A filter, useful in a page or block, for showing and storing a button state (once). Such as when you want to enter a draw, or vote for one thing. Probably not a lot of use-cases for this one.
html can go here before
[[ENTERDRAW:START]]
Put in the stuff you want to appear when the button hasn't been pushed
[[ENTERDRAW:BUTTON The button text goes here]]
[[ENTERDRAW:ELSE]]
Your vote counts! Get your socks on, it's going to be a wild ride.
[[ENTERDRAW:END]]
html can go here too
Logs an event when the user clicks the button, and stores the state in the user preferences.
How does the user or the teacher reset or unsubmit the link? ¯\_(ツ)_/¯
