Every time the user makes a post, update their user profile (e.g. whatever table you are using to store user information) to store the date/time of the last post.

Next time a user tries to post, first check how long it has been between the current date, and the last post date. If less than a minute or so has elapsed, fail with a validation error telling the user to wait. Only allow posts after a certain amount of time has elapsed.
