Parse.com - Parse PHP SDK - How can I query data by pointer field?

Question

I have two objects Puzzle and the PuzzleAnswer. In PuzzleAnswer I have field "puzzle Pointer<Puzzle>" which equal to field "objectId" in Puzzle. How can I query answers by pointer field "puzzle"? This code work well with all field except "puzzle".

$query = new ParseQuery("PuzzleAnswer");
$query->equalTo("Puzzle", "kBT3M6YpvY");
$result = $query->find();

print "<pre>";
var_dump($result);
exit;

result:

array(0) {

}

Thank.

i haven't used Parse but, as i checked documentation now, yout equalTo method receives ParseObject so can you try this; $puzzle = new OarseObject('kBT3M6YpvY'); $query->equalTo('Puzzle', $puzzle); — engvrdr

Thanks for your reply. I checked out, but it didn't help. The fact that it works for other fields, the problem is only with the field puzzle which is "Pointer" — Alexander Bogdan

You are searching for a pointer field with a string. It requires you to search with a Parse Object.

Either create a query for the pointer fields object:

$puzzle = new ParseQuery('Puzzle');

$puzzle->equalTo('objectId', $puzzleId);

$first = $puzzle->first();

Or by bypassing this and passing it an object we create

$query->equalTo("Puzzle", ['__type' => "Pointer", 'className'=> "Puzzle", 'objectId' => $id]);

$result = $query->find();
