How Can I Access One CodeIgniter Controller from Another?

Accessing Controllers from Other Controllers in CodeIgniter

In CodeIgniter, it is often desirable to load a controller from another controller without explicitly specifying the controller in the URL. This can help maintain code cleanliness and organization, particularly when you have a library that you want to integrate without cluttering up your main controller.

To achieve this, you can use the following steps:

1. Load the Controller Library:

   • In the controller from which you want to load another controller, use the following line of code:

     $this->load->library('../controllers/desired_controller');

   • Note that the path to the other controller should be relative to your current controller's file.

2. Access the Controller Function:

   • After loading the controller library, you can access its functions by calling them as methods of the loaded library object. For example:

     $this->desired_controller->function_name();

This approach allows you to keep your controllers clean and separated while still allowing you to access other controller functions when necessary.
