Package Tracking Plus 2.0
This contribution allows osCommerce store owners to provide real-time UPS, USPS, Fedex, Fedex Freight, and DHL package tracking to their customers. Store owners just enter the tracking number into text boxes on the orders page inside admin. This should be done when updating the order status to "Shipped" - afterwards, the customer will receive an email telling them the order has been updated. The subject of emails will contain the order number and status while the text will include a personalized greeting. Comment text will not be included unless comments are added. Included in the email is a link which takes them to their account page on your website as well as the individual tracking number(s) with their appropriate shipper indicated (ie. USPS, UPS, Fedex, Fedex Freight, and/or DHL).
You can have multiple shippers (ie. tracking number) for each order in any combination. (ie. you can have a package tracking for both USPS and Fedex for the same order). On the order details page, the customer will find a clickable link and button to track their package. The link will open in a new window, so the customer never leaves your website. Additionally, you will find the order emails to be substantially warmer and more professional.
