ok, a print_r() of $_GET will give you an empty array because CI stores the data from $_GET elsewhere and empties $_GET as explained.
But you should be able to fetch de GET items using $this-input->get('var name');
I tested this just now with this simple function:
Code:
function getitnow() {
echo $this->input->get('data');
}
and when using the url
Code:
mydomain.com/test/getitnow?data=hello%20world
CI echoed 'Hello world' as a result
