我有一个非常奇怪的错误，1个输入字段总是返回一个空值，即使它填充了一个值。
我的表格：

当我点击提交并添加（）时，我得到的值是：
#attributes: array:7 [▼
"email" => "testing@test.com"
"name" => "Christina testname"
"password" => "$2y$10$njMYm6uJMxoI4e9n/157vOLPLBBkViUE6uI3I3K8apdkhLnExQs7."
"first_name" => ""
"surname" => "Furler"
"date_of_birth" => "2009-01-14"
"phone" => "123456798"
]
问题只有字段first_name总是返回一个空字符串。所有其他输入字段都可以正常工作。空值存储在数据库中，因此控制器部分按预期工作。
额外代码（我处理请求的UserController）
public function store(CreateUserRequest $userRequest, CreateAddressRequest $addressRequest)
{
$user = new User([
'email' => $userRequest->email,
'name' => $userRequest->name,
'password' => bcrypt($userRequest->password),
'first_name' => $userRequest->first_name,
'surname' => $userRequest->surname,
'date_of_birth' => $userRequest->date_of_birth,
'phone' => $userRequest->phone
]);
$user->save();
您有两个名称相同的文本输入字段。可能是的原因
<div class="col-sm-10"><input type="text" value="{{old('first_name')}}" name="first_name" class="form-control"></div>
<div class="col-sm-10"><input type="text" value="{{old('btw_number')}}" name="first_name" class="form-control"></div>
