writing a library that uses other libraries

[eluser]dadamssg[/eluser]
fixed it. I wasn't using $CI when i was referencing my session variables

*fixed*

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Loginclass {

    public function logged_in()
    {
        //load codeigniter object
        $CI =& get_instance();
        
        //load session library to use
        $CI->load->library('session');    
        
        //set values to check
        $username = $CI->session->userdata('username');
        $logged_in = $CI->session->userdata('logged_in');    
        
        //check values
        if(empty($username)){$value = FALSE;}
        elseif(!is_numeric($username)){$value = FALSE;}
        elseif($logged_in !== TRUE){$value = FALSE;}
        else{$value = TRUE;}
        
        
        return $value;
    }
}

?>
