How to pass params from controller to Zend_Form? - zend-framework

Question

I know this question is already answered here. But this doesnt work for me.
The Form is generated by using the PluginLoader:
$formClass = Zend_Registry::get('formloader')->load('Payment');
$form = new $formClass(array('someval' => $my_arr));
Payment.php:
class Form_Payment extends Zend_Form
{
protected $_someval = array();
public function init()
{
$this->setAction('payment/save');
//....
$this->addElement('multiCheckbox', 'store_id', array('label' => 'Someval:', 'required' => true, 'multiOptions' => $this->getSomeval()))
}
public function setSomeval($someval) {
$this->_someval = $someval;
}
public function getSomeval() {
return $this->_someval;
}
}
As I can see the load method only returns the class name, so new $formClass(); is equal new Form_Payment() but why this isn't accept params?

Answer 1

Ok I found a way by myself. I was looking for a way to inject some params while my Zend_Form was initialised. It seems the only way for this is to pass the params to the constructor - which is executed before the init method.
class Form_Payment extends Zend_Form
{
private $_someval;
public function __construct(array $params = array())
{
$this->_someval = $params['someval'];
parent::__construct();
}
public function init()
{
$this->setAction('payment/save');
//....
$this->addElement('multiCheckbox', 'store_id',
array('label' => 'Someval:',
'required' => true,
'multiOptions' => $this->_someval // passed params now available
))
}
}

You can add custom function to your form class like
class Form_Payment extends Zend_Form
{
public function init()
{
$this->setAction('payment/save');
// and so on
}
public function doSome()
{
$this->setAction('other/action');
}
}
and call it after instanciating form in controller
$form = new $formClass();
$form->doSome();
