User Field Prompt allows you to show a user field form in any Discourse post. Changes made in the form will be saved in the current user profile. It’s useful to ask users to make changes to a user field without having to force them to search the field in their profile.
Usage for a user field named age and another one named best fruits:
My bad the TC was deactivated, it’s now active, I created a new topic: https://dessein-tech.com/t/user-field-prompt-test-2/8406 the frame around the field appears but is not editable. On top of that, the delete button and edit button for that topic do not work (there a delay of 30 seconds before the topic is actually deleted or can be edited). The wrench icon does not react too. This happens in Preview mode too.
I think the problem is that your site is running a legacy version of the post-stream, because discourse-nationalflags has not yet been updated for the new post stream. As an admin, you should be seeing a red banner about that issue.
The recent fixes for user-field-prompt were built only with the new post-stream in mind, so that’s why it’s causing errors on your site.
So if you need this user-field feature right now, I’d recommend disabling the nationalflags plugin. Otherwise, you’ll need to wait for the developer of that plugin to make the necessary updates.
Thanks for bringing this up! Seems like nothing new since then. I know there has been talk about wanting to have custom user fields in TCs before, but nothing yet unfortunately.
