可以在没有重定向的情况下使用FlashMessenger吗？

Question

我想知道它是否可以使用flash messenger而无需重定向？例如.登录失败后,我想继续显示表单,不需要重定向.

public function loginAction() {
  $form = new Application_Form_Login();

  ...

  if ($this->getRequest()->isPost() && $form->isValid($this->getRequest()->getParams())) {
    $authAdapter = new Application_Auth_Adapter($form->getValue('username'), $form->getValue('password'));
    if ($this->auth->authenticate($authAdapter)->isValid()) {
      ...
    } else {
      // login failed
      $this->flashMessenger->addMessage('Login failed. You may have entered an invalid username and/or password. Try again');
    }
  }

  $this->view->form = $form;
}

您可以使用$ this-> flashMessenger-> getCurrentMessages();无需重定向即可检索Flash消息; 例:

$this->view->messages = array_merge(
    $this->_helper->flashMessenger->getMessages(),
    $this->_helper->flashMessenger->getCurrentMessages()
);
$this->_helper->flashMessenger->clearCurrentMessages();
