This language class extension allows you to automatically prefix all site urls with a language abbreviation that is pre-defined in your config file or from a link and automatically load the corresponding language translation file, the route will then be corrected by the route regex for everything to work as normal.

Somewhere in the site you can provide the user with links allowing them to change their desired language name.

[h3]Extending url helper to display links to content in another language[/h3] Category:Helpers Category:Language If you want to display links to another languages for your content, you can extend url helper. Add to the config file a few lines like this: [code] //language descriptions $config['lang_desc']=array("es"=>"Versión en español", "en" => "English version", "gl" => "Versión en galego"); [/code]

Place this file in your application MY_url_helper.php [code] <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); /**

  • Alternative languages helper
  • Returns a string with links to the content in alternative languages
  • version 0.2
  • @author Luis luis@piezas.org.es */

function alt_site_url($uri = '') { $CI =& get_instance(); $actual_lang=$CI->uri->segment(1); $languages=$CI->config->item('lang_desc'); $ignore_lang=$CI->config->item('lang_ignore'); if (empty($actual_lang)) { $uri=$ignore_lang.$CI->uri->uri_string(); $actual_lang=$ignore_lang; } else { if (!array_key_exists($actual_lang,$languages)) { $uri=$ignore_lang.$CI->uri->uri_string(); $actual_lang=$ignore_lang; } else { $uri=$CI->uri->uri_string(); $uri=substr_replace($uri,'',0,1); } } $alt_url=''; foreach ($languages as $lang=>$lang_desc) {

     if ($actual_lang!=$lang)
     {
        $alt_url.='<a href="'.$CI->config->slash_item('base_url');
        if ($lang==$ignore_lang)
        {
            $new_uri=ereg_replace('^'.$actual_lang,'',$uri);
            $new_uri=substr_replace($new_uri,'',0,1);
        }
        else
        {
            $new_uri=ereg_replace('^'.$actual_lang,$lang,$uri);
        }
        $alt_url.=$new_uri;
        $alt_url.='">'.$lang_desc.'</a><br />';
     }
}
return $alt_url;

}

?> [/code] and you are ready to use it in your view files: [code]

<?php echo alt_site_url();?>
[/code] Now suppose that your default language is english and you are visiting, by example, the spanish version of your web http://example.com/es/mycontroller/myfunction/. This is what you will obtain: [code] [/code]

if u want to display images or text u can add to the config file

[code] //language use images $config['lang_useimg'] = true; //or false to use only text [/code]

change MY_url_helper.php to [code] <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); /**

function alt_site_url($uri = '') { $CI =& get_instance(); $actual_lang=$CI->uri->segment(1); $languages=$CI->config->item('lang_desc'); $languages_useimg=$CI->config->item('lang_useimg'); $ignore_lang=$CI->config->item('lang_ignore'); if (empty($actual_lang)) { $uri=$ignore_lang.$CI->uri->uri_string(); $actual_lang=$ignore_lang; } else { if (!array_key_exists($actual_lang,$languages)) { $uri=$ignore_lang.$CI->uri->uri_string(); $actual_lang=$ignore_lang; } else { $uri=$CI->uri->uri_string(); $uri=substr_replace($uri,'',0,1); } } $alt_url='
