通过Hook实现WooCommerce变体：寻求多维度定价适配的插件或函数

Hey there! Let's tackle this product variation pricing challenge you're facing—four attributes (color, lining, size, leather type) with custom price adjustments, right? I’ve helped many users work through similar needs, so here are my top recommendations, split into plugin options and custom code hooks depending on your setup:

推荐插件（无需开发，快速配置） #

If you prefer a no-code approach, these plugins are built to handle multi-attribute pricing flexibly:

• WooCommerce Product Add-Ons Premium：This official paid plugin is a solid choice. It lets you add unlimited custom attributes, and you can set price increments/decrements for each option. For example, you could add $50 for "Italian leather", $30 for "wool lining"—perfect for your four dimensions. It integrates seamlessly with core WooCommerce, so you won’t run into compatibility headaches.
• Advanced Product Variations for WooCommerce：Great if you’re on a budget (it has a free tier with basic features, plus a paid version for advanced stuff). It supports conditional pricing for attribute combinations (like "XXL size + Italian leather" adding an extra $65) and makes managing large variation sets way easier than manually creating each one.
• Product Variations Swatches for WooCommerce (Premium)：While it’s known for making variant options look nicer (color swatches, size buttons), its paid version also includes robust multi-attribute pricing controls. It’s ideal if you want to improve user experience and handle your pricing needs in one tool.

Quick side note: If you haven’t tried core WooCommerce’s native variable products yet—you can create a variable product, add your four attributes, generate all possible variants, and set prices for each. But this gets tedious if you have dozens/hundreds of combinations, which is where the plugins above save time.

自定义Hook实现（适合有开发能力的场景） #

If none of the plugins fit your exact needs (like super complex conditional pricing logic), you can use WooCommerce hooks to build a custom solution. Here’s a practical example using the woocommerce_before_calculate_totals hook:

add_action('woocommerce_before_calculate_totals', 'custom_multi_attribute_pricing', 10, 1);
function custom_multi_attribute_pricing($cart) {
    // Skip admin area unless it's an AJAX request
    if (is_admin() && !defined('DOING_AJAX')) return;

    foreach ($cart->get_cart() as $item_key => $cart_item) {
        $product = $cart_item['data'];
        // Get selected attribute values (replace the slugs with your actual attribute slugs)
        $selected_color = $cart_item['variation']['attribute_pa_color'] ?? '';
        $selected_lining = $cart_item['variation']['attribute_pa_lining'] ?? '';
        $selected_size = $cart_item['variation']['attribute_pa_size'] ?? '';
        $selected_leather = $cart_item['variation']['attribute_pa_leather-type'] ?? '';

        $price_adjustment = 0;
        // Add price adjustments based on selected attributes
        if ($selected_color === 'crimson-red') $price_adjustment += 20;
        if ($selected_lining === 'premium-wool') $price_adjustment += 30;
        if ($selected_size === 'xxl') $price_adjustment += 15;
        if ($selected_leather === 'italian-full-grain') $price_adjustment += 50;

        // Update the product price
        $product->set_price($product->get_regular_price() + $price_adjustment);
    }
}

Just replace the attribute slugs (like pa_color) and option values (like crimson-red) with your own. You can add this code to your theme’s functions.php file or a custom plugin.

Hope one of these options works smoothly for you! If you hit any snags with configuration or code, feel free to share more details and I’ll help troubleshoot.
