无需用户登录即可跟踪喜欢

Question

The blog of my website allows liking the posts. But this is only for users who signup. So if some new user likes a blog post , I won't be able to record his like .

My questions is how can I keep track whether a visitor has liked a blog or not without signing up ?

Answer 1

I guess you could record their 'like' in a cookie so they can't (note 1) 'like' the same post more than once. You'd need to check for the cookie value of course.

Note 1: There's no guarantee that the user (or robot) has cookies enabled though, so it's impossible to stop multiple 'likes'. It depends how important this is to you.
