英文:
Error validation does not appear CodeIgniter 4
问题
我在CodeIgniter 4的验证错误方面遇到了问题，当我点击按钮时，错误消息根本不会出现，有什么问题吗？请帮忙，我非常感激。
以下是代码：
控制器
public function Daftar()
{
// 如果验证通过
if ($this->validate([
'nim' => [
'label' => 'NIM',
'rules' => 'required|is_unique[tbl_anggota.nim]',
'errors' => [
'required' => '{field} Masih Kosong!',
'is_unique' => '{field} NIM Sudah Terdaftar!',
]
],
'nama' => [
'label' => 'Nama',
'rules' => 'required',
'errors' => [
'required' => '{field} Masih Kosong!',
]
],
'password' => [
'label' => 'Password',
'rules' => 'required',
'errors' => [
'required' => '{field} Masih Kosong!',
]
],
'ulangi_password' => [
'label' => 'Ulangi Password',
'rules' => 'required|matches
',
'errors' => [
'required' => '{field} Masih Kosong!',
'matches' => '{field} Password Tidak Sama!',
]
],
])) {
} else {
// 如果验证未通过
session()->getFlashdata('errors', \Config\Services::validation()->getErrors());
return redirect()->to(base_url('Auth/Login'))->withInput('validation', \Config\Services::validation());
}
}
视图
<?php
// 错误通知
$errors = session()->getFlashdata('errors');
if (!empty($errors)) { ?>
<div class="alert alert-danger" role="alert">
<h4>Periksa Entry Form</h4>
<ul>
<?php foreach ($errors as $key => $error) { ?>
<li><?= esc($error) ?></li>
<?php } ?>
</ul>
</div>
<?php } ?>
非常感谢！！
我尝试查找解决方法，但仍然不起作用。

你需要在控制器中设置错误时使用[setFlashData()][1]而不是getFlashData()，所以请将以下代码更改为：
..
session()->setFlashdata('errors', \Config\Services::validation()->getErrors());
..
英文:
you need to use setFlashData() instead of getFlashData() while setting error in your controller, so change:
..
session()->getFlashdata('errors', \Config\Services::validation()->getErrors());
..
to
..
session()->setFlashdata('errors', \Config\Services::validation()->getErrors());
..
