Messing with OOP in Codeigniter

First, since you want to use CI resources in your library, you have to grab a reference to CI. For example, here's what I would do:

Code:

class FQGallery{
    private $CI;
    //Other member variables
    ...

    public function __construct($options){
        $this->CI =& get_instance();

        //Set member variables using $options array
        ...

        $this->CI->load->database();
        $this->CI->load->model('m_fqgallery');
        $this->CI->load->library(array('form_validation', 'session'));
    }

    ...
}

I would also return 'this' in my methods in case I wanted methods to be chainable.

Next, in the controller:

Code:

class Gallery extends CI_Controller{
    public function __construct(){
        parent::__construct();
        
        $options = array(
            'setting1' => 'value1',
            'setting2' => 'value2'
            ...
        );
        $this->load->library('fqgallery', $options, 'gallery'); //$this->gallery now refers to fqgallery
    }
}
