我需要根据购物车中的产品数量添加折扣,此折扣将适用于购物车的总数.没有使用优惠券还有其他选择吗？

Answer 1

我更喜欢这种方式,我认为更清洁

// Hook before calculate fees
add_action('woocommerce_cart_calculate_fees' , 'add_custom_fees');

/**
 * Add custom fee if more than three article
 * @param WC_Cart $cart
 */
function add_custom_fees( WC_Cart $cart ){
    if( $cart->cart_contents_count < 3 ){
        return;
    }

    // Calculate the amount to reduce
    $discount = $cart->subtotal * 0.1;
    $cart->add_fee( 'You have more than 3 items in your cart, a 10% discount has been added.', -$discount);
}
