Neue Klasse anlegen in: Classes/Domain/Session/SessionHandler.php

Einbinden

Im Controller:

/**
 * The session handler
 *
 * @var Tx_Rsysproductbase_Domain_Session_SessionHandler
 */
protected $sessionHandler = NULL;

/**
 * __construct
 *
 * @return
 */
public function __construct() {
    parent::__construct();
    // get an instance of the session handler
    $this->sessionHandler = t3lib_div::makeInstance('Tx_Rsysproductbase_Domain_Session_SessionHandler');
}

oder:

/**
 * injectSessionHandler
 *
 * @param Tx_Rsysquiz_Domain_Session_SessionHandler $sessionHandler
 * @return void
 */
public function injectSessionHandler(Tx_Rsysquiz_Domain_Session_SessionHandler $sessionHandler) {
    $this->sessionHandler = $sessionHandler;
}

Verwenden

if(!empty($sort)) {
    $this->sessionHandler->writeToSession(array('sort'=>$sort));
} else {
    $sort = $this->sessionHandler->restoreFromSession('sort');
}
