javascript - symfony2 advanced select in form
Get the solution ↓↓↓
Solution:
I had the same problem. I use jQuery to get part of the collection (extra input fields). In controller I have form builder that creates and returns those inputs as HTML. You can add condition and pass parameters (I use POST and GET is only for testing) and get different collection.
/**
* @Route("/gcco/{id}", name="name", options={"expose"=true})
* @Method({"GET", "POST"})
*/
public function functionName($id){
$defaultData = array('message' => 'Type here');
$form = $this->createFormBuilder($defaultData, array('csrf_protection' => false));
$form->add('name', 'type', array(
'label' => 'label',
'label_attr' => array(
'title' => 'title',
),
'required' => false,
));
}
}
$form = $form->getForm();
$html = $this->renderView('YourBundle:Default:form.html.twig', array('form' => $form->createView()));
return new JsonResponse(
array(
'html' => $html
)
);
}
And in form.html.twig file add so you will get only input fields:
{{ form_widget(form) }}
In JsonResponse you will get your collection.
Maybe it's not the best way but it works for me every time.
Other way is to pass JSON back to JavaScript and build all inputs there.
