增加 WooCommerce 购物车中每个类别计数的运费

问题描述

我正在尝试根据购物车中的类别数量(计数)增加运费.到目前为止，我有这个:

I'm trying to increase shipping cost based on number of categories in cart (count). So far I have this:

add_filter( 'woocommerce_package_rates', 'vh_wc_shipping_costs', 20 );

function vh_wc_shipping_costs( $rates ) {
    $increase_cost = 50;
    $cat_ids       = array();
    $count         = 0;

    foreach ( wc()->cart->get_cart() as $cart_item_key => $cart_item ) {
        $cat_ids = array_merge(
            $cat_ids,
            (array) $cart_item['data']->get_category_ids()
        );
        $count   = count( $cat_ids );
    }

    $i=0;

    if ( $count >= 1 ) {
        foreach ( $rates as $rate_key => $rate ) {
            $i++; $i <= $count;

            // Excluding free shipping methods
            if ( 'free_shipping' !== $rate->method_id ) {
                // Get old cost
                $old_cost = $rates[ $rate_key ]->cost;

                // Set rate cost
                $rates[ $rate_key ]->cost = $old_cost + $increase_cost;
            }
        }
    }

    return $rates;
}

但由于某种原因，它不会增加每个额外类别的运费.另外，我想在额外费用中添加一个注释.任何建议表示赞赏.

But it doesn't increment the shipping cost for every extra category for some reason. Also, I would like to add a note to the extra cost. Any Suggestion is appreciated.

推荐答案

由于 StackOverFlow 上的规则当时是一个问题，我只会回答与您的代码相关的第一个问题.

As the rule on StackOverFlow is one question at the time, I will only answer the first question related to your code.

以下代码将为购物车中的每个附加产品类别添加额外的运费(因此不是第一个):

The following code will add an extra shipping cost for each additional product category found in cart (so not for the first one):

add_filter( 'woocommerce_package_rates', 'filter_shipping_rates_costs', 10, 2 );
function filter_shipping_rates_costs( $rates, $package ) {
    $step_cost = 50;
    $term_ids  = array();

    // Loop through cart items for the current shipping package
    foreach( $package['contents'] as $cart_item ){
        $term_ids = array_merge(
            $term_ids,
            (array) $cart_item['data']->get_category_ids()
        );
    }

    $terms_count = count( $term_ids );

    // Loop through shipping rates
    foreach ( $rates as $rate_key => $rate ) {
        // Excluding free shipping methods
        if ( 'free_shipping' !== $rate->method_id && $terms_count > 1 ) {
            // Set rate cost
            $rates[$rate_key]->cost = $rate->cost + ($step_cost * ($terms_count - 1));
        }
    }

    return $rates;
}

现在，如果您想为购物车中的每个类别添加额外的运费，请使用以下内容:

Now if you want to add an extra shipping cost for each category found in cart, use the following:

add_filter( 'woocommerce_package_rates', 'filter_shipping_rates_costs', 10, 2 );
function filter_shipping_rates_costs( $rates, $package ) {
    $step_cost = 50;
    $term_ids  = array();

    // Loop through cart items for the current shipping package
    foreach( $package['contents'] as $cart_item ){
        $term_ids = array_merge(
            $term_ids,
            (array) $cart_item['data']->get_category_ids()
        );
    }

    $terms_count = count( $term_ids );

    // Loop through shipping rates
    foreach ( $rates as $rate_key => $rate ) {
        // Excluding free shipping methods
        if ( 'free_shipping' !== $rate->method_id && $terms_count > 0 ) {
            // Set rate cost
            $rates[$rate_key]->cost = $rate->cost + ($step_cost * $terms_count);
        }
    }

    return $rates;
}

代码位于活动子主题(或活动主题)的 functions.php 文件中.经测试有效.

Code goes in functions.php file of your active child theme (or active theme). Tested and works.

刷新运输缓存:

1. 此代码已保存在您的functions.php 文件中.
   
2. 在送货区域设置中，禁用/保存任何送货方式，然后启用返回/保存.
   
   大功告成，您可以对其进行测试.
   

1. This code is already saved on your functions.php file.
   
2. In a shipping zone settings, disable / save any shipping method, then enable back / save.
   
   You are done and you can test it.
