Useful short helper functions to work with default Yii 2 components.


You have to run the following command to add a dependency to your project

composer require manchenkov/yii2-helpers

or you can add this line to require section of composer.json

After installation, you may use it in existing code like this:

use yii\web\Controller;

class SiteController extends Controller 
    public function actionIndex(): string
        if (app()->user->isGuest) {
            return view('guests');
        return view('main');
    // ...
    public function actionAjaxGetData(): string
        if (request()->isAjax) {
            $number = request()->get('number');
            // ...
        return view('main');
