Formspec Hidden Field or Data

[runs]

I need send data (hidden) to a formspec and then recover it thru 'minetest.register_on_player_receive_fields' to act in consequence. This is because the player is not a node nor a player, is a entity.

I know about ActiveFormspec mod adding a hidden field to a formspec. But without any dependency is there another simple method?

Hidden fields are insecure, and should never be used. You should use a context instead, as explained here: https://rubenwardy.com/minetest_modding ... l#contexts
