Get data submitted from Login/Registration page in Wordpress

Question

I am looking for any hook using which I can get the data (and perform some calculation) submitted from default Login and Registration forms of Wordpress. I am searching for such hooks through internet but not able to find any.

Answer 1

So, to recap:

Action hooks wp_login and register_post can be used to intercepts the data send by the login and registration form; although that is only for the “standard” data those forms send.

If you have enhanced these forms with custom fields, you can access their data directly in these hooks using $_POST . Although that might not seem to be the cleanest way, it is an approach that is described in the WP docs , so maybe there is no “better” way explicitly provided to do things like this.
