使用2个值或其他方法进行切换？

Question

我有两个变量："tl_language“和"filterLanguage”。现在我使用以下代码：

switch($GLOBALS['TL_LANGUAGE'])
                        {
                            case 'de':
                                if (!$entry->field('beschreibung')->value()){

                                    include ("includes/mediacenter_content_de.php");
                                }else{
                                    include ("includes/mediacenter_content_en.php");
                                }
                                break;
                            case 'en':
                                if (!$entry->field('beschreibung')->value()){

                                    include ("includes/mediacenter_content_en.php");
                                }else{
                                    include ("includes/mediacenter_content_de.php");
                                }
                                break;
                            case 'fr':
                                if (!$entry->field('beschreibung')->value()){

                                    include ("includes/mediacenter_content_fr.php");
                                }else{
                                    include ("includes/mediacenter_content_en.php");
                                }
                                break;
                            case 'nl':
                                if (!$entry->field('beschreibung')->value()){

                                    include ("includes/mediacenter_content_nl.php");
                                }else{
                                    include ("includes/mediacenter_content_en.php");
                                }
                                break;
                            default:
                                echo $entry->field('beschreibung_englisch')->value();
                                break;
                        }

                        ?>

现在我想添加一个过滤器，用户可以单独过滤语言。例如，如果tl_language是"de“，则显示细菌内容，或者如果filterLanguage是"de”，则显示德国内容。

现在，我正在尝试这样做：

    if($GLOBALS['TL_LANGUAGE'] =="de" or $cc_language == "de"){
    if (!$entry->field('beschreibung')->value()){

        include ("includes/mediacenter_content_de.php");
    }else{
        include ("includes/mediacenter_content_en.php");
    }
}
if($GLOBALS['TL_LANGUAGE'] =="en" or $cc_language == "en"){
     if (!$entry->field('beschreibung')->value()){

        include ("includes/mediacenter_content_en.php");
    }else{
        include ("includes/mediacenter_content_de.php");
    }
}

但它显示了双重内容。

我建议使用第三个变量。我假设$cc_language有更高的优先权。使用您的第一个代码。

$lang = ( isset($cc_language)  && !empty($cc_language) ) ? $cc_language : $GLOBALS['TL_LANGUAGE'];

switch( $lang ) {
