使用$ _GET变量

Question

I need a little help with using $_GET variables if possible. Right now I am using them to load different parts of my website when needed but I can't figure out how to clear the screen as if a new page were being loaded when the $_GET variable is set. I was wondering if it is possibele.

As an example say I have a sports categories page which lists all the sport available on the website, In the controller I have this piece of code which activates when the user clicks on football in the list of sports:

if (isset($_GET['football'])) 
        {  
            .... 
        }

So at the moment all of the football information is displayed along with all of the category information. Is there a way to remove the category information and just have the sports info there without using javascript?

Any pointers in the right direction would be really appreciated.

Thank You

Assuming that when the user clicks "Football" a new HTTP request is done, then you can have:

if(!isset($_GET["football"])) ... { // Code to display categories }

If you don't have another HTTP request, then you will have to do it with Javascript, hidding the element that contains the category list.

Hope this helps...
