Same name and namespace in other branches
- 8.0 core/lib/Drupal/Core/Render/theme.api.php \hook_theme_suggestions_HOOK_alter()
Alters named suggestions for a specific theme hook.
This hook allows any module or theme to provide alternative theme function or template name suggestions and reorder or remove suggestions provided by hook_theme_suggestions_HOOK() or by earlier invocations of this hook.
HOOK is the least-specific version of the hook being called. For example, if '#theme' => 'node__article' is called, then node_theme_suggestions_node() will be invoked, not node_theme_suggestions_node__article(). The specific hook called (in this case 'node__article') is available in $variables['theme_hook_original'].
@todo Add @code sample.
Parameters
array $suggestions: An array of theme suggestions.
array $variables: An array of variables passed to the theme hook. Note that this hook is invoked before any preprocessing.
