How to Implement Dynamic Routing from Database in CodeIgniter 4-CodePudding

As I have mentioned, may you please help me to implement dynamic routing from the database in CodeIgniter 4 ? I have implemented a blog where all blog posts store in the posts table. The table has the slug column which is used to fetch a blog.

Site pages will be look like:

www.mysite.com/how-to-work-with-ci

www.mysite.com/your-health-your-wealth

As, we have already implemented such features in Codeigniter 3, but I did not found anything equivalent in CI4.

Please help me regarding this. Please let me know if you want any other info regarding this from me, thanks...

It's actually quite easy. First, you will need to configure the routes as follow in routes files :

$routes->get('blogs/(:any)', 'BlogController::show/$1');

Here (:any) is a placeholder (slug) for the dynamic route which will be passed to your controller.

In your BlogController, you will need to fetch the value passed to this parameter.

show($slug){
... switch($slug)
}

You can also refer to the following for better of the routes in CI4.

Try this:

// app\Config\Routes.php

$routes->get('/', 'Home::index');
$routes->addPlaceholder('admin', 'admin');
$routes->addPlaceholder('pub', '[a-z] ');

$routes->get('(:admin)', 'Home::$1');
$routes->get('(:admin)/(:any)', 'Home::$1/$2'); // remember $1 = admin

$routes->get('(:pub)', 'Home::index/$1'); // you can use (:any)

// app\Controllers\Home.php

<?php

namespace App\Controllers;

class Home extends BaseController
{
    public function index($slug = 'home')
    {
        echo 'INDEX: ' . $slug;
    }

    public function admin($page = 'main admin')
    {
        echo 'ADMIN: ' . $page;
    }
}
