Description
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.
Displaying the subtitle on the front-end
This plugin does not attempt to output the subtitle. With an infinite number of themes, it is not possible for us to support that. The onus is on the user to customize their theme accordingly.
This plugin creates an the_subtitle()
template tag that can be used in your theme’s templates as follows:
if( function_exists( 'the_subtitle' ) ) the_subtitle();
You can wrap the string in some markup using the $before and $after parameters.
if( function_exists( 'the_subtitle' ) ) the_subtitle( '<h2 class="subtitle">', '</h2>' );
WooCommerce support
There is a small bridge plugin you can install and activate to automatically display the subtitle in most WooCommerce locations. This will work for all themes that are using WooCommerce’s default hooks.
NB: It’s known that the Ocean WP theme has it’s own hooks in the WooCommerce templates. You will need to alter the bridge plugin… please take a look at this support thread.
WPML Ready
KIA Subtitle has been tested by WPML and will allow you to translate the subtitle on multilingual sites.
Support
Support is handled in the WordPress forums. Please note that support is limited and does not cover any custom implementation of the plugin.
Please report any bugs, errors, warnings, code problems to Github
Screenshots
Installation
- Upload the
plugin
folder to the/wp-content/plugins/
directory - Activate the plugin through the ‘Plugins’ menu in WordPress
- Add the ‘the_subtitle()’ tag to your theme:
if(function_exists(‘the_subtitle’)) the_subtitle(); - if you need to ‘return’ the value, you can use
get_the_subtitle()
which accepts a$post_id
parameter if you need to use it outside the loop
if(function_exists(‘the_subtitle’)) $subtitle = get_the_subtitle( $post_id ); - As of version 1.2
the_subtitle
accepts 3 parameters:the_subtitle( $before = Null, $after = Null, $echo = True );
- As of version 1.3.4, there is a filter for
the_subtitle
FAQ
-
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;
}
}
add_filter(‘wp_title’,’kia_add_subtitle_to_wp_title’); -
Is this translation ready?
-
WPML now supports KIA Subtitle!
