Add custom fields | WordPress.org

Hi @magick207:

You have used conf_info_bdg_affil not only as a meta key, but also as a method, that is a class function that do not actually exists within the code base.

That said, please try with this code snippet instead:

<tr class="custom-field">
<th><?php _e( 'Custom field:', 'woocommerce-pdf-invoices-packing-slips' ); ?></th>
<td><?php $this->custom_field( 'conf_info_bdg_affil' ); ?></td>
</tr>
