User meta in hidden field

Hey 😁 !
As the title says. How could I get and insert user meta into a hidden field? For example, I have meta “acc_deactivation_status”; “acc_deactivation_pin”. I would like to be able to use placeholders e.g.

{meta:acc_deactivation_status}

so that I don’t have to have a separate php for each meta field.

There are about 140 of them, I plan to use most of them in forms. This way, users could fully manage their account (with Automator). I really want to implement this somehow, but I don’t have much technical knowledge 🙈.

I would be grateful if you could help me!
