need some help with costomizing a guestbook. I'm a newbie and some of the code I don't understand pretty well.
I wanted to make the name input a required field. Also there is a piece of code that enters "anonymous" into the name field if u don't put a name, also if it's possible to get rid of that. and I don't know if it's too much to make the email a valid email if insert but not a required field.
<?php

$real_name = addslashes($_POST['name']);
$email = addslashes($_POST['email']);
$homepage = addslashes($_POST['homepage']);
$message = addslashes($_POST['message']);
$sql = "insert into $guest_tblname (nickname, real_name, email, homepage, message, date_added) values ('$nickname', '$real_name', '$email', '$homepage', '$message', NOW())";
if ($add_message = mysql_query($sql)) {
