proper mvc way of posting data to a form.

[eluser]chubbypama[/eluser]
hi there. i have a web app i'm trying to rewrite the mvc way using code igniter.
i have a page called "saveData.php" which is called with 3 values passed in the querystring.

eg) saveData.php?val1=abc&val2=1&val3=dfd

I'm trying to create a new controller called "remoteClients" and it has a method called saveStatus.
but i'm not sure how to accept the 3 pieces of data.
i did notice in the code igniter documentation that you can still use querystring to pass data... but i'm wondering what other ways i can accomplish this / what is the recommended way.

thank you.
