Zend：获取ContentSwitch帮助程序时遇到的错误

Question

I'm working my way through "Zend Framework: A beginners guide" by Vikram Vaswani, and currently I am attempting to get the ContentSwitch action helper for serving up XML content, however I encounter the following error message:

Action Helper by name ContentSwitch not found

When trying the following in my init() function:

$contentSwitch = $this->_helper->getHelper('contentSwitch');

All the sources say that this should work... however, it does not. I am using Zend Framework 1.11.11. Has anyone encountered this problem before?

Thanks for your time!

Answer 1

There is no contentSwitch helper. It's contextSwitch: http://framework.zend.com/manual/en/zend.controller.actionhelpers.html#zend.controller.actionhelpers.contextswitch
