}

to populate forgnein key idMod and idCat i tried with this:

$mod = $this->getObjectManager()->getRepository('Vehicules\Entity\modele')->findAll();
                foreach ($mod as $m){

                    if($m->getNom()==$f['modele'] ){
                        $Vehicule->setIdmod($m->getIdmod()) ;
                        exit;
                    }
                }

but id doesn't work :/

Answer 1

Your issue is the form/entity hydration. You don't need to reinvent the wheel here as Zend\Form already takes care of getting the data in and out of a form.

Currently your form uses the default ArraySerializable hydrator, so when the form is validated and you fetch the data (using $form->getData()) you are given an array. What you want is a already populated Vehicule entity.

The DoctrineModule\Stdlib\Hydrator\DoctrineObject is a hydrator specifically for Doctrine. If you attach it as the hydrator to your form it will return hydrated entity.

To solve this you need to STOP creating the form using new

$form = new VehiculeForm($_objectManager);

Instead create it via the ServiceManager

$form = $this->getServiceLocator()->get('MyModule\Form\VehiculeForm');

Now create the form from a service factory; allowing the injection of the form dependencies, including the hydrator.

MyModule/Factory/Form/VehiculeFormFactory.php

namespace MyModule\Factory\Form;

use MyModule\Entity;
use MyModule\Form;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\ServiceManager\FactoryInterface;
use DoctrineModule\Stdlib\Hydrator;

class VehiculeFormFactory implements FactoryInterface
{
    public function createService(ServiceLocatorInterface $sl)
    {
        $objectManager = $sl->get('Doctrine\ORM\EntityManager');

        $form = new Form\VehiculeForm($objectManager);
        $vehicule = new Entity\Vehicule();

        // create the hydrator; this could also be done via the
        // hydrator manager but create here for the example
        $hydrator = new DoctrineObject($objectManager);

        $form->setHydrator($hydrator);
        $form->setObject($vehicule);

        // We can also take care of the input filter here too!
        // meaning less code in the controller and only
        // one place to modify should it change
        $form->setInputFilter($Vehicule->getInputFilter());

        return $form;
    }
}

Module.php

public function getFormElementConfig()
{
    return array(
        'factories' => array(
            'MyModule\Form\VehiculeForm' => 'MyModule\Factory\Form\VehiculeForm' // path to our new factory
        ),
    );
}

You can now get rid of your populate() method and allot of the controller code.

FooController.php

//...
protected function getVehiculeForm()
{
    return $this->getServiceLocator()->get('MyModule\Form\VehiculeForm');
}

public function addAction()
{   
    $request = $this->getRequest();
    $form    = $this->getVehiculeForm();

    if ($request->isPost()) {

        $form->setData($request->getPost());

        if ($form->isValid()) {
            $vehicule = $form->getData(); // returns the entity!

            if ($vehicule instanceof Vehicule) {
                /// Fully hydrated entity!
                var_dump($vehicule);
            }
        } 
    }
    //...
}
//...
