filter data by URI (newbie question)

[eluser]Rick Blackdog[/eluser]
Hi, just getting to grips with CI, love it so far.

I've been able to do CRUD stuff with my data but something I haven't been able to do is displaying the data on a page from a specific record as per the URI. What's the best way of doing this?

Thanks for the help

The easiest way is to use the records id. For example if you have a blog and want to show blog post depending on the id, you would have link something like this:
http://yourblog.com/blog/view_post/2

That means that you have a controller called a blog with method "view_post". 2 would be the parameter to view_post. The controller would be something like this:

Code:

class Blog extends Controller {

    function __construct()
    {
        parent::__construct();
        
        // Youll probably use blog_model from every method from this controller so lets load it in contructor
        $this->load->model('blog_model');
    }
    
    function view_post($id = FALSE)
    {
        // If no id has not been passed via url, just return false(stop execution of this method here)
        if (!$id)
        {
            return FALSE;
        }
        
        $data['post'] $this->blog_model->get_post($id);
        
        $this->load->view('blog/view_post',$data);
    }

Model blog_model would have that get_post($id) method where you grab the post depending on the $id and pass finally pass it to the view with $data.
