Add an element to a post with the user ID that clicked on it
-
I would like to add a button in every post that before clicking on it will be gray and after clicking on it will be green for all users !!
This means that as soon as one user clicks on it he will color for everyone.
And that I can know who pressured him ...
Is it possible to insert such an element with the user ID that clicked on it?
