Zend FlashMessenger

Question

遇到问题，不知道为什么会发生这种情况：

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，它失败并显示消息：

  

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

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

Answer 1

尝试将代码更改为：

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