Alternatively, when using ''iframe'':

=== Custom Metatags in Views === You need the following metatags for the pages being generated:



  
  Your Website Title
    
	
	
	
	
	
  
  
  ...

In Yii, these meta tags have to be inserted in the required view:


$curUri = Html::encode(Yii::$app->params['companyWebsite'].Yii::$app->request->getUrl());
$this->registerMetaTag(['property' => 'og:url',         'content' => $curUri]);
$this->registerMetaTag(['property' => 'og:type',        'content' => 'article']);
$this->registerMetaTag(['property' => 'og:title',       'content' => Html::encode($this->title)]);
$this->registerMetaTag(['property' => 'og:description', 'content' => strip_tags($model['intro_text'])]);
$this->registerMetaTag(['property' => 'og:image',       
  'content' => Html::encode(Yii::$app->params['companyWebsite'] . 
                 Yii::$app->urlManagerBackend->createUrl('').'media/'.$model['main_image']
               )]);
echo "\n\n";
    
// Load Facebook SDK for JavaScript
echo '
      
        ';
echo "\n\n";

// Facebook 'Like' button code
echo '
      
      ';
echo "\n\n";

=== Custom Metatags in Controllers === Alternatively, you can automatically add it to each view. First, add it to your controller, or create your own extended version of ''Controller'', such as ''MyController'':


class MyController extends Controller
{    
    public function beforeAction($event)
    {
      $this->view->title = Yii::$app->params['pageTitle'];

      // Get customized meta tags (keywords, author, etc.) from the params config file as a default.
      \Yii::$app->view->registerMetaTag(Yii::$app->params['pageDefaultDescription'], "default_description");
      \Yii::$app->view->registerMetaTag(Yii::$app->params['pageDefaultKeywords'],    "default_keywords");
      \Yii::$app->view->registerMetaTag(Yii::$app->params['pageDefaultAuthor'],      "default_author");

      // Open Graph Tags
      \Yii::$app->view->registerMetaTag(Yii::$app->params['pageDefaultOG_Description'], "default_og_description");
      \Yii::$app->view->registerMetaTag(Yii::$app->params['pageDefaultOG_SiteName'],    "default_og_sitename");
      \Yii::$app->view->registerMetaTag(Yii::$app->params['pageDefaultOG_Title'],       "default_og_title");
      \Yii::$app->view->registerMetaTag(Yii::$app->params['pageDefaultOG_Type'],        "default_og_type");

      return parent::beforeAction($event);
    }
}

Any new controllers created would extend ''MyController'' (instead of ''Controller''), to get the defaults meta tags attached automatically. If you need to customize a meta tag in some actions, you can override it:


class FancyController extends MyController
{
  ...
  public function actionIndex()
  {
      // Replace the default value for 'description'
      \Yii::$app->view->registerMetaTag([
          'name'    => 'description',
          'content' => 'A custom description for Index view',
          'id'      => 'main_index'
        ],
        'main_index'
      ); 

      return $this->render('index');
  }
}
