Same statements, the second not working in different if - php

Question

I'm trying to figure out why a mysqli parepared statement is not working. I can say the page have something like 2 sections, the first one needs $_GET to be empty and the last one needs $_GET['id'] and other to be set (isset). Both "sections" have the same query but in the last section there's a different query first.
Everyting is working fine until the repeated query in the last "section", where nothing is printed.
I have something like this:
if (login_check($mysqli) == true) {
if(empty($_GET)) { //first section
if ($stmt = $mysqli->prepare("SELECT friends.*, members.*, account_type.* FROM friends INNER JOIN members ON members.id = friends.friendID
INNER JOIN account_type ON account_type.name = members.acc_type
WHERE friends.userID = ? AND members.acc_type = ?")) {
$stmt->bind_param('is', $_SESSION['user_id'], $_SESSION['acc_type']);
$stmt->execute();
} else echo $mysqli->error;
$result = $stmt->get_result();
// php/mysqli stuff working as expected ($row[] printing db data)
// no need to close
}
if(isset($_GET['id'], $_SESSION['user_id'])) { // last section
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* prepare statement */
if ($stmt = $mysqli->prepare("SELECT COUNT(*) rowCount FROM friends WHERE friendID = ? AND userID = ?")) {
$stmt->bind_param('ii', $_GET['id'], $_SESSION['user_id']);
$stmt->execute();
/* bind variables to prepared statement */
$stmt->bind_result($rowCount);
/* fetch values */
if($stmt->fetch()) {
if ($rowCount > 0) { // This check is working fine, I tested.
$stmt->close(); // close here so no "non-object" error
$stmt = $mysqli->prepare("SELECT friends.*, members.*, account_type.* FROM friends INNER JOIN members ON members.id = friends.friendID
INNER JOIN account_type ON account_type.name = members.acc_type
WHERE friends.friendID = ? AND members.acc_type = ?");
$stmt->bind_param('is', $_GET['id'], $_SESSION['acc_type']);
$stmt->execute();
$result = $stmt->get_result();
$row = $result->fetch_array();
// Here I have some $row['columns'] and nothing is printed.
} else{
echo $_SESSION['username'], ', you are not allowed to be here.';
}
}
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
}
} else {
echo 'Please, log in.';
}
The first query is working fine, the other is a copy/paste.
I don't see where the problem is :(
Thanks!
Edit: sorry the second query should be "WHERE friends.friendID".
for ($i = 1; $i < 13; $i++) {
$month = $row['month' . $i];
if($row[$month] == 1) {
$paid[] = 'Paid';
} else {
$paid[] = 'Not Paid';
}
$bonus = $row['bonus'];
}
The problem is members.monthx and friends.monthx have the same name, but they are not meant to have the same values so I don't know from what table is getting $row['month' . $i]. The value should be taken from friends.monthx. How do I specify that?
