如何解决woocommerce未选择运输方式，自定义运输方式
我正在尝试制定自定义送货方式
费率是根据某些结帐表单值计算得出的。
费率显示正确，如下所示。
但是，当我下订单时，出现以下错误： 没有选择运送方式。
如果我绕过class-wc-checkout.php中的以下行，我可以摆脱此错误消息
foreach ( WC()->shipping()->get_packages() as $i => $package ) {
if ( ! isset( $chosen_shipping_methods[ $i ],$package['rates'][ $chosen_shipping_methods[ $i ] ] ) ) {
$errors->add( 'shipping',__( 'No shipping method has been selected. Please double check your address,or contact us if you need any help.','woocommerce' ) );
}
但是，送货方式不会出现在确认页面上。
在class-wc-checkout.php validate-checkout fn处检查$ package ['rates']。 数组为空
function afelivery_shipping_init()
{
if ( ! class_exists( 'WC_Shipping_Afelivery' ) ) {
class WC_Shipping_Afelivery extends WC_Shipping_Method
{
