prog_code] => "The prog code field is required.",
        [payer_id] => "The payer id field is required.",
]

Answer 1

我实现相同响应的方法是：

if ( $validator->fails() ) {
  $errors = [];

  foreach ( $validator->errors()->toArray() as $field => $message ) {
    $errors[$field] = $message[0];
  }

  return response()->json($errors);
}

如果您转储 $errors 变量，您会遇到一系列错误，例如您的目标：

ViewErrorBag {#406
  #bags: array:1 [
    "default" => MessageBag {#407
      #messages: array:1 [
        "pin" => array:1 [
          0 => "The Programming Code is required Sir!"
        ]
      ]
      #format: ":message"
    }
  ]
}

$errors变量在出现错误时被验证器注入
