Best practises in checking codeigniter sessions
There are many practices in checking the session conditions for whether the user is logged in or not
Usually we check in the codeigniter controllers
function my_function() {$user = $this->session->userdata(‘user_id’);
if (!isset($user)) {
$logged_in = false;
}
else {
$logged_in = true;
}
}
This 4-8 lines of code you need to check in every controller , So you can create a codeigniter library and call the library function in every controller , It is easy to code and also in modifying the code
Create a my_library.php file in application/libraries
Copy the following code to my_library.php
class My_library extends Controller//CI_Controller {public function __construct()
{
parent::__construct();
} public function is_logged_in()
{
$user = $this->session->userdata(‘user_id’);
return isset($user);
}
}
Create a controller x.php
Call the is_logged_in function using $this->is_logged_in();
class X extends My_library{
public function __construct()
{
parent::__construct();
} public function do_something()
{
if ($this->is_logged_in())
{
// The user is logged in
} else{ //redirect to login page }
}
}
