Internationalization (i18n) library for CodeIgniter

It is a simple internationalization (i18n) for CodeIgniter 2.2.X

What do we do different from the original project?

The original project shows an error if text doesn't contain a translated text. 
In this, we present the raw text informed if translated text not found.

Requirements

• CodeIgniter 2.2.X
• Enable Session

What it does

Have the language field in the URL, example:

• http://xxx.com/?lang=en-us
• http://xxx.com/index.php/welcome/index?lang=en-us

Installation

1. Copy application/config/language.php to your_app/application/config/
2. Copy application/core/MY_Lang.php to your_app/application/core/

Configuration

Open application/config/language.php file:

• language_field

You can find this field in URL, default value is "lang", example: xxx.com/?lang=zh-tw

• language_default_key

Default language you want to output.

• language_list

The language array lists you can support.

key: defined from $_['HTTP_ACCEPT_LANGUAGE']
value: corresponding to your language folder.

The language class will add prefix value on all language array key automatically.

Example:

about_lang.php => key: about.xxxx
api_lang.php => Key: api.xxxx

Enable language helper at application\config\autoload.php:

$autoload['helper'] = array('language');

How to use

Create a language file at application/language/english/about_lang.php:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$lang['home'] = "Home";
$lang['introduction'] = "Introduction";
$lang['location'] = "Location";

Controller

Load language file at constructor:

class About extends CI_Controller {
	
	public function __construct()
    {
		parent::__construct();

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

At view:

<?php
// Language_helper needed (deprecated)
echo lang('about.home');
echo lang('about.introduction');
echo lang('about.location');
echo lang('Text not translated');

echo $this->lang->line('about.home');    
echo $this->lang->line('about.introduction');    
echo $this->lang->line('about.location');    
echo $this->lang->line('Text not translated');
