我最近在我的新笔记本电脑中安装了最新版本的Python（3.6），当我尝试导入netCDF4 add_action('woocommerce_checkout_process', 'wh_alphaCheckCheckoutFields');
function wh_alphaCheckCheckoutFields() {
$billing_first_name = filter_input(INPUT_POST, 'billing_first_name');
$billing_last_name = filter_input(INPUT_POST, 'billing_last_name');
$shipping_first_name = filter_input(INPUT_POST, 'shipping_first_name');
$shipping_last_name = filter_input(INPUT_POST, 'shipping_last_name');
$ship_to_different_address = filter_input(INPUT_POST, 'ship_to_different_address');
if (empty(trim($billing_first_name)) || !ctype_alpha($billing_first_name)) {
wc_add_notice(__('Only alphabets are alowed in <strong>Billing First Name</strong>.'), 'error');
}
if (empty(trim($billing_last_name)) || !ctype_alpha($billing_last_name)) {
wc_add_notice(__('Only alphabets are alowed in <strong>Billing Last Name</strong>.'), 'error');
}
// Check if Ship to a different address is set, if it's set then validate shipping fields.
if (!empty($ship_to_different_address)) {
if (empty(trim($shipping_first_name)) || !ctype_alpha($shipping_first_name)) {
wc_add_notice(__('Only alphabets are alowed in <strong>Shipping First Name</strong>.'), 'error');
}
if (empty(trim($shipping_last_name)) || !ctype_alpha($shipping_last_name)) {
wc_add_notice(__('Only alphabets are alowed in <strong>Shipping Last Name</strong>.'), 'error');
}
}
}
时出现此错误。我正在使用Windows 10.有关解决方案的任何想法吗？
