I am new to zend framework2.
I got the error.
An exception was raised while creating "UserTable"; no instance returned.
Please look my code.
Login\Model\UserTable.php
protected $tableGateway;
public function __construct(TableGateway $tableGateway)
{
$this->tableGateway = $tableGateway;
}
public function fetchAll()
{
$resultSet = $this->tableGateway->select();
return $resultSet;
}
Login\Module.php
public function getServiceConfig()
{
return array(
'factories' => array(
'UserTable' => function($serviceManager) {
$tableGateway = $serviceManager->get('UserTableGateway');
return new UserTable($tableGateway);
},
'UserTableGateway' => function ($serviceManager) {
$dbAdapter = $serviceManager->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(NULL);
return new TableGateway('user', $dbAdapter, NULL, $resultSetPrototype);
}
)
);
}
Login\src\Login\Controller\LoginController.php
public function getAction()
{
$serviceManager = $this->getServiceLocator();
$userTable = $serviceManager->get('UserTable');
$user = $userTable->fetchAll();
return $this->redirect()->toRoute('home', ['data' => $user]);
}
local.php
return array(
'db' => array(
'dsn' => 'mysql:dbname=album; host=localhost',
'username' => 'root',
'password' => 'root',
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter'
=> 'Zend\Db\Adapter\AdapterServiceFactory',
),
)
);
when I just redirect to home in getAction() in controller, it working fine.
I couldn't get solution for this.
can anyone help me out.
Thanks in advance.
NOTE: please comment, if you need more details.
I have a problem with inserting Records into a DB using Zend FrameWork 2.
There are no records saved into the DB when submitting the Form and also no Error Messages Appear, just the Confirmation Message telling me that it << Registered Successfully >>
Here is my code, thanks in advance:

return array(
'db' => array(
'driver' => 'pdo',
'dsn' => 'mysql:dbname=zf_app;host=localhost;port:8080',

