public AttachmentsResponseProcessorInterface::processAttachments(AttachmentsInterface $response)
Processes the attachments of a response that has attachments.
Libraries, JavaScript settings, feeds, HTML <head> tags, HTML <head> links, HTTP headers, and the HTTP status code are attached to render arrays using the #attached property. The #attached property is an associative array, where the keys are the attachment types and the values are the attached data. For example:
1 2 3 4 5 6 | $build['#attached']['library'][] = [ 'library' => ['core/jquery']];$build['#attached']['http_header'] = [ ['Content-Type', 'application/rss+xml; charset=utf-8'],]; |
The available keys are:
- 'library' (asset libraries)
- 'drupalSettings' (JavaScript settings)
- 'feed' (RSS feeds)
- 'html_head' (tags in HTML <head>)
- 'html_head_link' (<link> tags in HTML <head>)
- 'http_header' (HTTP headers and status code)
Parameters
\Drupal\Core\Render\AttachmentsInterface $response: The response to process.
Return value
\Drupal\Core\Render\AttachmentsInterface The processed response, with the attachments updated to reflect their final values.
Throws
