1.2 Folder wp-content/signatures

To protect the access of the customer's signature, I create a folder wp-content/signatures where all signatures will be saved.

1.3 PDF

• In the table _templates there is the list of templates. To change the PDF template, it is important to create new row in DB and update the id of "_genpdf_id_current_template_pdf" option. Never modify the current HTML of the DB table.
• Some dynamic fields of PDF are from customer data, and some from the product; therefore, by ACF in the admin panel, I created new fields of the product. For the same reason, after the order creation, the plugin saves product metadata into the wc_orders_meta linked to the order_id. In this way, we can guarantee the correct data in case the product is updated in the future.
• In the order list, there are buttons to download a PDF or send an email to the customer with attachments
• After each order with successful payments, the customer will receive an email with all attachments.
• To generate the PDF, I use Dompdf, unfortunately, I commit the vendor folder beacuse I don't have control over the website hosting. Usually the folder vendor is never committed, only the composer.json and composer.lock.
