How to pass title and description to title?

Question

Yii

Good morning. I have my own title, description, keywords in the database for different types of pages. How can I pass them to the title so that the page does not display a sticky title, but the one that is registered in the database for a specific category of the page,
I try to display all this like this

$this->title = $model->meta_title;
$this->registerMetaTag(['name' => 'description', 'content' => $model->meta_description]);
$this->registerMetaTag(['name' => 'keywords', 'content' => $model->meta_keywords]);

Answer 1

You are doing everything right. If this code is in the view and if there is an output in the layout (give the layout code).

Answer 2

From controller - $this->view->title.
From the view -$this->title

Answer 3

This is how you form the resulting data array collected from the model in the controller and send it to the view.
So shove the meta data into your array keys, and print out in the view
<title><?=($title ? $title : '');?></title>
