Question

I have a table posts with columns post_id, user_id, post.

When a user visits his page, I retrieve a list of his posts (select post from posts where user_id=$uid). He can then add one or more posts to the table through a form.

Is there any way I can retrieve these newly-added posts without querying the entire table again?

I’m particularly interested in using this with jQuery to auto-refresh his posts periodically (like YouTube comments when ‘auto-refresh’ is selected, for example).

Thanks, Albert

Answer 1

If I were you, I would keep track of when the posts were made, e.g.

post_id, user_id, post, made

You can use AJAX to ping a script to check for posts made since the last ping~
