Multiple hydrator usage

gistfile1.txt

class CreateForm extends \Zend\Form\Form
{
    public function __construct()
    {
        parent::__construct('create_address');

        $this->setAttribute('method', 'post')
             ->setHydrator(new ClassMethodsHydrator())
             ->setInputFilter(new InputFilter());

        // It would be interesting to have validation group per fieldset instead of per form, as it would allow to completely reuse
        // fieldset accross different forms
        $address = new AddressFieldset();
        $address->setUseAsBaseFieldset(true);
        $this->add($address);

        $this->add(array(
            'name' => 'submit',
            'attributes' => array(
                'type' => 'submit'
            )
        ));
    }


WHERE ADDRESSFIELDSET :

class AddressFieldset extends Fieldset implements InputFilterProviderInterface
{
    public function __construct()
    {
        parent::__construct('address');
        $this->setHydrator(new ClassMethodsHydrator())
             ->setObject(new \Application\Entity\Address());

        $street = new \Zend\Form\Element('street');
        $street->setAttributes(array(
            'type' => 'text',
            'label' => 'Street'
        ));

        $city = new \Application\Form\CityFieldset;
        /*$city->setAttributes(array(
            'label' => 'City'
        ));*/

        $this->add($street);
        $this->add($city);
    }

    /**
     * Should return an array specification compatible with
     * {@link Zend\InputFilter\Factory::createInputFilter()}.
     *
     * @return array
     */
    public function getInputFilterSpecification()
    {
        return array(
            'street' => array(
                'required' => true,
            )
        );
    }
}


City Fieldset and Country Fieldset as built the same way (but with different object given to setObject function).

The view :

<?php
    $address = $form->get('address');
    echo $this->formRow($address->get('street'));

    $city = $address->get('city');
    echo $this->formRow($city->get('name'));
    echo $this->formRow($city->get('zipCode'));

    $country = $city->get('country');
    echo $this->formRow($country->get('name'));
    echo $this->formRow($country->get('continent'));
?>



Controller :

$form = new \Application\Form\CreateForm();
            $address = new \Application\Entity\Address();
            $form->bind($address);
            $form->setBindOnValidate(false);

            if ($this->request->isPost()) {
                $form->setData($this->request->getPost());

                if ($form->isValid()) {
                    var_dump($address);
                }
            }


$address is :

object(Application\Entity\Address)[597]
  protected 'street' => string 'zeg' (length=3)
  protected 'city' => 
    object(Application\Entity\City)[583]
      protected 'name' => string 'grt' (length=3)
      protected 'zipCode' => string 'ferg' (length=4)
      protected 'country' => 
        object(Application\Entity\Country)[589]
          protected 'name' => string 'rthr' (length=4)
          protected 'continent' => string 'hthty' (length=5)

You should read setBindOnValidate(true), sorry :).
