如何在 Woocommerce 中根据购物车总数选择本地提货方法？

Question

我想根据购物车总数通过无线电输入选择本地取货运输方式。我用了这个代码

add_filter('woocommerce_package_rates', 'custom_modify_shipping_methods', 10, 2);
function custom_modify_shipping_methods($rates, $package) {
    // Get the cart total
    $cart_total = WC()->cart->subtotal;

    // Set the threshold for choosing the local pickup shipping method
    $threshold_amount = 2500;

    // Check if the cart total is less than the threshold
    if ($cart_total < $threshold_amount) {
        // Loop through shipping rates
        foreach ($rates as $rate_id => $rate) {
            // Check if it's a local pickup method
            if (strpos($rate_id, 'local_pickup') !== false) {
                // Set the cost to zero (free)
                $rates[$rate_id]->cost = 0;
            }
        }
    }

    return $rates;
}

此代码取消设置所有运输方式，它显示本地提货标签而不是无线电类型输入。输入类型被隐藏，由于未选择送货方式，我无法继续付款。如果购物车总数小于 2500，如何修改代码使本地提货方式默认选择其他方式？

当只有一种可用的运输方式时，相应的单选输入按钮将被隐藏，并且 WooCommerce 自动选择此可用的运输方式...

您使用的代码不适合您的需求。相反，请使用以下内容：

add_filter( 'woocommerce_package_rates', 'filter_shipping_package_rates', 10, 2 );
function filter_shipping_package_rates( $rates, $package ) {
    $threshold_amount = 2600; // Here set the threshold amount
    $subtotal_amount  = 0; // Initializing variable

    // Loop through cart items for the current shipping package
    foreach( $package['contents'] as $item ){
        $subtotal_amount += $item['line_subtotal'] + $item['line_subtotal_tax'];
    }

    // If cart items subtotal is up to the defined threshold amount
    if ( $subtotal_amount >= $threshold_amount ) {
        // Loop through shipping rates for the current shipping package
        foreach( $rates as $rate_key => $rate ) {
            // Targeting local pickup
            if( 'local_pickup' === $rate->method_id ) {
                $taxes = array(); // Initializing variable

                // Loop through tax costs
                foreach ($rate->taxes as $key => $tax) {
                    $taxes[$key] = 0; // Set tax cost to zero
                }
                $rates[$rate_key]->cost = 0; // Set cost to zero
                $rates[$rate_key]->taxes = $taxes; // Set back taxes costs array
            } else {
                unset($rates[$rate_key]); // Remove other rates
            }
        }
    }
    return $rates;
}

代码位于子主题的functions.php 文件中（或插件中）。已测试并有效。

始终清空您的购物车，以刷新缓存的运输数据。
