I have created a widget to render the form in layouts/main.php footer section.
This is a widget file named common\widget\SubscriberFormWidget.php
<?php
namespace common\widgets;
use Yii;
use yii\base\Widget;
use common\models\Subscriber;
class SubscriberFormWidget extends Widget
{
/**
*@return string
*/
public function run()
{
$model = new Subscriber();
return $this->render('_form', [
'model' => $model
]);
}
}
This is _form file used in above widget located in common\widget\views\_form.php
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
/* @var $this yii\web\View */
/* @var $model common\models\Subscriber */
/* @var $form yii\widgets\ActiveForm */
?>
<?php $form = ActiveForm::begin(['action' => ['subscriber/subscribe']]); ?>
<div class="row">
<div class="col-md-6">
<?= $form->field($model, 'email')->textInput(['maxlength' => true, 'placeholder' => 'Enter @ Email to subscribe!'])->label(false) ?>
</div>
<div class="col-md-6">
<?= Html::submitButton('Subscribe', ['class' => 'btn btn-success']) ?>
</div>
</div>
<?php ActiveForm::end(); ?>
This is controller file frontend\controllers\SubscriberController.php
<?php
namespace frontend\controllers;
use Yii;
use common\models\Subscriber;
use common\models\SubscriberSearch;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
/**
* SubscriberController implements the CRUD actions for Subscriber model.
*/
class SubscriberController extends Controller
{
/**
* Creates a new Subscriber model.
* If creation is successful, the browser will be redirected to the 'view' page.
* @return mixed
*/
public function actionSubscribe()
{
$model = new Subscriber();
if ($model->load(Yii::$app->request->post()) && $model->validate()) {
if ($model->sendEmail()) {
Yii::$app->session->setFlash('success', 'You have successfully subscribed My-Blog. You will get notification whenever New post is published');
return $this->redirect(Yii::$app->request->referrer);
} else {
Yii::$app->session->setFlash('error', 'Sorry, we are unable to subscribe for the provided email address.');
}
}
return $this->redirect([Yii::$app->request->referrer, ['model' => $model]]);
}
/**
* Creates a new Subscriber model.
* If unsubscribe is successful, the browser will be redirected to the 'view' page.
* @return mixed
*/
}
I have used widget in layouts\main.php in footer section
<footer class="footer">
<div class="container">
<div class="row">
<div class="col-md-3">
<p class="pull-left">© <?= Html::encode(Yii::$app->name) ?> <?= date('Y') ?></p>
</div>
<div class="col-md-6 text-justify" style="border-left : 2px solid black; border-right: 2px solid black">
<?= SubscriberFormWidget::widget(); ?>

This is model used for controller common\models\Subscriber.php
<?php
namespace common\models;
use Yii;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\db\Expression;
/**
* This is the model class for table "subscriber".

class Subscriber extends \yii\db\ActiveRecord
{
const STATUS_DEACTIVE = 0;
const STATUS_ACTIVE = 1;
/**
* @inheritdoc
*/
public static function tableName()
{
return 'subscriber';
}
public function behaviors()
{
return [
'timestamp' => [
'class' => TimestampBehavior::className(),

public function rules()
{
return [
[['email'], 'required'],
[['status', 'created_at', 'updated_at'], 'safe'],
[['email'], 'string', 'max' => 60],

];
}
/**

*/
public function generateSubscriberToken()
{
return $this->token = Yii::$app->security->generateRandomString() . '_' . time();
}
/**
* Send Email when successfully subscribe
*/
public function sendEmail()
{
$subscribers = self::find()->where(['email' => $this->email])->one();
//set flag for sending email
$sendMail = false;
//email subject
$subject = '';
//generate token
$token = $this->generateSubscriberToken();
//if email found in subscribers
if ($subscribers !== null) {
//check if inactive
if ($subscribers->status !== self::STATUS_ACTIVE) {
//assign token
$subscribers->token = $token;
//set status to active
$subscribers->status = self::STATUS_ACTIVE;
print_r($subscribers->errors);
//update the recrod
if (!$subscribers->save()) {
return false;
}
//set subject
$subject = 'Welcome back ' . $this->email . 'Thank you for subscribing ' . Yii::$app->name . '<br /><br /> You will receive notification whenever new trick or post is published to website';
$sendMail = true;
}
} else { //if email does not exist only then insert a new record
$this->status = 1;
if (!$this->save()) {
return false;
}
$subject = 'Thank you ' . $this->email . ' for subscribing ' . Yii::$app->name . '<br /><br /> You will receive notification whenever new trick or post is published to website';
$sendMail = true;
}
//check if send mail flag set
if ($sendMail) {
return Yii::$app->mailer
->compose()
->setFrom(['noreply@my-blog.com' => Yii::$app->name . ' robot'])
->setTo('piyush@localhost')
->setSubject('Subscription : ' . Yii::$app->name)
->setHtmlBody($subject)
->send();
}
}
}
Now I want form to be worked with validation. If user enter any wrong input like already registered then, message for this should return to view file from which submitted form data.
