As ... "spinner" bahseder:

The spinner is a hidden field used for a few things: it hashes together a number of values that prevent tampering and replays, and is used to obscure field names. The spinner is an MD5 hash of:

* The timestamp,
* The client's IP address,
* The entry id of the blog entry being commented on, and
* A secret.

The field names on the form are all randomized. They are hashes of the real field name, the spinner, and a secret. The spinner gets a fixed field name, but all other fields on the form, including the submission buttons, use hashed field names.

Does anyone have a code sample of how to implement this on a php page containing a form and the associated php form submission script?

AJAX, sadece PHP kullanmak istemiyorum.
