I am trying to create a form for a MySQL database similar to a spreadsheet.
The idea is to display a list of records, with the last line of the list
being an input form. When the user enters data in the form and hits the
submit button, the data is entered and the form is reloaded with the new
data displayed and another input form becomes the last line.

Example ---

Before entering new data

Record 1
Record 2
Record 3
Input form Submit button


After entering new data

Record 1
Record 2
Record 3
Record 4
Input form Submit button

It seems is what I think the approach should be:

1. Display all current records - the last line is an input form
2. User adds data to the form and hits the Submit button
3. The form action calls the same script
4. The new data is entered into the database
5. Back to step one

Does this make sense or is there a better way? How do I structure the
queries to accomplish this?

Thanks in advance.
