CodeIgniter - Check if Session variable exist

In CodeIgniter, checking if an input exists is easy.

Rather than using

$something = isset($_POST['something']) ? $_POST['something'] : NULL;

You can simply do:

$something = $this->input->post('something');

My question is, is it the same with session?

$something = isset($_SESSION['something']) ? $_SESSION['something'] : NULL;

the same with

$something = $this->session->something;

Yes, $this->session->something will work just fine.

Just remember to load the library. And read the manual if you like:

Check whether session variable is set or not using $this->session->has_userdata('variable'); so try like this..

$something = $this->session->has_userdata('something')? $this->session->userdata('something') : NULL;

if session variable is not set then $something has NULL value otherwise it has session value.
