So the problem is that the language does not change base on a cookie value. </p> <p>this function should set the language value but it does not. it seems that no matter what i do i always get "ar" as a self::$currlang value. how can i correct this issue?</p> <pre><code>public function _set(){ if( $_COOKIE['defaultLang'] != '' ) { self::$currlang = $_COOKIE['defaultLang']; } else { //this is the default language self::$currlang = 'ar'; } } </code></pre> <p>here is my code</p> <p>thanks for your help :)</p> <pre><code>&lt;?php include('../langs/english.php'); include('../langs/arabic.php'); class Translator{ private static $strs = array(); private static $currlang = ""; public function _set(){ if( $_COOKIE['defaultLang'] != '' ) { self::$currlang = $_COOKIE['defaultLang']; } else { //this is the default language self::$currlang = 'ar'; } } public static function loadTranslation($lang, $strs){ if (empty(self::$strs[$lang])) self::$strs[$lang] = array(); self::$strs[$lang] = array_merge(self::$strs[$lang], $strs); } public static function setDefaultLang($lang){ self::$currlang = $lang; } public static function getDefaultLang(){ return self::$currlang; } public static function translate($key, $lang=""){ if ($lang == ""){ $lang = self::$currlang; } $str = self::$strs[$lang][$key]; if (empty($str)){ //$str = "$lang.$key"; $str = 'Language "'. $lang .

    1. COwhy is the current language a STATIC attribute of your class?! what's the point of a translator class if they all share the same language?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
