在注册字段中，我引入了另外两个字段，分别使用注册用户的名字和姓氏。在我的woocommerce功能中。php我定义（user\\u firstname/lastname）如下：

function woocommerce_process_registration() {
global $woocommerce, $current_user;

if ( ! empty( $_POST[\'register\'] ) ) {

    $woocommerce->verify_nonce( \'register\' );

    // Get fields
    $user_email = isset( $_POST[\'email\'] ) ? trim( $_POST[\'email\'] ) : \'\';
    $password   = isset( $_POST[\'password\'] ) ? trim( $_POST[\'password\'] ) : \'\';
    $password2  = isset( $_POST[\'password2\'] ) ? trim( $_POST[\'password2\'] ) : \'\';
    $user_email = apply_filters( \'user_registration_email\', $user_email );
    $user_firstname = isset( $_POST[\'firstname\'] ) ? trim( $_POST[\'firstname\'] ) : \'\';
    $user_lastname = isset( $_POST[\'lastname\'] ) ? trim( $_POST[\'lastname\'] ) : \'\';

也就是说，我如何在标题中添加欢迎消息。使用该格式的php，

<?php global $user_identity;
get_currentuserinfo();

if ($user_identity == \'\') {
echo(\'Welcome Guest\');
} else {
echo(\'Welcome \' . $user_identity);
}
?>

提前感谢！

if ( is_user_logged_in() ) {
    $current_user = wp_get_current_user();
    echo \'Welcome, \' . $current_user->user_firstname . \'!\';
} else {
    echo \'Welcome, visitor!\';
}
