Yeah, it's also great to use if statements when you're using the POST method in a form and you have required fields. Here's an example. <form action=login.php method=POST>Email: <input type=text name=email><br>Password: <input type=password name=pass><br><br><input type=submit value=Login!> Now we make sure our required fields have been filled. <?php session_start(); if (!$email) { print "You didn't enter your email into the form! Please go back and do so."; exit; } elseif (!$pass) { print "You didn't enter a password! Please go back and do so."; } else { session_register($email); session_register($pass); } ?> ---- Manual Page -- http://www.php.net/manual/en/control-structures.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39190 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39190&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39190&report=yes Search -- http://master.php.net/manage/user-notes.php
