Каков наилучший способ отображения «флеш-сообщений» в kohana v3?

Вы имеете в виду, как переменные сеанса сеанса Kohana 2.x?

Последняя get_once() Kohana поддерживает get_once() которая очень похожа на старые переменные сеанса get_once() .

 $session = Session::instance(); $session->set('test', 'Hello, World!'); // The session variable is returned and removed. $test = $session->get_once('test'); 

Я думаю, что get_once – отличная функция, но что, если вы хотите, чтобы данные фактически были отделены от обычных данных, вот базовый класс, который перегружает «Сессию», чтобы вы могли использовать вызовы flashdata стиля «codeigniter» с любым хранилищем данных ,

Я понимаю, что был ответ на этот вопрос, и, как я уже говорил, метод get_once велик, и все, но я люблю сборку мусора намного больше.

Если у вас есть какие-либо улучшения в этом коде, дайте мне знать, это было здорово для меня до сих пор.

Посмотрите на этот модуль, это может быть то, что вы ищете https://github.com/daveWid/message

На этот раз я написал действительно простой класс. Проверьте это ниже. Примеры использования ниже

 class Notice { private static $session; private static $initialized = false; // current notices private static $notices = array(); function __construct() { } static function init() { self::$session = Session::instance(); self::$notices['current'] = json_decode(self::$session->get_once('flash')); if(!is_array(self::$notices['current'])) self::$notices['current'] = array(); self::$initialized = true; } static function add($notice, $key=null) { if(!self::$initialized) self::init(); if(!is_null($key)) { self::$notices['new'][$key] = $notice; } else { self::$notices['new'][] = $notice; } self::$session->set('flash', json_encode(self::$notices['new'])); return true; } static function get($item = null) { if(!self::$initialized) self::init(); if($item == null) { return self::$notices['current']; } if(!array_key_exists($item, self::$notices['current'])) return null; return self::$notices['current'][$item]; } } 

Примеры (если этот класс сохранен как APPPATH . 'classes/notice.php' ):

 Notice::add('Something great has happened!'); Notice::add('Exciting! I\'ve got something to tell you!', 'message'); echo Notice::get('message'); // "Exciting! I've got ..." foreach(Notice::get() as $message) { echo $i++ . $message .'<br />'; } 

EDIT: смешно … почему-то этот вопрос появился где-то, не заметил, что это действительно старый … извините за это!
