在WooCommerce中按商品类别同步自定义价格并添加购物车利润率计算

Hey there! Let's get that WooCommerce custom pricing setup working exactly how you need it. You already started with the woocommerce_product_get_price filter, so let's expand that to handle category-based base prices, plus add the logic to apply the 2.5x markup when items are added to the cart.

Here's the complete code to add to your theme's functions.php file: #

First, we'll set the base prices for each category on all frontend pages except the cart/checkout:

// Set base category prices on product pages, archives, etc.
add_filter('woocommerce_product_get_price', 'product_price_new', 10, 2);
add_filter('woocommerce_product_variation_get_price', 'product_price_new', 10, 2); // Handle variable products too
function product_price_new($price, $product) {
    // Only apply base prices outside cart/checkout
    if (!is_cart() && !is_checkout()) {
        // Get all category slugs for the product
        $product_cats = wp_get_post_terms($product->get_id(), 'product_cat', array('fields' => 'slugs'));
        
        // Assign base price based on category
        if (in_array('category-a', $product_cats)) {
            $price = 5;
        } elseif (in_array('category-b', $product_cats)) {
            $price = 10;
        } elseif (in_array('category-c', $product_cats)) {
            $price = 15;
        }
    }
    return $price;
}

Next, we'll add the 2.5x markup to items in the cart and checkout:

// Apply 2.5x markup to cart items
add_action('woocommerce_before_calculate_totals', 'apply_cart_price_markup', 10, 1);
function apply_cart_price_markup($cart) {
    // Don't run on admin pages unless it's an AJAX request
    if (is_admin() && !defined('DOING_AJAX')) return;
    
    // Loop through each item in the cart
    foreach ($cart->get_cart() as $cart_item) {
        $product = $cart_item['data'];
        $product_cats = wp_get_post_terms($product->get_id(), 'product_cat', array('fields' => 'slugs'));
        
        // Get the base price based on category
        $base_price = 0;
        if (in_array('category-a', $product_cats)) {
            $base_price = 5;
        } elseif (in_array('category-b', $product_cats)) {
            $base_price = 10;
        } elseif (in_array('category-c', $product_cats)) {
            $base_price = 15;
        }
        
        // Apply markup if we have a valid base price
        if ($base_price > 0) {
            $marked_up_price = $base_price * 2.5;
            $cart_item['data']->set_price($marked_up_price);
        }
    }
}

Important Notes: #

• Replace category-a, category-b, category-c with your actual product category slugs (you can find these in the WooCommerce Category edit page under "Slug").
• The second filter (woocommerce_product_variation_get_price) ensures variable products in these categories also get the correct base price.
• The cart action runs every time cart totals are calculated, so the markup stays applied even if quantities change.
• We added a check to avoid running the cart logic on admin pages, which prevents unexpected behavior in the backend.

This setup will show the base price (5/10/15) on product pages and archives, then automatically multiply by 2.5 when the item is added to the cart and during checkout.
