我正在尝试获取选择表的结果。
形式是这样的：
$users = $em->getRepository('UserBundle:User')->findAll();
$form = $this->createFormBuilder($users)
->add('users', 'entity', array(
'label' => 'Pick that user',
'class' => 'UserBundle:User',
'choice_label' => 'usFirstname'))
->add('save', 'submit', array('label' => 'Submit'));
然后，我想让用户选择，我尝试了几种方法，但没有任何效果……应该是这样的：
$user_picked =
$em->getRepository('UserBundle:User')->
findBy(array('usFirstname' => $form->getForm()->get('users')->getData()));
单击“提交”按钮后，如何使用户被选中？
表单构建器的魔力为您完成了这项工作。
如果转储数据dump($form->get('users')->getData())，它将是表单中可供选择的用户实例。无需执行额外的查询。
此外，choice_label仅过滤选择选项文本中的内容，而不是值。
例子;
<?php
namespace AppBundle\Controller;
use AppBundle\Entity\User,
AppBundle\Form\MyFormType;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route,
Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter,

use Symfony\Component\HttpFoundation\Request,
Symfony\Bundle\FrameworkBundle\Controller\Controller;
class MyController extends Controller
{
public function addAction(Request $request)
{
$form = $this->createForm(new MyFormType(), null, []);
$form->add('submit', 'submit', [
'label' => 'Create',
'attr' => ['class' => 'btn btn-success pull-right']
]
);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
dump($form->get('users')->getData());
exit(0);
}
return $this->render('AppBundle:user:form.html.twig', [
'form' => $form->createView()
]
);
}
}
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType,

{

public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('users', 'entity', [

'choice_label' => 'usFirstname',
'expanded' => false,

}
