问题:

i was wondering whats the best way to route to pages in codeigniter? Say for example user wants to route to the index page, but should i create a method in a controller that just fo rthat page, or what is better way?

回答1:

No need to create separate methods or controllers. Here's how I do it:

class Pages extends CI_Controller {

    function _remap($method)
    {
        is_file(APPPATH.'views/pages/'.$method.'.php') OR show_404();
        $this->load->view("pages/$method");
    }

}

So the url http://example.com/pages/about would load the view file application/views/pages/about.php. If the file doesn't exist, it shows a 404.

You don't need any special routing to do this, but you can do something like this if you wanted the URL to be http://example.com/about instead:

// Route the "about" page
$route['about'] = "pages/$1";

// Route ALL requests to the static page handler
$route['(:any)'] = "pages/$1";

回答2:

Routing can be done using the application/config/routes.php file. You can define custom routes redirecting to the index page there. There is absolutly no need to create methods for every page.

A more detailed explanation can be found here: http://codeigniter.com/user_guide/general/routing.html

EDIT: Didn't realy got what you meant, but here is the solution I use:

class Static_pages extends CI_Controller {

    public function show_page($page = 'index')
    {
        if ( ! file_exists('application/views/static_pages/'.$page.'.php'))
            show_404();

        $this->load->view('templates/header');
        $this->load->view('static_pages/'.$page);
        $this->load->view('templates/footer');
    }

}

I make 1 controller in application/controllers for the static pages with 1 method in it that I use to load in the static pages.

Then I add this line to application/config/routes.php:

$route['(:any)'] = 'static_pages/show_page/$1';
//you can also change the default_controller to show this static page controller
$route['default_controller'] = 'static_pages/show_page';
