I'm creating a booking calendar and am having issues making the timeslots that have been booked unavailable. I have populated them separately unfortunately, so the date and timeslot have no connection.
How do I check if both the timeslot and date (in the same ID) have been booked?
$name = $_POST['name']; 
$email = $_POST['email']; 
$timeslot = $_POST['timeslot']; 
$date = $_POST['date']; 
$conn = new mysqli("localhost","root","root","bookingCalendar");
if($conn->connect_error){
    die("Failed to connect : ".$conn->connect_error);
    } else {
        
    $stmt = $conn->prepare("insert into bookings(name, email, timeslot, date) values(?, ?, ?, ?)");
    $stmt->bind_param("ssss", $name, $email, $timeslot, $date); //Saves values as strings, thus further functions can't be created
    $stmt->execute();
    echo '<script>alert("Booking successful!")</script>'; 
    echo "<script> location.href='bookCal.php'; </script>";
    $stmt->close();
    $conn->close();
}
