Sorry I'm not sure if I understood the question, I'll start from the beginning, and hopefully this will lead in the correct directionFirst expiry
The way this works with passwords, is that before the book expires, any password protected pages are protected from viewing. Any unpassworded pages can be seen. When the book expires, ALL pages become password protected. When the password is entered (before or after expiry), any password protected pages become available, including those that might have "become" password protected thanks to expiry
Next passwords
The idea here is to have a bunch of passwords. The user needs a particular one to read the book on his PC. So the normal system with password would be (a) user downloads a trial version, reads part of the book (or a limited time until book expires), (b) user pays, (c) user gets password to read all the pages. The difficult part is to give the user the correct password.
The trick is to either make 1 sales/thank you page for each password OR use a script which distributes passwords automatically. The first method of the trick requires no programming skills but much cutting and pasting. The clickbank method to do this is documented atwww.ebookapprentice.com/sell/cbpassword . The 2nd version of the trick requires a script but no cutting and pasting. See scripts section ofwww.ebookcode.comfor how-to get started. There are also third party products, some of which have probably been discussed on this forum, to do this.
For both we versions of the trick we have instructions for clickbank only. You may be able to adapt these instructions for paypal.
Finally, there are other ways to achieve similar goals, or in some cases more advanced goals - including a number of compatible third party products, again some of which have been discussed on this forum. Look for old threads discussing ebookcompiler aps and goldpanner.ca . If you are struggling to adapt the clickbank instructions we provide, these may prove particularly helpful.
