Support » Plugin: WP Native Dashboard » Infinite loop

  • The “locale” filter which calls the on_locale() function can raise an infinite loop, that makes the browser tab crash.

    A solution is to unhook the “locale” filter at the beginning of the on_locale() function, then rehook it before each “return” in the same function.
    Here is the amended function (in file wp-native-dashboard.php):

    
    	//setup the correct user prefered language
    	function on_locale($loc) {
    		// FG: To avoid an infinite loop
    		remove_filter('locale', array(&$this, 'on_locale'), 9999);
    
    		if($this->orig_locale === false) $this->orig_locale = $loc;
    		$skip = !$this->options->enable_login_selector && !$this->options->enable_profile_extension && !$this->options->enable_language_switcher && !$this->options->enable_adminbar_switcher;
    		if ((is_admin() && !$skip) || ($this->options->translate_front_adminbar && $this->user_agent_is_wp_native_dashboard)) {
    			if (function_exists('wp_get_current_user')) {
    				$u = wp_get_current_user();
    				if (!is_object($u) || $u->ID == 0) return $loc; //bugfix: for ajax based login's
    				if (!isset($u->wp_native_dashboard_language)) {
    					if ($loc)
    						$u->wp_native_dashboard_language = $loc;
    					else
    						$u->wp_native_dashboard_language = 'en_US';
    				}
    
    				if(($u->wp_native_dashboard_language != 'en_US') && !@file_exists(WP_LANG_DIR.'/' . $u->wp_native_dashboard_language.'.mo')) {
    					// FG: Rehook this function
    					add_filter('locale', array(&$this, 'on_locale'), 9999);
    					return $loc ? $loc : 'en_US';
    				}
    				// FG: Rehook this function
    				add_filter('locale', array(&$this, 'on_locale'), 9999);
    				return $u->wp_native_dashboard_language;
    			}
    		}
    		// FG: Rehook this function
    		add_filter('locale', array(&$this, 'on_locale'), 9999);
    		return $loc;
    	}
