function quiz_views_pre_view in Quiz 6.x

Same name and namespace in other branches

1. 8.6 includes/views/quiz.views.inc \quiz_views_pre_view()
2. 8.5 includes/views/quiz.views.inc \quiz_views_pre_view()
3. 7.5 includes/views/quiz.views.inc \quiz_views_pre_view()

Implements hook_views_pre_view().

Replace the static field with dynamic fields.

@todo this only works on a single quiz, with the first argument being a quiz ID (e.g. quiz/1/results). Should be expanded to make argument configurable.
