Question

我在CI应用程序中使用form_validation并在callback function中使用set_rules()时出错：

无法访问与您的字段名称对应的错误消息电子邮件（validate_credentials）

我的控制器代码是：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Auth extends MX_Controller 
{
    // public function __construct()
    // {
    //  parent::__construct();
    // }

    // public function index()
    // {
    //  $this->load->view('auth/login_v');
    // }

    public function login()
    {
        $this->load->view('auth/login_v');
    }

    public function login_validation()
    {
        //$this->load->library('form_validation');

        $this->form_validation->set_rules('email', 'Email', 'required|trim|callback_validate_credentials');
        $this->form_validation->set_rules('password', 'Password', 'required|md5|trim');

        if($this->form_validation->run())
        {
            redirect('dashboard');
        } else {
            $this->load->view('auth/login_v');
        }

        //echo $this->input->post('email');
    }

    public function validate_credentials()
    {
        $this->load->model('Auth_model');

        if($this->Auth_model->can_log_in())
        {
            return true;
        } else {
            $this->form_validation->set_message('validate_credentials', 'Incorrect Email/Password');

            return false;
        }
    }
}

我不知道我在哪里误会。我已将参数传递给tha回调函数：

$this->form_validation->set_rules('email', 'Email', 'required|trim|callback_validate_credentials[email]');

和

public function validate_credentials($email)
    {
        $this->load->model('Auth_model');

但我得到同样的错误。

我推荐了以下网站：

In Codeigniter, how to pass a third parameter to a callback (form validation)?

我正在为我的应用程序使用codeigniter 3.1.6和HMVC。

任何形式的帮助都会受到欢迎。感谢
