Re: Posted form values - checkbox problem

cow1.php <form method="post" action="cow2.php"> <input type="checkbox" name="cow"> <input type="submit"> </form> cow2.php <? echo phpinfo();?> If you run cow1.php, then have it submit to cow2, there will be no HTTP_POST_VARS["cow"] unless the "cow" is checked. I've no way of knowing if 'cow' was the name of a checkbox on the form that wasn't checked, or just not a checkbox at all. Runing PHP4.03pl1 if that makes a difference.
