PHP Post Data Formatting - php

Question

As per the Eventbrite API v3 documentation, the preferred way to submit the data is as JSON. I am attempting to update via ExtJS grid simple organizer data. The changes are not being processed.
The solution is in MODX and the updateFromGrid.class.php looks like this:
class UpdateOrganizerFromGridProcessor extends modProcessor {
public function initialize() {
$data = $this->getProperty('data');
if (empty($data)) return $this->modx->lexicon('invalid_data');
$data = $this->modx->fromJSON($data);
if (empty($data)) return $this->modx->lexicon('invalid_data');
$this->id = $data['id'];
$this->params = array ();
// build JSON content for form submission...cooking key names
$this->formData = array (
'organizer.name' => $data['name'],
'organizer.description.html' => $data['description'],
'organizer.logo.id' => $data['logo_id'],
);
$this->formJSON = $this->modx->toJSON($this->formData);
$this->args = array('id' => $this->id, 'params' => $this->params);
return parent::initialize();
}
public function process() {
// call to main class to save changes to the Eventbrite API
$this->mgr_client = new Ebents($this->modx);
$this->output = $this->mgr_client->postData('organizers', $this->args, $this->formJSON);
$response = json_decode(json_encode($this->output), true);
return $this->outputArray($response);
}
}
return 'UpdateOrganizerFromGridProcessor';
The json output from the above is:
{"organizer.name":"Joe Organizer","organizer.description":"Joe is the Uberest Organizer."}
And my post function is:
//send data to Eventbrite
function postData($method, $args, $JSONdata) {
error_log("JSON Payload : " . $JSONdata);
// Get the URI we need.
$uri = $this->build_uri($method, $args);
// Construct the full URL.
$request_url = $this->endpoint . $uri;
// This array is used to authenticate our request.
$options = array(
'http' => array(
'header' => "Content-type: application/json\r\n"
. "Accept: application/json\r\n",
'method' => 'POST',
'content' => $JSONdata,
'header' => "Authorization: Bearer " . $this->token
)
);
// Call the URL and get the data.
error_log("URL: " . $request_url);
error_log("Content: " . $options['http']['content']);
$resp = file_get_contents($request_url, false, stream_context_create($options));
// parse our response
if($resp){
$resp = json_decode( $resp );
if( isset( $resp->error ) && isset($resp->error->error_message) ){
error_log( $resp->error->error_message );
}
}
// Return it as arrays/objects.
return $resp;
}
function build_uri($method, $args) {
// Get variables from the $args.
extract($args);
// Get rid of the args array.
unset($args);
// Create an array of all the vars within this function scope.
// This should be at most 'method', 'id' and 'data'.
$vars = get_defined_vars();
unset($vars['params']);
// Put them together with a slash.
$uri = implode($vars, '/');
if (!empty($params)) {
return $uri ."?". http_build_query($params);
}
return $uri;
}
The post is working however there is no update to the data and the response back is the original data set. What am I missing here?

Answer 1

I figured it out. It was an issue with a missing slash right before the query string. I also removed the JSON data payload and am submitting as form encoded. The final class is below:
class UpdateOrganizerFromGridProcessor extends modProcessor {
public function initialize() {
$data = $this->getProperty('data');
if (empty($data)) return $this->modx->lexicon('invalid_data');
$data = $this->modx->fromJSON($data);
if (empty($data)) return $this->modx->lexicon('invalid_data');
$this->id = $data['id'];
$this->params = array (
'organizer.name' => $data['name'],
'organizer.description.html' => $data['description'],
'organizer.logo.id' => $data['logo_id'],
);
$this->args = array('id' => $this->id, 'data'=> '', 'params' => $this->params);
return parent::initialize();
}
public function process() {
// call to main class to save changes to the Eventbrite API
$this->mgr_client = new Ebents($this->modx);
$this->output = $this->mgr_client->postData('organizers', $this->args);
$response = json_decode(json_encode($this->output), true);
return $this->outputArray($response);
}
}
return 'UpdateOrganizerFromGridProcessor';
