Best way to do this?

Hi everybody,

I've just started using codeigniter, and everything has been good so far, but now I'm stuck on this.

I'm writing a simple search function, and I want the url's to look like this
http://localhost/index.php/controller/se...arch+Terms

So that they're easy to read and people can bookmark the search results.

Right now I have it partially working using 3 function

Code:

function index()
    {
        $this->load->view('form_view');
    }
    
    function search_redirect()
    {
        $search_string = $this->input->post('search');
        redirect('/reader/search/'.urlencode($search_string));
    }
    
    function search()
    {
        //search code
    }

And it works okay, the problem is that as soon as I add spaces to the search I get this:

An Error Was Encountered
The URI you submitted has disallowed characters.

I was wondering what the best solution is?

So far the only thing I have thought of would be to set $config['permitted_uri_chars'] to nothing, but the config file has a warning:

Leave blank to allow all characters -- but only if you are insane

I was wondering, what would be the problem with that?
