zencart针对paypal防漏单方法(2)_zencart教程_php教程

如果顾客返回修改了购物车，再次到达checkout_payment时$_SESSION['order_number_created']将被清除，

其实，生成订单的代码可以写在modules/payment/paypal.php的 function confirmation()中。

代码如下：

function confirmation() {

if(!isset($_SESSION['order_number_created']))

{

global $order,$order_total_modules,$order_totals,$zco_notifier,$insert_id;

$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_BEGIN’); // if the customer is not logged on, redirect them to the time out page

if (!$_SESSION['customer_id'])

{

zen_redirect(zen_href_link(FILENAME_TIME_OUT));

}

else

{ // validate customer

if (zen_get_customer_validate_session($_SESSION['customer_id']) == false)

{

$_SESSION['navigation']->set_snapshot(array(‘mode’ => ‘SSL’, ‘page’ => FILENAME_CHECKOUT_SHIPPING));

zen_redirect(zen_href_link(FILENAME_LOGIN, ”, ‘SSL’));

}

if(isset($mycartID)&&$mycartID == $_SESSION['cart']->cartID)

{

return array(‘title’ => MODULE_PAYMENT_PAYPAL_TEXT_DESCRIPTION);

}

$mycartID = $_SESSION['cart']->cartID;

$order = new order; // prevent 0-entry orders from being generated/spoofed

if (sizeof($order->products) < 1)

{

zen_redirect(zen_href_link(FILENAME_SHOPPING_CART));

}

$order_total_modules = new order_total;

$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_BEFORE_ORDER_TOTALS_PRE_CONFIRMATION_CHECK’);

//$order_totals = $order_total_modules->pre_confirmation_check();

$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_BEFORE_ORDER_TOTALS_PROCESS’);

$order_totals = $order_total_modules->process();

$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_ORDER_TOTALS_PROCESS’);

if (!isset($_SESSION['payment']) && !$credit_covers)

{

zen_redirect(zen_href_link(FILENAME_DEFAULT));

} // load the before_process

// load the before_process function from the payment modules

//$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_PAYMENT_MODULES_BEFOREPROCESS’);

// create the order record

$insert_id = $order->create($order_totals, 2);

require(DIR_WS_LANGUAGES.’english/email_extras.php’);

require(DIR_WS_LANGUAGES.’english/checkout_process.php’);

// store the product info to the order

$order->create_add_products($insert_id);

$_SESSION['order_number_created'] = $insert_id;

$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_ORDER_CREATE_ADD_PRODUCTS’);

$order->send_order_email($insert_id, 2);

if (is_array($order_total_modules->modules))

{

reset($order_total_modules->modules);

while (list(, $value) = each($order_total_modules->modules))

{

$class = substr($value, 0, strrpos($value, ‘.’));

if (!isset($GLOBALS[$class])) continue;

$GLOBALS[$class]->output=null;

}

else

return false;

}

这样后台看到的订单的Payment Shipping 就还是paypal 送货方式.
