I need to generate a unique ID number for each new member. I was going to use WP_query, but am not getting anything but an array.
If you want to display the info on the current user logged in you can use
Example from Codex
Or if you want display the info for a user that is not the current user logged in, you can use
The two links to the WP Codex should provide you with the syntax of the two functions. If you have any further questions or they did not work please ask.
