I am a total noob in programming so pls be patient with me. My question might look stupid to you.
I have here a query string:
http://localhost/exercises/php_js/exer_test/?year_list=1994&event_list=Singing+Contest&btn_show=Show
I think the &btn_show=Show has something to do with the value of the submit element. Is there a way that I can remove or hide that in the Query string or URL?
