hook_tokens_alter(array &$replacements, array $context, \Drupal\Core\Render\BubbleableMetadata $bubbleable_metadata)
Alter replacement values for placeholder tokens.
Parameters
$replacements: An associative array of replacements returned by hook_tokens().
$context: The context in which hook_tokens() was called. An associative array with the following keys, which have the same meaning as the corresponding parameters of hook_tokens():
- 'type'
- 'tokens'
- 'data'
- 'options'
\Drupal\Core\Render\BubbleableMetadata $bubbleable_metadata: The bubbleable metadata. In case you alter an existing token based upon a data source that isn't in $context['data'], you must add that dependency to $bubbleable_metadata.
