应针对 woocommerce 中的 2 个不同类别应用两组不同的折扣

Question

这是与 woocommerce 集成的 WordPress 网站。在本店中，主要有两大类Category1和Category2。

我想针对 2 个不同的类别设置两组不同的折扣。

例如：

类别 1 的场景：

购买 $500-$999 可享受 5% 的折扣
购买 $1000-$2000 即可享受 15% 的折扣
购买 $2001-$5000 可享受 25% 的折扣

类别 2 的场景：

购买 $500-$999 可享受 20% 的折扣
购买 $1000-$2000 即可享受 40% 的折扣
购买 $2001-$5000 可享受 60% 的折扣

考虑一下我是否从 Category1 购买价值 1000 美元的 product1 和 product2，以及从 Category2 购买价值 4000 美元的 product5 和 product6。

所以摘要购物车应该如下所示：

    Cart subtotal:                       00
    Category 1 Discount (15%) of 00: -0
    Category 2 Discount (60%) of 00  -00
    Amount to Pay:                       50

应根据每个类别的小计应用折扣。尝试了很多插件和自定义代码，都无法实现woocoomerce中的功能。

您能否建议任何插件或自定义代码来实现此功能？

更新：

我尝试了以下基于线程的代码。

尝试根据 2 个条件应用累进折扣。

基于购物车价值
关于特定类别。

但尝试的代码无效。我需要在此代码中更改什么？我需要为 2 个不同的类别设置累进折扣。

add_action( 'woocommerce_cart_calculate_fees', 'cart_items_quantity_wise_discount', 10, 1 );

    function cart_items_quantity_wise_discount($cart_object) {

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

        // Set HERE your category (can be an ID, a slug or the name)
        $category = '224'; // our category id

        $category_count = 0;
        $category_total = 0;
        $discount = 0;

        // Iterating through each cart item
        foreach($cart_object->get_cart() as $cart_item):
        //print_r($cart_item);exit;
            if( has_term( $category, 'product_cat', $cart_item['product_id']) ):
                $category_count += $cart_item['quantity'];
                $category_total += $cart_item["line_total"]; // calculated total items amount (quantity x price)
            endif;

        endforeach;

        $discount_text = __( 'Quantity discount of ', 'woocommerce' );

        if ( $category_total >=2000 && $category_total <=2999 ) {
            $discount -= $category_total * 0.3; // Discount of 10% 
            $discount_text_output = $discount_text . '10%';
        } 
        elseif ( $category_total >=3000 && $category_total <=4999 ) {
            $discount -= $category_total * 0.15; // Discount of 15%
            $discount_text_output = $discount_text . '15%';
        }
    // Adding the discount
        if ( $discount != 0 && $category_count >= 12 )
            $cart_object->add_fee( $discount_text_output, $discount, false );

        // Note: Last argument in add_fee() method is related to applying the tax or not to the discount (true or false)
    }

第二次更新（第 2 版）- 我尝试了以下代码。但类别明智的折扣不会影响我的结帐页面。你能看看这个以及我在这段代码中做错了什么吗？

add_action( 'woocommerce_cart_calculate_fees', 'cart_items_quantity_multiple_discounts', 10, 1 );
function cart_items_quantity_multiple_discounts( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // HERE set your 2 product category term names
    $category1 = 'Appliances';
    $category2 = 'Electronics';

    $total1 = $total2 = $percentage1 = $percentage2 = 0;

    // Loop through cart items
    foreach( $cart->get_cart() as $cart_item ) {
        if( has_term( $category1, 'product_cat', $cart_item['product_id']) ) {
            $total1 += $cart_item["line_total"]; // Excluding taxes
        } elseif( has_term( $category2, 'product_cat', $cart_item['product_id']) ) {
            $total2 += $cart_item["line_total"]; // Excluding taxes
        }
    }

    // All Amounts need to be set without taxes

    // First category "Appliances" progressive percentage discount
    if ( $total1 >= 1000 && $total1 < 1500 ) { // <== set excluding taxes 
        $percentage1 = 5;
    }elseif ( $total1 >= 1500 && $total1 < 2500 ) { // <== set excluding taxes 
        $percentage1 = 10;
    }elseif ( $total1 >= 2500 ) { // <== set excluding taxes amounts
        $percentage1 = 15;
    }

    // Second category "Electronics" progressive percentage discount
    if ( $total2 >= 1000 && $total2 < 1500 ) { // <== set excluding taxes amounts
        $percentage2 = 10;
    }elseif ( $total2 >= 1500 && $total2 < 2500 ) { // <== set excluding taxes amounts
        $percentage2 = 15;
    }elseif ( $total2 >= 2500 ) { // <== set excluding taxes amounts
        $percentage2 = 20;
    }

    // Set the first discount for "Appliances"
    if( $percentage1 > 0 ){
        $discount1   = $total1 * $percentage1 / 100;
        $label_text1 = sprintf( __( '%s Discount (%s) of %s', 'woocommerce' ),
            $category1, $percentage1 . '%', strip_tags(wc_price($total1)));
        $cart->add_fee( $label_text1, -$discount1 );
    }

    // Set the Second discount for "Electronics"
    if( $percentage2 > 0 ){
        $discount2   = $total2 * $percentage2 / 100;
        $label_text2 = sprintf( __( '%s Discount (%s) of %s', 'woocommerce' ),
            $category2, $percentage2 . '%', strip_tags(wc_price($total2)));
        $cart->add_fee( $label_text2, -$discount2 );
    }

    // Note: Last argument "taxable" in add_fee() method is always true for negative fees (discounts)
}

Answer 1

@Vinayagam - 请在您的子主题中使用以下代码 functions.php。我已经测试过并且工作正常。

    add_action( 'woocommerce_cart_calculate_fees', 'cart_items_quantity_multiple_discounts', 10, 1 );

    function cart_items_quantity_multiple_discounts( $cart ) {
        if ( is_admin() && ! defined( 'DOING_AJAX' ) )
            return;

        // HERE set your 2 product category term names
        $category1 = 250;//Appliances
        $category2 = 224;//Electronics

        $pdt_id_1 = $pdt_id_2 = $total1 = $total2 = $percentage1 = $percentage2 = 0;
        //$pdt_id_1 - Category One;
        //$pdt_id_2 - Category Two;
enter code here
        // Loop through cart items
        foreach( $cart->get_cart() as $cart_item ) {
            $_product = $cart_item['data'];
            $terms = get_the_terms( $_product->id, 'product_cat' );
            foreach ($terms as $term) {
                $_categoryid = $term->parent;
                if ( $_categoryid === $category1 and $pdt_id_1!=$_product->id) {
                    $total1 += $cart_item["line_total"];
                    $pdt_id _1= $_product->id;
                }
                else if ( $_categoryid === $category2 and $pdt_id_2!=$_product->id) {
                    $total2 += $cart_item["line_total"];
                    $pdt_id_2 = $_product->id;
                }
            }
        }

        // All Amounts need to be set without taxes

        // Set the first discount for "Appliances"
        if( $percentage1 > 0 ){

            $cart->add_fee( $label_text1, -$discount1, true, '');
        }

        // Set the Second discount for "Electronics"
        if( $percentage2 > 0 ){
            $discount2   = $total2 * $percentage2 / 100;
