Without knowing specifically what functionality is wanted by each individual using a function to add or update, it's hard to make one that would work for everyone. The function you pasted above was meant to complete replace the entire contacts information with the details that were submitted to that function. The one below does it's best to determine what details were actually submitted to this function and need to be updated by seeing if each field actual has a value other than null/empty.
In regards to the function turning back 'true' every time, this is because the addSubscriber() and editSubscriber() functions that this function uses are always turning those values back. This is something that we will look at resolving, but I do want to let you know that we are mainly planning on maintaining our PHP Library going forward, as opposed to these older samples.
Please let me know if you have any questions or concerns regarding this. Thanks.
public function addOrUpdate
($contactInfo) {
// Add the subscriber if they do not exist
if ($this->subscriberExists($contactInfo) == false){
// Create XML
$newContactXML = $this->createContactXML(null,$contactInfo);
// Add subscriber
$postReturn = $this->addSubscriber($newContactXML);
$response = ($postResponse ?
true: false);
} else {
// Get all information currently stored in Constant Contact
$currentDetails = $this->getSubscriberDetails($contactInfo);
foreach($contactInfo as $contactList){
/* Check if the contact is already subscribed to any of the lists they selected in the form */
if(!in_array($contactList, $currentDetails)){
// Append any newly selected lists to an array of previously subscribed lists
array_push($currentDetails, $contactList);
}
}
// Update necessary fields
foreach($contactInfo as $field => $value){
if($field != 'lists' && !empty($value)){
$currentDetails = $contactInfo;
}
}
//create the XML using updated details as well as the existing ID
$updateXml = $this->createContactXML($currentDetails, $currentDetails);
//Update the subscriber using the newly created XML
$putReturn = $this->editSubscriber($currentDetails, $updateXml);
$response = ($putReturn ?
true: false);
}
return $response;
}
