Ahh, okay. #2 works fine, IF you know where to change a 'false' into a 'true'... ;) But really, I just flipped it on, worked right off the bat. Doesn't look anything amazing (not a lot of formatting ability...), but the data is all there.
The main CG-Amazon call, query_amazon, is now 'tucked away' behind show_amazon_items and show_wishlist_items as some folks found it a bit too tricky. Unfortunately, one of the things I 'lost' in that transition was passing through an option to enable/disable the extra fields.
So, I guess there's two possible directions. One is to add show/no-show as an extra param to the current 'high level' calls into CGA. The other is to just show the extra fields whenever I'd normally be showing things like Price, etc. The former gives much more control to you, or at least it'll seem that way! ;)
If you want to test it out and aren't TOO shy of PHP, you can go into cg-amazon.php, into whichever of the functions you are calling, and look for the query_amazon call. The third line of passed params looks like:
$style, false, false, false, true,
You want it to look like
$style, false, true, false, true,
If you are calling query_amazon 'old school' direct style, it is param #13 that needs to be true (not false) in order for the extra data fields to be pulled from the array and shown.
I'm still looking/thinking about #1. ;)
