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); } ?>
