Zend getting database record false - php

Question

I have a link http://mywebsite.com/referral/dafa60b2b96c366e165be58649755742
With a parameter dafa60b2b96c366e165be58649755742
Was try to get that parameter to connect to database to get that user information, but it end up getting no object: Notice: Trying to get property of non-object in line.....
here's my code:
application.ini:
resources.router.routes.referralSelectProduct.route = "/referral/:url"
resources.router.routes.referralSelectProduct.defaults.controller = Index
resources.router.routes.referralSelectProduct.defaults.action = referral-select-product
resources.router.routes.referralSelectProduct.reqs.url = "[0-9a-zA-Z]+"
controller:
public function referralSelectProductAction()
{
$referral_url = $this->getRequest()->getParam('url');
$user = $this->_helper->model('Users')->fetchRowByFields(array('url' => $referral_url));
setcookie('referral_url', $referral_url, time() + 3600*24*30, '/');
}
model:
class Application_Model_DbTable_Users extends Sayka_Db_Table_Abstract{
protected $_rowClass = 'Application_Model_DbTable_Row_User';protected $_name = 'users';}
view:
<div id="content_bottom" class="content"><br/>
<h1>Select the product to refer your friend <span class="colorset_orange"><?php echo $this->user()->first_name; ?></span>.</h1>
<div><a class="refer_submit" href="?email=<?php echo $this->user()->email ?>&first_name=<?php echo $this->user()->first_name; ?>&last_name=<?php echo $this->user()->last_name; ?>" id="btn_free_download">Free Download</a></div>
<div><a class="refer_submit" href="#" id="btn_buy_now">Buy Now</a></div>
My view end up getting no object of that user in the database.

If i remember it correctly (for zend framework 1.*):
// Controller
...
$this->view->user = $this->_helper->model('Users')->fetchRowByFields(array('url' => $referral_url));
// View
echo $this->user->email;
Make sure that this $this->_helper->model('Users')->fetchRowByFields(array('url' => $referral_url)) returns you what you expect. var_dump it in controller
