Question

basically i have this problem i have a table of posts(in my mysql database)

Post{user_id, post, vote_up(int), vote_down(int)}

because users log in, then they get to vote, but i wanted to check if the user has already voted, so then i can not allow them to vote again, and obviously im going to be using user session to control this oppose to tracking ips etc.

so i was thinking do i have to create another table or is thier a better approach.

Answer 1

You will need another table e.g. called “votes”:

Vote{user_id, post_id}

I assume, that your “Post” table has a primary key (e.g. “id”) that you have not shown in your question above? Then “post_id” should be a foreign key to Post#id.
