Bug #74848 [Opn->Nab]: the parameter fields does not work

Edit report at https://bugs.php.net/bug.php?id=74848&edit=1 ID: 74848 Updated by: cmb@php.net Reported by: blackpanther dot online at gmx dot de Summary: the parameter fields does not work -Status: Open +Status: Not a bug Type: Bug Package: mongodb PHP Version: 7.1.6 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: It seems you've mixed up Mongo and MongoDB; the documentation of the former is not necessarily valid for the latter, and in this case this actually looks like an issue with the Mongo PHP library, so please report there[1], if it still persists. [1] <https://github.com/mongodb/mongo-php-library/issues> Previous Comments: ------------------------------------------------------------------------ [2017-07-03 14:09:15] blackpanther dot online at gmx dot de Description: ------------ --- From manual page: http://www.php.net/mongocollection.find --- If you pass the second parameter fields, you should receive only the fields given, but actually you receive all. You can pass ["field_a" => true] and get all fields. The same then you pass ["field_a" => false]. So it's not working. (If you check the mongodb's find method directly on the database without php by collection.find({},{"field_a":1}) it works properly) Test script: --------------- require '../vendor/autoload.php'; $mongodb = new MongoDB\Client("mongodb://xx:xx@localhost:27017/test"); // needs an existing mongodb server $collection = $mongodb->test->phpfind; // needs an existing database // create a new record $collection->insertOne(['field_a' => 'A', 'field_b' => 'B']); // should return a entry with only _id and field_a as fields print_r($collection->findOne([], ['field_a' => true])); // should return a entry with only _id and field_b as fields print_r($collection->findOne([], ['field_a' => false])); Expected result: ---------------- MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_a] => A ) ) MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_b] => B ) ) Actual result: -------------- MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_a] => A [field_b] => B ) ) MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_a] => A [field_b] => B ) ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74848&edit=1
