I've been asked by some of the editors on dawiki of the possibilities
to create a set of questions that can lead to the correct image
license(s) for image uploads. Furthermore, there is a request for
enforcing a name for the photographer, so proper crediting can be
Looking at SpecialUpload.php, there are no hooks that is really
suitable for this, and also I'm a little unsure about any effects of
beginning to send people to new pages mid-upload, which would happen
if added to any of the two existing hooks.
So I propose to add two hooks: One for adding fields to the initial
form, and one for validating the contents before proceeding with the
upload. Is there any reason that validation of license information
should not be done in this way? Also, if a more suitable way of
"quizzing" people exists, I'd be happy to hear about that.
