表单类型I构建如下
<?php
namespace HearWeGo\HearWeGoBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class CompanySubmitTourType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name','text')
->add('startdate','datetime')
->add('enddate','datetime')
->add('discount','number')
->add('info','text')
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array('data_class'=>"HearWeGo\HearWeGoBundle\Entity\Tour"));
}
public function getName()
{
return 'company_submit_tour';
}
}
在处理它的控制器
/**
* @Route("/company/submit",name="company_submit")
*/
public function submitTourAction(Request $request)
{
$tour=new Tour();
$form=$this->createForm(new CompanySubmitTourType(),$tour,array('method'=>'POST','action'=>$this->generateUrl('company_submit')));
$repository=$this->getDoctrine()->getRepository('HearWeGoHearWeGoBundle:Destination')->findAll();
$dest_arr=array();
$form_check=$this->createFormBuilder($dest_arr,array('method'=>'POST','action'=>$this->generateUrl('company_submit')));
$i=0;
foreach ($repository as $item)
{
$i++;
$form_check->add('destination','checkbox',array('label'=>$item->getName()));
}
$form_check->add('submit','submit');
$form->handleRequest($request);
if ($request->getMethod()=='POST')
{
if ($form->isValid())
{
$em=$this->getDoctrine()->getEntityManager();
$em->persist($tour);
$em->flush();
return new Response("<html>".$tour->getName()." has been created!</html>");
}
}
return $this->render('HearWeGoHearWeGoBundle:Company:companySubmit.html.twig',array('form1'=>$form->createView(),'form2'=>$form_check->getForm()->createView()));
}
如您所见，我必须使用两种形式：
$form用于将数据持久保存到Tour实体
$form_check用于获取我数据库中Destination表中所有记录的列表，然后显示复选框，供用户选择多个目标选项
我希望当用户点击“提交”按钮时，在我的数据库的Tour表中创建一个新记录，并且已检查的Destination对象列表也在数据中保持不变
但是2个表单不能一次发送POST方法
我没有在CompanySubmitTourType中添加所有记录的名称是徒劳的，所以我现在不知道该怎么做，即使我将此行添加到表单类型
->add('destinations','entity',array('class'=>'HearWeGoHearWeGoBundle:Destination','property'=>'name'))
然后在Controller中用循环中的$form_check->add替换$form->add，它只显示一个下拉菜单，其中我只能选择一个，而不是像我想要的那样选择多个选项。所以请帮我解决。我想使用复选框允许用户选择多个选项
