Answer 1

Add this to your plugin or themes' functions.php template:

function register_session(){
if( !session_id() ) //checking if session already exists
    session_start();
}
add_action('init','register_session');

Then to set the session data use something like this:

$_SESSION['username'] = 'some data';
