I can only swear this to the entire list:
Before I come here for help, each time, I echo and var_dump and print_r
until, yes, I need a doctor.
So by the time I come here, it's not laziness or lack of looking in the
manual, it's head-swirling confusion infused with incompetence and a
complete lack of programming experience at any time before April of this
year which leads me to come back again and again with relatively foolish
questions.
My problem before, for example: In my error check function, I placed the
include file (to return to the form) *within* the foreach loop, and then
I wondered why it only ran through once.
D'oh.
