在 WooCommerce 帐户激活邮件中访问用户的名字（DOI 通过 WooCommerce Germanized）

Question

我们的 WooCommerce 网站有一个自定义注册页面，该页面基于 Business Bloomer 短代码，并为用户的名字添加了一个输入字段。我们的functions.php 中的代码如下所示：

// THIS WILL CREATE A NEW SHORTCODE: [wc_reg_form_bbloomer]

由于我们的网站位于德国，因此我们使用具有 DOI（双重选择加入）功能的 WooCommerce 德国化插件。因此，用户会收到一封激活邮件，他们必须点击该邮件才能激活帐户。在激活邮件中，我们希望有更个性化的感觉，因此包含用户的名字。在那里，我们将来自 WooCommerce Germanized 的原始电子邮件模板添加到我们的子主题中。

问题是我可以访问的唯一值（显示在实际发送的电子邮件中）是 $user_login，它返回自动创建的用户名。如何访问保存为名字和帐单名字的用户的名字。我们子主题中的模板如下所示：

<?php
/**
 * Customer new account activation email.
 *
 * @see https://github.com/vendidero/woocommerce-germanized/wiki/Overriding-Germanized-Templates
 * @package Germanized/Templates
 * @version 1.6.4
 */
if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

?>

<?php do_action( 'woocommerce_email_header', $email_heading, $email ); ?>

    <p><?php printf( __( 'Hi %s,', 'woocommerce' ), esc_html( $user_login ) ); ?></p>

    <p><?php printf( __( "Thanks for creating an account on %s. Please follow the activation link to activate your account:", 'woocommerce-germanized' ), esc_html( $blogname ) ); ?></p>

    <p><a class="wc-button button"
          href="<?php echo esc_url( $user_activation_url ); ?>"><?php _e( 'Activate your account', 'woocommerce-germanized' ); ?></a>
    </p>

<?php if ( get_option( 'woocommerce_registration_generate_password' ) == 'yes' && $password_generated ) : ?>

    <p><?php printf( __( "Your password has been automatically generated: <strong>%s</strong>", 'woocommerce-germanized' ), esc_html( $user_pass ) ); ?></p>

<?php endif; ?>

    <p style="font-size:75%;"><?php printf( __( "If you haven't created an account on %s please ignore this email.", "woocommerce-germanized" ), esc_html( $blogname ) ); ?></p>

    <p style="font-size:75%;"><?php printf( __( 'If you cannot follow the link above please copy this url and paste it to your browser bar: %s', 'woocommerce-germanized' ), esc_url( $user_activation_url ) ); ?></p>

<?php
/**
 * Show user-defined additional content - this is set in each email's settings.
 */
if ( $additional_content ) {
    echo wp_kses_post( wpautop( wptexturize( $additional_content ) ) );
}
?>

<?php do_action( 'woocommerce_email_footer', $email ); ?>

我已经尝试按照此处所述填充名字（https://wordpress.org/support/topic/new-account-email-insert-first-name/）并通过 $user->display_name 访问它，但这确实不行。

我还尝试了此处提供的解决方案（从 Woocommerce 中的 woocommerce_created_customer 钩子获取用户元数据）通过 Customer 对象访问名字。代码如下所示。我也没工作。

<p><?php $customer = new WC_Customer( $customer_id ); printf( __( 'Hi %s,', 'woocommerce' ), esc_html( $customer->get_first_name() ) ); ?></p>

任何帮助将不胜感激！

Answer 1

首先你需要找到用户。我假设您无权访问用户 ID，如果可以，您可以跳过第一行，并在适当的位置插入 user_id。

然后您需要从元数据中获取名字。根据您的代码，您将其存储在元数据字段中'billing_first_name'。然后就是将它插入到您的电子邮件中。

<?php 

$the_user = get_user_by('login', $user_login);
$first_name = get_user_meta($the_user->ID, 'billing_first_name', true);

?>
<p><?php printf( __( 'Hi %s,', 'woocommerce' ), esc_html( $first_name ) ); ?></p>
