Answer 1

I have written an in-depth blog "Zend\Form\Element\Select and Database-Values" about this topic. Basically though, this is what you have to do:
Basically all you have to do is Query the Database inside your Form for the Data. For this you need the DB-Adapter to be available inside your Form, which is done by Dependency-Injection. Since the DB-Adapter is required for your Form to function correctly, i'd suggest Setter-Injection.
Inside your getServiceConfig() do this:
return array('factories' => array(
'namespace-form-formname' => function($sm) {
$dbA = $sm->get('Zend\Db\Adapter\Adapter');
$form = new \Namespace\Form\Formname($dbA);
return $form;
}
));
This will inject the Zend\Db\Adapter\Adapter into your form, which should already be valid though other configuration. Then you need to modify your form code a little bit:
public function __construct(\Zend\Db\Adapter\Adapter $dbA) {
parent::__construct('form-name');
// Do the DB-Query here. You got the DB-Adapter
// http://zf2.readthedocs.org/en/latest/modules/zend.db.adapter.html
$selectArray = array(
'key' => 'value',
'key' => 'value',
'key' => 'value',
); // obviously, this is just a fake-$selectArray demonstrating
// what the output of your Queries should be
// Add your Form Elements here
// use $selectArray as value_options of your desired select element
}
And that's basically it. Sadly i can't give you an concrete example, as i've never worked with Zend\Db, but i assume this will get you started.
PS: In your controller, call the form like this:
$form = $this->getServiceLocator()->get('namespace-form-formname');

Try:
// add code on controller
$arrPortalId = array();
$results = array('1' => 'portal 1', '2' => 'portal 2', '3' => 'portal 3',); // this part change your database value
foreach ($results as $key => $val) {
$arrPortalId[$key] = $va;
}
$dataParams['portalId'] = $arrPortalId;
$form = new UserForm($dataParams);
<?php
namespace Register\Form;
use Zend\Captcha\AdapterInterface as CaptchaAdapter;
use Zend\Form\Form;
use Zend\Form\Element;
class UserForm extends Form
{
protected $portalTable;
public function __construct($params = array())
{ $name = isset($params['name'])?$params['name']:'';
parent::__construct('user');
$this->setAttribute('method', 'post');
$this->setAttribute('class', 'form-horizontal');
$this->add(array(
'name' => 'id',
'attributes' => array(
'type' => 'hidden',
),
));
$portalId = (isset($params['portalId']) && count($params['portalId']) > 0)?$params['portalId']:array();
$this->add(array(
'type' => 'Select',
'name' => 'portal_id',
'options' => array(
'label' => 'Portal',
'empty_option' => 'Seleccione un portal',
'value_options' => $portalId,
)
));
$this->add(array(
'name' => 'firstName',
'attributes' => array(
'type' => 'text',
),
'options' => array(
'label' => 'First Name',
),
));
$this->add(array(
'name' => 'lastName',
'attributes' => array(
'type' => 'text',
),
'options' => array(
'label' => 'Last Name',
),
));
$this->add(array(
'name' => 'login',
'attributes' => array(
'type' => 'text',
),
'options' => array(
'label' => 'Login',
),
));
$this->add(array(
'name' => 'password',
'attributes' => array(
'type' => 'password',
),
'options' => array(
'label' => 'Password',
),
));
$this->add(array(
'name' => 'password_repeat',
'attributes' => array(
'type' => 'password',
),
'options' => array(
'label' => 'password (repeat)',
),
));
$this->add(array(
'name' => 'email',
'attributes' => array(
'type' => 'text',
),
'options' => array(
'label' => 'Email',
),
));
$this->add(array(
'type' => 'Zend\Form\Element\Csrf',
'name' => 'csrf',
'options' => array(
'csrf_options' => array(
'timeout' => 600
)
)
));
$this->add( array(
'type' => 'Captcha',
'name' => 'captcha',
'options' => array(
'label' => 'Please verify you are human.',
'captcha' => array('class' => 'Dumb',
),
),
));
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Go',
'id' => 'submitbutton',
),
));
}
}
