zend-framework - 可以在不重定向的情况下使用 FlashMessenger 吗？

Question

我想知道是否可以在不重定向的情况下使用 Flash Messenger？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;
}

Answer 1

您可以使用 $this->flashMessenger->getCurrentMessages() 检索 Flash 消息而无需重定向；示例:

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