Secondary Title provides several filters that allow developers to hook into some of the plugin's functions and modify its workflow and output. To learn more about using filters in WordPress, please read the related article in the Codex.
get_secondary_title($secondary_title, $post_id, $prefix, $suffix)
the_secondary_title($secondary_title, $post_id, $prefix, $suffix)
These two filters change the output of the final secondary title for a post.
$secondary_title(string): The unmodified secondary title of a post.
$post_id(int): Targeted post.
$prefix(string): Characters inserted before the secondary title.
$suffix(string): Characters inserted after the secondary title.
Hooks into the end of the
secondary_title_get_default_settings function and modifies its output.
