同步力量根据woocommerce中的产品数量进行销售

Question

如果客户添加5个产品1附件应该添加，我想根据产品数量强制销售。如果他们添加超过5，添加2个配件。 因此配件应该加上五个的倍数。

Answer 1

试试这个：

    add_action( 'woocommerce_add_to_cart', 'prefix_add_additional_product', 10, 6 );
/**
 * Adds additional product to cart based on the quantity of an added product
 */
function prefix_add_additional_product( $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data ) {
    // Get the cart
    $cart = WC()->cart->get_cart();

    // Nothing, if the cart is empty
    if ( 0 == count( $cart ) ) {
        return;
    }

    // Enter the free product ID
    $additional_product_id = 96;

    // Don't add accessory when adding the same accessory
    $added_product_id = 0 < $variation_id ? $variation_id : $product_id;
    if ( $added_product_id == $additional_product_id ) {
        return;
    }

    // You can add checks for specific product ID or some other requirements here

    $additional_product_quantity = (int) ( $quantity / 5 );

    WC()->cart->add_to_cart( $additional_product_id, $additional_product_quantity );
}

代码应将$additional_product_id添加到购物车，其数量与添加的产品与购物车数量之间的数量相差5。 代码被挂钩到add to cart hook。
