yii2 csrf custom form

Sure! Here's an example of how you can implement a custom CSRF token form in Yii2:

In your view file, you can include the CSRF token by using the yii\helpers\Html class and the yii\web\View object. Here's an example:

use yii\helpers\Html;
use yii\web\View;

$csrfToken = Yii::$app->request->getCsrfToken();
$this->registerJsVar('csrfToken', $csrfToken, View::POS_HEAD);

Then, you can use the $csrfToken variable in your form by including it as a hidden input field. Here's an example:

<?= Html::hiddenInput(Yii::$app->request->csrfParam, $csrfToken) ?>

Make sure to include this hidden input field in your form so that the CSRF token is included in the form submission.

Once the CSRF token is included in your form, you can validate it in your controller action using the yii\web\Controller class. Here's an example:

use yii\web\Controller;

class YourController extends Controller
    public function actionYourAction()
        $request = Yii::$app->request;

        if ($request->validateCsrfToken()) {
            // CSRF token is valid, continue with your action logic
        } else {
            // CSRF token is invalid, handle the error

By calling $request->validateCsrfToken(), Yii2 will automatically compare the CSRF token included in the form submission with the one stored in the session. If they match, the token is considered valid and you can proceed with your action logic. Otherwise, you can handle the error accordingly.

That's it! You have implemented a custom CSRF token form in Yii2 without using any personal words or sentences.
