Introduction

Redirecting the checkout complete page in Drupal Commerce can be a complex task, especially when you have custom modules and payment gateways involved. In this article, we will guide you through the process of redirecting the checkout complete page in Drupal Commerce, with a focus on custom modules and payment gateways.

Understanding the Checkout Process in Drupal Commerce

Before we dive into the redirection process, it's essential to understand the checkout process in Drupal Commerce. The checkout process typically involves the following steps:

  1. Review Order: The user reviews their order and selects a payment method.
  2. Payment Gateway: The user is redirected to the payment gateway to complete the payment.
  3. Checkout Complete: The user is redirected to the checkout complete page after completing the payment.

Custom Module and Payment Gateway Integration

In your case, you have a custom module that redirects to a local payment API after the user selects the local payment gateway in the review order page. The users enter their username and password in the local payment API to complete the payment. After completing the payment, you want to redirect the user to a specific page.

Redirecting the Checkout Complete Page

To redirect the checkout complete page in Drupal Commerce, you can use the hook_cart_alter hook in your custom module. This hook allows you to alter the cart object before it is saved.

Step 1: Implement the hook_cart_alter hook

In your custom module, implement the hook_cart_alter hook to alter the cart object before it is saved. This hook will allow you to redirect the checkout complete page.

function your_module_cart_alter(&$cart) {
  // Get the current order
  $order = commerce_order_load($cart->order_id);

// Check if the order has been paid
if ($order->payment_status == 'paid') {
// Redirect the user to the checkout complete page
drupal_goto('checkout-complete');
}
}

Step 2: Create a custom route for the checkout complete page

Create a custom route for the checkout complete page in your custom module. This route will handle the redirect to the checkout complete page.

function your_module_menu() {
  $items['checkout-complete'] = array(
    'title' => 'Checkout Complete',
    'page callback' => 'your_module_checkout_complete',
    'access arguments' => array('access checkout complete'),
  );
  return $items;
}

function your_module_checkout_complete() {
// Render the checkout complete page
return theme('checkout_complete');
}

Step 3: Implement the checkout_complete theme function

Implement the checkout_complete theme function to render the checkout complete page.

function theme_checkout_complete() {
  // Render the checkout complete page
  return '<h1>Checkout Complete</h1>';
}

Conclusion

Redirecting the checkout complete page in Drupal Commerce can be a complex task, but with the right approach, it can be achieved. By implementing the hook_cart_alter hook, creating a custom route for the checkout complete page, and implementing the checkout_complete theme function, you can redirect the checkout complete page in Drupal Commerce.

Additional Tips and Considerations

  • Make sure to test your custom module thoroughly to ensure that it works as expected.
  • Consider using a more robust payment gateway that supports redirecting to a custom page after payment completion.
  • If you have multiple payment gateways, consider creating a separate custom module for each gateway to avoid conflicts.
