【问题描述】：

我正在使用 CodeIgniter 4 的验证表单，我已经检查了帖子是否来了，但我每次都收到 FALSE，看看我的代码。

function login()   
    
    helper(['form', 'url']);
    
    $validation =  \Config\Services::validation();

    $validation->setRules([
        'email' => ['label' => 'E-mail', 'rules' => 'required'],
        'password' => ['label' => 'Senha', 'rules' => 'required|min_length[6]']
    ]);

    var_dump($this->validate($validation) ? true : false);exit;

我也试过了，

$rules = [
        'email' => ['label' => 'E-mail', 'rules' => 'required'],
        'password' => ['label' => 'Senha', 'rules' => 'required|min_length[6]']
    ];

var_dump($this->validate($rules) ? true : false);exit;

【问题讨论】：

你有没有尝试过一次在codeigniter.com/user_guide/libraries/… 上学习教程？

我做到了，兄弟...

【参考方案1】：

看看我的代码
