  Hello Kalpesh,

  Thank you so much for you generosity in posting code. I am a contractor, enhancing an existing website. I am pretty new to Magento. Which Observer.php do I put the code into listed aabove.. there are quite a few.

  I have one direct question and one indirect question. I am extending the website allowing the site owners to become an affiliate and using a service to deliver products electronically. If, during an oredr (which may contain other products), the request to the service fails (database problem on their end, server error, or just site down for whatever reason, I want to roll back the order. Can you give me an idea of where I need to put the logic? Do you know of any extensions that might help with this?

  Thanks
  Mark

    Hi Mark, you can place it in your custom module observer file. You can check for custom local modules at app/code/local/ and probably put the code in one of the module you or other developer created for extending/adding some functionality to the website.

    If something goes wrong during placing an order, Magento will not commit the transaction at all. Magento roll-backs the entire transaction if there is error in the order process. If this is something you want to do it custom, you can do something like this:

    1 2 3 4 5 6 7 8

    $connection = Mage::getSingleton('core/resource')->getConnection('core_write'); try { $connection->beginTransaction(); // Do all the database write operations like saving in different tables $connection->commit(); } catch (Exception $e) { $connection->rollback(); }
