php - Display friend post according to the friend connected to each other? -

-

i have 2 tables in mysql frnd_request , nsm_post want show post according user share post primary school mate , secondary school mate etc.

frnd_request table referece column user connected each other. table structure below

1 id      2 user_id     3 frnd_id     4 status      5 referece  (how friend connected each other primay, secondary school mate)  6 confirmation    7 note  8 date

nsm_post post table show_to field define friend group of logged in user can see post.

1   id    2   uid (user id of user posted post)  3   post       4   ip      5   show_to (to friend group post display)  6   img_video_name      7   date 

select nsm_post.post  frnd_request, nsm_post frnd_request.user_id = nsm_post.uid

this should work. guess trying restricting posts user's school mates. not possible current table structure. have setup additional table this:

primary | uid1 | uid2 | type

0 | 10004 | 10005 | school mate
