WooCommerce is an adaptable e-commerce platform that provides a wide array of features through which you can talk to your store. However, there are certain cases where you may want to restrict payment gateways, provided the products are in your customer’s cart. It might be a scenario where you want to disable “Cash on Delivery” for high-value items or restrict “Bank Transfer” for specific products. Let me guide you through the process of disabling payment gateways for distinct products all in WooCommerce subject matter.

Why Disable Payment Gateways for Specific Products?

Limiting payment gateways for certain products can enhance your store’s performance and customer satisfaction by:

• Preventing unsuitable payment options for particular items.
• Maintaining adherence to specific business policies or regulations.
• Simplifying the checkout process to minimize cart abandonment.

Now, let’s explore how you can achieve this using a custom code snippet.

Steps to Disable Payment Gateways for Specific Products

1. Identify Product and Payment Gateway IDs

Before adding the code, you need to identify:

• Product IDs: Go to your WordPress dashboard, navigate to Products > All Products, and hover over a product name. You’ll see the product ID displayed below the title.
• Payment Gateway IDs: Navigate to WooCommerce > Settings > Payments, and click on the payment method. Check the URL in your browser; the ID appears after section=. For example, section=paypal indicates the PayPal gateway.

2. Add the Custom Code

Here is the PHP code to disable specific payment gateways based on the product IDs in the cart:

add_filter('woocommerce_available_payment_gateways', 'restrict_payment_gateways_for_specific_products');

function restrict_payment_gateways_for_specific_products($available_gateways) {
    // Ensure this runs only on the checkout page and not in the admin area
    if (!is_checkout() || is_admin()) {
        return $available_gateways;
    }

    // Array of product IDs to restrict payment gateways for
    $restricted_products = array(87, 88);

    // Array of payment gateway IDs to restrict
    $restricted_gateways = array('cod', 'paypal');

    // Check if the cart contains any of the restricted products
    $cart_contains_restricted_product = false;

    foreach (WC()->cart->get_cart() as $cart_item) {
        if (in_array($cart_item['product_id'], $restricted_products, true)) {
            $cart_contains_restricted_product = true;
            break;
        }
    }

    // If restricted products are found, remove the specified gateways
    if ($cart_contains_restricted_product) {
        foreach ($restricted_gateways as $gateway_id) {
            if (isset($available_gateways[$gateway_id])) {
                unset($available_gateways[$gateway_id]);
            }
        }
    }

    return $available_gateways;
}

3. How the Code Works

• Cart Check: The function loops through all items in the cart to see if any restricted product IDs are present.
• Payment Gateway Restriction: If a restricted product is found, the specified payment gateways are removed from the available options during checkout.

4. Add the Code to Your Website

To implement this code:

• Open your WordPress dashboard.
• Navigate to Appearance > Theme File Editor.
• Open your theme’s functions.php file.
• Paste the code at the bottom and save the file.

Alternatively, use the Code Snippets plugin to add the code without modifying theme files.

5. Test the Functionality

After adding the code:

1. Add a restricted product to the cart.
2. Proceed to the checkout page.
3. Verify that the specified payment gateways (e.g., COD or Bank Transfer) are no longer visible.
4. Test with non-restricted products to ensure other gateways are unaffected.

Extending the Code to Categories

If you also want to restrict payment gateways by product category, you can extend the code to check for categories. Replace the relevant portion of the cart check with the following:

add_filter('woocommerce_available_payment_gateways', 'restrict_payment_gateways_by_product_id_and_category');

function restrict_payment_gateways_by_product_id_and_category($available_gateways) {
    // Ensure this runs only on the checkout page and not in the admin area
    if (!is_checkout() || is_admin()) {
        return $available_gateways;
    }

    // Array of product IDs to restrict payment gateways for
    $restricted_products = array(339, 369, 368, 367); // Replace with your product IDs

    // Array of product categories to restrict payment gateways for
    $restricted_categories = array('restricted-category', 'special-category'); // Replace with your category slugs

    // Array of payment gateway IDs to restrict
    $restricted_gateways = array('cod', 'bacs'); // Replace with your gateway IDs

    // Check if the cart contains any restricted product or product from restricted categories
    $cart_contains_restricted_item = false;

    foreach (WC()->cart->get_cart() as $cart_item) {
        // Check by Product ID
        if (in_array($cart_item['product_id'], $restricted_products, true)) {
            $cart_contains_restricted_item = true;
            break;
        }

        // Check by Product Category
        $product_categories = wc_get_product_term_ids($cart_item['product_id'], 'product_cat');
        foreach ($product_categories as $category_id) {
            $category = get_term($category_id, 'product_cat');
            if (in_array($category->slug, $restricted_categories, true)) {
                $cart_contains_restricted_item = true;
                break 2; // Break out of both loops
            }
        }
    }

    // If restricted items are found in the cart, remove the specified gateways
    if ($cart_contains_restricted_item) {
        foreach ($restricted_gateways as $gateway_id) {
            if (isset($available_gateways[$gateway_id])) {
                unset($available_gateways[$gateway_id]);
            }
        }
    }

    return $available_gateways;
}
