Retrieving a User’s Friends’ Listings

Problem

I need to retrieve all of a specified user’s friends’ listings using FQL.

Solution

SELECT title, url, description, price, category FROM
 listing WHERE poster IN (SELECT uid2 FROM friend WHERE uid1 = $user);

Discussion

Since this is based on a query on the friend table, you can make it only when user is the current loggedinuser.
