Question

I have a table as below:

items
-id (pk) AI
-user_id (fk) references users
-title
-description

I have a form page which requires authenticated users. I want to fill the select box with items that belongs to the user (like select * from items where user_id=loggedinUserId)

I looked at the documentation and I found this:

 $builder->add('items', 'entity', array(
    'class' => 'AcmeHelloBundle:Items',
    'query_builder' => function(EntityRepository $er) {
       return $er->createQueryBuilder('i')
        ->orderBy('i.title', 'ASC');
    },
));

My question is how can I pass the authenticated user id to this query in symfony 2.1 forms ?

Answer 1

You have two possibilities:

• inject the parameters via the constructor (Constructor Injection)
• inject the parameters via the options of the form

This awesome thread show you an interesting way of doing it (from @khepin). However, as suggested by @Bernhard (see first comment), there is a simpler way in that case.

METHOD 1- Constructor Injection : If you can’t bother creating a suscriber etc… you can directly inject the security context into your form constructor :

ItemType:

namespace Acme\HelloBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Security\Core\SecurityContextInterface;
use Symfony\Component\Security\Core\User\UserInterface;

classItemType extends AbstractType
{
    /**
     * @var string
     */
    private $class;

    /**
     * @var UserInterface
     */
    private $user;

    /**
     * @param string $class
     */
    public function __construct($class, SecurityContextInterface $securityContext)
    {
        $this->class = $class;
        $this->user = $securityContext->getRequest->getUser();
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {

                $username = $this->user->getUsername();    

                $builder->add('items', 'entity', array(
                    'class' => $this->class,
                    'multiple' => true,
                    'expanded' => true,
                    'query_builder' => function(EntityRepository $er) use ($username) {
                        $query = $er->createQueryBuilder('i')
                            ->select(array('i'))
                            ->leftJoin('i.users', 'u')
                            ->andWhere('u.username = :username')
                            ->setParameter('username', $usename)
                            ->orderBy('i.title', 'ASC');

                        return $query;

                    },
                )
            ));

    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => $this->class,
        ));
    }

    public function getName()
    {
        return 'acme_hello_item';
    }
}

Declare it as a service:

<parameters>
    <parameter key="acme_hello.item.class">Acme\HelloBundle\Entity\Item</parameter>
</parameters>

<services>
    <service id="merk_notification.filter.form.type" class="Acme\HelloBundle\Form\Type\ItemType">
        <tag name="form.type" alias="acme_hello_item" />

        <argument>%acme_hello.item.class%</argument>
        <argument type="service" id="security.context" />
    </service>
</services>

To build your form, you can now do :

    $formBuilder = $this->container->get('form.factory');
    $form = $formBuilder->createNamed('acme_hello_item', 'acme_hello_item');
