KIA Subtitle


KIA subtitle allows you to easily add a subtitle to your posts and retrieve it in the loop in the same manner as the post title. By using the_subtitle() or get_the_subtitle().

It adds a simple input field right under the title field of posts, pages and any custom post type. It also add a subtitle column to the edit screen as well as to the quick edit.

You can also use the shortcode [the-subtitle] to display it within the post content.

WPML Ready

KIA Subtitle has been tested by WPML and will allow you to translate the subtitle multilingual sites.


Support is handled in the WordPress forums. Please note that support is limited and does not cover any custom implementation of the plugin.

Please report any bugs, errors, warnings, code problems to Github


  • This is what the input will look like in the Block Editor.
  • This is what the input will look like in the Classic Editor.


  1. Upload the plugin folder to the /wp-content/plugins/ directory
  2. Activa el plugin en menú ‘Plugins’ de WordPress
  3. Add the ‘the_subtitle()’ tag to your theme:
    if(function_exists(‘the_subtitle’)) the_subtitle();
  4. if you need to ‘return’ the value, you can use get_the_subtitle() which accepts a $post_id parameter if you need to use it outside the loop
    if(function_exists(‘the_subtitle’)) $subtitle = get_the_subtitle( $post_id );
  5. As of version 1.2 the_subtitle accepts 3 parameters: the_subtitle( $before = Null, $after = Null, $echo = True );
  6. As of version 1.3.4, there is a filter for the_subtitle


How do I display the subtitle in my theme?

The simplest way is with the the_subtitle() template tag as follows:

if( function_exists( 'the_subtitle' ) ) the_subtitle();

You can wrap the string in some markup using the $before and $after parameters.

if( function_exists( 'the_subtitle' ) ) the_subtitle( '<h2 class="subtitle">', '</h2>' );

Where do I add this code?

Unfortunately, I cannot tell you exactly what file to place the above code in because 1. I don’t know where you want to display the subtitle and 2. every theme’s structure is different.

However, in general, the_subtitle() is a template tag so you will want to put it in a template file. Probably, you are looking for the file that contains your post loop. For most themes it’s single.php ( or page.php for pages ), but for many it could also be content.php. Assuming you want the subtitle to display directly after your main title, you’d place the above code after:

<h1 class="entry-title"><?php the_title(); ?></h1>

As an example if you wanted to display the subtitle on standard single posts, in the Twenty Twenty theme you’d create a copy of the entry-header.php template in your child theme and modify it as shown in this gist

How do I style the subtitle?

If you have wrapped the subtitle in an H2 tag with the class of subtitle like in the gist above, you can then style it any way you’d like.

.subtitle { color: pink; }

Can I display the subtitle for my WooCommmerce products

Yes! You can use this bridge plugin to automatically display the subtitle in most WooCommerce locations.

Can I add the subtitle to the Page Title Meta tag

function kia_add_subtitle_to_wp_title( $title ) {
if ( is_single() && function_exists(‘get_the_subtitle’)) && $subtitle == get_the_subtitle( get_the_ID() ) ) {
$title .= $subtitle;

Is this translation ready?

WPML now supports KIA Subtitle!

It is a simple and very useful plugin that I have already used on more than one occasion. It works perfectly with several different themes. Currently used with Woocommerce on Avada theme and WordPress 5.6.2 Thank you very much

Well done. I spent hours trying to add a subtitle field with other plugins with no luck. Finally with KIA it works!

Still the only possible solution to add "brand" subtitles to my Woocommerce products in my theme - works like a charm on single and catalogue pages. However, I hope that maybe one day the subtitles will allow to link to other sites 🙂 Then it will be perfect.
