Question

I’m not getting any data, and I’ve checked my dad which should match up

I have two tables, likes and user_follow
I’m trying to tie the two tables by an id.

Table – Column

likes – idlikes, iduser, information
user_follow – iduser_follow, iduser_follower, iduser_following

$following = $dbh -> prepare("SELECT L.* FROM likes L JOIN user_follow F ON F.iduser_following = L.iduser WHERE F.iduser_follower = ?");
$following->execute(array($_SESSION['user_auth']));
while($row_following = $following->fetch(PDO::FETCH_ASSOC)){
     $id_1 = $row_following['L.information']; // get id of user that i'm following
     echo $id_1;
}

So if i’m following someone, i should be able to display information associated with whomever I’m following.

I don’t get any errors, it just doesn’t echo out anything?

Sample Data

user_follow

iduser_follow           iduser_follower            iduser_following
     1                         2                        3
     2                         2                        4

likles

  idlikes                   iduser                  information
     1                         3                        info1
     2                         3                        info2

So, I should output info1 and info2, assuming that $_SESSION[‘user_auth’] = 2, correct?

Answer 1

SELECT  b.*
FROM    user_follow a
        INNER JOIN likes b
            ON a.iduser_following = b.iduser
WHERE   a.iduser_follow = 'myuserID' AND
        iduser_following = 'followingID'

and fetch value

$id_1 = $row_following['information'];
