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
         )) 
   }

}
