我想分离表单验证逻辑:
public function contactAction()
{
$form = $this->createForm(new ContactType());
$request = $this->get('request');
if ($request->isMethod('POST')) {
$form->submit($request);
if ($form->isValid()) {
$mailer = $this->get('mailer');
// .. setup a message and send it
return $this->redirect($this->generateUrl('_demo'));
}
}
return array('form' => $form->createView());
}
我想翻译成两个单独的动作:
public function contactAction()
{
$form = $this->createForm(new ContactType());
return array('form' => $form->createView());
}
public function contactSendAction()
{
$form = $this->createForm(new ContactType());
$request = $this->get('request');
if ($request->isMethod('POST')) {
$form->submit($request);
if ($form->isValid()) {
$mailer = $this->get('mailer');
// .. setup a message and send it using
return $this->redirect($this->generateUrl('_demo'));
}
}
// errors found - go back
return $this->redirect($this->generateUrl('contact'));
}
问题是当表单中存在错误时 - 在表单验证和重定向之后,不会显示在 contactAction 中。(重定向后它们可能已经被遗忘 - 错误上下文将丢失)
