Re: [fw-general] Extending Zend_View_Helper_Json

[Christoph Dorn]

See http://framework.zend.com/issues/browse/ZF-4134 for a similar issue. You can use: $this->getHelper('Json')->suppressExit = true; but you will have to add this wherever you use a new instance of the helper. Please add your comments to the ticket for another use-case. Christoph Jake McGraw wrote: Hello all, bit of a problem, not sure how to resolve it. We've developed a RESTful JSON API using Zend Framework MVC. The API makes heavy use of the Zend_View_Helper_Json object, each controller, which represents a separate resource does the following when its done processing: $this->_helper->json( $data ); All of this was fine and dandy, until it was decided that we need logging to record every request/response to the API. I setup a BaseController which logs the request during preDispatch. Now, my problem is that directly calling $this->_helper->json( $data ) sends the response and exits, so, postDispatch never occurs. I've tried to resolve this by extending Zend_View_Helper_Json as follows: class BaseHelperJson extends Zend_View_Helper_Json { public function json( $data, $keepLayouts = false ) { // ... Do some logging ... parent::json( $data, $keepLayouts ); } } Then during init() I tried replacing the Zend Json Helper with my own... public function init() { // Do some init... $this->_helper->removeHelper('json'); $this->_helper->addHelper(new BaseHelperJson()); // Whoops, how do I reference BaseHelperJson?? } This causes an error because addHelper() expects Zend_View_Helper_Abstract... regardless, I wouldn't know how to reference my custom helper as $this->_helper->json anyway. So my question: is there any way to resolve this using OOP or Zend MVC magic or will I have to go through each controller and replace $this->_helper->json with something that plays nice with the dispatcher? - jake -- Christoph Dorn http://www.ChristophDorn.com/
