在WooCommerce中为特定类别的最便宜商品打折 [英] Discounting the cheapest item for a specific category in WooCommerce

问题描述

我想根据产品类别对Woocommerce中最便宜的购物车产品打折.根据"产品的购物车折扣在Woocommerce中价格更低" 效果很好的答案代码.

I wound like to discount the cheapest cart item in Woocommerce, based on a product category. Based on "Cart discount for product that cost less in Woocommerce" answer code that works perfectly.

但是如何使其仅适用于特定产品类别.

But how to make it work for a specific product category only.

这个想法是在购物车中有2种商品，并且针对特定商品类别的最便宜商品有折扣.

The idea is to have 2 products in the shopping cart and have a discount on the cheapest item for a specific product category.

推荐答案

已更新-仅限已定义产品类别中的2个项目.

Updated - Limiting to 2 items from the defined product category.

以下将对特定产品类别(将在代码中定义)执行相同的操作:

The following will do the same for a specific product category (to be defined in the code):

add_action('woocommerce_cart_calculate_fees', 'discount_on_cheapest_cart_item', 20, 1 );
function discount_on_cheapest_cart_item( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // Settings
    $categories = ['tshirts']; // Your product categories (coma separated)
    $percentage = 10; // 10 % discount

    // Only for 2 items or more
    if ( $cart->get_cart_contents_count() < 2 ) return;

    // Initialising
    $discount = 0;
    $item_prices = array();

    // Loop though each cart items and set prices in an array
    foreach ( $cart->get_cart() as $cart_item ) {
        if( has_term( $categories, 'product_cat', $cart_item['product_id'] ) ) {
            $product_prices_excl_tax[] = wc_get_price_excluding_tax( $cart_item['data'] );
        }
    }

    // We set the fee for 2 items of the defined product category
    if( count($product_prices_excl_tax) == 2 ) {

        sort($product_prices_excl_tax);

        $discount = reset($product_prices_excl_tax) * $percentage / 100;

        $cart->add_fee( sprintf( __("Discount on cheapest %s"), '('.$percentage.'%)' ), -$discount );
    }
}

代码进入您的活动子主题(或活动主题)的function.php文件中.应该可以.

Code goes in function.php file of your active child theme (or active theme). It should works.
