R – Zend_Auth and profile edit

zend-authzend-framework

After logging user in I make some operations on his account. After that I want to update his data held bu Zend_Auth. How can I update all data at once, and not one by one which I know how to do it?

Best Answer

Read the data from Auth_Storage, update it and save it back.

How does Zend_Auth storage work

It's supposed to work.

Here's the implementation of the Auth getIdentity function.

/**
 * Returns the identity from storage or null if no identity is available
 *
 * @return mixed|null
 */
public function getIdentity()
{
    $storage = $this->getStorage();

    if ($storage->isEmpty()) {
        return null;
    }

    return $storage->read();
}

Here's the implementation of the PHP Session Storage write and read functions:

/**
 * Defined by Zend_Auth_Storage_Interface
 *
 * @return mixed
 */
public function read()
{
    return $this->_session->{$this->_member};
}

/**
 * Defined by Zend_Auth_Storage_Interface
 *
 * @param  mixed $contents
 * @return void
 */
public function write($contents)
{
    $this->_session->{$this->_member} = $contents;
}

Are you sure you are loading the same instance of the Zend_Auth class?

Are you using

$auth = Zend_Auth::getInstance();

Maybe you are calling the write method after the getIdentity method?

Anyway, as I said before, what you are doing should work.

and finnaly - Auth_Controller` :)

class Users_AuthController extends Smapp_Controller_Action 
{   
    //sesssion
    protected $_storage;

    public function getStorage()
    {
        if (null === $this->_storage) {
            $this->_storage = new Zend_Session_Namespace(__CLASS__);
        }
        return $this->_storage;
    }

    public function indexAction()
    {
        return $this->_forward('login');
    }

    public function loginAction()
    {   
        $openId = null;
        if ($this->getRequest()->isPost() and $openId = ($this->_getParam('openid_identifier', false))) {
            //do nothing
        } elseif (!isset($_GET['openid_mode'])) {
            return; 
        }

        //$userService = $this->loadService('User');

        $userService = new Users_Service_User();

        $result = $userService->authenticate($openId, $this->getResponse());

        if ($result->isValid()) {
            $identity = $result->getIdentity();
            if (!$identity['Profile']['display_name']) {
                return $this->_helper->redirector->gotoSimpleAndExit('update', 'profile');
            }
            $this->_redirect('/');
        } else {
            $this->view->errorMessages = $result->getMessages();
        }
    }

    public function logoutAction()
    {
        $auth = Zend_Auth::getInstance();
        $auth->clearIdentity();
        //Zend_Session::destroy();
        $this->_redirect('/');
    }
}

Question #2

keep it inside Zend_Auth.

after succesfull auth - write identity in storage. $auth->getStorage()->write($result->getIdentity());

the identity - is simply user_id

DB design

CREATE TABLE `user` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `open_id` varchar(255) NOT NULL,
  `role` varchar(20) NOT NULL,
  `last_access` datetime NOT NULL,
  `created_at` datetime NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `open_id` (`open_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8

CREATE TABLE `user_profile` (
  `user_id` bigint(20) NOT NULL,
  `display_name` varchar(100) DEFAULT NULL,
  `email` varchar(100) DEFAULT NULL,
  `real_name` varchar(100) DEFAULT NULL,
  `website_url` varchar(255) DEFAULT NULL,
  `location` varchar(100) DEFAULT NULL,
  `birthday` date DEFAULT NULL,
  `about_me` text,
  `view_count` int(11) NOT NULL DEFAULT '0',
  `updated_at` datetime NOT NULL,
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

some sugar

}

for things like this in any view script

 <?php if ($this->isAllowed('mvc:snippets.crud', 'update')) : ?>
    <a title="Edit &laquo;<?=$this->escape($snippetInfo['title'])?>&raquo; snippet">Edit</a>
 <?php endif?>
