【问题描述】：

我正在使用以下代码将 WooCommerce 结帐输入限制为仅限字母字符（感谢这篇文章：Alphabet characters only for billing and shipping names in WooCommerce）。但是，这也会将每个结帐字段标记为“必填”，例如，即使客户不想添加任何订单 cmets，他们也必须添加一些内容才能完成订单。如何编辑它以便不需要所有字段？非常感谢您的帮助！

/* remove special charaters from checkout ? */

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');
$order_comments = filter_input(INPUT_POST, 'order_comments');
$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');

if (empty(trim($order_comments)) || !ctype_alpha($order_comments)) 
    wc_add_notice(__('Only alphabets are alowed in <strong>Delivery 
Instructions</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');

我的回答有帮助吗？

嗨 Bhautik，它似乎确实有效，但现在代码也禁止使用我需要允许的单词之间的空格。可以更改为在单词之间包含空格吗？非常感谢！

我找到了答案！将 Order cmets 行更改为以下内容： if ( !empty( trim( $order_cmets ) ) && !ctype_alpha(str_replace(' ', '', $order_cmets)) )

欢迎...很高兴为您提供帮助。如果这个答案对你有帮助，那么你可以accept 答案，如果你喜欢/想要你也可以upvote 答案，谢谢。

【参考方案1】：

改变这个条件

if (empty(trim($order_comments)) || !ctype_alpha($order_comments)) 

到这里

if ( !empty( trim( $order_comments ) ) && !ctype_alpha( $order_comments ) )
