在Wordpress中将帖子标记为已读

Question

I want to add class (in index) to entry that are been read.

It is possible?

What is best way to do this? Use cookie or session?

I need little help with this ;)

Answer 1

It's quite simple by setting a cookie, you could use the post ID to refer to the post you need to be marked as read. So when clicking mark as read link on the page with the entry just set up a cookie with the post ID and do a check on the overview page if there is a cookie with the post ID of the posts shown.

Also, there seems to be a plugin who can actually do this for you, go take a look at http://pippinsplugins.com/mark-as-read-for-wordpress/
