$dbuser = ultra ;
$dbpass = reviled1 ;
$dbname = user ;

$connection = mysql_connect($host,$dbuser,$dbpass);
$db = mysql_select_db($dbname,$connection);

//grab data from form
$name = $_POST[username];
$pass = $_POST[password];
$pass_conf = $POST[pass_conf];
$email = $_POST;
$ip = $_POST[ip];

//if else
if($name == false || $pass == false || $pass_conf == false || $email == false)(
echo "Please fill in all the required fields."
);
if($pass != $pass_conf){
echo "Passwords do not match.";
)else (
$connection = mysql_connect($host,$dbuser,$dbpass);
$db = mysql_select_db($dbname,$connection);
$sql = "INSERT INTO user (username,password,email,ip) VALUES ($name, $pass, $email, $ip)
$result = mysql_query($sql);
echo "Thank you for your registration to artsimulacrum.com";
