Dynamically set SELECT attribute in zend2 - zend-framework2

Question

What I am actually doing is, fetching a list of companies from the database and passing that to the form SELECT element.
So I created a Model file, which returns an array
//=== return an array of $ID => $name of companies to use in dropdown in reports form
public function getTotalResult($table, $type, $id) {
$this->table = $table;
$select = new Select();
$spec = new Where();
$spec->equalTo('status', 1);
if ($type == 'name') {
$spec->equalTo('id', $id);
}
$select->from($this->table);
$select->where($spec);
$resultSet = $this->selectWith($select);
//$resultSet->buffer();
return $resultSet;
}
public function resultList($table){
$results = $this->getTotalResult($table, '', '');
foreach ($results as $result) {
$this->id[] = $result->id;
$this->name[] = $result->name;
}
$result = array_combine($this->id, $this->name);
return $result;
}
Then I tested this in my Controller, which returned exactly what I wanted:
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use SpangelLogin\Model\Register; // <-- Add this import
use SpangelLogin\Model\companyList; // <-- Add this import
class RegisterController extends AbstractActionController
{
protected $registerTable;
protected $companyList;
public function getcompanyList()
{
if (!$this->companyList) {
$sm = $this->getServiceLocator();
$this->companyList = $sm->get('SpangelLogin\Model\companyList');
}
return $this->companyList;
}
public function indexAction()
{
//== get list of companies
$company_table = 'rs_company';
$sector_table = 'rs_sector';
$companiesList = $this->getcompanyList()->getName($company_table, 2);
}
}
So now I want this companiesList array passed in my form's Select Element. How can I achieve that. Here is my form in which I am using select.
use Zend\Form\Form;
use Zend\Form\Element;
class SectorReportForm extends Form
{
public function __construct($name = null)
{
// we want to ignore the name passed
parent::__construct('sectorreport');
$companiesArray = $this->companiesList();
$sectorsArray = $this->sectorsList();
$this->setAttribute('method', 'post');
$this->setAttribute('enctype','multipart/form-data');
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'name' => 'company',
'attributes' => array(
'id' => 'company',
'multiple' => true,
'options' => $companiesArray,
),
'options' => array(
'label' => 'Company',
),
));
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Upload',
'id' => 'submitbutton',
'class' => 'button violet right'
),
));
}
}

From a Design-Perspective, the best approach would be to handle this via Dependency-Injection. That sneaky little buzzword that confuses people so much, but actually is nothing more but to forward data between objects :P
General Dependency-Injection for Forms can be seen looking at the following answer, as well as my Blog article
How to get data from different model for select?
Zend\Form\Element\Select and Database-Values
If you do not want to go this approach, you can handle this at the Controller level, too.
$form = new My\Form();
$select = $form->get('selectCountries');
$model = new My\Countries();
$listData = $model->getCountriesAsArray();
$select->setValueOptions($listData);
I still advise you to go the different approach ;) Keeps the controllers more clean, too, which is always a good thing. Separation of concern!
