สอบถามเกี่ยวกับการแอดข้อมูลเข้า Table 4 Table อะค่ะ

$strOrderID = mysqli_insert_id($objCon);
   $strTransID = mysqli_insert_id($objCon2);
  for($i=0;$i<=(int)$_SESSION["intLine"];$i++)
    {
	   if($_SESSION["strid_product"][$i] != "")
	   {
			  $strSQL = "INSERT INTO order_detail (id_order,id_product,Qty) VALUES ('".$strOrderID."','".$_SESSION["strid_product"][$i]."','".$_SESSION["strQty"][$i]."') ";
			  mysqli_query($objCon,$strSQL);

        $strSQL2 = "INSERT INTO send (id_trans,id_order,id_product,Qty) VALUES ('".$strTransID."','".$strOrderID."','".$_SESSION["strid_product"][$i]."','".$_SESSION["strQty"][$i]."') ";
        mysqli_query($objCon,$objCon2,$strSQL2);
