How is data from the signup form entered into mysql?
I want to manually add fields to the registration form. I know Wordpress has a feature for that, but I want to add the data to regular custom wp_users table fields, not hidden as relational data in the wp_usermeta table or wherever the hell it ends up.
I also need certain custom fields in wp_users to be able to import member data from another system.
How can I add fields for custom fields in wp_users to the form by simply adding the lines to the code and editing the query?
