Php 验证工作不正常-即使向字段中插入值，该字段似乎也是必需的

当用户单击“转到步骤3”时，它会显示“

console.log（errorsHtml）；

“这：

换成这个试试

public function storePaymentMethods(Request $request, $id, $slug = null){

    $validatedData = $request->validate([
        'payment_method' => 'required',
    ]);
    return response()->json([
       'success' => true,
       'message' => 'success'
      ], 200);

    }

如何在ajax请求中显示这一点？这样就不会显示“公共函数storePaymentMethods（Request$Request，$id，$slug=null，Validator$Validator）{dd（$Request）…”。使用chrome控制台网络模式，您可以检查在网络预览中传递或不传递的PaymentMethod变量是否只是显示前一步（步骤1）字段引入的值。付款方法不显示，只显示上一步的字段。您使用的是哪一版本的laravel？laravel 5.5。谢谢，但仍然显示“{消息：“给定的数据无效。”，…}错误：{付款方法：[“付款方法字段是必需的。”]}消息：“给定的数据无效。”您是否检查了PaymentController和payment.blade.php中的PaymentMethods拼写是否相同？是否检查了PaymentController和payment.blade.php中的PaymentMethods拼写是否相同。如果没有出现任何验证错误，则在网络选项卡中选择storePaymentMethods时会显示“加载响应数据失败”。您能否通过更新问题中的错误图像
