You can pass information between pages in several different ways... here's an example:

Your link: http://example.com/controller/method/id/15

$uri = $this->uri->uri_to_assoc();
$this->load->model('model');
$this->model->handleInput($uri['id']);

The above code will pass the id in the URL to the model method handleInput. Let's say your URL looks like this: http://example.com/controller/method/15 - assuming the ID segment in the URL is always in the same place, that is, after the controller and the method, you can retrieve it like this:

$id = $this->uri->segment(3);
$this->load->model('model');
$this->model->handleInput($id);

You can also pass data using the post method. You can retrieve safe post values using the post function, like this:

$id = $this->input->post('id');
$this->load->model('model');
$this->model->handleInput($id);
