<form action="" method="post">
name <input type="text" name="name"><br/>
email <input type="text" name="email"><br/>
<input type="submit" name="sb" id="sb" value="go">
</form>
<?php

if(isset($_POST['sb'])) {
extract($_POST);

if(empty($name) || empty($email)) die("email and name emtpy");

print "Name is $name and email is $email now!";
}
?>
