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?
