Why doesn't it display description and keywords yii?

Question

Yii

I output via
$this->registerMetaTag(['name' => 'description', 'content' => $model->meta_description]);
$this->registerMetaTag(['name' => 'keywords', 'content' => $model->meta_keywords]);
neither appears in the view, if it's just echo $model->meta_description somewhere, then the content appears on the page

Answer 1

Most likely you didn't include $this->head() in your template.
