更新时MongoDB PHP驱动程序错误

Question

I have recently upgraded to PHP7 and to the MongoDB driver from PHP 5.5 and the old Mongo driver. I have changed all the functions from update() to updateOne() and updateMany(), as well as the remove() functions.

However, the first time my application attempts to perform an updateOne error, I am getting an error. The DB connection code looks like this. Please note that I have added an updateOne function in the constructor as a test once I saw I'm receiving errors :

if (!extension_loaded('mongodb')) die("MongoDB is not installed!");
        try {
            $this->connection = new MongoDB\Client('mongodb://'.$auth.self::HOST.':'.self::PORT.$authDb);
            $this->database = $this->connection->selectDatabase(self::DBNAME);

            # Test function, added due to errors

            $this->connection->WIOC->settings->updateOne(array('_id' => 'xxx'), array('$set' => array('test' => 'yes')));
        } catch (MongoConnectionException $e) {
            throw $e;
        }

The error I'm getting is this:

: Uncaught Error: Call to undefined method MongoDB\\Driver\\BulkWrite::updateOne() in /Users/Idan/Sites/MyApp/include/vendor/mongodb/mongodb/src/Operation/Update.php:140 Stack trace: 0 /Users/Idan/Sites/MyApp/include/vendor/mongodb/mongodb/src/Operation/UpdateOne.php(77): MongoDB\\Operation\\Update->execute(Object(MongoDB\\Driver\\Server)) 1 /Users/Idan/Sites/MyApp/include/vendor/mongodb/mongodb/src/Collection.php(828): MongoDB\\Operation\\UpdateOne->execute(Object(MongoDB\\Driver\\Server)) 2 /Users/Idan/Sites/MyApp/include/mongoConnect.php(30): MongoDB\\Collection->updateOne(Array, Array) 3 /Users/Idan/Sites/MyApp/include/mongoConnect.php(40): DBConnection->__construct() 4 /Users/Idan/Sites/MyApp/include/framework.php(6): DBConnection::instantiate() 5 /Users/Idan/Sites/MyApp/index.php(3): require('/Users/Idan/Sit...') 6 {main} thrown in on line

var_dump of $this->connection->MyApp->settings shows a MongoDB\\Collection, so I assume I'm using the appropriate newer driver. Even stranger, here is the list of methods for the object:

Array
(
    [0] => __construct
    [1] => __debugInfo
    [2] => __toString
    [3] => aggregate
    [4] => bulkWrite
    [5] => count
    [6] => createIndex
    [7] => createIndexes
    [8] => deleteMany
    [9] => deleteOne
    [10] => distinct
    [11] => drop
    [12] => dropIndex
    [13] => dropIndexes
    [14] => find
    [15] => findOne
    [16] => findOneAndDelete
    [17] => findOneAndReplace
    [18] => findOneAndUpdate
    [19] => getCollectionName
    [20] => getDatabaseName
    [21] => getManager
    [22] => getNamespace
    [23] => insertMany
    [24] => insertOne
    [25] => listIndexes
    [26] => replaceOne
    [27] => updateMany
    [28] => updateOne
    [29] => withOptions
)

Any idea what is wrong? thanks!

The code you have provided makes use of legacy MongoDB driver and hence is not compatible with the new one .

Provided you have actually installed the newest driver, the proper way to perform any kind of updates (update/insert/delete) is achieved through the usage of MongoDB\\Driver\\Manager::executeBulkWrite method.

The complete sample code is provided below:

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->update([ '_id' => 'xxx' ], [ '$set' => [ 'test' => 'yes' ]]);
$manager->executeBulkWrite('DB.Collection', $bulk);
