始终验证 return 消息 'required is not a valid rule' |代码点火器 4

Question

我在配置/validation.php 中参考官方文档https://codeigniter4.github.io/userguide/libraries/validation.html 进行了验证，如下所示：

class Validation
{
   ....

   public $user = [
    'name' => [
        'rules' => 'required'
    ],
    'email' => [
        'rules' => 'valid_email|required',
        'errors' => [
            'valid_email' => 'E-mail is not valid',
            'required' => 'E-mail is required'
        ]
    ]
  ];
}

然后我在我的控制器上这样调用它：

....

class User extends ResourceController
{
   public function create()
   {

     $name = $this->request->getPost('name');
     $email = $this->request->getPost('email');
     $country = $this->request->getPost('country');
     $province = $this->request->getPost('province');
     $city = $this->request->getPost('city');
     $day_of_birth = $this->request->getPost('day_of_birth');
     $password = $this->request->getPost('password');
     $phone_number = $this->request->getPost('phone_number');
     $photo = $this->request->getPost('photo'); 

     $data = [
        'name' => $name,
        'email' => $email,
        'country' => $country,
        'province' => $province,
        'city' => $city,
        'day_of_birth' => $day_of_birth,
        'password' => $password,
        'phone_number' => $phone_number,
        'photo' => $photo
     ];

     $validate = $this->validation->run($data,'user');
     $errors = $this->validation->getErrors(); 

     if($errors){
        return $this->fail($errors);
     }
    
     return $this->respond($data);
   }
 }

当我使用邮递员对其进行测试时，我得到了这样的 return：

如果我在控制器中执行验证，验证工作正常，但我想在 validation.php 中声明验证，有人请帮助我，无论我在 validation.php 中写什么然后我调用使用 $this->validation->run($data,'name') 总是 return 相同

您没有在需要验证的名称中添加错误消息，所以可能是问题所在，因此您必须在名称中添加错误消息。

因为消息中的验证很重要。没有任何错误信息，用户怎么知道表单出了什么问题。

这里是自定义的函数或验证示例。改变你的功能就像。

class Validation
{
    public $user = [
        'name' => [
            'rules'  => 'required',
            'errors' => [
                'required' => 'Name is required.'
            ]
        ],
        'email'    => [
            'rules'  => 'required|valid_email',
            'errors' => [
                'valid_email' => 'E-mail is not valid',
                'required' => 'E-mail is required'
            ]
        ],
    ];
}
