Zencart 使用 Paypal 付款，会出现漏单的情况，即 paypal 已经收到客户的付款，但是网站后台没有客户的订单。导致 paypal 漏单的原因大致会是当客户跳转到Paypal 网站付款完毕之后，直接关闭了窗口，或者网络不稳定，没有正常跳转到网站。
解决 Paypal 漏单问题的方案有好几种：
一. 开启 Detailed Line Items in Cart 选项。
原理：在 zencart 后台 Module --> Payment --> PayPal Website Payments Standard - IPN 开启 Detailed Line Items in Cart 选项。这个选项会把你所有的订单物品信息传给 paypal，当客户付款成功而后台未能成功生成订单时，也可以通过 paypal 帐号交易信息看到客户购买了哪些物品。
二. 使用 Paypal Sessions Viewer 插件找回 Paypal 漏掉的订单。
原理：zencart 购物车的物品，通过 paypal 方式付款，会在 paypal_session 表中保存此次付款的所有记录，如果付款成功后，从 paypal 网站跳转到购物网站并生成了订单时，zencart系统会自动删除这条 paypal_session 记录，如果没有成功跳转到购物网站，没有成功生成订单，那这条付款记录数据就会一直保存在数据库，当使用 Paypal Session Viewer 插件，就能查看这条记录的所有数据，包括客户信息，购物时间，商品信息，如果你确定已收到款，就可以把这条 paypal_session 信息转移到订单中，生成一个订单。

三. 修改付款流程，先生成订单后付款。
原理：用过zen-cart的人都知道，zen-cart中下单步骤是下面这样的(其中[]中的表示不是必须的)：
1. 购物车(shopping cart)
2. [货运方式(delivery method)]
3. 支付方式(payment method)
4. 订单确认(confirmation)
5. [第三方网站支付]
6. 订单处理(checkout process)——这一步比较重要，因为会在这里将购物车中的信息写入订单
7. 下单成功(checkout success)
这样的流程在正常情况下是没有任何问题的。但是，从第5步到第6部的过程中，用户可能以为付款成功就直接关闭掉网页了，或者由于网络原因造成不能正常跳转到checkout_process页面，这样造成的后果是很严重的，因为订单不能被正常的创建。基于上述的分析， 我们希望稍微地改变一下流程，即在支付之前订单已经创建好了，这样就算在支付时不能从第三方支付网站跳转回来，我们也不会存在用户付款成功却在后台没有订单的情况了。
本人是参照东国先生的这篇 修改zen-cart下单和付款流程以防止漏单 教程去修改的，因为这个教程比较老，而且也没有很全面，所以我根据自己的实际需求，把他做的更完善，更细节化。
经过修改后的蓝图基本是下面这样的：
1. 在checkour_confirmation页面确认订单后，都会直接proccess，并且进入 account_history_info 页面,可以在这里进入付款页面。如下图所示：
2. 如果当时客户没能付款，也可进入自己的后台对历史订单进行付款。如下图所示：
3. 未付款的订单，可以在后台修改价格，像淘宝一样拍下宝贝后，店主给你修改价格后再付款一样。如下图所示：
下面我们来正式修改代码，首先我列举出所有要修改的文件：
1. includes/classes/payment.php
2. includes/modules/payment/paypal.php
3. includes/classes/order.php
4. includes/modules/pages/checkout_process/header_php.php
5. includes/modules/pages/account_history_info/header_php.php
6. includes/templates/你的模板目录/templates/tpl_account_history_info_default.php
7. includes/templates/你的模板目录/templates/tpl_account_history_default.php
8. ipn_main_handler.php
9. admin(后台目录)/orders.php
因为先生成订单再付款，付款步骤就会比原来又多了一步，为了简化付款流程，我安装了 Fast And Easy Checkout For Zencart(快速支付) 插件，安装此插件之前，需要安装另外一个插件 Css Js Loader For Zencart，这是快速支付插件的依赖插件。快速支付与先生成订单后支付没什么因果关系，所以如果你不想安装的话完全可以不理。
按步骤修改上面列举的文件：
1. 首先我们需要对现有的支付模块进行一个改造。需要对支付方式的class增加一个字段paynow_action_url，用来表示进行支付的页面 url，另外还需要增加一个函数，paynow_button($order_id)，来获取支付表单的参数隐藏域代码。
要增加 paynow_action_url 变量，请在类payment的构造函数中最后加上下面的代码：
if ( (zen_not_null($module)) && (in_array($module.'.php', $this->modules)) && (isset($GLOBALS[$module]->paynow_action_url)) ) { $this->paynow_action_url = $GLOBALS[$module]->paynow_action_url; }
要增加paynow_button($order_id)函数，请在payment类的最后一个函数之后加上如下的代码：
function paynow_button($order_id){ if (is_array($this->modules)) { if (is_object($GLOBALS[$this->selected_module])) { return$GLOBALS[$this->selected_module]->paynow_button($order_id); } } }
2. 以paypal支付方式为例子，说明如何具体实现。这里直接修改 paypal.php 文件，注意备份此文件。代码如下所示，可以看到，这里去掉了对 form_action_url 的指定，并给定了 paynow_action_url，因为我们希望用户点击“确认订单”后直接进入checkout_process，所以如果不指定 form_action_url，那么确认订单的表单就会直接提交到 checkout_process 页面了，而 paynow_action_url 就是 以前的 form_action_url 的值。paynow_button 函数的实现也很简单，这里只是将原先的 process_button() 函数的内容剪切过来而已，只不过我们没有使用全局的$order变量，而是使用 $order = new order($order_id),来重新构造的一个对象，这样做是为在历史订单中显示pay now按钮做准备的。paypal.php修改后的文件如下：
