如何在$validator->fails()

内的控制器内获取所有请求名称

$validator = Validator::make($request->all(), [
    'patient_uname' => 'required|max:255|Alpha',
    'patient_pass' => 'required|max:255|Alpha'
]);

if ($validator->fails()) {

}

例如，如果patient_uname失败，则应显示patient_name

Answer 1

检查

public function postReset(Request $request)
    {
            $message = [
                'patient_uname.required' => 'Patient name is required',
                'patient_pass.required' => 'Patient pass is required'
            ];
            $this->validate(
                $request,
                [
                 'patient_uname' => 'required|max:255|Alpha',
                 'patient_pass' => 'required|max:255|Alpha'
                ],
                $message
            );

验证者需要三个参数

$validator = Validator::make($input, $rules, $messages);

$messages  = ['patient_uname.required' => 'patient name is required'];
$rules     = ['patient_uname' => 'required|max:255|Alpha'];

在您的问题中，只需传递一个消息数组

$validator = Validator::make($request->all(), [
    'patient_uname' => 'required|max:255|Alpha',
    'patient_pass' => 'required|max:255|Alpha'
], $messages);

Answer 2

您可以获取所有失败字段的键，如下所示：

if ($validator->fails()) {
    dd($validator->errors()->keys());
}

返回：

array:2 [
   0 => "patient_uname"
   1 => "patient_pass"
]

您可以收到像这样的所有错误消息

if ($validator->fails()) {
    dd($validator->errors()->all());
}

返回：

array:2 [
   0 => "The patient uname field is required."
   1 => "The patient pass field is required."
]

您可以获得一个这样的特定字段：

if ($validator->fails()) {
    dd($validator->errors()->get('patient_uname'));
}

返回：

array:1 [
    0 => "The patient uname field is required."
]
