Getting variable from uri into controller, then model, then view

[eluser]ToddyBoy[/eluser]
After reading more about URI segments, I changed the controller to this.

Code:

function edit_listing()
{
    $id = $this->uri->segment(4);
    $this->load->model('lms/listings_model');
    $data['detail'] = $this->listings_model->edit($id);
    $this->load->view('lms/edit_listing', $data);
}

I didn't think I had to explicitly assign the URI segment to a variable to use it in the model. I thought that if I put a variable name when calling the function, it can be used.

Doesn't matter. The main thing is, it works and my head can now start to heal.
