WooCommerce add fee filter

WooCommerce add fee filter is a powerful feature in WooCommerce that allows developers to add custom fees to orders during the checkout process. This filter can be used to apply additional charges based on various conditions such as order total, shipping method, product category, or any other custom criteria.

When a customer proceeds to the checkout page in WooCommerce, the add fee filter can be used to dynamically add extra charges to the order total. This can be useful for implementing features like handling fees, processing fees, or any other custom charges that need to be applied to orders.

Here is an example of how you can use the add fee filter in WooCommerce to add a handling fee of $5 to the order total:

function flashify_add_handling_fee( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) ) {
        return;
    }
    
    $handling_fee = 5;
    
    $cart->add_fee( 'Handling Fee', $handling_fee );
}
add_action( 'woocommerce_cart_calculate_fees', 'flashify_add_handling_fee' );

In the above example, we have created a custom function flashify_add_handling_fee that adds a handling fee of $5 to the cart using the add_fee method. This function is hooked to the woocommerce_cart_calculate_fees action, which is triggered when the cart total is calculated.

By using the WooCommerce add fee filter, developers can enhance the functionality of their WooCommerce stores and provide a more customized shopping experience for customers. This filter opens up a wide range of possibilities for implementing various pricing strategies, promotions, and additional charges in WooCommerce.
