Why does this query get all users? - mysql

Question

so i have this query to determine whether or not it should count towards one entry in a table or not. however, it grabs all the users entries and disobays my
"dc.userid = ". $user ."
in an above query i use to gather what the user actually has inputted. and that works fine. however, when i exclude something it fetches all the entries from every user.
i will provide more code if noone can solve it from here. but i ive set $total above. in my case its 4. one entry should be excluded. but it fetches all entries which arent user = 1 and excludes them. in this case 11, which makes the $total variable -8 and not 3 as it should be. why is that?
$query3 = "SELECT IFNULL(dc.amount, 0) amount, dt.drop_id, dc.drop_id, dc.boss_id, dc.userid, dt.excl
FROM droptable dt
LEFT JOIN dropcounter dc
ON dt.boss_id = dc.boss_id AND dc.drop_id = dt.drop_id AND dc.userid = ". $user ."
WHERE dt.excl = 1 AND dc.userid = ". $user ."";
$stmt = $pdo->prepare($query3);
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
foreach($result as $row){
$amount = $row['amount'];
echo $amount;
echo "<br>";
if (empty($amount)){}
else {
$total -= $amount;
}
}
echo $total;
