Forms symfony 1.4失败后从字段重置值

如何重置formfield值

action:
            $this->form = new $class();
            $this->form->bind($request->getParameter('signin'));
            if ($this->form->isValid())
            {
                $values = $this->form->getValues();
                            $this->redirect('@example');
                    }
            else
            {
                if ($this->form->hasGlobalErrors())
                    $this->errorclass = 'error';
            }
            $this->form->resetFormFields();
            return $this->renderPartial('ajax/example);

我有两个字段email和pw：希望在错误为空后重置它们

这不管用：（

有什么解决办法吗？

Thx关于

如果您的表单只有两个字段（email和pw），您可以简单地重新输入表单

else
{
  if ($this->form->hasGlobalErrors())
    $this->errorclass = 'error';
  $this->form = new $class();
}

如果您的表单有更多字段（不仅仅是email和pw），并且希望保留其他字段值，则可以删除email和pw值并绑定新表单

$values = $request->getParameter('signin');
$this->form->bind($values);
if ($this->form->isValid())
{
  $this->redirect('@example');
}
else
{
  if ($this->form->hasGlobalErrors())
    $this->errorclass = 'error';
  $values['pw'] = '';
  $values['email'] = '';
  $this->form = new $class();
  $this->form->bind($values);
}

$values = $request->getParameter('signin');
$this->form->bind($values);
if ($this->form->isValid())
{
  $this->redirect('@example');
}
else
{
  if ($this->form->hasGlobalErrors())
    $this->errorclass = 'error';
  $values['pw'] = '';
  $values['email'] = '';
  $this->form = new $class();
  $this->form->bind($values);
}
