Sequence of declaring a model variable in Zend Framework 2 - php

Question

I am a beginner of Zend Framework2. Following the example of "Zend Framework 2.0 by Example Beginner's Guide" I got stuck in a weird problem.
Here is my project structure.
I have a simple function creatureUser() in RegisterController.php:
<?php
namespace Users\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Users\Form\RegisterForm;
use Users\Form\RegisterFilter;
use users\Model\User;
use Users\Model\UserTable;
class RegisterController extends AbstractActionController
{
public function indexAction()
{
//$form = new RegisterForm();
$form = $this->getServiceLocator()->get('RegisterForm');
$viewModel = new ViewModel(array('form' => $form));
return $viewModel;
}
public function confirmAction()
{
$viewModel = new ViewModel();
return $viewModel;
}
public function processAction()
{
if (!$this->request->isPost()) {
return $this->redirect()->toRoute(NULL , array(
'controller' => 'register',
'action' => 'index'
));
}
$post = $this->request->getPost();
//$form = new RegisterForm();
//$inputFilter = new RegisterFilter();
//$form->setInputFilter($inputFilter);
$form = $this->getServiceLocator()->get('RegisterForm');
$form->setData($post);
if (!$form->isValid()) {
$model = new ViewModel(array(
'error' => true,
'form' => $form,
));
$model->setTemplate('users/register/index');
return $model;
}
// Create user
$this->createUser($form->getData());
return $this->redirect()->toRoute(NULL , array(
'controller' => 'register',
'action' => 'confirm'
));
}
protected function createUser(array $data)
{
$user = new User();
$sm = $this->getServiceLocator();
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new \Zend\Db\ResultSet\ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new \Users\Model\User);
$tableGateway = new \Zend\Db\TableGateway\TableGateway('user', $dbAdapter, null, $resultSetPrototype);
//$user = new User();
$user->exchangeArray($data);
$userTable = new UserTable($tableGateway);
$userTable->saveUser($user);
return true;
}
}
When run the above code I get an error:
Fatal error: Class 'users\Model\User' not found in C:\WebApp\ZF2Skeleton\module\Users\src\Users\Controller\RegisterController.php on line 90.
But If I move $user = new User(); below. Like this one:
protected function createUser(array $data)
{
$sm = $this->getServiceLocator();
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new \Zend\Db\ResultSet\ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new \Users\Model\User);
$tableGateway = new \Zend\Db\TableGateway\TableGateway('user', $dbAdapter, null, $resultSetPrototype);
$user = new User();
$user->exchangeArray($data);
$userTable = new UserTable($tableGateway);
$userTable->saveUser($user);
return true;
}
It will work perfectly. Can anyone tell me how this happens, please? Is it a sequence problem? Thank you!

It's a simple typo in your controller:
use users\Model\User;
should be:
use Users\Model\User;
(note the capital 'U' in 'Users').
