HowTo: Use custom Snippet-Description based on theme

[Tobias Battenberg]

Hi,

how can I set a custom "description" for example on a page that has the theme/blueprint "event-article"?
I want to show the event_date and event_location in the snippet and I want to do this automatically, cause the editors on the website wont enter these informations into the snippet-fields by hand …

Cheers,
Tobias

Using a page model, you can set meta data programatically like this:

<?php

class EventArticlePage extends Page
{
  /**
   * Programmatic SEO defaults
   */
  public function metaDefaults()
  {
    return [
      'metaDescription' => $this->text()->excerpt(160),
      'fieldName' => 'blabla',
    ];
  }
 }
