根据if else条件更新行值

Question

在php Page中，一旦单击“ 提交”按钮，就会在数据库中保存订单ID，它的工作正常。...

要求：

如果付款方式为“货到付款”，那么我要在“ awb_type：COD” 行中保存订单ID。...否则在“ awb_type：PPD” 中保存>行。

这是完整的代码，track.php：https://pastebin.com/zLjpee7A，call.php：https://pastebin.com/4LkcxTYE

但是订单在表中更新了两次-PPD中的一行，COD中的一行

如果您需要更多信息，请告诉我。...

更新2：

现在我尝试使用下面的代码，但是什么是payment_type，其仅保存在awb_type列中：PPD行 ....

$sqlc = "select * from ecomexpress_awb WHERE status='unused' AND awb_type='COD' limit 1"; 
$resultc = $db_handle->runSelectQuery($sqlc); 

$sqld = "select * from ecomexpress_awb WHERE status='unused' AND awb_type='PPD' limit 1"; 
$resultd = $db_handle->runSelectQuery($sqld);

$payment_type='';
$sqlg="SELECT * FROM do_order where payment_type='".$payment_type."'";
$resultg = $db_handle->runSelectQuery($sqlg);

if($payment_type=="Cash on delivery")
{
$awb = $resultc[0]['awb']; 
$sqle = "update ecomexpress_awb set orderid = '".$order_id."',status='used' WHERE awb ='".$awb."' limit 1"; 
$resulte = $db_handle->runSelectQuery($sqle);
}
else
{
$awba = $resultd[0]['awb'];
$sqlf = "update ecomexpress_awb set orderid = '".$order_id."',status='used' WHERE awb ='".$awba."' limit 1";    
$resultf = $db_handle->runSelectQuery($sqlf);
}

在我未将Payment_type与order_id绑定之前，以下代码对我有用：

if(isset($_POST['order_id']) && $_POST['order_id']!='')
{ 
$order_id = $_POST['order_id'];  
$payment_type=$_POST['payment_type'];

$sqlg="SELECT * FROM do_order where payment_type='".$payment_type."'";
$resultg = $db_handle->runSelectQuery($sqlg);

if($payment_type=="Cash on delivery")
{
  $sqlc = "select * from ecomexpress_awb WHERE status='unused' AND awb_type='COD' limit 1"; 
}
else
{
  $sqlc = "select * from ecomexpress_awb WHERE status='unused' AND awb_type='PPD' limit 1"; 
}

$resultc = $db_handle->runSelectQuery($sqlc);
