zen_cart实现支付前生成订单的方法,zen_cart生成订单
本文实例讲述了zen_cart实现支付前生成订单的方法。分享给大家供大家参考,具体如下:
除了paypal之外. 客户通过其他的支付方式进入index.php?main_page=checkout_confirmation这个页面就能生出订单.
但是!! paypal就有点与众不同, 它只能是从它的官网 [paypal.com] 返回来并且进入checkout_process这个页面后,才能生出订单
而意外常会发生:比如网络不顺. 又比如客户不小心在返回前就关了页面.
那么,我们的网站后台就看不到客户买的是什么产品(虽然在paypal后台能看到是谁买了,但确实是无法知道他到底买了什么,)这可是一个好郁闷的事情
paypal防漏单的原理就是------在 checkout_confirmation.php这个页面先生出订单!!!
方法是:在这个文件的最后部分
复制代码 代码如下:echo TITLE_CONTINUE_CHECKOUT_PROCEDURE . '
' . TEXT_CONTINUE_CHECKOUT_PROCEDURE;
后面添加代码:
// create the order record 防漏单 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'] = $insert_id;
为了避免对其他支付方式产生影响,代码做了个判断,只有paypal支付会运行这些生成订单的代码,加了这段后就不用担心会漏单了。
如果需要更完美的做法,为防止顾客在访问checkout process的时候会重复生成订单, 那么就需要加个判断
if($_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); $zco_notifier->notify('NOTIFY_CHECKOUT_PROCESS_AFTER_SEND_ORDER_EMAIL');*/ }
而且在确认页面,如果顾客一直刷新页面,就会一直生成订单,可以加个限制.
// create the order record 防漏单 if ($_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']);
这样,就算顾客在确认页面一直刷新,因为已经设置了
$_SESSION['order_number_created']
订单不再生成,
如果顾客返回修改了购物车,再次到达checkout_payment时$_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; }
