How to Create a Custom Payment Method in PrestaShop: A Step-by-Step Guide

PrestaShop is a powerful, flexible e-commerce platform that allows you to build and manage an online store with ease. One of its most significant features is the ability to customize and extend the functionality of your store. A key area where you can make improvements is the payment process. PrestaShop supports various payment gateways, but sometimes, you may need to implement a custom payment method that suits your specific business needs. Whether you want to offer a unique payment option or integrate a local payment gateway, creating a PrestaShop custom payment method is a great way to enhance your store's flexibility.

In this guide, we will walk you through the process of creating a custom payment method in PrestaShop, from setting it up to testing it. Let’s dive in!

Step 1: Understand the Basics of PrestaShop Custom Payment Method

Before we start, it’s essential to understand the concept of a PrestaShop custom payment method. In PrestaShop, payment methods are what your customers use to pay for their orders. These methods can include traditional options like PayPal or credit card payments, but you might also want to offer a custom solution such as bank transfers, cash on delivery, or any other specific payment method.

A custom payment method can be beneficial for several reasons:

• Local Payment Methods: Offer payment solutions tailored to specific regions or countries.
• Business-Specific Methods: Integrate with your business’s internal payment processes.
• Enhanced Flexibility: Provide customers with more choices during checkout.

Step 2: Create a Module for Your Custom Payment Method

PrestaShop operates on a module-based architecture, meaning that custom features like payment methods are added via modules. To create a PrestaShop custom payment method, you will first need to create a module that will contain the necessary code to handle your custom payment logic.

1. Go to the PrestaShop modules folder on your server.

   • Navigate to your PrestaShop root directory and find the modules folder.
   • Create a new folder for your custom payment method module. For example, name it custompayment.

2. Create the main PHP file for your module.

   • Inside your custompayment folder, create a PHP file. You can name it custompayment.php.
   • This file will define the structure of your module and handle the logic for the custom payment method.

   Example of a basic module structure:

   php

   Copy code

   <?php if (!defined('_PS_VERSION_')) { exit; } class CustomPayment extends PaymentModule { public function __construct() { $this->name = 'custompayment'; $this->tab = 'payments_gateways'; $this->version = '1.0.0'; $this->author = 'Your Name'; $this->need_instance = 0; parent::__construct(); $this->displayName = $this->l('Custom Payment Method'); $this->description = $this->l('A custom payment method for your PrestaShop store.'); } public function install() { if (!parent::install() || !$this->registerHook('payment')) { return false; } return true; } public function hookPayment($params) { $this->context->smarty->assign( array( 'payment_option' => 'Custom Payment Option', ) ); return $this->display(__FILE__, 'payment.tpl'); } }

   This code defines the module's structure, including its name, description, and installation process. It also registers a hook to display the payment method during the checkout process.

Step 3: Create the Payment Form

After setting up the module, you need to create a payment form that will be displayed during the checkout process. This is where customers will choose your custom payment method.

1. Create the payment.tpl template file.

   • Inside the custompayment folder, create a views/templates/hook directory and add a payment.tpl file.
   • This template will define how the payment option will appear to the customers.

   Example payment.tpl file:

   html

   Copy code

   <form action="{$url}" method="post"> <p><strong>Custom Payment Method</strong></p> <label for="custom_payment">Select Your Payment Option:</label> <select name="custom_payment" id="custom_payment"> <option value="bank_transfer">Bank Transfer</option> <option value="cash_on_delivery">Cash on Delivery</option> </select> <input type="submit" value="Confirm Payment" /> </form>

   This simple form gives customers two options—bank transfer or cash on delivery—and allows them to select their preferred payment method.

Step 4: Handle Payment Confirmation

Once the customer selects their payment option and submits the form, you need to process the payment and confirm the order. In your custom payment method, you’ll want to handle the confirmation process.

1. Create a method to confirm the payment in the custompayment.php file.

   php

   Copy code

   public function confirmPayment($params) { $selected_payment = Tools::getValue('custom_payment'); if ($selected_payment === 'bank_transfer') { // Process bank transfer payment // Code to handle bank transfer logic here } elseif ($selected_payment === 'cash_on_delivery') { // Process cash on delivery // Code to handle cash on delivery logic here } }

   This method checks which payment option the customer selected and processes the payment accordingly.

Step 5: Test Your Custom Payment Method

Now that you’ve set up your PrestaShop custom payment method, it’s essential to test it to make sure everything is working correctly.

1. Enable the module in the PrestaShop back office by going to Modules > Module Manager and finding your custom payment method.
2. Test the checkout process to ensure the custom payment method appears and functions as expected.
3. Perform test transactions for each payment option (e.g., bank transfer and cash on delivery) to confirm the logic is correct.

Step 6: Finalizing and Going Live

Once you’ve tested everything and confirmed the custom payment method works as expected, you can make it live for your customers. Ensure that you monitor the payment process and address any potential issues that might arise.
