Insert field “billing_number”

Hello @fredperes

Please read this documentation page: Displaying a custom field in a custom template

Hope that helps!

I’ve tried this:

$this->billing_number('billing_number', 'Billing number:')

Got this error:

Fatal error: Call to undefined method WPO\WC\PDF_Invoices\Documents\Invoice::billing_number()
#0 /app/public/wp-content/plugins/woocommerce-pdf-invoices-packing-slips/includes/documents/abstract-wcpdf-order-document.php(742): include()

#7 /app/public/wp-admin/admin-ajax.php(175): do_action('wp_ajax_generat...')
#8 {main}

Thie field is:
<input type=”text” class=”input-text form-control” name=”billing_number” id=”billing_number” placeholder=”” value=””>

Any clues? Thanks!

Hello @fredperes

Try instead this: <?php $this->custom_field('billing_number', 'Billing number:'); ?>

The error is gone. But it’s not displaying the value.

Hi @fredperes

Probably because billing_number is not the correct custom field name. Please read our documentation page: Finding WooCommerce custom fields

Problem solved!

The field is “_billing_number”.

Thanks a lot for your help!

You’re welcome ??
