问题 I have a template where I render a widget which contains a form: {{ render(controller('ApplicationDemoBundle:Demo:newWidget', {'demo' : entity })) }} The newWidgetAction calls a createAction: public function createAction(Request $request) { $entity = new Demo(); $form = $this->createCreateForm($entity); $form->handleRequest($request); if ($form->isValid()) { $em = $this->getDoctrine()->getManager(); $em->persist($entity); $em->flush(); return $this->redirect($this->generateUrl('demo_show',

问题 In my current project, I decided to create only one translatable File entity and reuse it for all image/document properties I have. For the translations, I uses Knp Doctrine Behaviors Translatable. So here is the code. The file class: class File { use ORMBehaviors\Translatable\Translatable; /** * @var integer * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ protected $id; public function __toString() { return (string)$this->id; } /** * Get id * *

问题 I have a form (still not finished and is missing many fields) that is handled as a wizard with steps, in which fields from multiple entities are handled. This is the form itself: public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add('tipo_tramite', 'entity', array( 'class' => 'ComunBundle:TipoTramite', 'property' => 'nombre', 'required' => TRUE, 'label' => "Tipo de Trámite", 'query_builder' => function (EntityRepository $er) { return $er->createQueryBuilder

问题 After updating to Symfony 2.3 from 2.1, there is a strange message when I am trying to create a form : Catchable Fatal Error: Argument 1 passed to msgr\ProfileBundle\Form\EventListener\AddNameFieldSubscriber::preSetData() must be an instance of Symfony\Component\Form\Event\DataEvent, instance of Symfony\Component\Form\FormEvent given in /xxxxxx/aaas/src/msgr/ProfileBundle/Form/EventListener/AddNameFieldSubscriber.php line 29 These are the usual suspects : ProfileType.php <?php namespace aaas

问题 Symfony renders an entity field type like a choice dropdown - a select , basically. However, the CSS framework that I'm using defines a sort of 'select' as a ul and li as the options. The Custom Field Type documentation gives no help on this scenario. I'm converting my code from manual HTML rendering of the form dropdown to symfony form's version using twig and form_widget() . However, I want a ul and li instead of a select . The manual way of creating my dropdown is: <ul class='dropdown-menu

问题 I am building a project in Symfony 2.3 using Twig. I want to add a class to the form row block. I am using a form theme file which contains: {% block form_row %} <div class="form-row"> {{ form_label(form) }} {{ form_widget(form) }} {{ form_errors(form) }} </div> {% endblock %} Now some of my form rows I want to add an extra class form-row-split . I can't figure out how to do this properly. The way I have it almost-working is: {% block form_row %} {% set attr = attr|merge({'class': 'form-row'

问题 My goal: I built a custom constraint in SYMFONY, I needed to pass a variable to that constraint. The context: The constraint do a check if a value is unique in the DB, if it is not, it raises a CONSTRAINT alert.
