Load language file automatically

That is already done. :#

[quote author="cahva" date="1266795125"]Extending is really easy. Just add that MY_Controller controller as MY_Controller.php to libraries folder and then in your controllers you extend MY_Controller instead of Controller.[/quote]
Done all that but now I got a few problems.

I only need those for the header and footer, so I will try with the header to test this out.

When using load view:
- <?php echo lang('something'); ?> doesn't work.
- $something also doesn't work. I get an error like "Undefined variable: something" although it's in MY_Controller.php

When using parser:
- {something} doesn't work and I get an error like "Invalid argument supplied for foreach()"

Is there any other way to do this? I don't mind if it was hard but at least the texts in my header and footer shouldn't be repeated in every controller.
