A summing that you have an Auth Library just add this to use database sessions.

Code:

// -----------------------------------------------------------------------

/**
  * logged_in()
  *
  * Check to see if a user is logged in.
  *
  * Look in the session and return the 'logged_in' field.
  *
  * @access public
  * @return bool
  */
public function logged_in()
{
  return ($this->_ci->session->userdata('logged_in') == TRUE) ? TRUE : FALSE;
}

Create an auth_helper in ./application/helpers and autoload it.

Code:

// ------------------------------------------------------------------------

/**
* logged_in()
*
* @access public
* @return bool
*/
if ( ! function_exists('logged_in'))
{
function logged_in()
{
  $_ci = get_instance();
  return ($_ci->auth->logged_in() == TRUE) ? TRUE : FALSE;
}
}

Then you can check if the user is logged like this.

Code:

if (logged_in())
{
    // code for user is logged in.
}
else
{
    // code for user is not logged in.
}

You will need to set the logged_in field in the session user_data when they log in.
