Empty Zend_Auth::getInstance()->hasIdentity() - php

Question

i have a LoginController like this:
public function loginAction(){
$db = $this->_getParam('db');
$this->_helper->viewRenderer->setNoRender();
$this->_helper->getHelper('layout')->disableLayout();
$adapter = new Zend_Auth_Adapter_DbTable(
$db,
'user',
'username',
'password',
'MD5(CONCAT(?,password_salt))'
);
$adapter->setIdentity($this->_request->getParam('username'));
$adapter->setCredential($this->_request->getParam('password'));
$auth = Zend_Auth::getInstance();
$result = $auth->authenticate($adapter);
if ($result->isValid()) {
// get all info about this user from the login table ommit only the password, we don't need that
$userInfo = $adapter->getResultRowObject(null, 'password');
$users = new Application_Model_DbTable_Users();
$users->updateLastlogin($userInfo->email);
$auth->setStorage(new Zend_Auth_Storage_Session('testzf'));
$authStorage = $auth->getStorage();
$authStorage->write($userInfo);
$data = array('login'=>'success');
}
and a ProfileController:
public function getprofileAction(){
$this->_helper->viewRenderer->setNoRender();
$this->_helper->getHelper('layout')->disableLayout();
if(Zend_Auth::getInstance()->hasIdentity()) {
$username=$this->_request->getParam('username');
$db_users = new Application_Model_DbTable_Users();
$user = $db_users->getUser($username);
}
i made AjaxCalls for both Login and getprofile actions. I can login but getprofile doesn't work because Zend_Auth::getInstance()->hasIdentity() returns null.
I see 2 session files in the folder as in application.ini. resources.session.save_path = APPLICATION_PATH "/../data/sessions"
First one is full of session data, the second one is empty 0KB.
Should this work through Ajax-Calls or i make an Error?
Regards

Since you've used a custom auth storage key in your login action (testzf), you'll need to set this whenever you want to access the auth data:
public function getprofileAction(){
$this->_helper->viewRenderer->setNoRender();
$this->_helper->getHelper('layout')->disableLayout();
$auth = Zend_Auth::getInstance();
$auth->setStorage(new Zend_Auth_Storage_Session('testzf'));
if($auth->hasIdentity()) {
$username=$this->_request->getParam('username');
$db_users = new Application_Model_DbTable_Users();
$user = $db_users->getUser($username);
}
}

Please use Zend_Auth_Storage_Session like
in your login action
// check ajax request
$result = array(
'error' => true,
'msg' => 'Something went wrong,please try again!'
);
if(!$this->_request->isXmlHttpRequest()){
$this->_helper->json->sendJson($result);
}
/**
* user authentication
*/
$authAdapter = new Zend_Auth_Adapter_DbTable(null,$this->_table_user);
$authAdapter->setIdentityColumn('user_name')
->setCredentialColumn('password');
$authAdapter->setIdentity($user_name)
->setCredential($password);
$select = $authAdapter->getDbSelect();
$select->where('status = ?',1);
$result = $authAdapter->authenticate($authAdapter);
/**
* user validate
*/
if($result->isValid()){
$userStorage = new Zend_Auth_Storage_Session('Zend_Auth_User','User_Storage');
$userData = $authAdapter->getResultRowObject();
$userStorage->write($userData );
$this->_helper->json->sendJson(array('error'=>false));
}
// in your profile action
/**
* you will get user session data through Zend_Auth_Storage_Session
* you can write this function in action controller you will get in your controller easily
like $this->_helper->json->sendJson(array('error'=>false));
*/
$userStorage = new Zend_Auth_Storage_Session('Zend_Auth_User','User_Storage');
$userData = $userStorage->read();
suppose you need to check hasIdentity()
you should use default Zend_Auth_Storage_Session like
$userStorage = new Zend_Auth_Storage_Session();
// default namespace for auth storage (with out any namespace)
you used any namespace for in Zend_Auth_Storage_Session like Zend_Auth_Storage_Session('testzf') you need to set storage in $auth instance like
$auth = Zend_Auth::getInstance();
$auth->setStorage(new Zend_Auth_Storage_Session('testzf'));
$auth->hasIdentity(); // you will get storage here
