There are three classes:

Standard controller class:

class LoaderContent extends CI_Controller {
        public function __construct(){
        $obj = new SearchNew();

abstract class Search
// Get here access to get_instance

class SearchNew extends Search
    public function __construct()


How to get access to a Codeigniter instance in an abstract class?

    In Codeigniter, get_instance() is a globally available function that returns the Controller super-object which contains all the currently loaded classes (it returns the Controller class instance). First, assign the CodeIgniter object to a variable:

    $CI =& get_instance();

    Once you've assigned the object to a variable, you'll use that variable instead of $this:

    $CI =& get_instance(); 


    Note: You'll notice that the above get_instance() function is being passed by reference:

    $CI =& get_instance();
