Title: Modifying wp_head Last modified: August 19, 2016 --- # Modifying wp_head * [mituls](https://wordpress.org/support/users/mituls/) * (@mituls) * [17 years, 1 month ago](https://wordpress.org/support/topic/modifying-wp_head/) * Hi there, * I am trying to modify (not add) HTML content within the tags. * Therefore, I have created a wp_head filter within the functions.php file. However, I can’t seem to get it to work correctly. Can anyone help? * Step 1: ——- Here is my function in the functions.php file: * function mitulsdotcom_htmlCommentsStripper($content) { $find=”/\/”; $replace=””; return $value=preg_replace( $find,$replace,trim($content)); * } * ^ The above function takes in the content and strips of any HTML comments * Step 2: ——- * Here is my filter in the functions.php file: * add_filter(‘wp_head’, ‘mitulsdotcom_htmlCommentsStripper’); * Any help is greatly appreciated. * Kind regards, * Mitul Viewing 1 replies (of 1 total) * [nmac](https://wordpress.org/support/users/nmac/) * (@nmac) * [16 years, 8 months ago](https://wordpress.org/support/topic/modifying-wp_head/#post-1053461) * Hi Mitul, I am fairly sure that wp_head is an action hook and not a filter hook, so you cannot currently call add_filter on wp_head, just add_action. * I may be wrong, but FWIW, check out the API Filters list in the codex. * Nmac.
