To get the username with sessions in CodeIgniter, you can follow these steps:

1. Load the session library: In your CodeIgniter controller, load the session library by adding the following code in the constructor or in a method where you need to access the session data:

1

$this->load->library('session');

1. Set the session data: When a user logs in or authenticates, set the username in the session data using the set_userdata() method. For example:

1
2

$username = 'john.doe'; // Assuming the username is stored in a variable
$this->session->set_userdata('username', $username);

1. Retrieve the session data: To retrieve the username from the session, you can use the userdata() method. For example, to get the username in a different controller or view:

1

$username = $this->session->userdata('username');

Make sure to load the session library in any controller or view where you want to access the session data.

Note: Please ensure that your application's session configuration is properly set and sessions are initialized before using them.
