Before reading this guide, you should have read and completed part 2 of this series. Specifically, you should have the mymarket database up and running, and have all the user management functions running. Your PHP4 sessions should also be working.

If you have not already done so, please read Part 2 of this guide at:

• Building an E-Commerce Site Part 2: Managing Users with Sessions

Also, if you want to follow this guide and get a working site, you must use PHP4. The final release of PHP4 is out now, so you should probably upgrade to that if you are still using any pre-release version.
