class SelectByIdentityType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('id', 'entity', array(
'required' => false,
'class' => 'ArtelProfileBundle:Developer',
'property' => 'id',
'property_path' => '[id]', # in square brackets!
'multiple' => true,
'expanded' => true
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => null,
'csrf_protection' => false
));
}
/**
* #return string
*/
public function getName()
{
return 'select';
}
}
and action where I visible my developers
/**
* Finds and displays a Project entity.
*
* #Route("/{id}/show", name="admin_project_show")
* #Method({"GET", "POST"})
* #Template()
* #ParamConverter("entity", class="ArtelProfileBundle:Project")
*/
public function showAction($entity, Request $request)
{
//some logic
$developers = $profileRepository->findBySkillsAndTag($developer, $skill_form);
$form = $this
->createForm(
new SelectByIdentityType(),
$developers
)
->createView()
return array(
'entity' => $entity,
'form' => $form,
'developers' => $developers,
);
}
and if I check developer click SEND and then in the controller action which receives the POSTed data:
/**
* Send email for Developers.
*
* #Route("/{id}/send", name="admin_project_send_email")
* #Method({"GET", "POST"})
* #Template()
* #ParamConverter("entity", class="ArtelProfileBundle:Project")
*/
public function sendAction($entity, Request $request)
{
$em = $this->getDoctrine()->getManager();
$developer = $request->getSession()->get('developer');
$form = $this
->createForm(new SelectByIdentityType())
;
$form->bind($request);
if ($form->isValid()) {
$data = $form->getData();//$data['id'] I have 0
$ids = array();
foreach ($data['id'] as $developer) {
$ids[] = $entity->getId();
}
$request->getSession()->set('admin/foo_list/batch', $ids);
}
Why in $data['id'] I have 0 ??
and my template
{% for entity in developers %}
<tr>
<td>{{ form_widget(form.id[entity.id]) }}</td>
Any ideas ??

You can filter the entities displayed in an entity field by using the query_builder option. That way you can just normally render the whole form and you get a checkbox list of only the entities that your query returns. If you need to display it in a special way, you can override the form templates.
Unfortunately, as far as I know you can't use DQL or repository methods in the query_builder option. You have to write the query-builder code directly into the form definition.
An example:
$builder->add('id', 'entity', array(
'required' => false,
'class' => 'ArtelProfileBundle:Developer',
'multiple' => true,
'expanded' => true
'query_builder' => function($repo)
{
return $repo->createQueryBuilder('d')
->where('x = y');
}
));
