I have the following code ` class PopularContentParselyBlock extends BlockBase {

 /**
  * {@inheritdoc}
  */

 public function build() {
 $client = new \GuzzleHttp\Client();
 $res = $client->request('GET', 'http://www.APIURL.com');
 $decoded = json_decode($res->getBody(),TRUE);
 foreach($decoded['data'] as $article) {
    $url = Url::fromUri( $article['url']);
    $endpoint = Link::fromTextAndUrl($article['title'], $url);

    }
  return $endpoint->toRenderable();
  }
}

`

When it prints out though all I get us Object. What am I doing wrong?

  • How are you printing it? Ideally it should be in a template but because Twig understands render arrays I'm assuming not? – Clive Feb 1 '16 at 19:44
  • This is the end of the class. Sorry I forgot to add it to start. } return [ '#markup' => $endpoint, ]; } – StevenPatz Feb 1 '16 at 19:58

#markup is used for content that has already been rendered. As the caller seems to be expecting a render array, you can just return it directly:

return $endpoint->toRenderable();

  • That yields this error: Call to a member function toRenderable() on string – StevenPatz Feb 1 '16 at 20:23
  • Hmm. I have this in a foreach loop and if I don't concatenate items onto $endpoint it works. – StevenPatz Feb 1 '16 at 20:29
  • That error doesn't really make sense in this narrow context, maybe you can edit the question and add the full code for this function? And what it is e.g. Controller? – Clive Feb 1 '16 at 20:32
  • It's a block so in a Plugin. Code is updated. That works. But there are 5 urls that need created – StevenPatz Feb 1 '16 at 20:42
  • This was the closest to what I needed to do to get this to work. Turns out that making $endpoint an array and then looping through that array in the twig template produced what we needed. – StevenPatz Feb 2 '16 at 15:19

You have to put the links in some kind of a render array, for example:

$build['links'] = array(
  '#theme' => 'links',
  '#links' => $links,
);
return $build;

  • After a meeting this afternoon I realized I probably need to just have this array of links sent off to a twig template where a foreach in there would output what I need. Going to try your suggestion though. – StevenPatz Feb 1 '16 at 23:31
  • Look at the documentation, you need a sub array of href and title, no need for the link function, the template is doing this: api.drupal.org/api/drupal/… – 4k4 Feb 2 '16 at 7:15
