Table - Form - submit only changed data - how ?
Table - Form - submit only changed data - how ?
I'd like to use a table to gather/submit form data
I'd also like to allow the user to submit the form, then come back to it to revise it / add to it
To save processing, if a revised/edited table is submitted, I'd like the form to submit only the new/changed data
Thus, is there a way to have the form 'remember' what was already submitted, to then send only the new/changed stuff, and to build the fully updated file on the server?
EXAMPLE
1. A form of 4000 rows is submitted, customer comes back to form, adds two new rows, then submit button is clicked and only the two new rows are submitted.
2. The same form above is pulled up again, now has 4002 rows, a few of the first rows are edited and also 3 new rows are added. This time, the edited top few rows plus the 3 new rows are submitted, even though the full 4005 row table is in the user's browser.
The idea is to save the server juice if at all possible while still giving the user a "complete" experience.
Thanks :-)
