It is possible by setting $config['enable_query_strings'] = TRUE;
in your config.php file (As DamienL answered). I just tried with a fresh CodeIgniter installation from here.
However, it appears there must be at least 2 variables (separated with a "&") for it to work.
Here are the steps I took to make this happen:
In config.php, I changed $config['base_url']
to the appropriate directory and set $config['enable_query_strings'] = TRUE;
In the controllers directory I created the following class:
class Testing extends Controller {
function Testing()
{
parent::Controller();
}
function index()
{
$this->load->view('welcome_message');
}
}
/* End of file testing.php */
/* Location: ./system/application/controllers/testing.php */
I can then access the index function with a query string, but only if there are 2 or more variables like this:
localhost/CodeIgniter_1.7-1.2/index.php/testing/index?id=123&cat=abc
If you absolutely need both the segment-based and query string-based approaches, but only need one variable in a particular query string, I suppose you could add a second "dummy" variable and just ignore it.
