Add order customer note to YITH Woocommerce PDF In

Question

In Woocommerce I am using a plugin called YITH WooCommerce PDF Invoice and Shipping List and I would like to add customer note to the PDF invoice.

I would like to add it after the first span line in the code below:

        <span class="notes-title"><?php _e( "Notes", "yith-woocommerce-pdf-invoice" ); ?></span>    
        <div class="notes">
            <span><?php echo nl2br( $notes ); ?></span>
            <?php do_action( 'yith_ywpi_after_document_notes', $document );?>
        </div>
    </div>
    <?php

But i can't figure out how to get the customer note from $document variable.

I have tried to use this answer thread: "Display Customer order comments (customer note) in Woocommerce" which looks pretty much like the same problem but still could'nt figure it out as $document->order->customer_message; doesn't work.

Any help is appreciated.

Answer 1

Since Woocommerce 3 you can't access anymore properties From the WC_Order object. You need to use the WC_Order method [get_customer_note()][1].

So from the $document (YITH global object) you will use:

$document->order->get_customer_note();

To add customer notes to YITH invoice you can choose between 2 ways:

1) Using the available yith_ywpi_after_document_notes action hook:

add_action( 'yith_ywpi_invoice_template_products_list', 'add_customer_notes_after_document_notes', 5 );
function add_customer_notes_after_document_notes( $document ) {
    ?><span><?php echo $document->order->get_customer_note(); ?></span><?php
}

Code goes in function.php file of your active child theme (or active theme). Untested (as I dont have the premium version of the plugin) but it should work normally (depending on the plugin settings).

2) Overriding templates (in your provided code):

    <span class="notes-title"><?php _e( "Notes", "yith-woocommerce-pdf-invoice" ); ?></span>    
    <div class="notes">
        <span><?php echo nl2br( $notes ); ?></span>
        <span><?php echo $document->order->get_customer_note(); ?></span>
        <?php do_action( 'yith_ywpi_after_document_notes', $document );?>
    </div>
</div>
<?php

It should work.

For the free plugin version

• There is no available hooks (like in the provided code)…
• The YITH PDF global object need to be called and it's not $document.

So you will be able to use the following code in templates/invoice/invoice-footer.php template:

 <?php global $ywpi_document; echo $ywpi_document->order->get_customer_note(); ?>
