Zend Framework Session: Locking and Unlocking Namespace
Zend Framework Session Step By Step Tutorial - Part 5: Session namespaces can be locked. What's that mean? When a namespace session is locked, we can not update or delete value of session. it will be read-only.
We can use lock() to lock namespace. Then, if want to check whether locked or not, use isLocked(). Look this sample:
public function loginFormAction()
{
$ns = new Zend_Session_Namespace('HelloWorld');
$ns->lock();
if (!$ns->isLocked()) {
if(!isset($ns->yourLoginRequest)){
$ns->yourLoginRequest = 1;
}else{
$ns->yourLoginRequest++;
}
}
$request = $this->getRequest();
$this->view->assign('request', $ns->yourLoginRequest);
$this->view->assign('action', $request->getBaseURL()."/user/auth");
$this->view->assign('title', 'Login Form');
$this->view->assign('username', 'User Name');
$this->view->assign('password', 'Password');
}
To unlock, you can use unLock() method.
$ns= new Zend_Session_Namespace('HelloWorld');
// marking session as read only locked
$ns->lock();
// unlocking read-only lock
if ($ns->isLocked()) {
$ns->unLock();
}
