php - 基于购物车商品数量的 WooCommerce 运费

Question

我想根据添加到购物车中的产品数量来计算运费，例如，

如果我购买一部手机，则运费为 2.5，如果我购买了两两部以上手机，则运费为 5.0

 <?php

      $qty(1) * 2.5 = 2.5

      $qty(2) * 2.5 = 5.0

      $qty(3) * 2.5 = 5.0

  ?>

那么有什么想法或建议如何根据产品数量计算运费吗？

Answer 1

Updated:

As your question is a bit unclear, you could just need to add [qty]*2.5 in the Flat rate shipping method cost (for each shipping zone) in your wooCommerce shipping settings.

But it will not work if you have 2 different items in cart like: item1 (qty 1) + item2 (qty 1)

所以这个答案在所有情况下都适用:

1) 首先，您需要为每个运输区域设置一个“统一费率”运输方式，成本将设置为 2.5 (在您的 WooCommerce 运输设置中)。

2) 添加此代码将计算每个购物车商品(基于商品总数)新更新的运费:

add_filter( 'woocommerce_package_rates', 'custom_flat_rate_cost_calculation', 10, 2 );
function custom_flat_rate_cost_calculation( $rates, $package )
{
    // The cart count (total items in cart)
    $cart_count = WC()->cart->get_cart_contents_count();
    $taxes = array();

    // If there is more than 1 cart item
    if( $cart_count > 1 ){
        // Iterating through each shipping rate
        foreach($rates as $rate_key => $rate_values){
            // Targeting "Flat Rate" shipping method
            if ( 'flat_rate' === $rate_values->method_id ) {
                // Set the new calculated rate cost
                $rates[$rate_id]->cost = number_format($rates[$rate_id]->cost * $cumulated_active_quantity, 2);
                // Taxes rate cost (if enabled)
                foreach ($rates[$rate_id]->taxes as $key => $tax){
                    if( $rates[$rate_id]->taxes[$key] > 0 ){ // set the new tax cost
                        $taxes[$key] = number_format( $rates[$rate_id]->taxes[$key] * $cumulated_active_quantity, 2 );
                        $has_taxes = true;
                    } else {
                        $has_taxes = false;
                    }
                }
                if( $has_taxes )
                    $rates[$rate_id]->taxes = $taxes; 
            }
        }
    }
    return $rates;
}

代码位于您的事件子主题(或主题)的 function.php 文件中或任何插件文件中。

此代码已在 WooCommerce 3+ 上测试并有效

You will need to refresh shipping zones caches: disabling the Flat rate, then save. And enabling back this rate and save.
