基于 WooCommerce 中的产品 ID 的 2 种不同固定产品折扣的优惠券 [英] Coupon with 2 differents fixed product discounts based on product IDs in WooCommerce

问题描述

我遇到过

具有 2 个不同百分比的优惠券基于 Woocommerce 中产品类别的折扣

其中显示了如何更改设置类别的折扣百分比.我想在我的商店中实施一个夏季折扣代码，为选择的产品提供 20 英镑的折扣.

Which shows how to alter % discounts for set categories. I want to implement a summer discount code on my store which gives £20 off to a selection of products.

优惠券代码 summer21 设置为仅对以下允许的产品 ID 应用固定产品折扣

The coupon code summer21 is set to apply a fixed product discount on only the following allowed product IDs

• 2523, 119800, 119886 &120253

对于 4 个中的 3 个，应享受 20 英镑的折扣

On 3 of the 4 a £20 discount should apply

但是如果产品 ID = 119886，那么应该只打折 10 英镑

But if the product ID = 119886, then only £10 should be discounted

我尝试将代码修改为以下内容，但不幸的是没有达到预期的结果.我错过了什么?

I've tried modifying the code to the following, but unfortunately without the desired result. What am I missing?

add_filter( 'woocommerce_coupon_get_discount_amount', 'alter_shop_coupon_data', 20, 5 );
function alter_shop_coupon_data( $round, $discounting_amount, $cart_item, $single, $coupon ){

    ## ---- Your settings ---- ##

    // Related coupons codes to be defined in this array (you can set many)
    $coupon_codes = array('Summer21');

    // Product categories for only £10 discount (IDs, Slugs or Names)
    $product_category10 = array('119886'); // for £10 discount

    $second_discount = 10; // £10

    ## ---- The code: Changing the discount to £10 for specific products ---- ##

    if ( $coupon->is_type('fixed_product') && in_array( $coupon->get_code(), $coupon_codes ) ) {
        if( has_term( $product_category10, 'product_cat', $cart_item['product_id'] ) ){
            $discount = $discounting_amount - $second_discount;
            $round = round( min( $discount, $discounting_amount ), wc_get_rounding_precision() );
        }
    }
    return $round;
}

此代码也仅更改购物车价格，但并未在产品页面上显示正确的显示价格.

This code also only changes the cart price, but does not show the correct display prices on the product pages.

推荐答案

你的代码有几个错误

• has_term() 不适用，我们使用 in_array() 代替
• 不考虑每个产品的购物车商品数量.

• has_term() is not applicable, we are using in_array() instead
• Cart item quantity per product is not taken into account.

为了使这个答案有效，我们应用了一些步骤

To make this answer work, we apply some steps

第一步，优惠券设置:

• 标题:summer21
• 一般>折扣类型:固定产品折扣
• 一般>优惠券金额:20
• 使用限制>产品:其中产品 ID:2523、119800、119886、120253

第二步，代码功能里面的设置:

Second step, settings inside the code function:

• 优惠券代码:将您的优惠券代码设置为小写
• 产品 ID，第二次折扣:119886
• 设置第二个折扣:10

所以你得到:

function filter_woocommerce_coupon_get_discount_amount( $round, $discounting_amount, $cart_item, $single, $coupon ) {   
    // Related coupons codes to be defined in this array
    $coupon_codes = array( 'summer21' );

    // Product IDs, for second discount
    $product_ids = array( 119886 ); 

    // Second discount
    $second_discount = 10;

    // Changing the discount for specific product Ids
    if ( $coupon->is_type('fixed_product') && in_array( $coupon->get_code(), $coupon_codes ) ) {                
        // Search for product ID in array product IDs
        if ( in_array( $cart_item['product_id'], $product_ids ) ) {
            // Get cart item quantity
            $cart_item_qty = is_null( $cart_item ) ? 1 : $cart_item['quantity'];
            
            // Discount
            $discount = $coupon->get_amount() - $second_discount;           
            $discount = $single ? $discount : $discount * $cart_item_qty;
            
            $round = round( min( $discount, $discounting_amount ), wc_get_rounding_precision() );
        }       
    }
    
    return $round;
}
add_filter( 'woocommerce_coupon_get_discount_amount', 'filter_woocommerce_coupon_get_discount_amount', 10, 5 );
