updating a record based on id and checkboxes - php

Question

Essentially, i'm trying to show the information about what the user has it lists their
BookID date time confirmed
confirmed is a 0 or 1, 0 is not confirmed 1 is confirmed, as this is a table this needs to be done with $_GET i'm assuming or it wont update the correct one.
at the moment I have this for the table listing the things
<?php
while($row = mysqli_fetch_array($result))
{ ?>
<tr>
<td><?php echo $row['BookID']?></td>
<td> <?php echo $row['date']?> </td>
<td> <?php echo $row['time']?> </td>
<td> <input type="checkbox" name="Confirmed" value="1" <?php echo ($row['Confirmed'] == 1) ? 'checked="checked"' : ''; ?>/> </td>
<td>Delete</td>
<td>Update</td>
</tr>
</table>
update.php contains this
<?php
// Your database info
$db_host = 'localhost';
$db_user = 'root';
$db_pass = '';
$db_name = 'smithrwg_database';
$Confirmed = $_POST['Confirmed'];
if (!isset($_POST['Confirmed']))
{
echo 'No ID was given...';
exit;
}
$con = new mysqli($db_host, $db_user, $db_pass, $db_name);
if ($con->connect_error)
{
die('Connect Error (' . $con->connect_errno . ') ' . $con->connect_error);
}
$sql = mysql_query("UPDATE tbl_booking SET Confirmed = '$Confirmed' WHERE BookID = ?");
//$sql = "UPDATE tbl_booking SET Confirmed='$Confirmed' WHERE BookID == ?";
if (!$result = $con->prepare($sql))
{
die('Query failed: (' . $con->errno . ') ' . $con->error);
}
if (!$result->bind_param('i', $_GET['BookID']))
{
die('Binding parameters failed: (' . $result->errno . ') ' . $result->error);
}
if (!$result->execute())
{
die('Execute failed: (' . $result->errno . ') ' . $result->error);
}
if ($result->affected_rows > 0)
{
echo "The ID was updated with success.";
}
else
{
echo "Couldn't update the ID.";
}
$result->close();
$con->close();
with my main focus being on the $sql, as it isnt actually getting the id from the get function.
the checkbox is getting the value from the database to see if it should be checked already or not, i want to be able to click it again and "un-confirm" or confirm it if it didn't have a tick.

What did you use for method attribute in your form tag? If you use GET, then use a GET to fetch it. If you use POST, then use a POST. By the way, try to echo all of the posted variables first so that you know that you are passing correct variable. It is always a good debugging method. Hope this helps. Thank you.
