Need help with custom eval code field

[TalkVirginia]

I'm working on an addon for vb3.8.6. I have my development site in debug mode and in the admin cp I'm trying to add an option that will have 2 text fields and a button. The button would execute some ajax code that would return some xml. The xml should then be formatted and displayed as a dropdown with a list of names. The admin should be able to select a name and save it to a custom table.

Is there anyone that could help me with this or point me in the right direction. Maybe an example somewhere to get me started?

Thanks in advance,
Jim

The pm sending page uses something similar - it calls ajax.php?do=usersearch so you might want to look at ajax.php (maybe you can even use it as is if you need to look up member names).

You could probably look at the HTML source for the pm send page to see how the client side is done.
