I found something regarding the database:
qa_pregpages--> VALUES (4, 'daily', '_', 1, 0, 'daily', '', '470');
There the number of the daily page (470 here) is stored.
I as well found the function to get the content of the pages:
qa_db_page_full_selectspec($slugorpageid, $ispageid)
But I cant write the function to get the questionnumber into a variable.
Shouldnt be so complicated, but i am still a beginner. Someone ? Thank You so much.
