function hook_views_post_render

Post-process any render data.

The module or theme may add, modify or remove elements in $output after rendering.

If a module wishes to act on the rendered HTML of the view rather than the structured content array, it may use this hook to add a #post_render callback:

// The object must implement \Drupal\Core\Security\TrustedCallbackInterface.
$output['#post_render'][] = '\\Drupal\\my_module\\View::postRender';

See \Drupal\Core\Render\RendererInterface::render() for #post_render documentation.

Alternatively, it could also implement hook_preprocess_HOOK() for the particular view template, if there is one.

Parameters

\Drupal\views\ViewExecutable $view: The view object being processed.

array $output: A structured content array representing the view output. The given array depends on the style plugin and can be either a render array or an array of render arrays.

\Drupal\views\Plugin\views\cache\CachePluginBase $cache: The cache settings.
