How to enforce users to input user account's fields after user registeration? I'm useing D7.

What I want to do is...

Step1: Let users register only by inputting their email address &amp; password on  user registration form (http://www.my_website.com/user/register)

Step2: Redirect them to user account edit page (http://www.my_website.com/user/user id/edit) after their registration. And then, enforce them to input the rest of fields such as [first_name] &amp; [hobby] on the edit page.

The 'step1' was able to be done by using  'Email Registration' &amp; 'User registration password' module. And I think I can redirect users to the edit page. But I don't know how to enforce them to complete the rest of fields in edit page. 

I want to do this without using Profile2 module. Does anybody have idea to do that?

I'm really sorry if this is an entry-level question to you. But I'm very new to Drupal and I have been struggling with this for a week, but I couldn't find the way. Please somebody help me!

Thank you!
Try using Rules. You could add a new field into the users' accounts that is Completed Profile Fields and it could be a single boolean or possabily a multi-value field.

Then your rule could check:


If login, or page load -- has user completed profile fields? If yes, continue to any page -- else show a profile form page (not necessarily their account page).
I'm not sure it would be easy to do this globally, or test the profiles have been filled prior to going to a /node/add page for instance.
After filling in the profile values the Rule could update the user account field completed profile fields to True.


If you don't want users to see this completed profile fields field -- you can install and use Field Permissions.

EDIT

If you dont want the user to see this special completed profile fields but still want the rule to update the value you may need to set the uid of the user updating this field. I do this usually by creating a fake user for the system called like mysite-system-user and give him a special role called system role for instance.
