Question

当我坚持实体时，我想在表单中添加一个按钮。那可能吗。我读了很多关于修改实体的内容，但这不是我想要做的，我只是想添加一个按钮。

if($form->isSubmitted() && $form->isValid()) {
   $em = $this->getDoctrine()->getManager();
   $em->persist($entity);
   .... what do I write here to add my button ? is it even here  or the type ?

谢谢 }

我找到了一个解决方案，它实际上是可能的。必须先创建formView，然后再检查表单是否已提交或有效

$form_builder->add('button', 'boutons', array('attr' => array('boutons' => $buttons)));   //boutons is a type field I created and I have to give an array of buttons I want to add)
$form = $form_builder->getForm();
$form->handleRequest($request);
$form_view = $form->createView();

if($form->isSubmitted() && $form->isValid()) {
    $em = $this->getDoctrine()->getManager();
    $entity = $form->getData();
    $em->persist($entity);

    if($form_view->offsetExists('button')) { 
         $form_view->children['button']->vars['attr']['boutons'][] = $button_send_validation; (// I add my new button to the array of buttons)
    }

}

希望它可以帮助别人..
