I have a big form. To facilitate user i have added Submit button after every 10 rows. For some reason form is not submitting values of one text field (pqty[]) after 3 submit buttons. Form is not submitting values of row 31 and onward. What can be problem? Please suggest.
4k lines of code seems a bit ridiculous, so that could be your first problem. But no just post the relevant code.
Pretty much without seeing the code and/or a live copy of what's going on -- and, well... you've tread into 'we can't help you' territory. Is it a classic form, are you generating these elements client-side or server-side? Are you knee deep in scripttard BS so that it has no graceful degradation and is loading megabytes of scripting to do 5k of markup's job? But yeah, 4K LINES of code is shoot yourself in the head time if that's JUST the code that makes the form and handle's it's processing.
