Well having a form with LOTS of fields, it might be advisable to have
the fields send an array straigt away
have the name of your fields something like <.. name="feedback[name]"
..> and just use global $feedback and the whole array is at your
disposition.
This doens't change the way global is treated in PHP but might help
you in your setup. having these in an array will also greatly make
sessions easier, if you have to follow all these fields on multiple
pages.
