Showing extra profile fields in admin - problem with underscore

Question

I am saving extra profile fields to my users' profiles - not via User admin but via another method (a plugin, but that's not important - all the user data is there properly).

Now I do also want to show the extra info on User profiles in the admin backend, and make them editable there, too. I have followed the Justin Tadlock code at http://justintadlock.com/archives/2009/09/10/adding-and-using-custom-user-profile-fields - that means I have added some actions and two functions to functions.php, to support displaying and updating these fields on the backend.

The problem is, fields whose names include underscores are not returning results properly.

ie. Whilst I can properly return the value of "company", the value of "company_url" is also returned as though it were "company" (eg. "Microsoft" instead of "http://www.microsoft.com").

My two functions are below. I haven't yet updated the save function as this would just corrupt the User data with a duplicate of the "company" value. I have many field names containing "_", so this will be important.

 add_action( 'edit_user_profile', 'mysite_show_extra_profile_fields' );

Answer 1

You really should rename your field names with a hyphen (-) instead of an underscore. There is no solution for that other than replacing the underscores (_) for the hyphens (-) I read somewhere that the problem is with the new php naming conventions and when used in functions, it separates the words when an underscore is used. And since Wordpress uses php in its core functions, it is still a bug. I am sorry, that your problem couldn't be solved, but if the form is the only place where your fields

Answer 2

Follow-up - this was not about an underscore problem. The problem was mine. The value of company_url matched the value of company. That was my fault for incorrectly duplicating the data by import. This was fixed by reimporting properly.
