After searching through the forums and wiki for a simple way to handle query strings in CI, I ended up writing a simple helper. I only needed to receive a query string on one page, so I didn't want to have to enable hooks, change uri_protocol or anything. This is good for cases where you need to get query strings on a page or two, like a search page or confirmations from payment gateways.
Anyway, here's a simple way to access the query string from any controller:
Code:
// for example, we're calling foo.com/search/?term=foo&bar=goo&baz;
$this->load->helper('query');
$qs = new Query_String();
$term = $qs->variable("term"); // returns foo
$bar = $qs->variable("bar"); // returns goo
$baz = $qs->variable("baz"); // returns true
$gaz = $qs->variable("gaz"); // returns NULL
$qsarray = $qs->all(); // returns Array([term] => foo, [bar] => goo, [baz] => NULL)I tried to follow CI Input class conventions of returning null for variables that do not exist. I also return true if a var is provided with no value.
Download the helper to application/helpers and you're ready to go.
I adapted a loop from Dan Horrigan's CodeIgniter Query String hook to look for the query string in a few places.
Corrections and suggestions are very welcome.

Congrats, I'll point a friend of mine to it, he was fighting with this and hacked something up to work with Twitter oAuth... should be interesting to see his comparison.

$this->input->get() is not working for you?

Nope, it doesn't work on Windows/Apache or CentOS/Apache for me.

I had the same problem.
Thing is that Input library is destroying $_GET array when enable_query_strings is set to false and that is the case with standard CI configuration.
If you want to use $this->input->get() and $this->input->get_post() you can extend Input library with this code:
Code:
class MY_Input extends CI_Input {
function MY_Input()
{
$CFG =& load_class('Config');
// Remeber old setting
$tmp = $CFG->item('enable_query_strings');
// Set the enable_query_string to true so Input lib will not destroy $_GET array
$CFG->set_item('enable_query_strings', TRUE);
// In this special case we need to manualy parse the get query
// (when using htaccess to hide index.php on some hosts)
if ($CFG->item('index_page') == '' && $CFG->item('uri_protocol') == 'QUERY_STRING') {
$get_array = array();
parse_str(parse_url($_SERVER['REQUEST_URI'], PHP_URL_QUERY), $get_array);
$_GET = $get_array;
}
// Initialize Input library
parent::CI_Input();
// Set the old setting back
$CFG->set_item('enable_query_strings', $tmp);
}
}
