As anyone who has ever used Zen-cart knows, zen-cart the next step is the following (where the representation in [] is not required):
1. Shopping cart (shopping cart)
2. [Shipping Mode (delivery method)]
3. Mode of payment (payment method)
4. Order Confirmation (Confirmation)
5. [Third party web site payments]
6. Order Processing (checkout process)-This step is more important, because the information in the shopping cart will be written to the order
7. Order success (Checkout success)
Such a process does not have any problems under normal circumstances. However, from the 5th step to the 6th part of the process, the user may think that the payment was successful directly off the page, or because of the network cause can not normal jump to the checkout_process page, this result is very serious, because the order can not be normal to create.
Based on the above analysis, we want to slightly change the process, that is, before the payment of the order has been created, so that even if the payment can not be from the Third-party payment site to jump back, we will not have the user payment success in the background without orders. The revised blueprint is basically the following:
1. After Checkour_confirmation page confirmation order, will be directly proccess, and enter the Checkour_success page, can enter the payment page here. As shown in the following illustration:
2. If the customer has not been able to pay, can also enter their own background to the historical order payment. As shown in the following illustration:
Let's take a look at how to achieve the above function in one step.
1. First, we need to make an alteration to the existing payment module. You need to add a field to the class of payment method Paynow_action_url, which represents the URL of the page to be paid, plus a function, Paynow_button ($order _id), to get the parameter hidden field code of the payment form.
To add the Paynow_action_url field, add the following code to the constructor of the class payment:
Copy Code code as follows:
if (Zen_not_null ($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 ($order _id) function, add the following code after the last function of the payment class:
Copy Code code as follows:
function Paynow_button ($order _id) {
if (Is_array ($this->modules)) {
if (Is_object ($GLOBALS [$this->selected_module])) {
return $GLOBALS [$this->selected_module]->paynow_button ($order _id);
}
}
}
2. PayPal payment method as an example of how to achieve the specific. In order not to break the original PayPal code, we will paypal.php file copies of a copy out, and named Paypalsimple.php, and the inside of the code to make appropriate changes. As shown in the code below, you can see that this removes the designation for Form_action_url and gives the paynow_action_url because we want the user to enter checkout_process directly after clicking "Confirm Order", so if you do not specify FORM_ Action_url, then the confirmation order form will be submitted directly to the Checkout_process page, and Paynow_action_url is the previous Form_action_url value. The implementation of the Paynow_button function is also simple, where the contents of the original Process_button () function are simply clipped, except that we do not use the global $order variable, but instead use the $order = New Order ($order _id) To reconstruct an object that is prepared for displaying the pay Now button in a history order.

3. Display the Pay Now button in the Checkout_success page. Open the file "includes/modules/pages/checkout_success/header.php" and add the following code at the end of the file (if you already have the notification/Observer mode in the Zen-cart, And do not want to break the Zen-cart core code, you can also create an observation class to monitor the notify_header_end_checkout_success to achieve.
Copy Code code as follows:
Require_once (dir_ws_classes. ' order.php ');
Require_once (dir_ws_classes. ' payment.php ');
$payment _modules = new Payment ($orders->fields[' Payment_module_code '));
Open the file "includes/modules/templates/template_default/templates/tpl_checkout_success_default.php" and add the following code in the appropriate location, Here is a judge of the status of the order, when only the status of the order in the unpaid status, the button is displayed,
Copy Code code as follows:
<div id= "Pay_now" >
<?php
&& $orders->fields[' orders_status '] = = ' 1 '
if (Isset ($payment _modules->paynow_action_url) && $payment _modules->paynow_action_url!= ' && $orders->fields[' orders_status '] = = ' 1 ') {
Echo (' <fieldset id= "csnotifications" > ");
Echo (' <legend> '. Text_paynow. ' </legend> ');
echo zen_draw_form (' Checkout_paynow ', $payment _modules->paynow_action_url, ' post ', ' id= ' checkout_confirmation ') Onsubmit= "Submitonce ();" "');
$selection = $payment _modules->selection ();
Echo (' <div class= ' buttonrow payment_method ' > '. $selection [0][' module ']. ' </div> ');
Echo (' <div class= "Buttonrow forward Paynow" > ");
if (Is_array ($payment _modules->modules)) {
echo $payment _modules->paynow_button ($orders _id);
}
Echo (Zen_image_submit (Button_image_paynow, Button_image_paynow_alt, ' name= "Btn_paynow" id= "Btn_paynow"));
Echo (' </div> ');
Echo (' </form> ');
Echo (' </fieldset> ');
}
?>
</div>
4. Displays the Pay Now button in the history order. There are three pages that need to display the Pay Now button: Account, Account_history,account_history_info, the implementation here is similar to the Checkout_success page, just to $payment_ Modules function Paynow_button parameter is not the same, here is no longer to repeat.
Summarize:
After the above changes, our process is as follows:
1. Shopping cart (shopping cart)
2. [Shipping Mode (delivery method)]
3. Mode of payment (payment method)
4. Order Confirmation (Confirmation)
5. Order Processing (Checkout process)
6. Order success (Checkout success)
7. [Third party web site payments]
Since the order confirmation to the order processing is done on our own website, and before entering the payment site, the order already exists, so there will be no drop out of the list.
