Leaderboard with Secure $_POST

Hey

i followed this tutorial

construct.net/en/tutorials/creating-own-leaderboard-1032/page-4

someone can enter the url with the parameters and cheat, how can i prevent this?

in the tutorial he says with a hash, but dont the cheater see this hash in F12 console ?

maybe with a $session ?

greetings

In short, it's not possible to prevent cheating if the server just believes what the client tells it. All you can do is try to make it complicated and moderate any obviously invalid score submissions.
