How to: display the full $_GET in the current page URL on form submit

Hey all,

I have a form, when a user presses enter on a typed/chosen selection from a form input I then store that to an array, and so I can display this as tags below the form input.

What I’d like to do is improve the way a user can go back to a search and save a search, the best way to do this will be with the page URL using queries.

E.g. example.com/?title=engineer|sotware developer|java developer&qualification=bachelor

What I’m not sure how to do, is as the user stores each value in the array - then change the URL query instantly. Any ideas?
