/** * Snippet Name: Clean up and customize body_class * Snippet URL: https://wpcustoms.net/snippets/clean-up-and-customize-body_class/ */ function wpc_body_class($wp_classes, $extra_classes) { // List of classes allowed $whitelist = array('my_custom_class', 'another-class'); $wp_classes = array_intersect($wp_classes, $whitelist); return array_merge($wp_classes, (array) $extra_classes); } add_filter('body_class', 'wpc_body_class', 10, 2);
