Answer 1

No new record added in the table?
Check return value from mysqli_stmt_execute maybe?

Initialize the statement using mysqli_stmt_init() first, then prepare the statement using mysqli_stmt_prepare()

Answer 2

In file register.php;
Values for variable $name, $email and $password is not yet initialized when they are bound as arguments for the statement (at line 8). $name, $email, and $password are initialized at line 9, 10 and 11, respectively.
