Not able to submit form inside footer in Yii2 - yii

Question

I've a subscribe newsletter form inside footer that display on all page. To do this I've created a subscriber widget like this:
SubscriberWidget.php
<?php
namespace frontend\components;
use Yii;
use yii\base\Widget;
use yii\helpers\Html;
use frontend\models\SubscribeNewsletterForm;
class SubscriberWidget extends Widget
{
public function run()
{
$subscriber_model = new SubscribeNewsletterForm();
return $this->render('_subscribe-newsletter-form.php', [
'subscriber_model' => $subscriber_model
]);
}
}
?>
Here's the SubscribeNewsletterForm model code:
SubscribeNewsletterForm.php
<?php
namespace frontend\models;
use Yii;
use yii\base\Model;
class SubscribeNewsletterForm extends Model
{
public $email;
public function rules()
{
return [
[['email'], 'required'],
['email', 'email']
];
}
}
?>
Here is the code of my _subscribe-newsletter-form.php
<?php
use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
use yii\helpers\Url;
?>
<h3>Subscribe to Newsletter</h3>
<?php $form = ActiveForm::begin(['id' => $subscriber_model->formName(), 'action' => ['project/subscriber'], 'validateOnBlur' => false, 'validateOnType' => false]); ?>
<div class="input-group">
<?= $form->field($subscriber_model, 'email')->textInput()->label(false); ?>
<span class="input-group-btn">
<?php echo Html::submitButton('Sign Up', ['class' => 'btn btn-primary subscribe-btn']); ?>
</span>
</div>
<?php ActiveForm::end(); ?>
<?php
$script = <<< JS
$('#{$subscriber_model->formName()}').on('beforeSubmit', function(e){
var form = $(this);
$.post(
form.attr("action"),
form.serialize()
).done(function(data){
form.trigger("reset");
})
return false;
});
JS;
$this->registerJs($script);
?>
Inside ProjectController.php I've created the action as follow:
public function actionSubscriber()
{
$subscriber_model = new SubscribeNewsletterForm();
$request = Yii::$app->request;
if($request->isAjax && $subscriber_model->load($request->post())){
$subscriber = new Subscriber([
'email' => $subscriber_model->email
]);
$subscriber->save();
}
}
Here's the Subscriber model code.
Subscriber.php
<?php
namespace frontend\models;
use yii\db\ActiveRecord;
class Subscriber extends ActiveRecord
{
public static function tableName()
{
return 'subscriber';
}
}
?>
frontend/config/main.php
<?php
$params = array_merge(
require(__DIR__ . '/../../common/config/params.php'),
require(__DIR__ . '/../../common/config/params-local.php'),
require(__DIR__ . '/params.php'),
require(__DIR__ . '/params-local.php')
);
return [
'id' => 'app-frontend',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'controllerNamespace' => 'frontend\controllers',
'components' => [
'request' => [
'csrfParam' => '_csrf-frontend',
],
'user' => [
'identityClass' => 'common\models\User',
'enableAutoLogin' => true,
'identityCookie' => ['name' => '_identity-frontend', 'httpOnly' => true],
],
'session' => [
// this is the name of the session cookie used for login on the frontend
'name' => 'advanced-frontend',
],
'log' => [
'traceLevel' => YII_DEBUG ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'errorHandler' => [
'errorAction' => 'site/error',
],
/*
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' => [
],
],
*/
],
'params' => $params,
];
?>
With above code validation is working but i'm not able to save the email in database. Please tell what i'm doming wrong.

You need rules on your Model. Also, I always replace the generated tables names with the table prefix supported method. Also, I always like to use the Timestamp behavior to log when things are created or updated. Especially when your grabbing contact info for the use of leads, I would record the timestamps as well as their IP Address.
Subscriber.php
use yii\behaviors\TimestampBehavior;
// ...
/**
* #inheritdoc
*/
public static function tableName()
{
return '{{%subscriber}}';
}
/**
* #inheritdoc
*/
public function behaviors()
{
return [
TimestampBehavior::className(),
];
}
/**
* #inheritdoc
*/
public function rules()
{
return [
['email', 'filter', 'filter' => 'trim'],
['email', 'required'],
['email', 'email'],
['email', 'string', 'max' => 255],
['email', 'unique', 'targetClass' => '\common\models\Subscriber', 'message' => 'This email address has already been taken.'],
[['created_at', 'updated_at'], 'integer'],
];
}
