Class Phalcon\Mvc\Model\Transaction\Manager

implements Phalcon\Mvc\Model\Transaction\ManagerInterface, Phalcon\DI\InjectionAwareInterface

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 trasaction produces a unique connection that is passed to every object part of the transaction.

<?php

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();
}
