Populate drop down with existing users first and last name as one option

I'm looking at:

http://www.gravityhelp.com/documentation/page/Using_Dynamic_Population
http://www.gravityhelp.com/documentation/page/Allow_field_to_be_populated_dynamically

and I still can't figure out how to populate a drop down with first name and last name of registered users in wordpress.

Any hints?

Precisely.

Dana send me some code example yesterday through priority support, which I will try when I get home. Sorry for the double posting. This one started a long time ago.

Should I post the solution here if I get it to work?

Yeah, I'm sorry about that. I waited two weeks in here before going priority. Dana sent me:

"To dynamically populate your drop down with users, you need to check the option on the Advanced tab called "Allow field to be populated dynamically" for your drop down field. You do not provide a parameter name. You will use the gform_pre_render filter in your functions.php file. I have created an example for you which uses the WordPress function "get_users()" to get users. :)

Take a look at the example here: http://pastie.org/4751675 .

The WordPress documentation for the get_users function can be found at http://codex.wordpress.org/Function_Reference/get_users - in case you want to add more filtering to the get_users function than what I used in the example.

The documentation for the gform_pre_render function can be found at http://www.gravityhelp.com/documentation/page/Gform_pre_render . I used the examples here as my basis for building the function for populating a drop down with user information."

When you set up the drop down, you will be shown display_name, which wasn't quite what I wanted.

I found that I could change that when I connected the form to user registration and set the shown name to last name/first name in there.

Then I have my last and first name in the drop down :)
