Query Strings are a total turn off to CodeIgniter - El Forum - 05-27-2008

I have spent days trying to just send some variables to the page I am at. It would be really nice if there was a good tutorial on how you do this as this seems to be the method that you think is best.
For example I go to the page:
http://domain.com/page/
Now I want send a variable but I always get a 404 page not found:
http://domain.com/page/variable
This is how my code looks:
class Welcome extends Controller {
function Welcome()
{
parent::Controller();
}
function index()
{
$product_id = $this->uri->segment(2);
$this->load->view('header');
$this->load->view('welcome');
$this->load->view('footer');
}

I believe you're getting a 404 because if there is anything after the controller name in the query string (in your case, the thing after is "variable") it assumes it's a function of that controller. So it's looking for a function named variable and freaking out because there's not one.
Read the URL section of the user guide for more info: http://ellislab.com/codeigniter/user-guide/general/urls.html
Try linking to http://domain.com/page/index/variable instead, and change your uri call from "segment(2)" to "segment(3)". That should do it.

Finally!
I didn't get that you had to pass the function first in the segment and then variable.
Thanks so much.

No problem. Welcome to CI!

you don't have to use url segment if you don't want to either
Code:
function index($product_id)
{
...will achieve the same thing.

I like that! What if no param is passed, could you change $product_id into $product_id=null in the function declaration to handle either case?
I'm still a CI newbie too!

yes you can default the parameter(s) like you suggest.
Code:
function index($product_id=NULL,$somthing_else=2,$and_another='tree')
{
