    To validate before submitting the form, you pretty much have to use javascript, if the form is valid you can have JS submit it too. There's tons of JS validation scripts out there, pretty much take your pick, or write your own. The !isset code doesn't really mean anything, the form field can be blank but still set. It only has to be an input with a name to be set.

    Also you can simplify your code by looping over $_POST.

    You can validate after submission and return to the form page with the fields refilled and any notices echoed, but that takes different code.

    You need to use JS for client side validation. Of course, you'll still need to validate server side since client side validation is unreliable. Look into ajax if you'd like to mix the JS and the PHP together, but note that you will consume substantially more bandwidth in doing so (and you'll still need to validate on the server side).
    PHP Code:
    header('HTTP/1.1 420 Enhance Your Calm'); 
    Been gone for a few months, and haven't programmed in that long of a time. Meh, I'll wing it ;)
