$unset not properly work on multiple field?

[vaporizel]

I want to remove all these field below from certain record :

• membership_active_time (integer)
• membership_renewal_time (date)
• membership_start_date (date)
• membership_type (text)
• metadata (object of field)
• vendor_payment (text)

but the problem is only remove 2 field : membership_renewal_time and metadata, this is my code :

$this->result = $this->user_collection->updateOne(
	['owner_user_code' => $this->input_owner_user_code],
	['$unset' => 
		[
			'membership_active_time' => true,
			'membership_renewal_time' => true,
			'membership_start_date' => true,
			'membership_type' => true,
			'metadata' => true,
			'vendor_payment' => true,
		],
	]
);

im also tried with => false, => "", => '', but still only deletes certain field like i said above

The syntax you have looks correct. Note that the value of the fields in the $unset document are not relevant. Only the keys are used to discern the field names.

<?php

require __DIR__ . '/../vendor/autoload.php';

use MongoDB\BSON\UTCDateTime;
use MongoDB\Client;

$client = new Client('mongodb://localhost:27070/?replicaSet=rs0');

$coll = $client->selectCollection('test', 'coll');
$coll->drop();
$coll->insertOne([
    'owner_user_code' => 1,
    'membership_active_time' => 100,
    'membership_renewal_time' => new UTCDateTime(),
    'membership_start_date' => new UTCDateTime(),
    'membership_type' => 'foo',
    'metadata' => ['x' => 1],
    'vendor_payment' => 'bar',
]);

var_dump($coll->findOne());

$updateResult = $coll->updateOne(
    ['owner_user_code' => 1],
    ['$unset' => [
        'membership_active_time' => true,
        'membership_renewal_time' => true,
        'membership_start_date' => true,
        'membership_type' => true,
        'metadata' => true,
        'vendor_payment' => true,
    ]],
);

printf(
    "\nupdateOne matched %d and modified %d\n\n",
    $updateResult->getMatchedCount(),
    $updateResult->getModifiedCount(),
);

var_dump($coll->findOne());

Output:

object(MongoDB\Model\BSONDocument)#18 (1) {
  ["storage":"ArrayObject":private]=>
  array(8) {
    ["_id"]=>
    object(MongoDB\BSON\ObjectId)#23 (1) {
      ["oid"]=>
      string(24) "661fcfc37a3fa8243500cdb2"
    }
    ["owner_user_code"]=>
    int(1)
    ["membership_active_time"]=>
    int(100)
    ["membership_renewal_time"]=>
    object(MongoDB\BSON\UTCDateTime)#22 (1) {
      ["milliseconds"]=>
      string(13) "1713360835821"
    }
    ["membership_start_date"]=>
    object(MongoDB\BSON\UTCDateTime)#17 (1) {
      ["milliseconds"]=>
      string(13) "1713360835821"
    }
    ["membership_type"]=>
    string(3) "foo"
    ["metadata"]=>
    object(MongoDB\Model\BSONDocument)#15 (1) {
      ["storage":"ArrayObject":private]=>
      array(1) {
        ["x"]=>
        int(1)
      }
    }
    ["vendor_payment"]=>
    string(3) "bar"
  }
}

updateOne matched 1 and modified 1

object(MongoDB\Model\BSONDocument)#13 (1) {
  ["storage":"ArrayObject":private]=>
  array(2) {
    ["_id"]=>
    object(MongoDB\BSON\ObjectId)#19 (1) {
      ["oid"]=>
      string(24) "661fcfc37a3fa8243500cdb2"
    }
    ["owner_user_code"]=>
    int(1)
  }
}

Closing as it works as expected.
