I'm working on a web interface to do some rather simple DB maintenance. Low volume SELECTs & UPDATEs mostly.

The form will have a handful of simple records displayed from a few tables. For purposes of discussion, let's say we have 5 records from each of two tables. Also, let's say that I'm displaying the PKey read-only, and I have form inputs for the other fields. Each set of records is followed by a new blank row, in case the user wants to INSERT a new record.

Which what mechanism would you recommend I keep track of what data has been offered and returned? (Specifically, so I can build my SQL.) Right now, I have generated fieldnames that hold the table and the rowID, but this is grossly, horribly insecure, and I know that. TMTOWTDI, and this is a *poor* way.

Secondly and less importantly, can you recommend a mechanism that will help me know when my data is 'dirty'? That way, I can minimize my transactions to those that are neccessary. I could roll my own with standard comparison, but this is one of those cases where I feel I'm about to poorly re-implement the proverbial wheel.

Thank you Monks.
