update row value based on if else condition
2
In php Page once we click on "Submit" button , in database we are saving order id, its working fine....
Requirement :
If payment is "Cash on delivery" , than i want to save order id in "awb_type : COD" row.... otherwise in "awb_type : PPD" row....
here is full code , track.php : https://pastebin.com/zLjpee7A , call.php : https://pastebin.com/4LkcxTYE
But orders are updating twice in table - one row in PPD & one in COD
Please let me know if you need more information....
Update 2 :
Now i tried below code, but whatever is payment_type , its saving only in awb_type column : PPD rows....
$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);

BTW if you have multiple users on your system simultaneously then this system of picking the next unused slot is going to result in contention - i.e. people selecting and/or updating the same rows as each other. e.g. user1 runs select, slot 23 was available, but user2 also runs and gets slot 23 as available, then user1 runs update, and then user2 runs update (and thus overwrites user1's data). It would be better to just create the AWB records at the time you need them, surely, instead of creating them ahead or time. That or you have to find a way to lock the rows.

Before I did't binded the payment_type with order_id, below code worked for me :
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";
