CodeIgniter-i18n

####Internationalization (i18n) for CodeIgniter 2.1+

Based on http://codeigniter.com/wiki/CodeIgniter_2.1_internationalization_i18n/

##HMVC modular extension

By default is using HMVC modular extension.

If you want use without HMVC:

• In core/MY_Lang.php delete:

  require APPPATH . "libraries/MX/Lang.php";

  class MY_Lang extends MX_Lang {

and uncomment:

//class MY_Lang extends CI_Lang {

• In core/My_Config.php delete:

  require_once APPPATH . "libraries/MX/Config.php";

  class MY_Config extends MX_Config {

and uncomment:

//class MY_Config extends CI_Config {

##Route

Add these lines to application/config/routes.php:

// URI like '/en/about' -> use controller 'about'
$route['^(en|de|fr|nl)/(.+)$'] = "$2";

// '/en', '/de', '/fr' and '/nl' URIs -> use default controller
$route['^(en|de|fr|nl)$'] = $route['default_controller']; 

##Creating languages files

You can add placeholders inside your strings. For instance, if you like to add the "username" to a string, you can by writing this lang string:

$lang['welcome'] = "Welcome, %s."; 

##Create Controller

<?php
class About extends CI_Controller {

	function index()
	{
		// you might want to just autoload these two helpers
		$this->load->helper('language');
		$this->load->helper('url');

		// load language file
		$this->lang->load('about');

		$this->load->view('about');
	}
}

/* End of file about.php */
/* Location: ./application/controllers/about.php */ 

##Create View

To fetch a lang line or add an anchor:

<p><?=lang('about.gender')?></p>

<p><?=anchor('music','Shania Twain')?></p> 

In case you use placeholders inside your language strings, you can use them like this:

<p><?php $username = "John Doe";
echo lang('welcome', NULL, $username)?></p>

This should appear like:

Welcome, John Doe.

Or like this:

<?php $username = "John Doe";
echo lang('welcome', 'username', $username)?>

This should appear like:

<label for="username">Welcome, John Doe.</label>

Get the current language:

<?php echo get_lang();?>

This should appear like:

en

##Notes

• You might need to translate some of CodeIgniter’s language files in system/language. Example: if you’re using the "Form Validation" library for French pages, translate system/language/english/form_validation_lang.php to application/language/french/form_validation_lang.php.

• Links to internal pages are prefixed by the current language, but links to files are not:

  site_url('about/my_work'); // http://mywebsite.com/en/about/my_work

  site_url('css/styles.css'); // http://mywebsite.com/css/styles.css

• Get the current language:

  $this->lang->lang(); // en

• Switch to another language:

  anchor($this->lang->switch_uri('fr'),'Display current page in French');
