Note The values of ADMIN_EMAIL and SUPPLIER_EMAIL will actually be used to send emails to. In other words, these must be existing, real email addresses that you can verify. You can leave CUSTOMER_SERVICE_EMAIL and ORDER_PROCESSOR_EMAIL as they are because they re used in the FROM field of the emails, and they don t need to be valid email addresses.

Note If you haven t configured your SMTP server correctly, you ll get an error when the code tries to send
the email. If that happens, check Appendix A for installation and configuration instructions.
14. Check your inbox for a new email that should read Test mail from PsDummy. 15. Examine the audit table in the database to see the new entries (see Figure 13-5).

How It Works: The Skeleton of the Order-Processing Functionality
Entries will be added by OrderProcessor and by individual pipeline stages to indicate successes and failures. These entries can then be examined to see what has happened to an order, which is an important function when it comes to error checking. The message number column is interesting because it allows you to associate specific messages with an identifying number. You can have another database table that matches these message numbers with descriptions, although this isn t really necessary because the scheme used for numbering (as you ll see later in the chapter) is quite descriptive. In addition, you have the message column, which already provides human-readable information. For demonstration purposes, we set the administrator and supplier email addresses to fictive email address, which should also be the address of the customer used to generate test orders. You should do this to ensure everything is working properly before sending mail to the outside world. Let s now look at the OrderProcessor class. The main body of the OrderProcessor class is the Process() method, which is now called from function.load_admin_order_details.php to process an order. public function Process() { // Configure processor $this->mContinueNow = true; Next you used the CreateAudit() method to add an audit entry indicating that OrderProcessor has started: // Log start of execution $this->CreateAudit('Order Processor started.', 10000);
