I have been asked to help a person who has written a professional book. She would like to sell an electronic version of the book through a shopping cart. Once the user has purchased the e-book, then they would somehow register for a login/password which would grant them access to the e-book. This e-book is simply several html files having chapters of the book. The registered user would have access to read these pages, but would not be able to copy/print the pages. The user could come back often to read the book from these web pages, after entering their registered login/password.
My expertise is on the ASP.NET/C# side, but the web host servers only have PHP / MySQL, which is the owner's preference. The owner also likes using DreamWeaver, and I notice there is a Login PHP extension that is available, but other solutions may be better. Esentially, we need some kind of shopping cart and the ability to register users to access the web pages of the e-book. What would be a good way to do this?
