在Woocommerce中每3件商品的统一费用运送中增加额外的费用

标签: php wordpress woocommerce cart shipping-method

我正在经营woocommerce商店,并使用统一运费$15。我写了一个公式,为每个其他项目添加$1.25

  

13.50 +(1.25 * [数量])

为附加的每个项目使用“统一费率设置| $1.25

$1.25 for Additional Each Item

但是我想为每3个项目添加此费用$1.25。我的意思是3、6、9、12等...

谁能告诉我该怎么做?任何帮助表示赞赏。

以下代码将为每3件商品(3、6、9…) 增加统一费用运送方式的费用。

您需要用简单的初始费用代替您的公式来更改运输费用。

  

您可能必须在“运输选项”标签下的常规运输设置中启用“启用调试模式”,才能暂时禁用运输缓存。

代码(您将在其中设置额外的运费)

add_filter('woocommerce_package_rates', 'shipping_additional_cost_each_three_items', 12, 2);
function shipping_additional_cost_each_three_items( $rates, $package ){
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return $rates;

    // HERE set your additional shipping cost
    $additional_cost = 1.25;
    $items_count = WC()->cart->get_cart_contents_count();

    // Loop through the shipping taxes array
    foreach ( $rates as $rate_key => $rate ){
        $has_taxes = false;
        // Targetting "flat rate"
        if( 'flat_rate' === $rate->method_id ){
            // Get the initial cost
            $initial_cost = $new_cost = $rates[$rate_key]->cost;
            // Adding to cost the additional cost each 3 items (3, 6, 9 …)
            for($i = 0; $i <= $items_count; $i+=3){
                $new_cost += $additional_cost;
            }
            // Set the new cost
            $rates[$rate_key]->cost = $new_cost;

            // Taxes rate cost (if enabled)
            $taxes = [];
            // Loop through the shipping taxes array (as they can be many)
            foreach ($rates[$rate_key]->taxes as $key => $tax){
                if( $rates[$rate_key]->taxes[$key] > 0 ){
                    // Get the initial tax cost
                    $initial_tax_cost = $new_tax_cost = $rates[$rate_key]->taxes[$key];
                    // Get the tax rate conversion
                    $tax_rate    = $initial_tax_cost / $initial_cost;
                    // Set the new tax cost
                    $taxes[$key] = $new_cost * $tax_rate;
                    $has_taxes   = true; // Enabling tax
                }
            }
            if( $has_taxes )
                $rates[$rate_key]->taxes = $taxes;
        }
    }
    return $rates;
}

代码进入您的活动子主题(或活动主题)的function.php文件中。经过测试,可以正常工作。

  

请不要忘记在出厂设置中禁用“启用调试模式”选项。


基于您的第二条评论的答案:

您将替换此块:

// Adding to cost the additional cost each 3 items (3, 6, 9 …)
for($i = 0; $i <= $items_count; $i+=3){
    $new_cost += $additional_cost;
}

通过以下方式:

// Adding to cost an additional fixed cost for the 2nd item
if($items_count >= 2){
    $new_cost += 6.21; 
}

// Adding to cost the additional cost each 3 items (3, 6, 9 …)
for($i = 0; $i <= $items_count; $i+=3){
    $new_cost += $additional_cost;
}

<?php
$number = 13;
$all_number = 1;
for($i=1;$i<=13;$i++){
    if ($i % 3 == 0){
        $all_number = $all_number + 1;
    }
}
$price_new_data = $old_price*$all_number;
$price = 13.50+($price_new_data*$product_quenty);
?>
