Extend panel search to include `computed` model fields

I have a Page Model with a custom computed field bar which returns some computed data based on the content of this page.

class FooPage extends Page {
  public function bar() {
    return "foobar";
  }
}

Can I include this result from bar() into my panel search?

The use case for example could be a select field with custom label mappings coming from a config file. I now want to search pages for the selected labels.

I’m just guessing, but you might want to include your bar value into the page content.
Something like:

class FooPage extends Page {
  public function bar() {
    return "foobar";
  }

  public function content(string $languageCode = null) {
    $content = parent::content($languageCode);
    return $content->update(['bar' => $this->bar()]);
  }
}

thanks, it (almost) works.

i found that accessing actual content fields within the content() method is not possible via __call syntax since it creates an infinite loop.
so i had to access the \Kirby\Cms\Content object directly


class FooPage extends Page {
  public function bar() {
    return "foobar";
  }

  public function content(string $languageCode = null) {
    $content = parent::content($languageCode);
    $childContentBefore = $this->content;
    // work with $content->get("propertyName") instead of accessing properties with $this->propertyName() to avoid infinite loop
    return $content->update(['bar' => $this->bar()]);
  }
}
