Here is the query. Basically i am passing two parameters user_id (logged in user) and friend_id so the query will fetch all friends imagine you are click on your own friend and seeing the friend on another screen some are mutaul friend.. in this query mutaul is fine.. but when i want to follow the person that is not followed by the firned_id i need that to be true when there is exists data against the user_id
here im checkign relationship between user_id=334 and friend_id=312 image i have friend_id have these friend 1,2,3 and user(logged in user) has 3, 4, 5 now 3 is mutal friend that is toally fine and my ismutaul=1
now there is a record against the friend 2 in followers table in database so friend 2 actually is the friend of 312 and 312 not following. so how can i make it true because 334 is already follwoing him i need the isfollower varaible to be true.
im stuck and i dont know what to do any help please?
