Web site with 2 Languages

[eluser]invision[/eluser]
Hi,

I've followed this brilliant Wiki guide on using Multiple Languages with CodeIgniter and can now visit www.site.com/en/ and www.site.com/es/ and get the same page loading. Brilliant

However, I now have some questions which I'd loooove to get an answer for.

1) How do I load a different navigation bar (a simple <div></div>) based on the current language (en/es/etc...) ? So it would load different language nav bar depending on the language the user chooses.

and

2) How do I retrieve different data (different columns) from my database based on the current language?
Would this require just loading a different set of methods from my Model/Controller?


Many thanks for any guidance with this.
