Zencart pays after placing an order, similar to Taobao backend where you can modify the order price.

gt lt order

When Zencart uses Paypal for payment, there will be missed orders, that is, Paypal has received the customer's 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's payment is successful but the backend fails to successfully generate the order, you can also see which items the customer purchased through the PayPal account transaction information.

2. Use the Paypal Sessions Viewer plug-in to retrieve orders missed by Paypal.

Principle: If the items in the zencart shopping cart are paid through paypal, all records of the payment will be saved in the paypal_session table. If the payment is successful and the order is jumped from the paypal website to the shopping website and an order is generated, the zencart system will Automatically delete this paypal_session record. If you do not successfully jump to the shopping website and do not successfully generate an order, then this payment record data will always be saved in the database. When you use the Paypal Session Viewer plug-in, you can view all the data of this record. , including customer information, shopping time, and product information. If you are sure that payment has been received, you can transfer this paypal_session information to the order and generate an order.

3. Modify the payment process, first place the order and then pay.

Principle: Anyone who has used zen-cart knows that the ordering steps in zen-cart are as follows (the expressions in [] are not necessary):

1. Shopping cart

2 . [delivery method]

3. payment method

4. order confirmation (confirmation)

5. [third-party website payment]

6. order processing (checkout process)—— This step is important, because the information in the shopping cart will be written into the order here

7. Order successful (checkout success)

There is no problem with this process under normal circumstances. However, in the process from step 5 to step 6, the user may think that the payment is successful and close the web page directly, or the user may not be able to jump to the checkout_process page normally due to network reasons. The consequences of this are very serious, because the order Cannot be created normally. Based on the above analysis, we hope to change the process slightly, that is, the order has been created before payment, so that even if the payment cannot be jumped back from the third-party payment website, we will not have the user pay successfully but there will be no error in the background. Order status.

I followed Mr. Dongguo’s tutorial on modifying the zen-cart ordering and payment process to prevent missed orders. Because this tutorial is relatively old and not very comprehensive, I modified it based on my actual needs. He made it more perfect and detailed.

The modified blueprint is basically as follows:

1. After confirming the order on the checkour_confirmation page, you will directly proccess and enter the account_history_info page, where you can enter the payment page. As shown in the picture below:

2. If the customer fails to pay at that time, they can also enter their own backend to pay for historical orders. As shown in the picture below:

3. For unpaid orders, you can modify the price in the background. Just like Taobao, after taking a photo of the product, the store owner will modify the price for you before paying. As shown in the figure below:

Let’s formally modify the code. First, I list all the files to be modified:

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/ Your template directory/templates/tpl_account_history_info_default.php

7. includes/templates/Your template directory/templates/tpl_account_history_default.php

8. ipn_main_handler.php

9. admin (backend directory)/orders.php

Because you create an order first and then pay, the payment step will be one more step than before. In order to simplify the payment process, I installed the Fast And Easy Checkout For Zencart (fast payment) plug-in. Before installing this plug-in, you need to install another plug-in Css Js Loader For Zencart, which is a dependent plug-in of the fast payment plug-in. There is no causal relationship between quick payment and payment after placing an order, so you can ignore it if you don’t want to install it.

Follow the steps to modify the files listed above:

1. First we need to transform the existing payment module. You need to add a field paynow_action_url to the payment method class to represent the page url for payment. In addition, you need to add a function, paynow_button($order_id), to obtain the parameter hidden field code of the payment form.

To add the paynow_action_url variable, please add the following code at the end of the constructor of the payment class:

<span>if</span> ( (zen_not_null(<span>$module</span>)) &amp;&amp; (<span>in_array</span>(<span>$module</span>.'.php', <span>$this</span>-&gt;modules)) &amp;&amp; (<span>isset</span>(<span>$GLOBALS</span>[<span>$module</span>]-&gt;<span>paynow_action_url)) ) {
        </span><span>$this</span>-&gt;paynow_action_url = <span>$GLOBALS</span>[<span>$module</span>]-&gt;<span>paynow_action_url;        
}</span>

Copy after login

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

Copy after login

2. Take the paypal payment method as an example to explain how to implement it. Modify the paypal.php file directly here, 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 contents of the original process_button() function, but instead of using the global $order variable, we 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:
