我有以下代码:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Login extends MY_Controller
{
function __construct()
{
parent::__construct();
$this->load->model('users/user_model');
$this->load->library('form_validation');
}
function _load_login_page()
{
$this->load->model('sysconfig/sysconfig_model');
$a = $this->sysconfig_model->get_sysconfig();
$row = $a[0];
$this->lang->load('klas',$row->sysconfig_language);
$data['sys_name'] = $row->sysconfig_system_name;
$data['template_name'] = $row->systemplate_name;
$data['css_script'] = base_url().'assets/'.$row->systemplate_name;
if($row->sysconfig_maintenance === 'Y')
{
$this->load->view('sysconfig/maintenance',$data);
}
else {
$this->load->view('login',$data);
}
}
function index()
{
$this->form_validation->set_rules('username', 'Username', 'trim|required|max_length[12]|xss_clean|callback_check_auth');
$this->form_validation->set_rules('password','Password','trim|required');
if($this->form_validation->run($this) == FALSE)
{
$this->_load_login_page();
} else {
redirect('welcome','refresh');
}
}
function check_auth()
{
if($this->user_model->authentication())
{
return TRUE;
}
$this->form_validation->set_message('check_auth',$this->lang->line('invalid_username'));
return FALSE;
}
?>
用户模型.php
<?php
class User_Model extends CI_Model
{
function authentication()
{
$this->db->where('useracc_id', $this->input->post('username'));
$this->db->where('useracc_password', md5($this->input->post('password')));
$q = $this->db->get('base_useracc');
if($q->num_rows() == 1)
{
$session_data = array('isUserLogged'=>TRUE);
$this->session->set_userdata($session_data);
return TRUE;
}
}
?>
从这里我们可以看到如果用户没有填写用户名和密码字段,它将显示错误并且一切都按预期工作。问题是,如果用户提供了无效的用户名或密码,则不会显示错误消息。
对于信息,我已经放入$lang['invalid_username'] = 'Invalid username or password';
了语言文件。
我正在使用 HMVC 技术进行此操作。请帮我。
