Laravel 5 date_format驗證不驗證

Question

這是輸入值： FIRST_TIME_ARRIVAL_DATE_AT_DAW : 2016-21-5 17:21:35這是驗證規則：

public static $createRules = [
      'FIRST_TIME_ARRIVAL_DATE_AT_DAW' => 'date_format:"Y-m-d H:i:s"',
];

它不驗證，它返回：

{"CELLS_EXPIRY_DATE":["The FIRST TIME ARRIVAL DATE AT DAW does not match the format Y-m-d H:i:s."]

編輯：這是我的控制器的外觀：

$validator = Validator::make($request->all(),BatteryAssets::$createRules);
        if ($validator->fails()) {
            return ['success' => 0, 'data' => 'Input error','errors' => $validator->messages()->toJson()];
        }

因此$validator->messages()->toJson()返回驗證錯誤

Answer 1

format Y-m-d H:i:s need be 2016-21-05 17:21:35

Answer 2

將'date_format:"Ymd H:i:s"'更改為'date_format:Ymd H:i:s'
