Adding order fee to PDF

Hi guys,

First of all, I’m not a professional back-end coder. Although I have some knowledge about coding.

What I’m trying to do is add the order fees into a pdf invoice creator. I’ve been struggling for a few days to get this done now. I’m working with yith pdf invoice.

What I have so far;

Top of the document: <?php global $ywpi_document, $woocommerce; ?>

——–

<?php $order = new WC_Order( $order_id );
$order_fees = $order->get_fees(); ?>

<tr>
<td class=”column-product”><?php _e( “Paypal fees” ); ?></td>
<td class=”column-total”><?php var_dump($order_fees); ?></td>
</tr>

——–

The html is showing up like I expect it to, but the value is not showing up.

What is the problem here?

Thank you!
