Hi Im looking for something like this, does this do what I think it should do...

Add each attendee records ticket variation to the woocommerce order meta, eg security code and ticket ID

I also have the pdf add on, is there a way of adding this as a field as well (the latter part of the URL which I can append)

Thanks
