ID to only appear if value is not null

phpanon · March 11, 2008

Hello there.

I have a list of orders in a table. Some orders that were previously rejected but then re-submitted have a formerID that relates to the rejected order.

What I want is that if an order has a formerID then display that to the user, if not then display "no related orders" or something.

Here is my code

<?php
session_start();
if (isset($_SESSION['username']) == false){
	header("Location: login.php");
	exit();
}

require "connect.php";
$query = "SELECT DISTINCT o.orderID, p.formerID FROM orders o, productorder p WHERE p.orderID = o.orderID AND p.status = 'Complete' AND o.empID = ".$_SESSION['empID'];
$result = mysql_query ($query, $connection) or die ("Unable to perform query<br>$query");
?>
<!DOCTYPE HTML PUBLIC "//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Past Orders</title>
<link rel="stylesheet" type="text/css"
href="mystylelogin.css" />

</head>
<body>

<?php
switch ($_SESSION['type']) 
{
	case 'user':
    	include ("header.php");
	include ("StationaryMenu.php");
    	break;
  
	case 'admin':
	include ("headerAdminMain.php");
	include ("StationaryMenu.php");
	break;

	case 'manager':
	include ("header.php");
	include ("StationaryMenuManager.php");
	break;
}
?>

<div id="header">Past Orders</div>

<div id="OrdersBasketTable">
<table border="0" width="100%">
<hr />
<tr>
	<th width="100">Order Number</th>
	<th colspan="2" align="right">Related Orders</th>
</tr>
<?php
while($row=mysql_fetch_array($result))
{ $total2 = 0; ?>
	<tr>
		<td align="center"><h2><strong><?php echo $row['orderID']?></strong></h2></td>
		<td>
		<table border="0"width="100%">
		<tr>
			<th width="25%" align="left">Product</th>
			<th width="10%" align="left">Price</th>
			<th width="10%" align="left">Quantity</th>
			<th width="18%" align="left">Date Made</th>
			<th width="14%" align="left">Date Approved</th>
			<th width="13%" align="left">Total</th>
		</tr>
		<tr>

<?php
$query2 = "SELECT * FROM orders o, productorder e, product p WHERE o.orderID = e.orderID AND p.URN = e.URN AND e.status = 'Complete' AND o.orderID = '".$row['orderID']."'";
$result2 = mysql_query ($query2, $connection) or die ("Unable to perform query<br>$query2");

			while($row2=mysql_fetch_array($result2))
			{ ?>
  		  <tr>
					<td><a href="productOrder.php?URN=<?php echo $row2['URN']?>"><?php echo $row2['productName']?></td>
					<td>£<?php echo $row2['price']?></td>
					<td align="center"><?php echo $row2['quantity']?></td>
					<td><?php echo $row2['date']?></td>
					<td><?php echo $row2['apprDate']?></td>

					<?php $total = $row2['quantity'] * $row2['price']; ?>
					<td>£<?php echo $total ?></td>
					<?php $total2 = $total2 + $total ?>
					<td><?php echo $row['formerID'];?></td>
  		  </tr>
				<?php
			} ?>
			</td>
			</tr>
			<td></td>
			<td></td>
			<td></td>
			<td></td>
			<td></td>
			<td></td>
			<td><strong>Total</strong></td>
			<td>£<?php echo $total2 ?></td>
			<td></td>
  </table>
			<?php
	} ?>
</table>
</td>
</table>
</div>
</body>
