Once you have determined a particular field is invalid, all you need to do is change the style of the control using something like this...
CODE
<input type="text" name="nickname" <?php if (isset($user_bg) && ($user_bg == "red")) { echo "style=\"border: #FF0000 solid 1px;\""; } ?>>
What this is doing is using php inside an input element where it checks to see if the $user_bg is first set and that it is set to "red" (meaning that you had determined it was an error). If these conditions are true, echo a style tag which sets the border to a 1px solid red line.
I hope that makes some sense. Remember you can put php code output anywhere, even in the middle of an input tag.
Good luck!
