Question

I’m having a lot of problems getting mutual friends between users and displaying those mutual friend’s picture, userid and names in a while loop. I have tried nearly every answer on SO on mutual friends but when I mix all of the column’s needed for the while loop, everything breaks down. Any help would be much appreciated.

Friends Table:friend_id, friend_one, friend_two, date

Users table: uid, name_f, name_l, profile_pic

When users add one another as friends, I record the following. Let’s assume that user 1 and user 2 are now friends:

friend_one: 1, friend_two: 2, Date

friend_one: 2, friend_two: 1, Date

I would need something like the following, the sql query only return the number of mutual friends for me but doesn’t help me select the user’s uid, profile pics and names:

$friends_sql=mysql_query("SELECT b.friend_two FROM (SELECT friend_two FROM friends WHERE friend_one = $myvar1) a INNER JOIN (SELECT friend_two FROM friends WHERE friend_one = $myvar2) b ON a.friend_two = b.friend_two");
                while($friends=mysql_fetch_array($friends_sql))
                {
                something
                ?>
                <li>


 <img of user><p>name of user</p><a hre>link to user's uid</a>
</li>

                <?php
                }
                ?>

Does the next code works for you?

$friends_sql=mysql_query("SELECT b.friend_two FROM (SELECT friend_two FROM friends WHERE friend_one = $myvar1) a INNER JOIN (SELECT friend_two FROM friends WHERE friend_one = $myvar2) b ON a.friend_two = b.friend_two");
                while($friends=mysql_fetch_array($friends_sql))
                {
                     $getMutualFriendInfo = mysql_query("SELECT * FROM users WHERE uid='{$friends['friend_two']}'");
                      $MutualFriendInfo = mysql_fetch_array($getMutualFriendInfo);
                ?>
                <li>


 <img src="<?=MutualFriendInfo['profile_pic']?>"><p><?=MutualFriendInfo['name_f'] ?> <?=MutualFriendInfo['name_l'] ?></p><a href="/user.php?uid=<?=MutualFriendInfo['uid'] ?>"></a>
</li>

                <?php
                }
                ?>
