hi all,
i am doing a shopping cart example.after the shopping is complete it is mandatory for the user
to fill his details.so that it will go in to database.
i have written my both php and javascript code but the "billing.php" is not taking in the database
PHP Code:
<?php
include("db.php");
include("functions.php");
if($_REQUEST['command']=='update')
{
$name=$_REQUEST['name'];
$email=$_REQUEST['email'];
$phone=$_REQUEST['phone'];
$result=mysql_query("insert into customers values('','$name','$email','$phone')");
$customerid=mysql_insert_id();
$date=date('Y-m-d');
$result=mysql_query("insert into orders values('','$date','$customerid')");
$orderid=mysql_insert_id();
    
$max=count($_SESSION['cart']);
for($i=0;$i<$max;$i++)
{
  $pid=$_SESSION['cart'][$i]['productid'];
  $q=$_SESSION['cart'][$i]['qty'];
  $price=get_price($pid);
  mysql_query("insert into order_detail values($orderid,$pid,$q,$price)");
}
 die('Thank You! Your Order Has Been Placed!');
}
?>
below is my javascript code.....
