Question

In Controller

Answer 1

I consider storing my session data in a controller. So this is how you should go about storing and retrieving session data

1.Use autoload in your config.php files. It saves you time and load time

autoload['libraries'] = ('session);

2.In your controller.php create an array to store your session data.

$new_data = array( 'username' => 'martin', 'email' => 'someone@martin.com', 'user_logged => TRUE );

$this->session->set_userdata($new_data);

3. Then this is how to call your session data(create a variable and assign it the value of one of the session data you need):

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