Example Code

Here is an example of how you can use custom code to update shipping rules for new products:

php
// Update shipping rules for new products
function update_shipping_rules_for_new_products($product_id) {
    // Get the product categories
    $product_categories = get_the_terms($product_id, 'product_cat');

    // Loop through each product category
    foreach ($product_categories as $category) {
        // Get the shipping methods for the category
        $shipping_methods = wc_get_shipping_methods_for_category($category->slug);

        // Loop through each shipping method
        foreach ($shipping_methods as $shipping_method) {
            // Update the shipping rates for the method
            update_shipping_rates($shipping_method);
        }
    }
}

// Update shipping rates for a shipping method
function update_shipping_rates($shipping_method) {
    // Get the shipping rates for the method
    $shipping_rates = wc_get_shipping_rates($shipping_method);

    // Loop through each shipping rate
    foreach ($shipping_rates as $rate) {
        // Update the rate based on the product categories
        if (in_array('category-slug-1', $product_categories)) {
            $rate->cost = 10.00;
        } elseif (in_array('category-slug-2', $product_categories)) {
            $rate->cost = 15.00;
        }
    }
}

// Hook to trigger the function when a new product is added
add_action('woocommerce_new_product', 'update_shipping_rules_for_new_products');
