Filters and Actions (Hooks)

The filter hooks and action hooks of the premium version are only available if the plan enables the corresponding feature. You find the hooks of the free version on this page.

Hook into an action with add_action(). Example:

function group_is_gone_message( $group_id ) {
 echo "Group {$group_id} is gone!";
}
add_action( 'term_group_deleted', 'group_is_gone_message' );

Hook into a filter with add_filter(). Examples:

function wrap_as_gift( $html ) {
 return "<div class='wrapping_paper'>" . $html . "</div>";
}
add_filter( 'tag_groups_post_terms', 'wrap_as_gift' );

function add_my_icon_to_accordion_tag( $html, $id, $font_size, $post_count, $shortcode ) {
 if ('tag_groups_accordion' != $shortcode) {
  return $html;
 }
 return $html . '<img src="https://example.com/my-icon.png" style="height:' . $font_size . 'px"/>';
}
add_filter( 'tag_groups_cloud_tag_append', 'add_my_icon_to_accordion_tag', 10, 5 );
