Hi T.J. Crowder,
var jsonRequest = JSON.stringify(requestObject);
new Ajax.Request(baseUrl + '/usermsg/index/sendmessage', {
method: 'POST',
requestHeaders: {Accept: 'application/json'},
parameters: {json: jsonRequest},
// ...
In PHP:
$request = $this->getRequest();
$json = $request->getParam("json");
// HERE decode fails with data sended from chrome
$requestObject = $zendJson->decode($json, Zend_Json::TYPE_OBJECT);
With Chrome decoding fails too. Why? :\
