$password = isset($_POST['password']) ? $database->escape($_POST['password']) : '';
//Okay, now we've figured out if they've set the url, let's add it to the DB

My MYSQL structure is: id, url, views, keys

Answer 1

key is a MySQL reserved keyword, you need to quote it with backticks if you want to use it as a field name.

INSERT INTO urls (url,pass,`key`)...
