WooCommerce: Add Order Notes to WooCommerce PDF Invoices
I use the “WooCommerce PDF Invoices & Packing Slips” plugin, available on the WP Repository, to invoice my clients. At times, for accounting purposes, I need to show the VAT/TAX ID of the client on the PDF invoice.
So, I open the order via WooCommerce > Orders, open the order I want to edit, add a “Note to the Customer” from the right hand side… and then have the following snippet in my functions.php adding such information on the PDF invoice!
You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"
Does this snippet (still) work?
Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.
