1 - I want to make a page that allow user to enter information that will be sent to the database. At the same time, the user must sign up a user ID and password for security purposes, in the same page (just like signing up an email account).
- How to do this?
- Also, how to check that the user ID is still availabe (not being
taken by other existing user)
2 - Next time when the user want to view the information he or she had entered, he/she must enter his/her userID and password to go to the page that will retrieve the information from the database. That means the user is only permitted to view his/her own information, and not other user's one.
- Again, how to do this?
