WooCommerce 结帐自定义字段条件验证

Question

我想将我的自定义字段保存到新的用户元数据中。 我的自定义字段 = T.C.金利克没有

代码行开头的函数用于将字段添加到成员资格部分。

当涉及到注册用户的结帐页面时，我想做的主要事情是自动拉出我在顶部控制的自定义区域

根据你的其他问题回答Save WooCommerce checkout custom field as user meta data，解决了将字段数据保存为用户元数据和订单元数据。

现在您将使用字段验证：

function is_billing_identifier_valid( $tc ){
    if (strlen($tc) < 11 || $tc[0] == '0') 
        return false;
    
    $plus  = ($tc[0] + $tc[2] + $tc[4] + $tc[6] + $tc[8]) * 7;
    $minus = $plus - ($tc[1] + $tc[3] + $tc[5] + $tc[7]);
    $all   = ''; 
    
    if ( $minus % 10 != $tc[9])
        return false;
    
    for ($i = 0 ; $i < 10 ; $i++) 
        $all += $tc[$i];
    
    return $all % 10 != $tc[10] ? false : true;
}

add_action('woocommerce_checkout_process', 'custom_checkout_field_validation');
function custom_checkout_field_validation() {
    if( isset($_POST['billing_identifier']) && ! is_billing_identifier_valid( esc_attr($_POST['billing_identifier']) ) ) {
        wc_add_notice( __( 'Lütfen Geçerli TC Kimlik No Girin.' ), 'error' );
    }
}

代码位于活动子主题（或活动主题）的functions.php 文件中。它应该可以工作。
