我一直在尝试编辑WordPress在用户注册我的网站时发送给他们的自动电子邮件。目前，他们注册在一个名为Forminator的插件制作的表单上。然而，WordPress默认的电子邮件仍然会发送，其中包含我的管理员url，这简直没有吸引力。我已经求助于使用代码，因为没有其他插件可以在不完全禁用电子邮件的情况下停止/替换默认WP电子邮件。

我尝试了以下代码，但没有替换默认电子邮件：

if ( !function_exists(\'wp_new_user_notification\') ) :
/**
 * Pluggable - Email login credentials to a newly-registered user
 *
 * A new user registration notification is also sent to admin email.
 *
 * @since 2.0.0
 *
 * @param int    $user_id        User ID.
 * @param string $plaintext_pass Optional. The user\'s plaintext password. Default empty.
 */
function wp_new_user_notification($user_id, $plaintext_pass = \'\'){

    $user = get_userdata($user_id);

    // The blogname option is escaped with esc_html on the way into the database in sanitize_option
    // we want to reverse this for the plain text arena of emails.
    $blogname = wp_specialchars_decode(get_option(\'blogname\'), ENT_QUOTES);

    $message  = sprintf(__(\'New user registration on your site %s:\'), $blogname) . "\\r\\n\\r\\n";
    $message .= sprintf(__(\'Username: %s\'), $user->user_login) . "\\r\\n\\r\\n";
    $message .= sprintf(__(\'E-mail: %s\'), $user->user_email) . "\\r\\n";

    @wp_mail(get_option(\'admin_email\'), sprintf(__(\'[%s] New User Registration\'), $blogname), $message);

    if ( empty($plaintext_pass) )
        return;

    $message  = sprintf(__(\'Hey %s,\'), $user->user_login) . "\\r\\n";
    $message .= sprintf(__(\'Thank you for registering with us! You are officially a Member who just earned the Loyalty Bagde, which grants you 50 Points!\'), $plaintext_pass) . "\\r\\n";
    $message .= sprintf(__(\'Earn more rewards now by purchasing any products!\'), $plaintext_pass) . "\\r\\n";
    $message .= wp_login_url() . "\\r\\n";

    wp_mail($user->user_email, sprintf(__(\'Your Brand New Account at %s\'), $blogname), $message);

}
endif;

这段代码是否有问题，或者我是否使用了错误的钩子？我对编码知之甚少，因此非常感谢您的帮助。

add_filter( \'wp_new_user_notification_email\', \'custom_wp_new_user_notification_email\', 10, 3 );

function custom_wp_new_user_notification_email( $wp_new_user_notification_email, $user, $blogname ) {
   // filter stuff in $wp_new_user_notification_email here
   return $wp_new_user_notification_email;
}
