This doesn’t seem to have anything to do with WordPress, but the problem is simple: You’re still using $_POST['quantity']
outside of isset()
.
You’re checking isset()
here:
if(isset($_POST['quantity'])) {
$quantityinstock = $_POST['quantity'];
}
But then you’re immediately using it without the check anyway:
$quantityinstock = $dbConn->escape_string($_POST['quantity']);
You should not be using $_POST['quantity']
without a check for isset()
.
