Question

Animation enter image description here

User enter image description here

I'm trying to retrieve the user id for the creator of the animation object as below. When I echo $userID I see an array - looks like it's a pointer to the user object. How do I get the username from the user object?

Or would I be better saving the user id as a string in the animation class when I create the animation object?

$query = new ParseQuery("Animation");
$query->descending("createdAt");
$query->limit(2);
$results = $query->find();


for ($i = 0; $i < count($results); $i++) { 
  $object = $results[$i];
  $file = $object->get("gifFile");
  $url = $file->getURL();
  $userID = $object->get("createdBy");

Here's a dump of $userID

Parse\ParseUser Object ( [_sessionToken:protected] => [serverData:protected] => Array ( ) [operationSet:protected] => Array ( ) [estimatedData:Parse\ParseObject:private] => Array ( ) [dataAvailability:Parse\ParseObject:private] => Array ( ) [className:Parse\ParseObject:private] => _User [objectId:Parse\ParseObject:private] => xmoc179ICy [createdAt:Parse\ParseObject:private] => [updatedAt:Parse\ParseObject:private] => [hasBeenFetched:Parse\ParseObject:private] => ) Parse\ParseUser Object ( [_sessionToken:protected] => [serverData:protected] => Array ( ) [operationSet:protected] => Array ( ) [estimatedData:Parse\ParseObject:private] => Array ( ) [dataAvailability:Parse\ParseObject:private] => Array ( ) [className:Parse\ParseObject:private] => _User [objectId:Parse\ParseObject:private] => xmoc179ICy [createdAt:Parse\ParseObject:private] => [updatedAt:Parse\ParseObject:private] => [hasBeenFetched:Parse\ParseObject:private] => )

Update - working code :

    $query = new ParseQuery("Animation");
    $query->includeKey("createdBy");
    $query->descending("createdAt");
    $query->limit(2);
    $results = $query->find();


    for ($i = 0; $i < count($results); $i++) { 

      $object = $results[$i];
      $user = $object->get("createdBy");
      $username = $user->get("username");


      echo($username);
}

What does the $userID look like if you run print_r or var_dump? Maybe you just need to fetch what's inside like. $userID['name'] or $userID->name — Karl

By default queries won't fetch nested/related objects, so you basically get a pointer.

Try looking at ParseQuery::includeKey().
