User Registration 1.5beta1 - one feed for registering and editing profile

Hello,

I was wondering if it's possible to use the same User Registration feed form for both registering and editing details of already registered users.

I've got:
1. A Register form.
2. A User Registration feed with the action "Create User" that uses the Register form.
3. A Custom Registration Page is Enabled & that page has got Gravity Form shortcode to Registe form.

Now, after a registration a user is redirected to an account page. Is there a way to use the same user registration feed, but make it pre-populated with user data and make it of action "Update User". Can this be done via hooks?

If not what's the best way to do it?

Many thanks, Dasha

Chris,
I did exactly what you suggested.

I have a user registration form that requires:
username
email
password

I then send user to their profile page so they can update their information. On the page I have a GF that is mapped to an 'Update User' GF. That lists this info:

username
email
password
first name
last name
phone
city
birthdate

As a test I signed up, logged in, and edited my info - I added my full name, phone #, city, and bday.

Then I logged out.

When I logged back in, the birthdate and username fields are blank.

As this is just a test, I only added a few fields but I do plan to add about 5 more fields.

My question is, how do I get my ALL of my GF 'User Update' fields to display the data?

Does my solution lie in this thread? http://justintadlock.com/archives/2009/09/10/adding-and-using-custom-user-profile-fields

Must I user Tadlock's solution to save all the user info into my database?

Thanks! Ben
