Question

I have this MySQL table:

Let’s imagine I am logged in as user 1 and I’m browsing the profile of user 2. As we are mutual friends (1 is friend with 2 and 2 is friend with 1), I need to echo “friends.”

When I browse the profile of user 4, whose friendship I have requested, but they haven’t accepted yet, I need to echo “friend requested.”

When browsing any other user, I need to echo “add friend.”

I can do the PHP part, I just don’t know how to do the MySQL query.

Answer 1

SELECT COUNT(*) as `count`, `user` 
FROM `friends`
WHERE 
    (`user` = 1 AND `friend` = 16) OR 
    (`user` = 16 AND `friend` = 1)

When count is

• 2 = mutual (you are friend with that person)
• 1 and user is you – you requested that person friendship
• 1 and user is that person – you are being requested for friendship by that person
• 0 = no connection between you and that person
