<?php session_start();
include ("config/connect.php");
 	  $Total = 0;
	  $SumTotal = 0;
		for($i=0;$i<=(int)$_SESSION["intLine"];$i++)

				  {
					$strSQL = "SELECT * FROM products WHERE products_code = '".$_SESSION["strProductsCode"][$i]."'";
					$objQuery = mysql_query($strSQL)  or die(mysql_error());
					$objResult = mysql_fetch_array($objQuery);
					$Total = $_SESSION["strQty"][$i] * $objResult["products_price"];
					$SumTotal = $SumTotal + $Total;
				  }
		  	}
			
	$numSQL = "SELECT `order`.order_id FROM `order`";
	$numQry = mysql_query($numSQL);
	$numTotal = mysql_num_rows($numQry);		
	$order_date = date("Y-m-d h:i:s");
	$date_code = date(s);
	$order_num = $numTotal+1;

	$query = mysql_query($sql) or die(mysql_error());
