This plugin tries to collect and improve on a few multilingual plugins and tips that are floating around and collate them into a single plugin that provides a consistent interface for multilingual capabilities.

• Demo
• Installation
• Configuration
• Forum

You'll need to hack your template a little to get it to show the plugin's flags.

Without hacking your template too much, the cleanest way is to create a file in your template directory called /lib/tpl/_template_/show_languages.html

show_languages.html

<?php 
  $multi_lingual_plugin = &plugin_load('syntax','multilingual');
  if ( $multi_lingual_plugin ) {
    if ( !plugin_isdisabled($multi_lingual_plugin->getPluginName() ) ) {
      print $multi_lingual_plugin->_showTranslations();
    }
  }
?>

Note that the if conditions check first that the plugin both exists and is enabled - this allows your template to function, even if you do not currently have the plugin installed. Then add the following line somewhere in your template's main.php .

<?php @include(dirname(__FILE__).'/show_languages.html')?>

As admin, under the configuration settings page, there are some important configuration settings that are necessary to be configured before proceeding:

You can test the browser sniffing in Firefox by simply going to edit→preferences→advanced and choose a language other than your system language.

You can either use the forum above, or add below for any discussion about problems/requests you might have.

Also, I figured I wanted the user to be redirected to a language page instead of page not found when visiting the top site without explicitly specifying the language namespace. (ex : http://my.org/wiki/doku.php) The following code (should go before 'return true' in 'multilingual_ui') will look for browser preference language first and then list of enabled languages in this plugin and check if any of the language page exists and if it does, redirects there. This only redirects the top page, since it's hard to determine if the initial part of the namespace of other pages refers to a language or not. (Maybe unless it goes through the list of ISO codes.) But then again, other pages should be linked with language preference prepended. (This does not honor the RFC for 'Location' header by not being an absolute URL, but browsers do handle these anyway…)

  if($ID == $conf['start'])
   {
      array_unshift($enabled_languages, $conf['lang']);
 
      foreach(array_unique($enabled_languages) as $language)
      {
         if(file_exists("{$conf['savedir']}/pages/$language/$ID.txt"))
         {
            header("Location: {$_SERVER['PHP_SELF']}?id=$language:$ID");
            exit;
         }
      }
   }

Anyone using 'sidebar' template can create the sidebar page at 'en:sidebar' and the likes to have separate languages displayed for sidebars. Using 'indexmenu' inside the sidebar will also automatically limit the pages shown for that particular language as well.

To remove redundant 'start' link without language prefix (which switches back to the browser preferred language if above modification was done, even if the user is reading on another language than that) from the 'You are here' in the header, you can comment the following line in the 'function tpl_youarehere' in 'inc/template.php'.

// always print the startpage
tpl_pagelink(':'.$conf['start']);
