Language - How to structure a multilanguage site?

[eluser]Mauricio de Abreu Antunes[/eluser]
I'm coding a web site. He has 3 language choices: spanish, portuguese and english.
In CI user guide, it tells me to put my translations in application/language.
Ok, i did it. But i wanna translate form validation errors, like required or is_unique.
How do to this? How to avoid system/core/language/english files?

Thanks, bye!

Hi,
use this library - https://github.com/daylerees/ci-lang
it's for CI 2.1
With multilanguage articles, use an "index" table for an article (id, lang_id, date, status..), and subtables (id, article_id, title, content..) for language variations. With a function you can check what is the current selected language, and get the appropriate language article from the DB.
How to implement : http://maestric.com/doc/php/codeigniter_i18n

Thanks dude!
I have another problem: i told i wanna change my error messages in form_validation and labels (my HTML content is not in DB), titles, headers to another language like portuguese or spanish.

When you use set_rules the message is in english. How to change this?

[eluser]predat0r[/eluser]
If I understand you

language/english

site_lang.php // english language lines, $lang['page_title'] = 'Title';

language/spanish

site_lang.php // spanish lang lines, $lang['page_title'] = 'Dirección';

And with form validation, if you have specific files for each language in system/language, then it'll switch to the current language version, but to be hones i didn't try form_validation in my single multilang project

When do you have a error message for required field in spanish, what do you display?
Do you display it in english?

I use this: I place $this->load->lang('default', $this->user->default_language) [application/language/some_lang/default_lang.php] into MY_Controller,

and whenever I print something, I use lang('key'). Default_language can be selected by user, default is english.

For form_validation, place form_validation_lang.php into application/language/some_lang, because application folder is loaded before system.

Ok, but what about error messages?
When you miss your username at login, how to translate this message with config file?

Just create form_validation_lang.php in application/language/spanish/ folder, with the same variables as those are in form_validation_lang.php in system/language/english folder. If default language is spanish, it will automaticly pick up form_validation_lang from application/language/spanish/ folder.

But if those messages are your own, not from validation class, just use: if ($this->user->correct_login() === TRUE) { echo 'logged in'; } else { echo lang('invalid_login'); }

and create variable in default_lang.php called $lang['invalid_login'] = 'le derping'

Get it?

I'll try this, dude!
Thank you.

Obs.: user guide does not show this alternative.

I solved.
I did what you mean and i autoloaded all my language files depending on language.
Thanks!
