【问题描述】：

我有一个名为 gift 的自定义字段，我现在正尝试根据 billing_email 字段验证它。也就是说，如果客户填写的赠品字段和账单邮件是同一封邮件，点击“完成订单”按钮时应该会报错。

它不起作用。任何想法为什么？这是代码。

// verify that billing email and gift email are not the same
function billing_email_and_gift_validation( $posted ) 
$checkout = WC()->checkout;
if ( strcmp( $posted['billing_email'] == $posted['gift'] )) 
wc_add_notice( __( 'To send as gift, you cannot send it to yourself. That\'s the point of a gift, is it not?', 'woocommerce' ), 'error' );  
add_action( 'woocommerce_after_checkout_validation', 'billing_email_and_gift_validation', 10, 2 );

如果有人可以提供帮助，谢谢大家。

【参考方案1】：

我已将此验证与您之前制作的此问题代码中的礼物验证合并，因此您将从您的实际代码中删除它，因为此函数同时处理它们：

add_action('woocommerce_after_checkout_validation', 'gift_custom_field_validation', 20, 2 );
function gift_custom_field_validation( $data, $errors ) 
    // Validating that "Gift" is not empty when selected
    if( isset($_POST['gift_msg']) && isset($_POST['gift']) && empty($_POST['gift']) )
        $errors->add( 'gift', __( "You've chosen to send this as a gift, but did not submit a recipient email address.", "woocommerce" ) );

    // Validating that "Gift" imputed email is different from billing email
    if ( isset($_POST['gift']) && $data['billing_email'] === $_POST['gift'] ) 
        $errors->add( 'gift', __( "To send as gift, you cannot send it to yourself. That's the point of a gift, isn't it?", "woocommerce" ) );
    

代码进入您的活动子主题（活动主题）的 function.php 文件中。经过测试并且可以工作。
