Display Invoice number in Packing Slip

Hey @bparker41,

Once you’ve made sure the corresponding Invoice Number exists, what happens when you try tihs?
echo $this->order->get_meta('_wcpdf_invoice_number');


The result below is using…
echo $order->get_meta('_wcpdf_invoice_number');
…via code snippet:

The Invoice number does get pulled into the Invoice Template when generating the PDF. Are you saying to replace that string with this one in our Packing Slip Template: https://app.screencast.com/aoONJvJErylne

@bparker41,

I was using a code snippet. ??

So if you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide:?How to use filters

add_action( 'wpo_wcpdf_before_order_data', 'wpo_wcpdf_display_invoice_number_in_packing_slip', 10, 2 );
function wpo_wcpdf_display_invoice_number_in_packing_slip( $document_type, $order ) {
	if ( empty( $order ) ) { return; }
	if ( $document_type == 'packing-slip' ) {
		?>
			<tr class="invoice-number">
				<th>Invoice Number: </th>
				<td><?php echo $order->get_meta('_wcpdf_invoice_number'); ?></td>
			</tr>
		<?php
	}	
}

Thank you. I did miss the line where you mentioned it was a Code Snippet and was trying to edit our template. That Snippet did work.
