If anyone’s still using CakePHP v1.3 of this brilliant datasource which allows you to treat data on subscribers in MailChimp as if they were in a local model, I had to make a few changes to make it work with v1.3 of the MailChimp API.
function read($model, $queryData = array()) {
$url = $this->buildUrl('listMemberInfo', $queryData['conditions']['emailaddress']);
$response = json_decode($this->connection->get($url), true);
if(isset($response['errors'])&&$response['errors']>0) { //this is how errors are indicated
return false;
}
return $response['data']; //allows find('first') to return $response['data'][0]
}
