I want to extend the author profiles within wp, making it possible for authors to add address, zip code, city, birthday etc.
I modded the profile.php file, and the fields I've created appear online in the profile page, but the content I enter isn't being reproduced when I click the 'update profile' button.
So I figured something else should be changed.
I then looked in the template-functions-author.php file and saw I could define includes, and so I added the ones of the fields I've created, but still no results.
Then I saw the registration-functios.php file where I could add stuff in the update_usermeta list.
Still no result.
My question is: what should I change to make wp 1. remember what has been inputted in the fields I've created and 2. reproduce it correctly when the settings are saved.
