我正在运行codeigniter 4.1.5和php 8.1.0，当我尝试输入数据时，这是我得到的错误

</div>
</body>这是我作为控制器的auth.php
<?php
namespace App\Controllers;
class Auth extends BaseController
{
public function __construct()
{
helper(['url', 'form']);
}
public function index()
{
return view('auth/login');
}
public function register()
{
return view('auth/register');
}
public function save()
{
$validation = $this->validate([
'name' => [
'rules' => 'required',
'errors' => [
'required' => 'Your name is required'
]
],
'email' => [
'rules' => 'required|valid_emails|is_unique[users.email]',
'errors' => [
'required' => 'Email is required',
'valid_email' => 'You must enter a valid email',
'is_unique' => 'Email already taken'
]
],
'password' => [
'rules' => 'required|min_length[5]|max_length[12]',
'errors' => [
'required' => 'Password is required',
'min_lenght' => 'Password must have atleast 5 character',
'max_lenght' => 'Password must not exceed 12 character'
]
],
'cpassword' => [
'rules' => 'required|min_length[5]|max_length[12]|matches[password]',
'errors' => [
'required' => 'Password is required',
'min_lenght' => 'Password must have atleast 5 character',
'max_lenght' => 'Password must not exceed 12 character',
'matches' => 'Confirms password not matches to password'
]
]
]);
if (!$validation) {
return view('auth/register', ['validation' => $this->validator]);
} else {
$name = $this->request->getPost('name');
$email = $this->request->getPost('email');
$password = $this->request->getPost('password');
$values = [
'name' => $name,
'email' => $email,
'password' => $password,
];
$userModels = new \App\Models\UsersModel();
$query = $userModels->insert($values);
if (!$query) {
return redirect()->back()->with('fail', 'something went wrong');
} else {
return redirect()->to('register')->with('success', 'You are now registered');
}
}
}
}这是我在form_helper.php中放入的内容
<?php
function display_error($validation, $field)
{
if ($validation->hasError($field)) {
return $validation->getError($field);
} else {
return false;
}
}我做错了什么？

CodeIgniter 4.1.5还不支持PHP 8.1。请使用8.0
或使用CI4的

您可以将空合并运算符添加到以下代码行：
$方法= strtolower（$方法）;将其改为：
$方法=低层（$方法？？"“）;
此更改应在库/RestController文件第835行中进行
