it would be nice if the SecureData-function could be extended by variable-taypes like in the Wordpress database-class (https://codex.wordpress.org/Class_Reference/wpdb#INSERT_rows).
This can increase the database-security much more and ensure that no values enter the db that shouldn't.
i think that types like string, integer, float, boolean (true/false || 1/0) and datetime date timestamp would be nice.