What is the User in public function saveUser(User $user) ? You didn't use User file.
My application is a collection of POPO's and I'm trying to wire these POPO's up using the Zend Framework 2 Service Manager.
To illustrate my problem, take the following example:
$config = array(
'services' => array(
'my.app.serviceA' => new \My\App\Services\ServiceA(),
'my.app.serviceB' => new \My\App\Services\ServiceB(),
'my.app.manager.task' => new \My\App\Manager\TaskManager(),
),
);
My TaskManager class looks something like this:
class TaskManager {
protected $serviceA;
protected $serviceB;
public function setServiceA( \My\App\Service\ServiceA $serviceA )
{
$this->serviceA = $serviceA;
}
public function setServiceB( \My\App\Service\ServiceB $serviceB )
{
$this->serviceB = $serviceB;
}
}
As you can see, the TaskManager class has dependencies on both ServiceA and ServiceB. How do inject those services into my.app.manager.task using the Service Manager configuration using the service names defined for both ServiceA and ServiceB?
UPDATE:
I'm beginning to believe that I shouldn't be using the ServiceManager component for my purposes at all but that I should be using the Zend DI component instead.
I get the impression that the ServiceManager is a ZF2 "framework" component whereas Zend\DI seems to be more of a generic all purpose DiC. Hence, this might be the reason of ServiceManager's tied relationship with the MVC and ModuleManager components (which also seem to be "framework" components).
Maybe someone could clarify?
in module.config.php The Service Manager can be configured in 7 different ways:
return array(
// instantiate the class for you when needed
'invokables' => array(
'commentController' => '\Comment\Controller\CommentController';
),
// Aliasing a name to a known service name
'aliases' => array(
'Comment\Service' => 'commentService';
),
// configure the instance of the object
'factories' => array(
'commentController' => function ($sm) {
$locator = $sm->getServiceLocator();
$controller = $locator->get('commentController');
$controller->setCommentService($locator->get('Comment\Service'));
return $controller;
}
),
// register already instantiated objects
'services' => array(
'commentController' => new \Comment\Controller\CommentController(),
),
//factory instance that can create multiple services based on the name supplied to the factory.
'abstract_factories' => array(
'SomeModule\Service\FallbackFactory',
),
// initialize the service whenever service created
'initializers' => array(
function ($instance, $sm) {
if ($instance instanceof \Comment\Controller\CommentController){
$instance->setCommentService($sm->get('Comment\Service'));
}
}
),
// indicating whether or not a service should be shared
'shared' => array(
'commentController' => false,
),
);
and in Module.php
public function getControllerConfig() {
return array(
'factories' => array(
'commentController' => function ($sm) {
$controller = new \Comment\Controller\CommentController();
$locator = $sm->getServiceLocator();
$controller->setCommentForm($locator->get('commentForm'));
$controller->setCommentService($locator->get('commentService'));
return $controller;
}
)
);
}
and simple use in controller :
$commentService = $this->serviceLocator->get('Comment\Service');
you put this in getter or in init() method
ZF2's New Controller::init() :: phly, boy, phly
in Controller ;
$yourService = $this->getServiceLocator()->get('your_service_alias');
in View Helper :
you should send in from Module.php by constructor of viewHelper
public function getViewHelperConfig() {
return array(
'factories' => array(
'loginHelper' => function($sm) {
return new LoginHelper($sm);
}
)
}
in a calss
use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
public class UseCaseBO implements ServiceLocatorAwareInterface {
protected $serviceLocator;
public function setServiceLocator(ServiceLocatorInterface $serviceLocator) {
$this->serviceLocator = $serviceLocator;
}
public function getServiceLocator() {
return $this->serviceLocator;
}
// now instance of Service Locator is ready to use
public function someMethod() {
$table = $this->serviceLocator->get('your_service_alias');
//...
}
}
for me, the best way is to create a class factory and use the factoryInterface, like this :
return array(
'service_manager' => array(
'factories' => [
'Task' => 'Application\TaskFactory',
],
'invokables' => array(
'Task'=> 'Application\Task',
'ServiceA'=> 'Application\ServiceA',
'ServiceB' => 'Application\ServiceB'
)
),
);
And a factory class :
class TaskFactory implements FactoryInterface {
/** #var ServiceLocatorInterface $serviceLocator */
var $serviceLocator;
public function createService(ServiceLocatorInterface $serviceLocator) {
$sl = $this->serviceLocator = $serviceLocator;
// you can get your registered services
$serviceA = $sl->get('ServiceA');
$serviceB = $sl->get('ServiceB');
// You can build your class using the class loader
$task = new Application\Task();
// Or the Service Locator Again
$task = $sl->get('Task');
return $task;
}
}
You can implement the factory interface on your Task class. I prefer to have control on what I'm building.
Module :
public function getServiceConfig() {
return array(
'factories' => array(
// 'user' table-------------------------------------
'Album\Model\AlbumTable\dbtable=user' => function($sm) {
$tableGateway = $sm->get('UserTableGateway');
$table = new SignupTable($tableGateway);
return $table;
},
'UserTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Signup());
return new TableGateway('user', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
Now how can I call my ‘dbadapter’ in anywhere in the model while I need it for
new \Zend\Validator\Db\RecordExists(
array(
'table' => 'user',
'field' => 'username',
'adapter' => $dbadapter
)
)
please tell me the way to call adapter in anywhere.
-thanks.
Edit :
I followed this 'Get default zend db adapter in table model' thread and did the following in my ‘model’,
<?php
namespace Application\Model;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
use Zend\Validator;
class Signup implements InputFilterAwareInterface {
public $username;
protected $inputFilter;
protected $serviceLocator;
protected $dbAdapter;
public function getServiceLocator() {
return $this->serviceLocator;
}
public function setServiceLocator(Zend\ServiceManager\ServiceLocatorInterface $serviceLocator) {
$this->serviceLocator = $serviceLocator;
return $this;
}
public function exchangeArray($data) {
$this->username = (!empty($data['username'])) ? $data['username'] : null;
$this->password = (!empty($data['password'])) ? $data['password'] : null;
$this->email = (!empty($data['email'])) ? $data['email'] : null;
}
public function getArrayCopy() {
return get_object_vars($this);
}
public function setInputFilter(InputFilterInterface $inputFilter) {
throw new \Exception("Not used");
}
public function getInputFilter() {
$this->$dbAdapter = $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter');
if (!$this->inputFilter) {
$inputFilter = new InputFilter();
$inputFilter->add(array(
'name' => 'username',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'NotEmpty',
'options' => array(
'messages' => array(
\Zend\Validator\NotEmpty::IS_EMPTY => 'Username required',
),
),
),
new \Zend\Validator\Db\RecordExists(
array(
'table' => 'user',
'field' => 'username',
'adapter' => $this->dbAdapter,
)
)
),
));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
}
but I got this error,

Please help me to fix it.
Add:
use Zend\Db\Adapter\Adapter;
to the top of Controller\Plugin\UserAuth.php
and:
extends Adapter
after:
class UserAuth
in the same file. That will at least get you going in the right direction.
