After I have filtered with class and subject, it shows a list of the questions.
I want my Shuffle button to work in a way that once I click on it , it automatically reshuffles and select the questions randomly from the database.
So why not using
ORDER BY RAND()
the way you used it in the first request?Another way could be to use the shuffle() method in PHP after you've requested your data from the database.
In any case, if you want the shuffle to be dynamic you'll have to use Ajax, maybe with jQuery's .ajax() method it'll be easier
