how to retrieve data

[intan]

I'm doing a memo system.Part of the system is something like this.. Suppose,..when the user click preview button..it will display all the information that he/she wrote in memo page..but when i click preview button,the same data appear (which is the first record stored in database) eventhough i wrote a new memo.Can someone help me and give me some example how to retrieve the data based on what the user have wrote..

Thanks..

I think what you mean is that you have a record already stored in the database which you can view at anytime by clicking a button? And you can also edit this record but you can also click preview to view the edited record without changing the saved record - is this correct?

If so, you are probably better off storing the 'edited' text in a session variable and when you are happy with the text, saving it will update the record in the database.

That's if my assumption is correct of course!
