Currently, the routes donation/new and donation/add use different parameter names for the amount, some of the names are in German. This has led to confusion and extra code during banner and skin development.
- amount is provided by amount parameter
- English parameters paymentType (=zahlweise), and interval (=periode) are used consistently
- All banners are adapted for the new parameters
- Legacy parameter names
- are still accepted.
- log a notice.
New banners must use the new parameter. If the banner markup has different form field names for selected and "input" amount, the banner code must deal with unifying the amount into one parameter.
