So, I worked out the hack for it based on the PayPal dev guide.
https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/Appx_websitestandard_htmlvariables/
Add “t3” and “p3” rows to the (whatever)_options_meta DB where:
– product_id matches the recurring product
– t3 value in the “name” column signifying the subscription payment cycle unit of time. “value” column should be one of the following:
D — for days; allowable range for p3 is 1 to 90
W — for weeks; allowable range for p3 is 1 to 52
M — for months; allowable range for p3 is 1 to 24
Y — for years; allowable range for p3 is 1 to 5
– AND another row with p3 in the “name” column and a “value” within the allowable range for the corresponding t3 selection above.
This is a lot of work for a feature that the developer is selling as working.
