Check if the user posted comment on a post

Question

Hi

How can I check if the visitor who is currently reading a post has written a comment on that post?

Answer 1

There's no 100% way to do this, but the best way would be to set a cookie with the ID of the post that they commented on, and check that when they visit. There just might be a Wordpress plugin that does that already, but I don't know for sure; Google it.
