Controllers are used to handle HTTP requests.

Custom controllers must created in \brixy\App\Controllers\custom folder.

Full documentation about Controllers in Codeigniter.

namespace brixy\App\Controllers\custom;
use brixy\Common\Controllers\Brixy_Init_Controller;

class Product_Options extends Brixy_Init_Controller{
	
	function __construct(){
		helper(['common']);
	}
	function add_option(){
		
		p('add product option');
	}
	
	function edit_option($id){
		
		p('edit product option with id ' . $id);
	}
}

To process an HTTP request from a custom controller, you must define its route.

 When need to use database operations models must be loaded.
