WooCommerce Custom Flat Rate Shipping Based on Product Quantity and Free Shipping Conditions

WooCommerce Custom Flat Rate Shipping Based on Product Quantity and Free Shipping

When you want more control over shipping rates in WooCommerce, the default options often fall short. In this guide, we’ll walk you through a custom solution that automatically increases the shipping cost based on the number of products in the cart and hides flat rate shipping when free shipping is available.

This solution is perfect if you:

• Want to charge extra shipping fees per product.

• Want to hide flat rate shipping when customers qualify for free shipping.

Let’s dive in! 🚀

🎯 What We’re Building

• If the cart has only one product, apply the default flat rate.

• If the cart has more than one product, add $3 per additional product (excluding the first).

• If free shipping is available, hide flat rate shipping entirely.

✅ Full WooCommerce Shipping Customization Code

Add the following code to your theme’s functions.php file or a custom plugin:

add_filter('woocommerce_package_rates', 'custom_flat_rate_shipping_with_extra_per_product', 10, 2);

function custom_flat_rate_shipping_with_extra_per_product($rates, $package) {
    // Get total quantity of products in the cart
    $cart_item_count = WC()->cart->get_cart_contents_count();

    // Flag to check if free shipping is available
    $free_shipping_available = false;

    // Check if free shipping is present in the rates
    foreach ($rates as $rate) {
        if (strpos($rate->method_id, 'free_shipping') !== false) {
            $free_shipping_available = true;
            break;
        }
    }

    foreach ($rates as $rate_key => $rate) {
        // Check if this is the flat rate shipping method
        if (strpos($rate->method_id, 'flat_rate') !== false) {

            // If free shipping is available, remove flat rate option
            if ($free_shipping_available) {
                unset($rates[$rate_key]);
                continue; // Skip further processing
            }

            // If more than one product, add extra cost
            if ($cart_item_count > 1) {
                // Add $3 for each additional product (excluding the first)
                $additional_cost = ($cart_item_count - 1) * 3;

                // Update the shipping cost
                $rates[$rate_key]->cost += $additional_cost;

                // Optional: Update taxes if necessary
                if (!empty($rates[$rate_key]->taxes)) {
                    foreach ($rates[$rate_key]->taxes as $tax_id => $tax_amount) {
                        $additional_tax = ($additional_cost) * ($tax_amount / $rate->cost);
                        $rates[$rate_key]->taxes[$tax_id] += $additional_tax;
                    }
                }
            }
        }
    }

    return $rates;
}

🔧 Explanation:

• Flat Rate Detection: The code checks if the shipping method is a flat rate.

• Free Shipping Check: If free shipping is available, the flat rate option is automatically hidden.

• Dynamic Pricing: Adds $3 for each additional product in the cart beyond the first.

🚀 Why This is Useful:

• Keeps your shipping pricing flexible and competitive.

• Encourages larger orders by offering clear shipping cost logic.

• Improves user experience by automatically hiding unnecessary options.

📚 Final Thoughts:

WooCommerce is powerful, but with a bit of custom code, you can take your store to the next level. This shipping customization is an excellent example of how to fine-tune the shopping experience to match your store’s policies and pricing structure.

How to Show Shipping Methods in WooCommerce Based on Country and Cart Subtotal

Introduction

If you’re running an online store with WooCommerce, you may want to customize your shipping options based on country and cart subtotal. For example, you might want to always show shipping options for the US and Canada, but for all other countries, only display shipping if the cart subtotal is $200 or more.

In this guide, we’ll show you exactly how to achieve this using a simple WooCommerce hook.

What You’ll Learn:

• How to target specific countries for shipping rules.

• How to set a minimum cart subtotal for showing shipping options.

• How to add custom PHP code to your WordPress theme.

Step 1: Open Your Theme’s Functions File

To begin, go to your WordPress dashboard:

1. Navigate to Appearance > Theme File Editor.

2. Open the file called functions.php (Make sure you are editing a child theme to avoid losing changes after updates).

Step 2: Add This Custom PHP Snippet

Here’s the code you need to paste inside your functions.php file:

add_filter('woocommerce_package_rates', 'custom_shipping_method_based_on_country_and_subtotal', 10, 2);

function custom_shipping_method_based_on_country_and_subtotal($rates, $package) {
    // Get the shipping country
    $shipping_country = $package['destination']['country'];

    // Get the cart subtotal (excluding taxes and shipping)
    $cart_subtotal = WC()->cart->subtotal;

    // If country is US or CA, allow shipping methods as normal
    if ($shipping_country === 'US' || $shipping_country === 'CA') {
        return $rates;
    }

    // For all other countries, only show shipping methods if subtotal is >= 200
    if ($cart_subtotal >= 200) {
        return $rates; // Allow shipping methods
    } else {
        // Hide all shipping methods
        return [];
    }
}

How the Code Works:

• It checks the shipping destination country.

• If the country is US or Canada, it allows all shipping methods as usual.

• If the country is any other country, it checks if the cart subtotal is at least $200.

• If not, all shipping options are hidden.

✅ Step 3: Save and Test

• Save the changes in your functions.php file.

• Test your cart:

  • Select the US or Canada – shipping should always appear.

  • Select any other country – shipping should only appear if the cart subtotal is $200 or more.

Pro Tip: Make It a Custom Plugin

If you don’t want to lose this code when your theme updates, consider wrapping it into a simple custom plugin. You can create a new .php file, add plugin headers, and paste the same function inside.

How I Use APIs to Build Smarter, Faster Apps — A Solo Dev’s Perspective from Codrammer.com

Hi, I’m the developer behind Codrammer.com, and as a solo coder, APIs are my secret weapon for building powerful applications without reinventing the wheel.

Whether you’re flying solo like me or part of a team, understanding how to effectively use APIs can save you tons of time and headaches.

What’s an API and Why Should You Care?

Simply put, an API (Application Programming Interface) lets your app talk to other apps or services. Instead of building every feature from scratch, you tap into existing tools — like payment gateways, user authentication, data providers, and more.

For example, when you buy something online, chances are an API helped process your payment behind the scenes.

How APIs Help Me as a Solo Developer

Being a one-person team means I wear many hats — frontend, backend, DevOps, and more. APIs help me by:

• Speeding up development: I can integrate complex features fast, like sending emails, processing payments, or running background checks, just by calling an API.

• Keeping my codebase lean: No need to build bulky systems. APIs do the heavy lifting.

• Focusing on core features: I spend more time improving my app’s unique value instead of rebuilding common functionality.

• Learning on the fly: Each API teaches me new best practices and tools.

My Tips for Working With APIs

1. Start with good docs: I always read the API documentation thoroughly before coding. It saves so much trial and error.

2. Secure your keys: Never expose API keys in public code. I keep mine in environment variables.

3. Handle errors: APIs can fail or rate-limit you. I build in retries and graceful error messages.

4. Test with tools: Before writing code, I use Postman or curl to play with API calls.

5. Automate with scripts: I write small scripts or Laravel jobs to interact with APIs asynchronously when possible.

Real Example: Background Check Integration

One project required me to add background checks to user onboarding. Instead of building a whole screening system, I plugged into a third-party API.

• I send applicant data to create an order.

• Poll the order status to track progress.

• Fetch reports in PDF format.

• Even cancel orders if needed.

This API integration saved me weeks of development and gave users a professional, trustworthy experience.

Final Thoughts

As a solo developer, APIs are game changers. They help me move fast, keep things simple, and build apps that can scale when needed.

If you’re coding solo too, I highly recommend mastering API integrations. They’re a force multiplier that every modern developer should harness.
