CodeIgniter 3.0.3 ci_session未将会话数据保存到ci_sesstion表中 [英] CodeIgniter 3.0.3 ci_session not saving session data to ci_sesstion table
本文介绍了CodeIgniter 3.0.3 ci_session未将会话数据保存到ci_sesstion表中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是CodeIgniter的新手，并且登录\注销ci_session数据现在保存时遇到了一些问题。我已经使用CodeIgniter文档中的脚本设置了标准的ci_session表，并设置了配置文件以允许将会话存储在相关表中，但是没有任何内容。
I'm new to CodeIgniter and I'm having some issues with the login \ logout ci_session data now saving at all. I have setup the standard ci_session table using the script in the CodeIgniter docs and have setup the config file to allow session to be stored in the relevant table, but nothing is.
会话的config.php settinh：
config.php settinh for sessions:
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_encrypt_cookie'] = TRUE;
$config['sess_use_database'] = TRUE;
$config['sess_expire_on_close'] = TRUE;
$config['sess_table_name'] = 'ci_session';
$config['sess_expiration'] = 60 * 30;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_match_useragent'] = TRUE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = TRUE;
以下是MVC文件的登录表单：
Here are the login form MVC files:
模型登录
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class login_model extends CI_Model
{
function __construct()
{
// Call the Model constructor
parent::__construct();
}
//get the username & password from tbl_usrs
function get_user($username, $password)
{
$this->db->where('username', $username);
$this->db->where('password', sha1($password));
$query = $this->db->get('tbl_users');
return $query->num_rows();
}
}
查看登录
<?php defined('BASEPATH') OR exit('No direct script access allowed'); ?>

控制器登录
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class login extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('account/login_model');
}
public function index()
{
$data['Title'] = "";
$data['Description'] = "";
$data['Keywords'] = "";
$data['Type'] = "";
$data['Url'] = "";
$this->load->view('includes/header', $data);
//get the posted values
$username = $this->input->post("txt_username");
$password = $this->input->post("txt_password");
//set validations
$this->form_validation->set_rules("txt_username", "Username", "trim|required|min_length[8]|max_length[30]|xss_clean");
$this->form_validation->set_rules("txt_password", "Password", "trim|required|min_length[8]|max_length[32]|xss_clean");
if ($this->form_validation->run() == FALSE)
{
//validation fails
$this->load->view('account/login');
}
else
{
//validation succeeds
if ($this->input->post('btn_login') == "Login")
{
//check if username and password is correct
$usr_result = $this->login_model->get_user($username, $password);
if ($usr_result > 0) //active user record is present
{
//set the session variables
$sessiondata = array(
'username' => $username,
'loginuser' => TRUE
);
$this->session->set_userdata($sessiondata);
redirect("members/members_area");
}
else
{
$this->session->set_flashdata('msg', '<div class="alert alert-danger text-center">Invalid username or password! Please try again.</div>');
redirect('account/login');
}
}
else
{
redirect('account/login');
}
}
$this->load->view('includes/footer');
}
}
登录似乎有效并重定向到成员区域，但是当我检查ci_session表时，它为空。
The login seems to work and redirects to the members area however when I check the ci_session table it's empty.
在成员区域中，我想注销一次，这应该破坏当前会话，然后重定向到不起作用的index.php主页。
Once in the members area I want to logout which should destroy the current session and then redirect to the index.php home page which is doesn't do.
这里是成员V\C
控制器成员区域
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Members_Area extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->loginuser();
}
public function index()
{
$data['Title'] = "";
$data['Description'] = "";
$data['Keywords'] = "";
$data['Type'] = "";
$data['Url'] = "";
$this->load->view('includes/member_header' , $data);
$this->load->view('members/members-area');
$this->load->view('includes/footer');
}
function loginuser()
{
$loginuser = $this->session->userdata('loginuser');
if (!isset($loginuser) || $loginuser != true )
{
echo 'Sorry you dont have premission to access this area. Please signup and login to gain access to this area.';
die();
}
}
}
查看成员区域
VIEW MEMBER AREA
<div class="container">
<div class="well col-xs-12 col-sm-12 col-md-12 col-lg-12">
<h3>Members Area</h3><br />
</div>
</div>
这是注销V和C
控制器注销
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Logout extends CI_Controller {
public function index()
{
$data['Title'] = "";
$data['Description'] = "!";
$data['Keywords'] = "";
$data['Type'] = "";
$data['Url'] = "";
$this->load->view('includes/header' , $data);
// destroy session
$this->session->sess_destroy();
// redirect to other page
redirect('account/logout');
$this->load->view('includes/footer');
}
}
查看注销
<?php defined('BASEPATH') OR exit('No direct script access allowed'); ?>
<div class="container">
<div class="col-xs-12 col-sm-9 col-md-9 col-lg-9">
<h2>You have logged out.</h2>
</div>
</div>
<div class="col-xs-12 col-sm-3 col-md-3 col-lg-3">
<p>test</p>
</div>
</div>
大家的任何建议或指导都是巨大的帮助。
Any advice or direction from you folks would be a huge help.
谢谢！
推荐答案
在config.php文件中，您需要启用ci会话：
In your config.php file you need to enable ci session:
$config['sess_use_database'] = TRUE;
来自CI用户指南：
一旦启用，Session类将在数据库中存储会话数据。
Once enabled, the Session class will store session data in the DB.
确保已在配置文件中将表名指定为好：
Make sure you've specified the table name in your config file as well:
$config['sess_table_name'] = 'ci_sessions';
您可以根据表名更改此名称。
You can change this name as per your table name.
