Relatively simple form - nothing fancy -
Post goes thru exactly as expected with I.E. v11 and Edge .
However - with Chrome and Firefox - ONLY two hidden fields come thru, the rest of the post results are null/empty.
Convert to GET and I get the same results.
This is a straightforward HTML form using a submit button, and the action is a straightforward php script that collects the field values and inserts them into a MySQL database. Old school stuff.
I'm bewildered at this point.
