Remove controller's name from url. Codeigniter - codeigniter

Question

can someone help me with this. I want to remove controller name from the url like this
www.site-name.com/controller_name/controller_functions/controller_arguments
to this
www.site-name.com/controller_arguments
for instance:
www.site-name.com/blog/display/blog-title
to this:
www.site-name.com/blog-title
Below is my controller class
class Blog extends CI_Controller {
public function index() {
$data['blogs_data'] = $this->Blog_model->get_blogs();
$data['main_view'] = "blog/blog_layout";
$this->load->view('layouts/main', $data);
}
public function blog_display($page_url) {
$data['blog_data'] = $this->Blog_model->get_blog($page_url);
$data['main_view'] = "blog/blog_detail_layout";
$this->load->view('layouts/main', $data);
}
}
as your can see from my controller the URL of my site to display blog going to be like this www.website-name.com/blog/blog_display/($page_url) <== whatever the $page_url going to be. Now, what I want is to be like this www.website-name.com/($page_url) <= so straight to the $page_url.
Thanks

Answer 1

Go to application->config->routes.php
Then you can set a route to "blog/display/blog-title" as "blog-title"
Add the below line to your routes.php file
$route['blog-title'] = 'blog/display/blog-title';
You can replace "blog/display/blog-title" to "blog-title" then.

Answer 2

define route in routes.php file.
route['controller_arguments']='controller_name/controller_functions';
on which onclick you are showing this url.define there this.
<a href="<?php echo base_url(); ?>controller_arguments">
</a>

I imagine that your slugs are generated so you can't just write all your slugs into your routes.
In you specific case you need something like this in your routes:
$route['(:any)] = 'blog/display/$1';
Do bare in mind that your routes are used from top to bottom. So if you have this route as your first one the rest of your site might not work.
So in case of a entire blog stucture you might want something like:
$route[''] = 'blog/index'; // For first page without pagination
$route['(:num)] = 'blog/index/$1'; // Blog article pagination (for second page and all other pages)
$route['(:any)] = 'blog/display/$1'; // Blog article detail
To avoid some problems in the future with having a route that is just a (:any) param, you might want to add an extra segment in that blog detail article.
Like so:
$route['detail/(:any)] = 'blog/display/$1'; // Blog article detail
