Populate selectable field from DB in Zend 2 Album example - php

Question

I'm starting programming with Zend and I am using the default Album example they provide as a "getting started" guide.
I would like to have a select drop down field in the form, but I can't find an easy way of doing it like the code is right now
This is how I'm doing it without consulting DB from my UsersForm.php
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'name' => 'level',
'options' => array(
'label' => 'User level',
'value_options' => array(
'1' => 'admin',
'2' => 'boss',
'3' => 'assistent',
'4' => 'client',
),
),
));
UPDATE
Ok, so following that tutorial using TableGateway I managed to have a selectable but is grabbing data from the 'project' table because the rest of my fields need that table, but I need that selectable to get from 'user' table.
My Module.php looks like this:
public function getServiceConfig()
{
return array(
'invokables' => array(),
'factories' => array(
'Project\Model\ProjectTable' => function($sm) {
$projectTableGateway = $sm->get('ProjectTableGateway');
$usersTableGateway = $sm->get('UsersTableGateway');
$table = new ProjectTable($projectTableGateway, $usersTableGateway);
return $table;
},
'project-model-selectable' => function($sm) {
$tableGateway = $sm->get('selecttable-gateway');
$table = new SelectTable($projectTableGateway, $usersTableGateway);
return $table;
},
'ProjectTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Project());
return new TableGateway('project', $dbAdapter, null, $resultSetPrototype);
},
'UsersTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Users());
return new TableGateway('user', $dbAdapter, null, $resultSetPrototype);
},
'selecttable-gateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new SelectOption());
return new TableGateway('user', $dbAdapter, null, $resultSetPrototype);
},
),
);
}
And my getProject function in ProjectTable.php:
public function getProject($id)
{
$id = (int) $id;
$rowset = $this->projectTableGateway->select(array('id' => $id));
$row = $rowset->current();
if (!$row) {
throw new \Exception("Could not find row $id");
}
return $row;
}
My addAction in ProjectController.php
public function addAction()
{
$tableGateway = $this->getServiceLocator()->get('Project\Model\ProjectTable');
$form = new ProjectForm($tableGateway);
$form->get('submit')->setValue('Nuevo');
$request = $this->getRequest();
if ($request->isPost()) {
$project = new ProjectForm($tableGateway);
$form->setInputFilter($project->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$project->exchangeArray($form->getData());
$this->getProjectTable()->saveProject($project);
// Redirect to list of projects
return $this->redirect()->toRoute('project');
}
}
return array('form' => $form);
}
Thanks

public function getProject($id)
{
$id = (int) $id;
$rowset = $this->projectTableGateway->select(array('id' => $id));
$row = $rowset->current();
if (!$row) {
throw new \Exception("Could not find row $id");
}
return $row;
}
