Zencart先生成订单后付款，类似淘宝后台修改订单价格，zencart生成订单

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。

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：

<span>function</span> paynow_button(<span>$order_id</span><span>){
    </span><span>if</span> (<span>is_array</span>(<span>$this</span>-><span>modules)) {
      </span><span>if</span> (<span>is_object</span>(<span>$GLOBALS</span>[<span>$this</span>-><span>selected_module])) {
        </span><span>return</span> <span>$GLOBALS</span>[<span>$this</span>->selected_module]->paynow_button(<span>$order_id</span><span>);
      }
    }
}</span>

 

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：

3. 在网站后台 Orders Status（地给你单状态）中，增加一项 Unpaid（未付款）选项。然后修改 Order.php 中 create 方法，指定如果生成订单的时候，客户选择的付款方式是 Paypal，那么此订单的状态将会是 Unpaid状态。代码如下：
