Question posted in 
I wrote a little plugin that adds a couple of custom fields on checkout page. The fields are related to B2B buyers so they can input Company name, license number and address.
Everything pretty much works fine, except the values are not being displayed in order emails, most importantly, order completed email.
Here is the part of code I’m having trouble with
add_filter('woocommerce_email_order_meta_fields', 'mx_woocommerce_email_order_meta_fields');
function mx_woocommerce_email_order_meta_fields( $fields ) {
if (isset($_POST['r1_checkbox']) && !empty($_POST['r1_checkbox'])) {
echo '<h2>R1 račun za kupca</h2>';
$fields[] = 'Ime tvrtke';
$fields[] = 'Adresa tvrtke';
$fields[] = 'OIB tvrtke';
return $fields;
}
}
Can’t figure out what is wrong. I also tried using $keys instead of $fields but that didn’t help.
UPDATE (full code):
/**
* Let's add our new fields to the checkout
*/
add_action( 'woocommerce_after_checkout_billing_form', 'mx_custom_checkout_field' );
function mx_custom_checkout_field( $checkout ) {
echo '<div id="mx_custom_checkout_field"><h3>' . __( 'Pravne osobe' ) . '</h3><p style="margin: 0 0 5px;">Trebate li R1 račun?</p>';
woocommerce_form_field( 'r1_checkbox', array(
'type' => 'checkbox',
'class' => array( 'r1-checkbox form-row-wide' ),
'label' => __( 'Da' ),
), $checkout->get_value( 'r1_checkbox' ) );
woocommerce_form_field( 'r1_ime_tvrtke', array(
'type' => 'text',
'class' => array( 'r1-text form-row-wide' ),

else print '-';
}
}
Note that r1_checkbox is just a checkbox that toggles 3 fields under it.

Your code has some little mistakes here and there, I’ve revised it
I also changed a deprecated hook:
woocommerce_email_order_meta_keyswoocommerce_email_order_meta_fieldsReplaced by a much appropriated hook:
woocommerce_checkout_update_order_metawoocommerce_checkout_create_orderThere are some mistakes in your function code. To make it work, use the following:
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
