增加 WooCommerce 购物车中每个类别计数的运费

Question

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：

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;
}

但出于某种原因，它不会增加每个额外类别的运费。另外，我想对额外费用进行说明。任何建议表示赞赏。

由于当时Whosebug上的规则是一个问题，所以我只回答与您的代码相关的第一个问题。

以下代码将为在购物车中找到的每个额外产品类别添加额外的运费（因此不是第一个）：

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，请使用以下方法：

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;
}

代码进入您的活动子主题（或活动主题）的 functions.php 文件。已测试并有效。

Refresh the shipping caches:

This code is already saved on your functions.php file.

In a shipping zone settings, disable / save any shipping method, then enable back / save.

You are done and you can test it.
