No problem, thx for the book and available example codes. Found another one In the page.php file for recording the history the example files state: $q = "INSERT INTO history (user_id, type, page_id) VALUES ({$_SESSION['user_id']}, 'page', $page_id)"; $r = mysqli_query($dbc, $q); the query should state item_id instead of page_id, in the book this is written correct. In the favorites.php example files it states: // Include the header file: $page_title = 'Your Favorite Pages'; include('./includes/header.html'); echo '<h3>Your Favorite Pages</h3>'; // Require the database connection: require(MYSQL); the require(MYSQL); should be placed before the header.html part because the header.html file makes a MySQL query for categories and the require mysql file is not in that file. page 394 updating register.php and page 395 updating add_page.php with prepared statement mysqli_stmt_close(); should be mysqli_stmt_close($stmt);

Hi, I believe I found 2 mistakes in the (downloadable example codes) The first is in the MySQL file in the table orders, the MySQL file states: CREATE TABLE `orders` ( `id` INT UNSIGNED NOT NULL AUTO_INCREMENT, `users_id` INT UNSIGNED NOT NULL, `transaction_id` VARCHAR(45) NOT NULL, `payment_status` VARCHAR(45) NOT NULL, `payment_amount` INT UNSIGNED NOT NULL, `date_created` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (`id`), INDEX `date_created` (`date_created` ASC), INDEX `transaction_id` (`transaction_id` ASC), CONSTRAINT `fk_orders_users1` FOREIGN KEY (`id`) REFERENCES `users` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION ) ENGINE = InnoDB DEFAULT CHARSET=utf8; The constraint states the foreign key is 'id' and references to table 'users' id, however the id in table orders is auto incremented. Should it not be FOREIGN KEY (users_id) with REFERENCES `users` (`id`)?? The second is on page 173 (Chapter Creating the IPN script) The query states: $q = "INSERT INTO orders (user_id, transaction_id, payment_status, payment_amount) VALUES ($uid, '$txn_id', '$status', $amount)"; However I believe user_id should be users_id I am probably be wrong because even with these changes I just cant get the IPN script to work, i found a alternative script that does work though.
