Where to put standard functions that reference lib/mod methods

You can make your own MY_Controller and MY_Model.

PHP Code:

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

class MY_Controller extends CI_Controller {

function __construct()
{
  parent::__construct();
}

//your basic functions here

} 


PHP Code:

class MY_Model extends CI_Model {

function __construct()
{
  parent::__construct();
}

//your basic functions here

} 


Save both files in the application/core folder.

Now, when you create a controller that needs the basic functions in your MY_Controller, you start it like in the example below:

PHP Code:

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

class Home extends MY_Controller {


} 


And the same goes for models that are based upon your own MY_Model.
