自定义 WooCommerce 运输方式

Question

我有这个工作代码，可以在 woocommerce 设置 > 运输区域下正确生成和保存自定义运输方法。

我的问题是我无法在结帐页面上显示运输方式。

任何有关如何解决此问题并可能扩展代码的帮助将不胜感激。

add_filter('woocommerce_shipping_methods', 'add_local_shipping');
function add_local_shipping($methods) {
    $methods['local_shipping'] = 'Local_Shipping_Method';

您尝试的方式是错误的。并且不建议将文本域保存在变量或方法中。

创建自定义运输方式您必须按照我在您的代码上更正的这些步骤进行操作。

希望这可以帮助。您可以了解更多关于如何创建新的送货方式here。随意
