Re: preg_match array question

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.... -dan ----- Original Message ----- From: "Ralph" <ralph@nqionline.com> To: "'Daniel J.
