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.

See the wiki for full documentation.

Note that Extended Taxonomies was merged into this library with version 4.0. There's now no need to use the separate Extended Taxonomies library.

Improved Defaults for Post Types

  • Automatically generated labels and post updated messages
  • Public post type with admin UI enabled
  • Hierarchical with page capability type
  • Support for post thumbnails
  • Optimal admin menu placement

Improved Defaults for Taxonomies

  • Automatically generated labels and term updated messages
  • Hierarchical public taxonomy with admin UI enabled

Extended Admin Features

  • Ridiculously easy custom columns on the post type listing screen:
    • Columns for post meta, taxonomy terms, featured images, post fields, Posts 2 Posts connections, and callback functions
    • Sortable columns for post meta, taxonomy terms, and post fields
    • User capability restrictions
    • Default sort column and sort order
  • Ridiculously easy custom columns on the term listing screen:
    • Columns available for term meta and callback functions
    • User capability restrictions
  • Filter controls on the post type listing screen to enable filtering by post meta and taxonomy terms
  • Override the 'Featured Image' and 'Enter title here' text
  • Several custom meta boxes available for taxonomies on the post editing screen:
    • A simplified list of checkboxes
    • Radio inputs
    • A dropdown menu
    • Or a callback function
  • Post types and taxonomies automatically added to the 'At a Glance' section on the dashboard

Extended Front-end Features for Post Types

  • Specify a custom permalink structure:
    • For example reviews/%year%/%month%/%review%
    • Supports all relevant rewrite tags including dates and custom taxonomies
    • Automatic integration with the Rewrite Rule Testing plugin
  • Specify public query vars which enable filtering by post meta
  • Specify public query vars which enable sorting by post meta, taxonomy terms, and post fields
  • Override public or private query vars such as posts_per_page, orderby, order, and nopaging
  • Add the post type to the site's main RSS feed

Minimum Requirements

PHP: 7.0
WordPress: 4.8

Installation

Extended CPTs is a developer library, not a plugin, which means you need to include it somewhere in your own project. You can use Composer:

composer require johnbillion/extended-cpts

Or you can download the library and include it manually:

require_once 'extended-cpts/extended-cpts.php';

Usage

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', 'post' );
} );

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'       => 'Published',
				'meta_key'    => 'published_date',
				'date_format' => 'd/m/Y'
			],
			'story_genre' => [
				'taxonomy' => 'genre'
			],
		],

		# Add a dropdown filter 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'       => '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.
