ช่วยดูโค็ตให้หน่อยครับ Action ไปหน้า order_save แต่พอรับมันรันไป order

<?
	include('conn_mysql.php');
	
	$product_id = $_POST["product_id"];
	$date = date("Y-m-d");
	
	
		
	for($i=0;$i<count($product_id);$i++)
	{		
		$num = "num".$product_id[$i];
		$num = $_POST["$num"];
		$total = "total".$product_id[$i];
		$total = $_POST["$total"];
		
		mysql_db_query($dbname , "insert into order (date,customer_id,pricetotal) VALUES ('$date','$customer_id','44')") or die(mysql_error()); 
		mysql_db_query($dbname , "insert into order_details (order_no,product_id,quantity) VALUES ('1','$product_id[$i]','$num')") or die (mysql_error());
		echo "<script>alert('บันทึกข้อมูลเรียบร้อย');</script>";
	}

	echo "<script>window.location='order.php';</script>";
	mysql_close();   
?>
