validation errors multi-lingual

[eluser]sl3dg3hamm3r[/eluser]
here a corrected script which worked for me (based on Xwero's script, which had some errors concerning $this, maybe I tried it in a wrong context):

Code:

$CI =& get_instance();
if($lang != $CI->config->item('language'))
{
    $CI->config->set_item('language',$lang);
    $loaded = $CI->config->is_loaded;
    $CI->config->is_loaded = array();
            
    foreach($loaded as $file)
    {
        $CI->config->load(str_replace('_lang.php','',$file));    
    }
}

I wrote a small helper. A better way might be to inherit the Config-class and add this specialized function, but I was lazy...
