Filter hooks

This is a full reference of the filters Highend's own theme code exposes: everything you can hook into with add_filter() from a child theme's functions.php to change a computed value (an array of classes, a query's arguments, an option's value, and so on) without editing the parent theme. It doesn't cover WordPress core filters the theme happens to call (the_content, widget_title, and similar) or WPBakery's own VC_SHORTCODE_CUSTOM_CSS_FILTER_TAG-based filters inside vc_templates/; those are documented by WordPress core and WPBakery themselves.

For the counterpart list of do_action() calls, see Action hooks.

These are the filters you're most likely to reach for. Full reference tables for everything else follow below.

Add a social networkCopy Anchor Link

add_filter( 'highend_social_networks_array', 'highend_child_add_social_network' );

function highend_child_add_social_network( $networks ) {

	$networks['mastodon'] = 'Mastodon';

	return $networks;
}

Override one option valueCopy Anchor Link

add_filter( 'highend_options_value', 'highend_child_force_boxed_layout', 10, 2 );

function highend_child_force_boxed_layout( $value, $option_name ) {

	if ( 'hb_global_layout' === $option_name ) {
		return 'hb-boxed-layout';
	}

	return $value;
}

Narrow the related-posts query to the same categoryCopy Anchor Link

add_filter( 'highend_post_related_articles_args', 'highend_child_related_args', 10, 2 );

function highend_child_related_args( $args, $post_id ) {

	$categories = wp_get_post_categories( $post_id );

	if ( $categories ) {
		$args['category__in'] = $categories;
	}

	return $args;
}

Layout and wrapper classesCopy Anchor Link

Header, navigation, and page titleCopy Anchor Link

Top bar widgetsCopy Anchor Link

Each top bar widget (info, map, email, login, languages, cart, custom_link, socials) exposes a _class filter and an _output filter with the same signature; the info, map, email, and custom_link widgets also expose _icon and _text filters. All live in functions/template-parts.php.

Every _output filter receives just the final HTML string for that widget, so it's the simplest way to change one widget's markup without a template override.

Footer, sidebars, and commentsCopy Anchor Link

Content, blog, and single postCopy Anchor Link

Page and archive titlesCopy Anchor Link

Each of these filters the resolved title or description string for one specific context, all in functions/common.php:

highend_home_page_title, highend_blog_page_title, highend_404_page_title, highend_search_page_title, highend_woocommerce_product_category_title, highend_bbp_forum_archive_title, highend_author_page_title, highend_single_faq_page_title, highend_single_testimonials_page_title, highend_search_page_description, highend_archive_day_description, highend_archive_month_description, highend_archive_year_description.
