WP Subtitle

The WP Subtitle plugin allows your pages and posts to contain a subtitle. Also called a sub-heading, this this short line of text is meant to appear beneath a post’s (or page’s) title, but can be inserted in your template wherever you choose.

The subtitle can be inserted into your theme template files (or plugin) using the following API:

Display The Subtitle

All parameters are optional. If ‘post_id’ is omitted then the current post ID in the loop is used.

PHP Code:

do_action( 'plugins/wp_subtitle/the_subtitle', array(
    'before'        => '<p class="subtitle">',
    'after'         => '</p>',
    'post_id'       => get_the_ID(),
    'default_value' => ''
) );

Output:

<p class="subtitle">My Post Subtitle</p>

Get The Subtitle

All parameters are optional. If ‘post_id’ is omitted then the current post ID in the loop is used.

A default value can be supplied as the second parameter for apply_filters. This will be used if the post does not have a subtitle. Leave as an empty string to return an empty string if the post does not have a subtitle.

PHP Code:

$subtitle = apply_filters( 'plugins/wp_subtitle/get_subtitle', '', array(
    'before'  => '<p class="subtitle">',
    'after'   => '</p>',
    'post_id' => get_the_ID()
) );

Result:

$subtitle = '<p class="subtitle">My Post Subtitle</p>'

Subtitles can automatically be added to your WooCommerce products without needing to make template changes. In the admin go to WooCommerce > Settings > Products where you can choose to:

Yoast SEO and SEOPress Plugin Support
