creating more than one extension to a core library class

[eluser]xwero[/eluser]
The MY_ prefix is to automatically load the extended library. I'm not sure if it will work but you can try to put the two extending classes in the MY_Input.php file and then you have to instantiate them yourself.

Code:

// MY_Input.php
class Input_one{}

class Input_two()
// controller
$input_one = new Input_one();
