来自实体的symfony2表单

Question

好的，我正在使用symfony2，并且我试图在这个表单中创建一个基于另一个实体的选项框……

所以在我的控制器中，我有：

<?php

namespace Ecs\CrmBundle\Controller\Report;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Ecs\CrmBundle\Form\Report\TimeClockReportType;

class TimeClockReportController extends Controller
{
    public function indexAction()
    {
        $request = $this->get('request');
        $em = $this->getDoctrine()->getEntityManager();
        $start = null;
        $end = null;
        $dateRangeForm = $this->createForm(new TimeClockReportType());

        if ($request->getMethod() == 'POST')
        {
            $dateRangeForm->bindRequest($request);
            $formData = $dateRangeForm->getData();

            $start = $formData['dateRange']['startDate'];
            $end = $formData['dateRange']['endDate'];
        }

        return $this->render('EcsCrmBundle:Reports:TimeClockReport.html.twig', array(
            'start' => $start,
            'end' => $end,
            'form' => $dateRangeForm->createView(),
        ));
    }

}

我的TimeClockReportType.php看起来像这样：

    <?php

namespace Ecs\CrmBundle\Form\Report;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

use Ecs\CrmBundle\Form\Parts\DateRangeType;
use Ecs\CrmBundle\Form\Parts\DepartmentSelectionType;


class TimeClockReportType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder
            ->add('dateRange', new DateRangeType())
            ->add('salesCompany', new DepartmentSelectionType(true));
    }

    public function getName()
    {
        return 'ecs_crmbundle_TimeClockReportType';
    }

}

我的DepartmentSelectionType看起来像这样：

    <?php

namespace Ecs\CrmBundle\Form\Parts;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

class DepartmentSelectionType extends AbstractType
{
    private $canSeeAll = false;

    public function __construct($canSeeAll = false)
    {
        $this->canSeeAll = $canSeeAll;
    }

    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder
            ->add('department', 'entity',
                array(
                    'class' => "EcsAgentManagerBundle:EmployeeDepartment",
                    'required' => false,
                    'multiple' => true,
                    'expanded' => true,
                    'label' => "Department"))
        ;
    }

    public function getDefaultOptions(array $options)
    {
        return array(
            'data_class' => 'Ecs\AgentManagerBundle\Entity\EmployeeDepartment',
        );
    }

    public function getName()
    {
        return 'ecs_crmbundle_departmentselectiontype';
    }
}

我想出的问题是，我得到的只是一个空白的白屏...但是，如果我删除：

来自TimeClockReportType的->add('salesCompany', new DepartmentSelectionType(true))它工作得很好...但是我看不到任何错误或者为什么它不能工作..

空白页面表示发生了解析错误/引擎错误。我建议修改您的php.ini文件以启用display_errors。

之后请务必重新启动您的your服务器。
