Display "last name" in template

Hi Paul,
Billing last name is not in the default functions, so you first have to get that from the order meta:

<?php
$billing_last_name = get_post_meta($wpo_wcpdf->export->order->id,'_billing_last_name',true);
if (isset($billing_last_name)) {
	echo $billing_last_name;
}
?>

Of course, you can replace “billing” with “shipping” for the packing slip.

Thank you, Ewout! It works!

To whom it may concern. I tweaked this plugin to show the VAT which is essential in the Italian tax system.
I am using the following plugin to add VAT but I renamed the variable of VAT to campo_cf_piva: https://www.netstarsolution.net/woocommerce-partita-iva-e-codice-fiscale-free/

So I added the following code to the Woocommerce pdf invoices packing slips template:

<div class="recipient-address">Codice fiscale: <?php
$campo_cf_piva = get_post_meta($wpo_wcpdf->export->order->id,'campo_cf_piva',true);
if (isset($campo_cf_piva)) {
	echo $campo_cf_piva;
}
?></div>

I hope I made myself understood.

Hello Rosella,
Thanks for sharing!

Newer versions of the plugin make this much simpler (see the FAQ):

<div class="recipient-address">
<?php $wpo_wcpdf->custom_field('campo_cf_piva', 'Codice fiscale:'); ?>
</div>

For displaying the last name (original question), the code would be:

<?php $wpo_wcpdf->custom_field('_billing_last_name', ''); ?>

Have a great day!
Ewout
