* To translate something use function _('my text') in your controllers and views.

* Create language files structure as follows:

Code:

/application/language/locales/lv_LV/LC_MESSAGES/

where lv_LV your language[/quote]

--------------------------------------------------------------------------------------------------------------
* Can I use the lang() function bulit in CodeIgniter instead of _() function?
* Can I use the directory as following:

Code:

/application/language/english/

instead of

Code:

/application/language/locales/lv_LV/LC_MESSAGES/

If I can't, please give me some explanations. I have tried, but could not do that.

Thank You!
