The problem is, that I have multiple fields and what I am trying to do is
check each field to make sure I get the data that I need and not some crap,
like letters in a number field or a <script> tag in a field. Things of this
sort. The foreach loop wont work for me in this instance because Im
checking for proper input.
I can write multiple elseif statements to check each field but alas, this is
not optimal. I may go ahead and write this to get it done and then go back
and put it to the write board....
