WooCommerce-制作一组优惠券，向订单添加固定费用 [英] WooCommerce - Make a set of coupons adding a fixed fee to an order

问题描述

客户的要求很奇怪:他们希望使用一组优惠券代码向订单添加费用.这可能吗?

A client has a very odd request: they would like for a set of coupon codes to add a fee to an the order. Is this possible?

他们试图解决的问题是:

The problem they are trying to solve is this:

目前，该商店可免费送货至美国48个较低的国家/地区，为此我已正确配置了运输等级和餐桌费率.但是，客户在日常交易网站上出售的优惠券应该会消除免费送货的好处，并增加固定的送货费用.

Currently the store offers free shipping to the lower 48 United States, for which I have shipping classes and table rates properly configured. However, the coupons the customer has sold on a daily deal site are supposed to remove the free shipping benefit and add a fixed shipping fee.

如何实现呢?

推荐答案

是的，您可以使用该代码段代码(针对一组优惠券)进行操作:

Yes you can do it with that snippet code (for a set of coupons):

function coupon_add_cart_fee( $bookable_total = 0 ) {
    $has_coupon = false;

    // Set here your specials coupons slugs (one by line - last one have no coma)
    $coupon_codes = array (
        'your_coupon_code_slug1',
        'your_coupon_code_slug2',
        'your_coupon_code_slug3' 
    );

    // Set here your fee amount or make fees calculation (see the links in reference)
    $fee = 20;

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // checking if that "special" coupon is applied to customer cart
    foreach ($coupon_codes as $coupon_code) {
        if ( WC()->cart->has_discount( $coupon_code ) ) {

            // If yes apply the fee to the cart
            if ( !$has_coupon ) {
                $has_coupon = true;
                break;
            }
        }
    }

    if ( $has_coupon ) {
        WC()->cart->add_fee( 'Fees: ', $fee, false );
    }
}
add_action( 'woocommerce_cart_calculate_fees','coupon_add_cart_fee' );

此代码已经过测试，可以正常工作. 它会出现在您活动的子主题或主题的function.php文件中.

使用 add_fee()方法的税收选项

重要提示:使用

IMPORTANT: The fact that TAX is working or not with add_fee() method depends first of your tax settings in woocommerce.

Class WC_Cart add_fee()方法，向购物车添加了额外费用.

add_fee( string $name, float $amount, boolean $taxable = false, string $tax_class = ''  )> <!-- language: lang-css -->

Parameters:
    $name      Unique name for the fee. Multiple fees of the same name cannot be added.
    $amount    Fee amount.
    $taxable   (default: false) Is the fee taxable?
    $tax_class    (default: '') The tax class for the fee if taxable. A blank string is standard tax class.
