Should work, but I'd recommend using the trim function around your post variables in case they hit the space bar in the box or something else got screwy.

And it goes at the top of whatever page you do your processing on. Normally you'd submit a form to the same page and if the if statement fails, you display the error message and show the form again. If you're going to go as far as highlighting the ones they missed, you're going to have to set a bunch of flags to change the look of those fields in the form.
