I have spent some time searching about and it seems like there are still no simple solutions for the situation where one wants to use POST instead of GET and where one wants to supply a value, though there have been dozens of requests along these lines over the past few years. A look in the tracker was exhausting but I found nothing definitive....
SO, I thought I'd post the questions here:
Has a tracker request been made to add the option to link via POST instead of GET; if not is there interest and if so can someone point me to it
and
at present the values are all hard linked via resource.class.php and if a teacher wants to provide a class password to a remote site it would be nice if the teacher could add that value.... (most beneficially on the resource page, but alternatively as a set of extra course fields...) so, is there a tracker request for this feature; and if not is there interest in same and if there is could someone point me to it?
