[英]Cookie not working with Login System CodeIgniter
I have implemented a basic login system using CodeIgniter. 我已经使用CodeIgniter实现了基本的登录系统。 I am using the sessions
library to control access to a members only section. 我正在使用sessions
库来控制对“仅限会员”部分的访问。 I can log in and view this area no problem. 我可以登录并查看该区域没有问题。 However when I delete my cookies and refresh the members only section page I can still see the content. 但是,当我删除Cookie并刷新“仅限会员”部分页面时,仍然可以看到内容。 I am not displaying a login message to the user. 我没有向用户显示登录消息。
I don't know why this is happening. 我不知道为什么会这样。 Any ideas? 有任何想法吗?
This is my Site.php controller 这是我的Site.php控制器
class Site extends CI_Controller{
function _construct(){
parent::_construct();
$this->is_logged_in();
}
function members_area(){
$this->load->view('members_area');
}
function is_logged_in(){
$is_logged_in = $this->session->userdata('is_logged_in');
if(!isset($is_logged_in) || $is_logged_in != true){
echo 'You need to login to access this page. <a href="../login">Login</a>';
die();
}
} } }}
This is my login.php Controller 这是我的login.php控制器
class Login extends CI_Controller{
function index(){
$data['main_content'] = 'login_form';
$this->load->view('includes/template', $data);
}
function validate_credentials(){
$this->load->model('membership_model');
$query = $this->membership_model->validate();
if($query){//if credentials validated
$data = array(
'username' => $this->input->post('username'),
'is_logged_in' => true
);
$this->session->set_userdata($data);
redirect('site/members_area');
}
else{//If not validated re load login form
$this->index();
}
}
function signup(){
$data['main_content'] = 'signup_form';
$this->load->view('includes/template', $data);
}
function create_member(){
$this->load->library('form_validation');
//field name, error message, validation rules
$this->form_validation->set_rules('first_name', 'Name', 'trim|required');
$this->form_validation->set_rules('last_name', 'Last Name', 'trim|required');
$this->form_validation->set_rules('email_address', 'Email Address', 'trim|required|valid_email');
$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[4]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');
$this->form_validation->set_rules('password2', 'Password Confirmation', 'trim|required|matches[password]');
if($this->form_validation->run() == FALSE){
$this->signup();
}
else{
//create a new row in db
$this->load->model('membership_model');
if($query = $this->membership_model->create_member()){
//Info entered
$data['main_content'] = 'signup_successful';
$this->load->view('includes/template', $data);
}
else{
$this->load->view('signup_form');
}
}
}
} }
This is the code that should be executed if a session does not exist. 如果会话不存在,这是应该执行的代码。 It is found in the site.php
file. 在site.php
文件中找到它。
if(!isset($is_logged_in) || $is_logged_in != true){
echo 'You need to login to access this page. <a href="../login">Login</a>';
die();
Any help is much appreciated! 任何帮助深表感谢!
Looks like your constructor isn't being called. 看起来您的构造函数没有被调用。
Perhaps it is because it needs two underscores, not 1 :) 也许是因为它需要两个下划线,而不是1 :)
function __construct(){
parent::__construct();
$this->is_logged_in();
}
