codeigniter gettext poedit php

Hi!

Simple tutorial how to use gettext in your codeigniter application.

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

2) Create language files structure as follows:

Code:

/application/language/locales/lv_LV/LC_MESSAGES/

where lv_LV your language

3) Configure poedit (http://goo.gl/zSyfz) (use codeigniter paths) and generate *.mo and *.po files using poedit and name them as "lang":

Code:

result: /application/language/locales/lv_LV/LC_MESSAGES/lang.mo and lang.po

4) Create new codeigniter helper /application/helpers/my_language_helper.php

Code:

<?php  if (!defined('BASEPATH')) exit('No direct script access allowed');
function set_translation_language($language){
    $lang_path = FCPATH.APPPATH.'language/locales';
    putenv('LANG='.$language.'.UTF-8');
    setlocale(LC_ALL, $language.'.UTF-8');
    bindtextdomain('lang', $lang_path);
    textdomain('lang');
}
?>

5) set helper in autoloader: /application/config/autoload.php

Code:

$autoload['helper'] = array(..., 'my_language');

6) Initialize translation with function. (You can also set language in cookie and set language in helper)

Code:

set_translation_language('lv_LV');

That's all! =]

I tried to find something like this all over the web, but found nothing.
So, I looked at default php gettext functions (http://www.php.net/manual/en/function.gettext.php) and it was so easy to make it work with them.

Hopefully that will be useful to someone..
