Zend FlashMessenger

Question

遇到问题，不知道为什么会这样：

首先，一切正常，消息已设置并显示：

$this->_helper->FlashMessenger()
              ->setNamespace('success')
              ->addMessage('Success!')
              ->addMessage('User ' . $this->_request->getPost('user_name') . ' sucessfully added!');
$this->redirect('users/index');

但是，在这种情况下，它会失败并显示以下消息：

警告：缺少参数 1 Zend_Controller_Action_Helper_FlashMessenger::direct()

$this->_helper->FlashMessenger()
              ->setNamespace('error')
              ->addMessage('Failure!')
              ->addMessage('User was not added, please see errors below.');

Answer 1

尝试将您的代码更改为：

$this->_helper->getHelper('FlashMessenger')
              ->setNamespace('error')
              ->addMessage('Failure!')
              ->addMessage('User was not added, please see errors below.');
