Codeigniter Call Controller From Controller

Question

After the last two comments, I\'ll dump out my real code and maybe it will help out:

Here is the landing Controller:

Answer 1

So after lots of searching, I think I have a workaround. The issue what what I thought with the instance. After diving into the framework I realized that it is storing the instance into as static var, private static $instance. I modified the constructor to not overwrite if that var has been populated. On top of that, since there were some oddities still with the loading, for some reason objects would be marked as loaded but in reality were not, I had to add a new var to the controller, protected $ci_instance. In the end, I modified the CI_Controller to look like the following:

ci_instance =& get_instance(); // line added

        // Assign all the class objects that were instantiated by the
        // bootstrap file (CodeIgniter.php) to local class variables
        // so that CI can run as one big super object.
        foreach (is_loaded() as $var => $class)
        {
            $this->$var =& load_class($class);
        }

        $this->load =& load_class('Loader', 'core');

        $this->load->_base_classes =& is_loaded();

        $this->load->_ci_autoloader();

        log_message('debug', "Controller Class Initialized");
    }

    public static function &get_instance()
    {
        return self::$instance;
    }
}
// END Controller class

/* End of file Controller.php */
/* Location: ./system/core/Controller.php */

The only issue so far is that I cannot do $this->load->model("some_model");. Instead I have to use $this->ci_instance->load->model("some_model"); and everything will stem from there. I don't really care about the extra var, but what I don't like is modifying out of box solutions because it increases the complexity to do an upgrade.

for now I've marked this as an answer because it is what "I" have chosen to use as my solution, but I am still opened to a better solution than the one I am using. An exact description of what needs to be solved is as follows:

Copy all loaded properties from one instance to another. Basically do a merger of two instances if possible.

If someone can answer that with a better solution than mine, preferably without modifying the codeigniter core, I'd gladly change my answer because I am not happy with my solution because I don't know what effects I might encounter later on during development.
