Place Teknicode_signin.php into you application/libraries directory.
Setup a users mysql database table with the following structure
CREATE TABLE `users` (
`id` int(11) NOT NULL,
`username` varchar(255) COLLATE utf8_bin DEFAULT NULL,
`password` varchar(255) COLLATE utf8_bin DEFAULT NULL,
`last_login` datetime DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
ALTER TABLE `users`
ADD PRIMARY KEY (`id`);
ALTER TABLE `users`
MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;
COMMIT;
Add teknicode_signin to the $autoload['libraries'] array in application/config/autoload.php
Alternatively you can load in the controller using
$this->load->library("teknicode_signin");class Login extends CI_Controller {
public function __construct(){
parent::__construct();
/*
* if $_POST['username'] && $_POST['password'] exist,
* this class method will attempt to login
*/
$this->teknicode_signin->login();
}
public function index(){
/*
* A visit to base_url("login") will land here, destroy the user session
* and show your login template
*/
$this->teknicode_signin->logout();
$this->load->view('login');
}
}To force a user login, add this to the __construct method of the controller in question.
All routes through the controller will require login before access is granted.
$this->teknicode_signin->secure();If your controller doesn't have a __construct method use you'll need to create one.
public function __construct(){
parent::__construct();
$this->teknicode_signin->secure();
}If a user session isn't present a redirection will occur to
base_url("login");
Your login page should post "username" and "password" to base_url("login");. Here is a basic login page using Bootstrap 4.
