Yii2 How can I display Activeform radioList data on screen? - yii

Question

I have not experience with Yii2.
I would like to be able to show the result of a form on the screen.
With the fields name and email I have no problem but I can not show the selection
that I make of my radioList.
I have tried many methods but none works.
Can you help me please?
These are my files.
SiteController.php
public function actionEntry()
{
$this->layout = 'print';
$model = new EntryForm();
if ($model->load(Yii::$app->request->post()) && $model->validate()) {
return $this->render('entry-confirm', ['model' => $model]);
} else {
return $this->render('entry', ['model' => $model]);
}
}
EntryForm.php
namespace app\models;
use Yii;
class EntryForm extends \yii\db\ActiveRecord
{
public $name;
public $email;
public $category;
public function rules()
{
return [
[['name', 'email'], 'required'],
['email', 'email'],
];
}
entry.php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'name') ?>
<?= $form->field($model, 'email') ?>
<?= $form->field($model, 'category')->radioList([
1 => 'radio 1',
2 => 'radio 2'
]);
?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
entry-confirm.php
<p>You have entered the following information:</p>
<ul>
<li><label>Name</label>: <?= Html::encode($model->name) ?></li>
<li><label>Email</label>: <?= Html::encode($model->email) ?></li>
<li><label>Category</label>: <?= Html::encode($model->category) ?></li>
</ul>

In model extending ActiveRecord you must never explicitly define properties that are the same as names of columns in DB.
You must define at least one validation rule for each attribute that is set by the end user, otherwise system will not allow to set it.
