Is it possible to update an entry’s Users field from the front-end? If so, how would you go about it?
The situation is this: training events are created and then posted for members to bid on for a limited number of spots. Logged in members review the available events and add their name (would use their ID) to each event of interest. Admins then manually chose a select few from all submissions.
I know I can do this by adding their IDs to a text field in the event section, and then using Split to create an array, but the Users field approach is much more elegant and offers more flexibility.
