I am using the subscription detail app instance
https://stackideas.com/docs/payplans/administrators/essentials/subscription-detail
I have a select box here with a name of po_required which is either 1,2 or 3 as a value
I need to check this value in my pdfinvoice view so need to know how I can call this value from the database so I can do a PHP if statement based on the value of this field. As this is an app instance, I assume its not part of PayplansApi::getSubscription($id), so what can I use to call this value in my code.. if at all?
The data is stored in #_payplans_subscription.params
