I have been trying to get your suggested code working however I can’t seem to get it to work or format it correctly.
Your SQL works brill just one tweak as I had to rename BOOL to BIT which works just like Boolean in SQL.
I have also reworked my code for a good few hours today and I believe the issue is something to do with the HTTP POST from the Arduino. I found that by removing the POST[volData] that it would then upload the POST[gaiData] instead.
However since this development I have changed my code some more and broken it again. From the serial Monitor I get HTTP Request code 200 for all the values sent to the webpage however when I call the POST attribute in the PhP it doesn’t input anything. Any Ideas why this is? I know the database is set up right as everything is set to integers. But not 100% sure about the Arduino or PhP side.
I have also made the code to run not just of the analog read input but random strings of numbers too.
Any Ideas on this?
Php Code

error_reporting(E_ALL);
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "Pre-Play";
$conn = mysqli_connect($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Database Connection failed: " . $conn->connect_error);
}
if(!empty($_POST))
{
$volume = $_POST['VolValueSend'];
$gain = $_POST['gaiCode'];
$treble = $_POST['treCode'];
$bass = $_POST['basCode'];
$contour = $_POST['conCode'];
echo "Post Results";
echo $volume;
echo $_POST['VolValueSend'];
$sql = "INSERT INTO retrieve (volume)VALUES ('".$volume."')";
if ($conn->query($sql) === TRUE) {
echo "OK";
} else {
echo "Error: " . $sql . "
" . $conn->error;
}
}
// $sql = "INSERT INTO retrieve (volume,gain,treble,bass,contour)VALUES ('".$volume."','".$gain."','".$treble."','".$bass."','".$contour."')";
// if ($conn->query($sql) === TRUE) {
// echo "OK";
// } else {
// echo "Error: " . $sql . "

// }
// }
$conn->close();
