[Christopher]

Hey! Could anyone provide a detailed explanation of the various methods and best practices for programmatically adding a fee to an order in WooCommerce?

Specifically, I am interested in understanding the necessary hooks, functions, and code snippets involved in this process, as well as any potential implications for order calculations, tax settings, and customer notifications.

Here is How You Can Set Woocommerce Additional Fees on Checkout

Adding fees to WooCommerce orders programmatically can enhance your store’s functionality, allowing for dynamic pricing adjustments based on various conditions.

Below I have explained how to achieve this, including necessary hooks, functions, and best practices.

1. Understanding the Basics
In WooCommerce, you can add fees to an order using the woocommerce_cart_calculate_fees action hook. This hook allows you to modify the cart’s total before it is processed for checkout.

2. Code Snippet for Adding Fees
Here’s a basic example of how to add a fee programmatically:

Code:

add_action(‘woocommerce_cart_calculate_fees’, ‘add_custom_fee’);
function add_custom_fee() {
// Check if the cart total meets a specific condition
if (WC()->cart->subtotal >= 100) { // Example condition: subtotal >= $100
$fee = 10; // Amount of the fee
WC()->cart->add_fee(__(‘Custom Fee’, ‘your-text-domain’), $fee);
}
}

3. Explanation of the Code

• Hook: woocommerce_cart_calculate_fees is triggered when the cart is recalculated.
• Function: add_custom_fee() is a custom function where you define your fee logic.
• Condition: In this example, a fee of $10 is added if the cart subtotal is $100 or more.
• Adding the Fee: The add_fee() method is used to specify the fee’s name and amount.

4. Conditional Logic for Fees

You can customize the fee based on various conditions, such as:

User Roles: Check if the user is a specific role (e.g., ‘wholesale_customer’).
Product Types: Apply fees based on the types of products in the cart.
Order Totals: Set different fees for varying order totals.

5. Considerations for Taxes and Notifications
Tax Settings: Ensure that your fees are set to be taxable or non-taxable based on your store’s tax settings. You can do this by adding a third parameter to the add_fee() method:

Code:

WC()->cart->add_fee(__(‘Custom Fee’, ‘your-text-domain’), $fee, true); // true for taxable

6. Testing Your Implementation
After implementing your code, thoroughly test the following:

Different Scenarios: Test various cart totals and user roles to ensure the fee is applied correctly.
Checkout Process: Verify that the fee appears correctly in the cart, checkout, and order confirmation emails.

Adding fees to WooCommerce orders programmatically using WooCommerce Hooks is a powerful way to customize your e-commerce store.

By using the woocommerce_cart_calculate_fees hook and implementing conditional logic, you can create a tailored shopping experience for your customers.

Always remember to test your changes thoroughly to ensure a seamless checkout process. If you have any further questions or need assistance, feel free to ask our WooCommerce Expert Team
