Switching contents language in CodeIgniter

[eluser]Блум[/eluser]
I found a different and IMHO a very easy and harmless way to have a language segment in your URL (http://yoursite.com/en/news/54) without changing the config options. The good thing is that you do not have to have

Code:

$config['uri_protocol']    = "ORIG_PATH_INFO";

and

Code:

$config['enable_query_strings'] = TRUE;

in your config.

All you have to do is:
1. .htacces

Code:

RewriteEngine on
RewriteCond $2 !^(index\.php|images|robots\.txt|css)
RewriteRule ^(bg|en)?(.*)$ /index.php/$2 [L]

Where 'bgen' is list of the languages that you want in the URL, In this case I want 'en' and 'bg'. This one just skips the language from the query to index.php

2. In index.php (in the root of your project) define a constant from the language query in the URL before CI spread it away.

Code:

<?php
// language constant
$urlData = explode('/',$_SERVER['REQUEST_URI']);
if (strlen($urlData[1]) == 2) define ('LANG',$urlData[1]); else define ('LANG',false);
?>

So now you can use the current LANG constant everywhere in your project, and URI Class is working the same: On url: http://yoursite.com/bg/news/42

Code:

echo 'Lang:'.LANG."; ";
echo 'Article:'.$this->uri->segment(2);

will output 'Lang:bg; Article:42'.
