function hook_theme_suggestions_HOOK in Drupal 9

Same name and namespace in other branches

1. 8 core/lib/Drupal/Core/Render/theme.api.php \hook_theme_suggestions_HOOK()

Provides alternate named suggestions for a specific theme hook.

This hook allows modules to provide alternative theme function or template name suggestions.

HOOK is the least-specific version of the hook being called. For example, if '#theme' => 'node__article' is called, then hook_theme_suggestions_node() will be invoked, not hook_theme_suggestions_node__article(). The specific hook called (in this case 'node__article') is available in $variables['theme_hook_original'].

Implementations of this hook must be placed in *.module or *.theme files, or must otherwise make sure that the hook implementation is available at any given time.

@todo Add @code sample.

Parameters

array $variables: An array of variables passed to the theme hook. Note that this hook is invoked before any preprocessing.

Return value

array An array of theme suggestions.
