Yii2 doesn't work yii2-poll-widget - yii2

Question

I use yii2-poll-widget on my page.
I installed it:
php composer.phar require "pollext/poll":"dev-master"
And write on my page:
<?php
use pollext\poll\Poll;?>
<?php
echo Poll::widget([
'pollName'=>'Do you like PHP?',
'answerOptions'=>
[
'Yes',
'No',
],
]);
?>
But I get error:
Unknown Property – yii\base\UnknownPropertyException
Setting unknown property: pollext\poll\Poll::pollStatus
How can I solve my problem?

Answer 1

I do not recommend pollext/poll because it contains multiple errors in its core code, like missing ) or undefined index. We (I and 2 more people) tried to fix errors in its core files by hand (I know we shouldn't do that as it's a widget, sitting in vendor directory but at least we could see if it works at all).
You can try to use this code below (what we added/modified is not much, we did more to improve design and functionality but still wasn't good enough, not worth to continue):
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use pollext\poll\AjaxSubmitButton;
use yii\helpers\Url;
?>
<style>
.poll{
display: inline-block;

margin-bottom: 10px;

}
.poll label{
width: 100%;
font-size: 10pt;
font-weight: bold;
display: block;
color: #464646;
}
.poll label:hover{
cursor: pointer;
}
.poll button[type="submit"]{
font-weight: bold;
font-size: 10pt;
margin-top: 10px;

}
.poll-option-name{

This modified come is taken from pollext/views/index.php file. In case you're wondering how it looks like:
Upper is a view for a person who didn't vote yet and below is a view for a person who have already voted.
