The general selectors previously used here matched either form. With
this change, they will only match the form for which the selection was
actually made.
The problem before was that an error in the annual form would prevent
submission of the monthly form and vice-versa. That is herein corrected
with this change, which assures that the input with id of "amount" if
the specific form (id'd with "annual" or "monthly") is the only one
checked.
I actually think I want amount to be id rather than a class, now that I
figured out the proper selector to find them all.
Also, the $("span", input.parent()) was buggy if there were any other
span's other than error-related ones in the supporter-form-inputs div.
Finally, ditch that <small> stuff and simply place a font-size reduction
into the CSS for the form-error-show.
According to
https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/Appx_websitestandard_htmlvariables/
no_shipping has the following values:
0: prompt for an address, but do not require one
1: do not prompt for an address
2: prompt for an address, and require one
The default is 0.
Ideally, any time they change wantGift, even in a pure HTML form, we'd
change it between 0 and 2 as appropriate (i.e., we need the address if
they want the t-shirt).
However, I couldn't find an easy way to make this modification in pure
CSS or HTML, so it only happens in Javascript-enabled browsers.
This is still graceful degradation, since the only impact is in cases
where a non-Javascript user fails to give us an address, and we have to
email later to get the shipping address.
This required some doing. I'm not completely sure it works, but I
roughly followed the tutorial available at:
https://www.paypal.com/webapps/mpp/get-started/create-recurring-donation-button
with back-reference to this:
https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/Appx_websitestandard_htmlvariables/
My main concern with this setup currently is that 'p3' must be set to
'1', which would seem from the documentation to be saying the payment
will recur only once. There is a subtle hint via the tutorial that
setting 'src' to 1 will override 'p3' with whatever is found in 'srt',
but that's not said anywhere explicitly that I can find. So, I'm going
with this and I'll just test it myself with a monthly subscription to
see if it's indefinite (which is the behavior we herein desire).
Finally, note that "amount" is now a class rather than id, since I'm now
using the associated jQuery .on('input') code for both the annual and
monthly amount boxes.
I suspect some supporters are just accepting the default, so by default,
the t-shirt option will be "No", and supporters will have to
affirmatively chose "Yes".
Thanks to previously committed Javascript hack, users with Javascript
capable browsers should avoid seeing the t-shirt sizing options until
they chose "Yes".
Use Javascript to hide the t-shirt size selector when the the user
selects "No" for "Do you want a t-shirt?". Reshow it (and make sure
it's shown by default) for "Yes".
This CSS, which I discovered from extensive research online, should work
to create a bulleted list with the bullets being the heart-shaped
Conservancy logo.
