zencart針對除了paypal之外. 客戶通過其他的支付方式進入index.php?main_page=checkout_confirmation這個頁面就能生出訂單.paypal就有點與眾不同, 它只能是從它的官網 [paypal.com] 返回來并且進入checkout_process這個頁面后,才能生出訂單,而意外常會發生:比如網絡不順. 又比如客戶不小心在返回前就關了頁面.
paypal防漏單的原理就是——在 checkout_confirmation.php這個頁面先生出訂單!!!最模板提供解決方法
方法是：在這個文件的最后部分echo TITLE_CONTINUE_CHECKOUT_PROCEDURE . ‘<br />’ . TEXT_CONTINUE_CHECKOUT_PROCEDURE;
后面添加代碼：
// create the order record 防漏單
if ($_SESSION['payment'] == ‘paypal’) {
$insert_id = $order->create($order_totals, 2);
$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_ORDER_CREATE’);
$payment_modules->after_order_create($insert_id);
$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_PAYMENT_MODULES_AFTER_ORDER_CREATE’);
// store the product info to the order
$order->create_add_products($insert_id);
$_SESSION['order_number_created'] = $insert_id;
為了避免對其他支付方式產生影響，代碼做了個判斷，只有paypal支付會運行這些生成訂單的代碼，加了這段后就不用擔心會漏單了—成功付款后后臺訂單如圖：
其中GS/AK的為防漏單的訂單，只有在出現漏單的時候才會查看這些訂單，里面的信息跟正常訂單相比會少一個交易號，但是至少是可以看到客戶信息及所購買了什么產品…
如果需要更完美的做法, 為防止顧客在訪問checkout process的時候會重復生成訂單, 那么就需要加個判斷
if($_SESSION['payment']!=’paypal’){
/*// create the order record
$insert_id = $order->create($order_totals, 2);
$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_ORDER_CREATE’);
$payment_modules->after_order_create($insert_id);
$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_PAYMENT_MODULES_AFTER_ORDER_CREATE’);
// 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’);
//send email notifications
$order->send_order_email($insert_id, 2);
$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_SEND_ORDER_EMAIL’);*/
}
而且在確認頁面，如果顧客一直刷新頁面，就會一直生成訂單，可以加個限制.
// create the order record 防漏單
if ($_SESSION['payment'] == ‘paypal’ and !isset($_SESSION['order_number_created'])) {
$insert_id = $order->create($order_totals, 2);
$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_ORDER_CREATE’);
$payment_modules->after_order_create($insert_id);
$zco_notifier->notify(‘NOTIFY_CHECKOUT_PROCESS_AFTER_PAYMENT_MODULES_AFTER_ORDER_CREATE’);
// store the product info to the order
$order->create_add_products($insert_id);
$_SESSION['order_number_created'] = $insert_id;
}
在pages/checkout_payment/header_php.php任意位置加上unset($_SESSION['order_number_created']);
這樣,就算顧客在確認頁面一直刷新，因為已經設置了$_SESSION['order_number_created']，訂單不再生成，如果顧客返回修改了購物車，再次到達checkout_payment時$_SESSION['order_number_created']將被清除，
其實，生成訂單的代碼可以寫在modules/payment/paypal.php的 function confirmation()中。
代碼如下：
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;
}
這樣后臺看到的訂單 的Payment Shipping 就還是paypal 送貨方式.
