To create a basic route in Yii, first set up a controller by placing it in the controllers directory with proper naming and class definition extending yii\web\Controller. 1) Create an action within the controller by defining a public method starting with "action". 2) Configure URL structure by enabling pretty URLs through urlManager settings in config/web.php. 3) Define custom URL rules when necessary, such as mapping 'post/
To create a basic route in Yii, you need to set up a controller and an action, then configure the URL structure so that it maps correctly. The process is straightforward once you understand how Yii’s routing system works.
Setting Up the Controller
In Yii, controllers are responsible for handling requests and returning responses. To create a new controller, place it in the controllers directory of your application or module. The file name should follow the naming convention: YourControllerName.php.
For example, if you want to create a PostController, the file would be named PostController.php. Inside this file, define a class that extends yii\web\Controller:
namespace app\controllers;
use yii\web\Controller;
class PostController extends Controller
{
public function actionIndex()
{
return $this->render('index');
}
}This creates a controller with one action called actionIndex(). By default, each action corresponds to a method that starts with action.
Creating the Action
The next step after creating the controller is defining the actions it will handle. An action is simply a public method inside the controller that starts with the word action. For example, actionView() or actionCreate().
Inside the action, you can perform logic like fetching data from a model, processing forms, or rendering views. Here's a slightly expanded version of the previous example:
public function actionView($id)
{
$post = Post::findOne($id);
if (!$post) {
throw new \yii\web\NotFoundHttpException();
}
return $this->render('view', ['post' => $post]);
}In this case, the actionView() expects an $id parameter, which is automatically parsed from the request URL when using pretty URLs (more on that below).
Configuring the URL Format
By default, Yii uses a query-based URL format like /index.php?r=post/view&id=1. But for cleaner and more SEO-friendly URLs, you'll want to enable pretty URLs.
To do this, update the urlManager component in your configuration (config/web.php):
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' => [
'post/<id:\d >' => 'post/view',
'posts' => 'post/index',
],
],Also make sure your .htaccess file is set up properly if you're using Apache, so that all requests get redirected to index.php.
With these settings, visiting /posts will run the index action in the PostController, and /post/5 will show the post with ID 5.
You don’t always have to define every rule manually — Yii has a default pattern where it assumes URLs like /controller-id/action-id map directly to ControllerName::actionActionName(). So /post/view?id=5 also works without any custom rules.
- Make sure controller files are in the correct folder
- Use
actionprefix for methods you want to expose as routes - Enable pretty URLs for cleaner paths
- Define custom URL rules only when needed
That’s basically all you need to create a basic route in Yii. It's not complicated, but there are a few moving parts like controller placement, action naming, and URL formatting that are easy to overlook.
