wordpress-mu 2.6.5 多語系修正 plugins

以下程式碼是修補wordpress-mu對zh語系檔的設定，存成*.php放在mu-plugins資料夾下即可。

<?php
function fixed_mu_dropdown_languages( $output, $lang_files, $current ) {
  $flag = false;
  $output = array();

  foreach ( (array) $lang_files as $val ) {
    $code_lang = basename( $val, '.mo' );

    if ( $code_lang == 'en_US' ) { // American English
      $flag = true;
      $ae = __('American English');
      $output[$ae] = '<option value="'.$code_lang.'"'.(($current == $code_lang) ? ' selected="selected"' : '').'> '.$ae.'</option>';
    } elseif ( $code_lang == 'en_GB' ) { // British English
      $flag = true;
      $be = __('British English');
      $output[$be] = '<option value="'.$code_lang.'"'.(($current == $code_lang) ? ' selected="selected"' : '').'> '.$be.'</option>';
  } elseif ( $code_lang == 'zh_CN' ) { // 簡體中文
   $ce = 'Simple Chinese';
   $output[$ce] = '<option value="'.$code_lang.'"'.(($current == $code_lang) ? ' selected="selected"' : '').'>'.$ce.'</option>';
  } elseif ( $code_lang == 'zh_TW' ) { // 繁體中文
   $de = 'Traditional Chinese';
   $output[$de] = '<option value="'.$code_lang.'"'.(($current == $code_lang) ? ' selected="selected"' : '').'>'.$de.'</option>';
  } else {
      $translated = format_code_lang($code_lang);
      $output[$translated] =  '<option value="'.$code_lang.'"'.(($current == $code_lang) ? ' selected="selected"' : '').'> '.$translated.'</option>';
    }

  }

  if ( $flag === false ) { // WordPress english
    $output[] = '<option value=""'.((empty($current)) ? ' selected="selected"' : '').'>'.__('English')."</option>";
