   Hi,

   In order to have an automatic detection of the visitor language, I'd like to be able to use the HTTP_ACCEPT_LANGUAGE header in the case of the first visit on the multilanguage site.

   At this moment, I use the following code:

   In the functions.php of my theme:

   if ( class_exists('WP_Multilingual') ) {
   
   function getAcceptedLanguage() {
      $languages = split(",", $_SERVER['HTTP_ACCEPT_LANGUAGE'] );
      $lang_q = Array();
      foreach( $languages as $aLang ) {
          $lang_array = split(";q=", trim( $aLang ) );
          $lang = trim( $lang_array[0] );
          if( !isset( $lang_array[1] ) )
              $q = 1;
          else
              $q = trim($lang_array[1]);
          $lang_q["$lang"] = (float)$q;
      }
      arsort($lang_q);
      //extra code for making the languages key indexed
      $i = 0;
      $lang_index = Array();
      foreach($lang_q as $lang => $q) {
          $lang_index[$i] = $lang; //add to a new array the index key/language
          $i++;
      }
   
      return $lang_index;
   } // end of 'getAcceptedLanguage()'
   
   $siteLanguages = array_keys(WP_Multilingual::AvaibleLanguages());
   $acceptedLanguages = getAcceptedLanguage();
   foreach ( $acceptedLanguages as $key => $value ) {
       $language_ = explode('-', $value);
       $primaryLanguage = $language_[0];
       if ( in_array($primaryLanguage, $siteLanguages) ) {
           $theLang = $primaryLanguage;
           break;
       }
   } // endforeach
   
   function woodpok_set_lang(){
   
       global $theLang;
   
       if ( !isset($_COOKIE['language']) ) {
   
           setcookie("language", $theLang, time()+3600*24*365, '/');
           $link = WP_Multilingual::LanguageLink($_SERVER['REQUEST_URI'], $theLang);
   
           header('Location: '.$link);
           exit;
   
       } // endif
   
   } // end of 'woodpok_set_lang()'
   add_action('init', 'woodpok_set_lang', 100);
   
   } // endif

   In "multilingal.php", in the function "QueryString", I added:

   if ( isset($_COOKIE['language']) ) $language = $_COOKIE['language'];

   before:

   $link = WP_Multilingual::LanguageLink($_SERVER['REQUEST_URI'], $language);

   In "multilingal.php", in the function "SetLocale", I added:

   if ( $language && $_COOKIE['language'] != $language ) {
       setcookie("language", $language, time()+3600*24*365, '/');
   } // endif

   after:

   $language = isset($_GET['language']) ? $_GET['language'] : substr(str_replace(get_option('home'), '', 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']), 1, 2) ;

   It work for me at this moment but I can't upgrade for now :'(

   Do you think it will be possible for you to implement something like this directly in your plugin?

   Many thanks in advance for your positive answer :-)

   Cheers,
   David

   OK, I just saw that (didn't update since my hack). It work fine.

   The use of the _COOKIE is simple: I'm french but (as developper), I want to test a new (version of a) brother in beta which is only available in english.

   The HTTP_ACCEPT_LANGUAGE is set to "en". When I visit my Multilingual Blog, it send me the page in english. I switch to french. With a cookie, next time I visit the blog, It'll still be in french.

   OK, not everybody use a brother in a language different of his mother language but I want to take in account this case.

   Thank for the "override" option any way, I can use a "non-hacked" version of your plugin.

   But, I would be nice to have an option (or hook) to force the language manually. What do you think of something like: add_action('wp_multilingual_setlocale' 'my_custom_setlocale');? ;-)

   Cheers,
   David
