Class Phalcon\Mvc\Model\Transaction

implements Phalcon\Mvc\Model\TransactionInterface

Transactions are protective blocks where SQL statements are only permanent if they can all succeed as one atomic action. Phalcon\Transaction is intended to be used with Phalcon_Model_Base. Phalcon Transactions should be created using Phalcon\Transaction\Manager.

<?php

try {

  $manager = new Phalcon\Mvc\Model\Transaction\Manager();

  $transaction = $manager->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();
}
