How to echo out mysqli aliased columns? - php

Question

Having issues echoing out the sql columns because I want to output the two
aliased columns that come out of an sql statement whereby I'm doing calculations on certain rows.
I have tried the below code and also by modifying it by replacing the 0 and 1 with the aliased column names, AmountOwed, KindsOfProducts which didnt work.
PHP CODE - where the issue is...
$result = $con->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
echo "AmountOwed: " . $row[0]. " - KindsOfProducts: " . $row[1]
."<br>";
}
} else {
echo "0 results";
}
$con->close();
The Messy SQL statement I'm trying to echo
#$username=$_POST['username'];
$sql= "SELECT SUM(`price` * `quantity`) AS AmountOwed,
COUNT(*) AS KindsOfProducts FROM tablename
WHERE `orderdate` BETWEEN DATE_SUB(NOW(), INTERVAL 30 DAY) AND NOW()
and uname = '$username'";

Answer 1

The original method I found on Stack was to echo row[0] etc, replace the 0 with the column alias.
Only reason why this didnt work initially was it had a small typo in there, here's the correct code.
$result = $con->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
echo "TEXT: " . $row[COLUMNALIAS]. " - MORETEXT: " . $row[COLUMNALIAS]
."<br>";
}
} else {
echo "0 results";
}
$con->close();
