我有一个奇怪的问题，我在Symfony中使用表单时无法调试。我有一个表格在很长一段时间内工作得很好，然后突然昨天它开始失败$form->isValid()检查但是没有使用$form->getErrors()或$form->getErrorsAsString()返回任何错误。然而，如果我在调用\Doctrine\Common\Utils\Debug::dump($request->request->get('reportsettingstype')之前使用$form->isValid()它通过了检查，则会有一个奇怪的转折。那么现在真正的问题是，如何回应请求数据会导致表单突然通过验证？
我包含控制器操作和表单类以供参考：
/**
* @Route("/admin/report/build", name="build_report")
* @param \Symfony\Component\HttpFoundation\Request $request
*/
public function generateReportAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$report = new \Save\ReportBundle\Entity\Report;
$form = $this->createForm( new \Save\ReportBundle\Form\Type\ReportSettingsType, $report );
$form->handleRequest($request);
//echo '<pre>'; \Doctrine\Common\Util\Debug::dump($request->request->get('reportsettingstype'), 2); echo '</pre>';
if( $form->isValid() ){
$data = $request->request->get('reportsettingstype');
if( $data['newReport'] == 1){
$date = new \DateTime(date('m/d/Y', time()));
$client = $em->getRepository('SaveClientBundle:Client')->find($data['client']);
$title = strtolower(str_replace(' ', '_', $client->getName()).'_'.$date->format('m-d-Y'));
$report->setDate($date);
$report->setTitle($title);
$report->setClient($client);
$order = $em->getRepository('SaveOrderBundle:Orders')->find($data['order']);
$report->setOrder($order);
if( array_key_exists('reportFilter', $data)){
$reportFilter = $em->getRepository('SaveClientBundle:ClientArea')->find($data['reportFilter']);
$report->setReportFilter($reportFilter);
}
$assessments = $this->_findAssessments( $report );
if( $assessments->count() === 0 ){
$this->get('session')->getFlashBag()->add('error', 'No assessments found for area '.$report->getReportFilter()->getName());

foreach($pages as $page){
$html .= $page->getPageHeader() . $page->getPageBody() . $page->getPageFooter();
}
}
//$html .= $report->getReportFooter();
return $this->render('SaveReportBundle:Default:reportview.html.twig', array('reportData' => $html, 'report'=>$report));

如果有任何其他信息有用，请告诉我，我会将其添加到此问题中，现在我无法解释为什么表单未通过$form->isValid()检查。
