Class Phalcon\Mvc\Model\Transaction\Manager

A transaction acts on a single database connection. If you have multiple class-specific databases, the transaction will not protect interaction among them.

This class manages the objects that compose a transaction. A transaction produces a unique connection that is passed to every object part of the transaction.

try {
   use Phalcon\Mvc\Model\Transaction\Manager as TransactionManager;

   $transactionManager = new TransactionManager();

   $transaction = $transactionManager->get();

   $robot = new Robots();

   $robot->setTransaction($transaction);

   $robot->name       = "WALL·E";
   $robot->created_at = date("Y-m-d");

   if ($robot->save() === false){
       $transaction->rollback("Can't save robot");
   }

   $robotPart = new RobotParts();

   $robotPart->setTransaction($transaction);

   $robotPart->type = "head";

   if ($robotPart->save() === false) {
       $transaction->rollback("Can't save robot part");
   }

   $transaction->commit();
} catch (Phalcon\Mvc\Model\Transaction\Failed $e) {
   echo "Failed, reason: ", $e->getMessage();
}
