php – Custom field fetch error on woocommerce pdf invoice
I want to do some modifications to a template of WooCommerce, but I’m rather ZERO in PHP, so that is why I’m asking some guidance so I could perform my small modifications, which I’m sure are not too difficult.
So I have a plugin which generates me a PDF document from an invoice template, that invoice template is in PHP, so I need an extra field to that template.
There is an error while fetching Custom field of loyal_card.
