running a query inside a loop to do another loop - php

Question

Ok so what i am doing is getting member id's from 1 table and looping those ID's through another table to get values to output. I had it working going through the first loop, then notice the output was all screwy, so released I needed to loop it through again, since there will could be multiple entries in the 2nd query for MemID. now I put in the 2nd loop but its not even going through, not sure where I messed up the code, but doesn't seem to output now when running it through the 2nd loop. though it did output without the loop. but that won't work due to multiple rows for each $memid.
$qry_skamembers = "SELECT * FROM ap_skamembers ORDER BY id";
$qry_skamembers = $mysqli->real_escape_string($qry_skamembers);
if($result_skamembers = $mysqli->query($qry_skamembers)){
while($row_skamembers = $result_skamembers->fetch_array()){
$AffID = $row_skamembers['AffID'];
$MemID = $row_skamembers['MemberID'];
$skacon = new mysqli(OW_DB_HOST, OW_DB_USER, OW_DB_PASSWORD, OW_DB_NAME);
if ($skacon->connect_error) {
die('Connect Error');
}
$get_data = "SELECT * FROM ow_base_billing_sale WHERE userID = $MemID AND status = 'delivered' ORDER BY id";
$get_data = $skacon->real_escape_string($get_data);
if($result_data = $skacon->query($get_data)){
while($finish = $result_data->fetch_array()){
$test = $finish['status'];
if($test == 'delivered') {
$sale_amount = $finish['price'];
$product = $finish['transactionUId'];
$products = mysqli_fetch_assoc(mysqli_query($mysqli, "SELECT * FROM ap_earnings where product = $product"));
if(mysqli_num_rows($products) > 0) { }
else {
echo "AFF: " . $AffID . " | ";
echo "Mem: " . $MemID . " | ";
echo "PRICE: " . $sale_amount . " | ";
echo "PRODUCT: " . $product . " -- ";
include('controller/record-sale.php');
echo "inserting record";
echo "run finished <br><br>";
}
}
}
}
}
}
I am still rather new at coding, so it might look a bit sloppy, my apologies for that.

Answer 1

I do not know if that is ist bu try to replace:
$get_data = $skacon-->real_escape_string($get_data);
with
$get_data = $skacon->real_escape_string($get_data);
i think there is an extra -
And as we found out in comments you need to change $product to '$product'

Answer 2

You can do all that in one query,nevermind it will be much faster
SELECT aps.AffID,aps.MemberID,owb.price,owb.transactionUId
FROM db1.ap_skamembers aps JOIN db2.ow_base_billing_sale owb
ON aps.MemberID = owb.userID AND owb.status='delivered'
JOIN db3.ap_earnings ape
ON ape.product = owb.transactionUId
ORDER BY aps.id
