Add order customer note to YITH Woocommerce PDF Invoice

问题

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.

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(); ?>
