Trying to integrate form.php file with phplist.hosted database.

<?php
// CONFIGURATION
$host = "host"; // DAtabase address
$username = "username"; // Databse username
$password = "password"; // Database password
$database = "dbname"; // Database name

$connect = @mysql_connect($host, $username, $password) or die (@mysql_error());
$selectdb = @mysql_select_db($database, $connect) or die (@mysql_error());


//  DATABSE INSERT
if(isset($_POST))
{
    $email = $_POST['email'];

    if (empty($email)) {
        $status = false;
    }else{
        @mysql_query("INSERT INTO newsletter SET email='$email'");  // dont forget to change table name if you'll use another table name.
        $status = true;
    }

    echo $status;
}
