PhalconPHP: How to set a Selected option in SELECT tag

Question

I want to set the <option> with the value coming from Db. So far I tried this but not working:

$site_select = new Select('site_id', $this->_sites);

Answer 1

Update

Generating the select using DB columns as Timothy recommended:

new Select('site_id', Sites::find(), array('using' => array('site_id', 'site_name')));

Setting the selected value of the given select:

$site_select->setDefault('YOUR_DB_VALUE');

However there is another lovely trick about Phalcon forms. You could pass your DB entity to the form class and your form will be auto populated.

Form:

class YourFormClass extends Phalcon\Forms\Form
{
    public function initialize($entity = null, $options = null)
    {

Controller:

$entity = YourModel::findFirst();
$form = new YourFormClass ($entity, $options);

Note that Form input names must match DB/Model columns.
