Question

我想在循环之后添加一行，根据用户的订单，LAST行之前的行数是随机的。所以例如用户订购10，我想在列表中添加另一行。即使订单为3，最后仍会有另一行。

while ($row=mysql_fetch_array($result)){
echo "<tr>";
echo "<td>".$row['prod_name']."</td>";
echo "<td>".$row['quantity']."</td>";
echo "<td>₱".number_format(($row['price']*$row['quantity']),2)."</td>";
echo "</tr>";
        if($row['carrier']=="LBC"){
        echo "<tr>";
        echo "<td>Shippment Option Chosen: ".$row['carrier']."</td>";
        echo "<td></td>";
        echo "<td>₱250.00</td>";
        echo "</tr>";
            }
    }
echo "</table>";
?>

在这里，我创建了另一行，但它在每行之后创建了一行，我只需要在表的末尾添加1行。谢谢:)）

Answer 1

您应该在

之前添加一行

echo "</table>";

行，但在它之前的结束括号之后。最后一个结束括号是你的循环结束的地方。它应该是这样的：

while ($row=mysql_fetch_array($result)){
echo "<tr>";
echo "<td>".$row['prod_name']."</td>";
echo "<td>".$row['quantity']."</td>";
echo "<td>₱".number_format(($row['price']*$row['quantity']),2)."</td>";
echo "</tr>";
        if($row['carrier']=="LBC"){
        echo "<tr>";
        echo "<td>Shippment Option Chosen: ".$row['carrier']."</td>";
        echo "<td></td>";
        echo "<td>₱250.00</td>";
        echo "</tr>";
            }
    }
  echo "<tr>";
  echo "<td>LAST LINE...</td>";
  echo "<td></td>";
  echo "<td></td>";
  echo "</tr>";
  echo "</table>";
?>

Answer 2

您可以使用mysqli_num_rows获取否。的行。然后你可以在while循环中添加一个计数器。当counter = mysqli_num_rows时，你可以回显你想要回显的行

示例：

$totalrows=mysqli_num_rows($result);
$counter=1;
while ($row=mysql_fetch_array($result)){
    //echo the row data
if($counter==$totalrows)
    {
    //echo the extra row which you wanted.
    }
}
echo "</table>";

嗯为什么不添加新查询？我修改了你的代码。并添加了这些。

$qryx = "SELECT DISTINCT customers.serial,customers.name,customers.payment,customers.carrier,customers.tracking_no, orders.date, order_detail.productid, order_detail.quantity, order_detail.price, order_detail.orderid, inventory.prod_name 
        FROM customers 
        RIGHT JOIN orders on customers.serial=orders.serial 
        RIGHT JOIN order_detail on orders.serial=order_detail.orderid 
        LEFT JOIN inventory on order_detail.productid=inventory.prod_id
        where customers.email='{$_SESSION['email']}' 
        AND order_detail.orderid='{$_REQUEST['orderid']}'
        GROUP BY customers.carrier";

$resulty = @mysql_query($qryx);
while ($rowz=mysql_fetch_array($resulty)){

    if($rowz['carrier']=="LBC"){
        echo "<tr>";
        echo "<td>Shippment Option Chosen: ".$rowz['carrier']."</td>";
        echo "<td></td>";
        echo "<td>₱250.00</td>";
        echo "</tr>";
            }
        }

我更改了qry，result和row的名称。并添加了DISTINCT和GROUP BY来删除冗余。

如何在循环结束时添加另一个表ROW。
