zen_cart实现支付前生成订单的方法。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
后面添加代码:
| 1 2 3 4 5 6 7 8 9 | // 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'] = $insert_id; | 
为了避免对其他支付方式产生影响,代码做了个判断,只有paypal支付会运行这些生成订单的代码,加了这段后就不用担心会漏单了。
如果需要更完美的做法,为防止顾客在访问checkout process的时候会重复生成订单, 那么就需要加个判断
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | if($_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);$zco_notifier->notify('NOTIFY_CHECKOUT_PROCESS_AFTER_SEND_ORDER_EMAIL');*/} | 
而且在确认页面,如果顾客一直刷新页面,就会一直生成订单,可以加个限制.
| 1 2 3 4 5 6 7 8 9 10 | // create the order record 防漏单if($_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'] = $insert_id;} | 
在pages/checkout_payment/header_php.php任意位置加上
| 1 | unset($_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
| 1 | $_SESSION['order_number_created'] | 
订单不再生成,
如果顾客返回修改了购物车,再次到达checkout_payment时$_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:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 | functionconfirmation() {if(!isset($_SESSION['order_number_created'])){global$order,$order_total_modules,$order_totals,$zco_notifier,$insert_id; $zco_notifier->notify('NOTIFY_CHECKOUT_PROCESS_BEGIN'); // if the customer is not logged on, redirect them to the time out pageif(!$_SESSION['customer_id']) { zen_redirect(zen_href_link(FILENAME_TIME_OUT)); } else{ // validate customer { $_SESSION['navigation']->set_snapshot(array('mode'=> 'SSL', 'page'=> FILENAME_CHECKOUT_SHIPPING));zen_redirect(zen_href_link(FILENAME_LOGIN, '', 'SSL')); } } if(isset($mycartID)&&$mycartID== $_SESSION['cart']->cartID){ returnarray('title'=> MODULE_PAYMENT_PAYPAL_TEXT_DESCRIPTION); } $mycartID= $_SESSION['cart']->cartID; $order= neworder; // prevent 0-entry orders from being generated/spoofed if(sizeof($order->products) < 1) { zen_redirect(zen_href_link(FILENAME_SHOPPING_CART)); } $order_total_modules= neworder_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;}}}elsereturnfalse;} |
