1 comment.api.php hook_comment_view_alter(&$build)

Alter the results of comment_view().

This hook is called after the content has been assembled in a structured array and may be used for doing processing which requires that the complete comment content structure has been built.

If the module wishes to act on the rendered HTML of the comment rather than the structured content array, it may use this hook to add a #post_render callback. Alternatively, it could also implement hook_preprocess_comment(). See backdrop_render() and theme() documentation respectively for details.


$build: A renderable array representing the comment.
