Codeigniter登录系统问题记录 [英] Codeigniter login system issue loging
问题描述
我有一个表"usuarios"，其中包含以下信息:
I got a table "usuarios" which contains the following information:
(ID，用户名，名称，姓氏，密码，类型，状态，日期)，对吗?
(id, username, name, lastname, password, type, status, date), right?
看看:
我的个人目标是建立一个登录系统，使我可以从那些只是简单用户的用户中区分那些谁是ADMIN ...我的意思是，如果表中的一行包含type = 0，则它是ADMIN，如果type = 1，这是一个简单的用户. 因此，在登录系统中，如果我编写例如ADMIN 1234，并且此数据对应于"users"表中的ADMIN用户；当我按下登录"按钮时，它必须仅为ADMIN打开一个独占页面..但对于简单"用户则相同.
My personal goal is to make a login system which allows me to clasify those WHO are ADMIN from those who are just simple users... I mean, if a row of the table contains type = 0 it is an ADMIN and if type = 1 it is a simple user. So,in the login system if i write for example ADMIN 1234 and this data corresponds to an ADMIN user from the table "users"; when i press "login" it must open an exclusive page only for ADMINs.. The same but for those who are "simple" users.
系统必须验证我是否输入了错误的用户名/密码，以及用户名是否对应于活动成员(状态= 1活动，状态= 0非活动).登录时没有空字段
The system must validate if i write wrongs usernames/passwords and if the username corresponds to an active member (status = 1 active, status = 0 not active). No empty fields while login
无论我在登录系统中的用户名"和密码"中写什么..当我单击登录"时，我总是收到此消息，但没有任何反应:
这些是在我的数据库中注册的用户:
And these are the users registered in my database:
这是我的代码: 控制器文件(2个文件:仪表板"和登录") 仪表板:
Here is my code: Controller files (2 files: "dashboard" and "login") Dashboard:
<?php
Class dashboard extends CI_Controller{
public function __construct(){
parent::__construct();
$this->load->model('m_login');
$this->auth->cek_auth();
}
public function index(){
$ambil_akun = $this->m_login->ambil_user($this->session->userdata('usuario'));
$data = array(
'user' =>$ambil_akun,
);
$stat = $this->session->userdata('lvl');
if($stat=='s_admin'){
$this->load->view('dashboard_admin', $data);
}else{
$this->load->view('dashboard_user', $data);
}
}
public function login(){
$session = $this->session->userdata('isLogin');
if($session == FALSE)
{
$this->load->view('login_form');
}else
{
redirect('dashboard');
}
}
public function logout(){
$this->session->sess_destroy();
redirect('login', 'refresh');
}
}
?>
登录:
<?php
Class Login extends CI_Controller{
public function __construct(){
parent::__construct();
$this->load->model("m_login");
}
public function index(){
$session = $this->session->userdata('isLogin');
if($session == FALSE)
{
$this->load->view('login_form');
}else
{
redirect('dashboard');
}
}
public function do_login()
{
$usuario=$this->input->post('uname');
$contrasena=$this->input->post('pass');
$cek=$this->m_login->cek_user($contrasena, md5($contrasena));
if(count($cek) == 1){
foreach ($cek as $cek) {
$tipo=$cek['tipo'];
$estado=$cek['estado'];
$nombre=$cek['nombre'];
}
if($estado =='0'){
$this->session->set_userdata(array(
'isLogin'=>TRUE,
'uname'=>$usuario,
'lvl'=>$tipo,
'estado'=>$estado
));
redirect('dashboard', 'refresh');
}
else{
echo "<script>alert('YOUR ACCOUNT IS NOT ACTIVE')</script>";
redirect('login','refresh');
}
}else{
echo "<script>alert('USERNAME OR PASSWORD INVALID!')</script>";
redirect('login','refresh');
}
}
}
?>
模型文件(m_login):
The model file (m_login):
<?php
class m_login extends CI_Model{
public function __construct(){
parent::__construct();
$this->tbl="usuarios";
}
public function cek_user($usuario="", $contrasena="")
{
$query=$this->db->get_where($this->tbl, array('usuario'=>$usuario, 'contrasena'=>$contrasena));
$query=$query->result_array();
return $query;
}
public function ambil_user($nombre)
{
$query=$this->db->get_where($this->tbl, array('nombre'=> $nombre));
$query=$query->result_array();
if(query){
return $query[0];
}
}
}
?>

dashboard_user:
dashboard_user:
Hi!<b><?php echo $user['nombre'];?></b>YOU ARE A SIMPLE USER! > [<a href= '<?php echo base_url('dashboard/logout');?>'>LOGOUT</a>]
不知道现在该怎么做:/
Dont know what to do now :/
推荐答案
在此代码中，您对密码进行了加密.但是在db上，它没有用md5加密吗? 也许不使用md5发送就可以解决您的问题.但我认为也可以使用md5的良好选择进行加密.
in this code, you encrypt password. But on db, its not encrypted with md5 ? Maybe sending without md5 will solve your problem for now. But i think also encrypt with md5 good selection.
$cek=$this->m_login->cek_user($contrasena, $contrasena); // change like this.
