Hi, since 2017 we use your plugin and we used this code to include in the invoice a custom field we have in the order ( using the plugin Checkout Field Editor (Checkout Manager) for WooCommerce – WordPress plugin | WordPress.org) …. the code is the following:
// add_filter( 'wpo_wcpdf_billing_address', 'incluir_nif_cif_en_factura' );
function incluir_nif_cif_en_factura( $address ){
global $wpo_wcpdf;
echo $address . '<p>';
$wpo_wcpdf->custom_field( 'billing_nif_cif', 'NIF/CIF: ' );
echo '</p>';
}we update to the last version and the code give us an error on creating the invoice:
Fatal error: Call to a member function custom_field() on null
