Zencart creates an order and then pays. It is similar to modifying the order price in the Taobao backend. Zencart generates an order_PHP tutorial

Zencart generates an order and then pays, similar to Taobao backend to modify the order price, zencart generates the order

Zencart uses Paypal to pay, there will be missed orders, that is, paypal has received the customer payment, but there is no order from the customer in the website backend. The main reason for missing orders in Paypal is that when the customer jumps to the Paypal website and completes the payment, he directly closes the window, or the network is unstable and does not jump to the website normally.

There are several solutions to solve the problem of missed orders in Paypal:

1. Turn on the Detailed Line Items in Cart option.

Principle: Open the Detailed Line Items in Cart option in the zencart backend Module --> Payment --> PayPal Website Payments Standard - IPN. This option will transfer all your order item information to PayPal. When the customer pays successfully but the backend fails to successfully generate the order, you can also see which items the customer purchased through the PayPal account transaction information.

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; }

To add the paynow_button($order_id) function, please add the following code after the last function of the payment class:

<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. Take the paypal payment method as an example to explain how to implement it. Modify the paypal.php file directly here, and be sure to back up this file. The code is as shown below. You can see that the specification of form_action_url is removed here and paynow_action_url is given. Because we hope that the user will directly enter the checkout_process after clicking "Confirm Order", so if form_action_url is not specified, then the form to confirm the order will be It is submitted directly to the checkout_process page, and paynow_action_url is the value of the previous form_action_url. The implementation of the paynow_button function is also very simple. Here we just cut the content of the original process_button() function, but we do not use the global $order variable, but use $order = new order($order_id) to re- An object constructed in preparation for displaying the pay now button in historical orders. The modified file of paypal.php is as follows:

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：
