PhpOrient - begin()

This method begins a transaction.

Beginning Transactions

Once you have the transaction interface initialized through the getTransactionStatement() client interface method, using this method you can initialize a transaction statement, using the other methods to attach and commit or revert the changes as need.

Syntax

$tx = $tx->begin()

Example

Consider the use-case of a web application in which you frequently update records as part of a transaction. You might use a function similar to this to handle both the transaction and update operations together.

// INITIALIZE TRANSACTION INTERFACE
$tx = $client->getTransactionStatement();

// UPDATE RECORD
function updateRecord($class, $data, $rid){

    // Log Operation
    echo "Updating Record";

    // Fetch Globals
    global $client;
    global $tx;

    // Begin Trasnaction
    $tx = $tx->begin();

    // Build Updated Record
    $record = new Record();
    $record->setOClass($class);
    $record->setOData($data);
    $record->setRid($rid);

    // Update Database
    $update = $client->recordUpdate($record);

    // Attach Operation to Transaction
    $tx->attach($update);

    // Commit Changes
    return $tx->commit();
}
