How to pass parameters to widget?

Question

Yii

I have the following widget:

class Polls extends \yii\base\Widget {


  public function run() {
    $poll = Poll::findOne(20);
    $answers = Poll_choice::find()->where('poll_id = 20')->all();
    if($poll){
      if(!$poll->userCanVote(\Yii::$app->request->userIP)){
        $pollVote = new Poll_vote();
        if(Poll_choice::issetChoiceInPoll($poll->id, 56)){
          $pollVote->poll_id = $poll->id;
          $pollVote->choice_id = 56;
          $pollVote->user_id = \Yii::$app->user->id;
          $pollVote->ip_address = \Yii::$app->request->userIP;
        $pollVote->save();
        }else
          echo "Test";
      }
    }
  return $this->render('poll.twig',[
    'question' => $poll,
    'answers' => $answers,
  ]);
  }
}

At the moment, static parameters are passed in the model.
The work is done with the twig template engine. I just can’t figure out how to transfer data from the page to this widget, for example, using the post method.

Answer 1

Add property to widget like message

class Polls extends \yii\base\Widget {
    public $message;
    ...
}

Then, to pass the $message parameter to the widget, it is enough to use the code:

<?php
use app\components\Polls;
?>
<?= Polls::widget(['message' => ' Yii2.0']) ?>
