Answer 1

You're at risk of MySQL injections. Never insert data directly to a database without some sort of projection first. It's a major security risk. Also use mysqli_real_escape_string instead, and note that your $_POST[webSite] is unprotected.

Also, your error means that your database details are not correct.
