class UserController extends Controller
{
public function behaviors()
{
    return [
        'access' => [
            'class' => AccessControl::className(),
            'only' => ['logout'],
            'rules' => [
                [

    $model = new UserForm();                                                     
    if ($model->user(Yii::$app->request->post())) {

        return $this->render('user', [

Below is my model file

<?php
namespace app\models;

use Yii;
use yii\base\Model;

use yii\db\ActiveRecord;
/**
 * ContactForm is the model behind the contact form.
 */
class UserForm extends yii\db\ActiveRecord
{
public $name;
public $email;
const STATUS_INACTIVE = 0;
const STATUS_ACTIVE = 1;

public static function tableName()
{
    return 'user';
}

public function rules()
{
    return [
        // name, email, subject and body are required
        [['name', 'email', 'subject', 'body'], 'required'],
        // email has to be a valid email address
        ['email', 'email'],
        // verifyCode needs to be entered correctly
        //['verifyCode', 'captcha'],
    ];
}
/**
 * Sends an email to the specified email address using the information collected by this model.
 * @param  string  $email the target email address
 * @return boolean whether the model passes validation
 */
public function user($email)
{
    //$model->name = $ContactForm['name'];
/*  if(!empty($UserForm)){ 
        $model->name = $UserForm['UserForm']['name'];
        $model->email = $UserForm['UserForm']['email'];



           Yii::$app->mailer->compose()
                ->setTo($email)
                ->setFrom([$this->email => $this->name])
                ->setSubject($this->subject)
                ->setTextBody($this->body)
                ->send(); */
                if ($this->validate()) {
                $form = new Form();
                $form->name = $this->name;
                $form->email = $this->email;
                $form->save();


            return true;
        } else {
            return false;
        }
    }
    }

    ?>

below is my view file

    <?php
    use yii\helpers\Html;
    use yii\bootstrap\ActiveForm;
    use yii\captcha\Captcha;

    /* @var $this yii\web\View */
    /* @var $form yii\bootstrap\ActiveForm */
    /* @var $model app\models\ContactForm */

    $this->title = 'User';
    $this->params['breadcrumbs'][] = $this->title;
    ?>
    <div class="site-contact">
    <h1><?= Html::encode($this->title) ?></h1>

    <?php if (Yii::$app->session->hasFlash('contactFormSubmitted')): ?>

    <div class="alert alert-success">
    Thank you for contacting us. We will respond to you as soon as possible.
    </div>

    <p>
    Note that if you turn on the Yii debugger, you should be able
    to view the mail message on the mail panel of the debugger.
    <?php if (Yii::$app->mailer->useFileTransport): ?>
    Because the application is in development mode, the email is not sent but saved as
    a file under <code><?= Yii::getAlias(Yii::$app->mailer->fileTransportPath) ?></code>.
    Please configure the <code>useFileTransport</code> property of the <code>mail</code>
    application component to be false to enable email sending.
    <?php endif; ?>
    </p>

    <?php else: ?>
