Access first name of user in WooCommerce account acitivation mail (DOI via WooCommerce Germanized)

Question

We have a custom registration page for our WooCommerce site which is based on a Business Bloomer shortcode and added an input field for the first name of the user. The code within our functions.php looks like this:

/**

 */

// THIS WILL CREATE A NEW SHORTCODE: [wc_reg_form_bbloomer]
add_shortcode('wc_reg_form_bbloomer', 'bbloomer_separate_registration_form');

function bbloomer_separate_registration_form()
{
    if (is_admin()) return;
    if (is_user_logged_in()) return;
    ob_start();

    // NOTE: THE FOLLOWING <FORM></FORM> IS COPIED FROM woocommerce\templates\myaccount\form-login.php

Since our site is based in Germany we use the WooCommerce Germanized plugin with the DOI (double opt-in) functionality. So a user receives an activation mail which they have to click in order to active the account. Within the activation mail we want to have a more personal feeling, thus include the first name of the user. There we added the original email template from WooCommerce Germanized to our child theme.

The problem is that the only value I can access (is displayed in the actually delivered email) is $user_login which returns the automatically created username. How can I access the first name of the user which is saved as first name and billing first name. The template within our child theme looks like this:

<?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 ); ?>

I already tried to populate the first name as described here (https://wordpress.org/support/topic/new-account-email-insert-first-name/) and to access it via $user->display_name but this did not work.

I also tried the solution provided here (Get user meta data from woocommerce_created_customer hook in Woocommerce) to access first name via Customer object. The code would then look like below. I didn't work either.

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

Any help would be highly appreciated!

Answer 1

First you need to find the user. I assume you don't have access to the user ID, if you do you can skip the first line, and insert the user_id at the appropriate point.

Then you need to get the first name from the meta data. According to your code you store it in the metadata field 'billing_first_name'. And then it's a matter of inserting it in your email.

<?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>
