Question

Kohana

There is a Common controller

abstract class Controller_Common extends Controller_Template {

and Controller Products

class Controller_Products extends Controller_Common {

How do I declare a $xxx variable in Common and output it to Products?

Answer 1

And what are the difficulties?

abstract class Controller_Common extends Controller_Template {
    protected $_xxx = 'ololo';
}

class Controller_Products extends Controller_Common {
    public function __construct() {
        die('унаследованная переменная: ' . $this->_xxx);
    }
}
