Add notes to packing slip

Hi @flostone,

Do you want to display the same note in all your packing slips, or do you want to add different notes in each order?

If the first, you can achieve it with this code snippet:

/**
 * WooCommerce PDF Invoices & Packing Slips:
 * Displays a custom note in all the PDF packing slips
 */
add_action( 'wpo_wcpdf_after_customer_notes', function( $document_type, $order ){
	if ( $document_type == 'packing-slip' ) {
		echo '<h3>Important:</h3>';
		echo 'Your custom notes goes here!';
	}
}, 10, 2 );

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

In the case that you want to add a different note for each order, first you’ll need to add an order custom field (Advanced Custom Fields is the best plugin I know to do this), and then you can display your custom notes for each order with this code snippet:

/**
 * WooCommerce PDF Invoices & Packing Slips:
 * Displays a custom note in the PDF packing slips
 */
add_action( 'wpo_wcpdf_after_customer_notes', function( $document_type, $order ){
	if ( $document_type == 'packing-slip' && ( $custom_note = $order->get_meta( 'custom_note' ) ) ) {
		echo '<h3>Important:</h3>';
		echo $custom_note;
	}
}, 10, 2 );

Yes, this can be also possible! You have two options to do this:

1. By adding a custom block to the packing slip with the customizer, included in Premium Templates, using the {{invoice_notes}} placeholder, like this:

   

2. Or with some PHP code through a code snippet like this:

   /**
    * WooCommerce PDF Invoices & Packing Slips:
    * Show the invoice notes on packing slips too
    */
   add_action( 'wpo_wcpdf_before_customer_notes', function( $document_type, $order ) {
       if ( $document_type == 'packing-slip' ) {
           $document = wcpdf_get_document( 'invoice', $order );
           if ( $document && $document->exists() ) {
               ?>
               <div class="notes">
                   <h3>Notes:</h3>
                   <?php echo $document->document_notes(); ?>
               </div>
               <?php
           }
       }
   }, 10, 2 );

In brief, if you have a child theme, you can add code snippets in its functions.php file: don’t add code snippets to the functions.php file from your parent theme, because you may lose your customizations after updating your parent theme! The another way to add code snippets, that is safer in my humble opinion, is to use the Code Snippets plugin: This plugin stores the code snippets in your database, so you don’t have to worry about losing your customizations after updating your plugins or theme 😉

I’m glad to hear that, @flostone!
