Problem with coding MySQL query

I'm having heaps of trouble getting one of my PHP/MySQL queries to work for some reason (and the funny thing is there are plenty that are identical to it all the way through the site) so I'm wondering if someone can spot the problem. (I've basically torn all the code apart trying to work it out and have changed values that are being submitted, etc to try and get it to work, so I'm tearing my hair out now!)
Code: $staffID = $_POST['staffID'];
$date = date("Y-m-d h:i:s");
$sql2 = "INSERT INTO Order (date, staffID)
VALUES ('$date', '$staffID')";
$result2 = mysqli_query($cxn, $sql2)
or die ("Couldn't execute insert into order query.");
As it's not working, I keep getting "Couldn't execute insert into order query."
The MySQL database is named Order, and has orderID, date and staffID. orderID is int(8 ), unsigned zerofill and autoincrement. date is datetime, and staffID is int(4) unsigned zerofill. Staff members enter the zeros in their staffID when putting their details into the form (so would enter 0004).
Here's the full code:
createorder.php
Code: <?php
include("credentials.inc");
switch (@$_POST['do']) {
case "neworder":
$cxn = mysqli_connect($host, $user, $password, $dbname)
or die ("Connection failed.");
$staffID = $_POST['staffID'];
$sku = $_POST['sku'];
$quantity = $_POST['quantity'];
$sql = "SELECT staffID FROM Staff
WHERE staffID = '$staffID'";
$result = mysqli_query($cxn, $sql)
or die ("Couldn't execute staff query.");
$num = mysqli_num_rows($result);
if ($num > 0) { //staff member found
$date = date("Y-m-d h:i:s");
$sql2 = "INSERT INTO Order (date, staffID)
VALUES ('$date', '$staffID')";
$result2 = mysqli_query($cxn, $sql2)
or die ("Couldn't execute insert into order query.");
$sql3 = "SELECT orderID FROM Order
WHERE date = '$date'";
$result3 = mysqli_query($cxn, $sql3)
or die ("Couldn't execute select from order query.");
$rowname = mysqli_fetch_assoc($result3);
extract ($rowname);
$sql4 = "INSERT INTO ItemsOrdered (orderID, sku, quantity)
VALUES ('$orderID', '$sku', '$quantity')";
$result4 = mysqli_query($cxn, $sql4)
or die ("Couldn't execute insert into ItemsOrdered query.");
header("Location: success4.php");
}
else {
$message = "Staff member does not exist.<br />";
include("createorder.inc");
}
break;
default:
include("createorder.inc");
}
?>createorder.inc
