How to get 'id' from URL?

[eluser]tahakirmani[/eluser]
Hi

I am trying to get 'id' from URL in order to delete that specific selected product. I have used $this->uri->segment(3) but its not getting any value from URL. Although i can see the 'product_id' in my URL.
If i used $this->url->segment(2) it gives me the second value form URL, but i am unable to get product Id.
Following is my code. Kindly guide me.

Code:

//VIEW
        echo "<a href='delete_controller?product_id=$product_id'>";
        echo $name;
        echo "</a>";

The following URL is generating when i click on $name.

Code:

http://localhost/designs2/index.php/products_controller/delete_controller?product_id=70

Code:

public function delete_controller()
        {
            echo $product_id =$this->uri->segment(3);          
            echo "Taha";
            $this->load->view('delete_confirmation');
        }

Thanks,
Taha

Code:

class Example extends CI_Controller {

    public function example_deletion($id) {
        //deletion code... and whatever you want
    }

}

Then you access it like:
yourdomain.com/example/example_deletion/$id,
if you had more arguments in your method, it would look like
yourdomain.com/controller/method/$arg1/$arg2/... etc.,
but if you wanna keep it with GET approach you access it via

Code:

$this->input->get('name_of_your_get_value');

or use CI uri_segment method

Sorry, newbie question, am I right in thinking you have to setup the routing accordingly for this to work? What would the routing rule look like? Would it be this?:

Code:

$route['example/example_deletion/(:any)'] = 'example/example_deletion/$1';

You could setup other route if you want in routes.php, but by default codeigniter urls looks like this:
base_url/controller/method/param1/param2/.../
this means that your example doesnt need any entries in routes.php
