Extended CPTs

Extended CPTs is a library which provides extended functionality to WordPress custom post types and taxonomies. This allows developers to quickly build post types and taxonomies without having to write the same code again and again.

Extended CPTs works with both the block editor and the classic editor.

See the wiki for full documentation.

Minimum Requirements

  • PHP: 7.4
    • PHP 8.0 and 8.1 are supported
  • WordPress: 5.6
    • Tested up to WP 6.1

Extended CPTs should work with versions of WordPress back to 4.9 but these versions are not tested and not officially supported.


Extended CPTs is a developer library, not a plugin, which means you need to include it as a dependency in your project. Install it using Composer:

composer require johnbillion/extended-cpts

Other means of installation or usage, particularly bundling within a plugin, is not officially supported and done at your own risk.


Need a simple post type with no frills? You can register a post type with a single parameter:

add_action( 'init', function() {
	register_extended_post_type( 'article' );
} );

And you can register a taxonomy with just two parameters:

add_action( 'init', function() {
	register_extended_taxonomy( 'location', 'article' );
} );

Try it. You'll have a hierarchical public post type with an admin UI, a hierarchical public taxonomy with an admin UI, and all the labels and updated messages for them will be automatically generated.

Or for a bit more functionality:

add_action( 'init', function() {
	register_extended_post_type( 'story', [

		# Add the post type to the site's main RSS feed:
		'show_in_feed' => true,

		# Show all posts on the post type archive:
		'archive' => [
			'nopaging' => true,

		# Add some custom columns to the admin screen:
		'admin_cols' => [
			'story_featured_image' => [
				'title'          => 'Illustration',
				'featured_image' => 'thumbnail'
			'story_published' => [
				'title_icon'  => 'dashicons-calendar-alt',
				'meta_key'    => 'published_date',
				'date_format' => 'd/m/Y'
			'story_genre' => [
				'taxonomy' => 'genre'

		# Add some dropdown filters to the admin screen:
		'admin_filters' => [
			'story_genre' => [
				'taxonomy' => 'genre'
			'story_rating' => [
				'meta_key' => 'star_rating',

	], [

		# Override the base names used for labels:
		'singular' => 'Story',
		'plural'   => 'Stories',
		'slug'     => 'stories',

	] );

	register_extended_taxonomy( 'genre', 'story', [

		# Use radio buttons in the meta box for this taxonomy on the post editing screen:
		'meta_box' => 'radio',

		# Add a custom column to the admin screen:
		'admin_cols' => [
			'updated' => [
				'title_cb'    => function() {
					return '<em>Last</em> Updated';
				'meta_key'    => 'updated_date',
				'date_format' => 'd/m/Y'

	] );
} );

Bam, we now have:

  • A 'Stories' post type, with correctly generated labels and post updated messages, three custom columns in the admin area (two of which are sortable), stories added to the main RSS feed, and all stories displayed on the post type archive.
  • A 'Genre' taxonomy attached to the 'Stories' post type, with correctly generated labels and term updated messages, and a custom column in the admin area.

The register_extended_post_type() and register_extended_taxonomy() functions are ultimately wrappers for the register_post_type() and register_taxonomy() functions in WordPress core, so any of the parameters from those functions can be used.

There's quite a bit more you can do. See the wiki for full documentation.
