What Are Custom Post Types in WordPress?

Built into WordPress is support for two default content types –

• Posts – For blog posts, news articles, stories.
• Pages – For individual pages, about us, contact, etc.

While these cover many common use cases, WordPress offers developers the ability to register completely custom post types beyond posts and pages.

Custom post types allow you to create specialized content items with their own data fields, display rules, and capabilities.

For example, some popular uses of custom post types include –

• Custom Content Sections – About us, Our Team, Testimonials etc
• Portfolios – For photographers, designers, architects etc.
• Products – For ecommerce sites and online stores.
• Listings – Real estate, job boards, directories etc.

The possibilities are endless! Custom post types unlock a whole new level of content flexibility in WordPress.

Why Use Custom Post Types?

Here are some of the key benefits of leveraging custom post types:

Organized Data – Group similar content together under a single post type. Keep your data structured logically for easier management.

Custom Fields – Attach specialized fields like images, relationships and other metadata to each post type.

Custom UI – Craft custom add/edit screens, columns and presentation for each post type in the admin.

Segmentation – Separate access and authorship for authors vs editors vs admin roles. Granular control over who can do what.

Going Beyond Posts and Pages – Posts and pages are just the tip of the iceberg. Custom post types let you model any kind of content in WordPress!

The core idea is this – if you find yourself cramming unrelated content into posts and pages…it’s time for a custom post type!

Ready to take the plunge? Let’s look at how to register and configure our own post types.

How to Create Custom Post Types in WordPress

The register_post_type() function allows us to define custom post types in WordPress. This function hooks into the init action and expects an array of configuration parameters.

Here is an example registration for a simple “Location” custom post type –

phpCopy codefunction create_location_cpt() {

  $labels = array(
    'name' => 'Locations',
    'singular_name' => 'Location'
  );

  $args = array(
    'labels' => $labels,
    'public' => true,
    'has_archive' => true,
  );

  register_post_type( 'location', $args );

}
add_action( 'init', 'create_location_cpt' );

Let’s break down what’s happening

• $labels defines the name for our post type shown in the admin UI
• $args contains our configuration parameters like visibility, archive etc.
• register_post_type() hooks it all together and registers the custom post type

This will register a basic “location” post type that behaves similar to posts and pages. But there’s so much more we can do with custom post types!

Here are some key configuration options you can use –

Post Type Parameters

• public – Make the post type visible publicly on the site or only show in the admin?
• exclude_from_search – Exclude posts from front-end search results?
• publicly_queryable – Allow querying for this post type via WP_Query() and REST API endpoints?
• has_archive – Enable post type archives at example.com/post-type

Admin and UI Labels

• label – General name for the post type
• labels – All UI text: Add New, Edit etc.
• description – Explanatory text seen in the admin.
• menu_icon – Custom dashicons icon for the admin menu

Capabilities and Permissions

• capability_type – granular permission types unique to the post type
• map_meta_cap – Enable specific capabilities like edit_location, read_location etc.

There are many more parameters you can customize! Refer to the register_post_type documentation for full details.

Example : Movie Custom Post Type in WordPress

Let’s see another example for registering a “Movies” custom post type –

phpCopy code// Register Movies Post Type
function create_movie_cpt() {

  $labels = array(
    'name'                  => _x( 'Movies', 'Post Type General Name', 'twentytwentytwo' ),
    'singular_name'         => _x( 'Movie', 'Post Type Singular Name', 'twentytwentytwo' ),
  );

  $args = array(
    'label'                 => __( 'Movies', 'twentytwentytwo' ),
    'description'           => __( 'Movie custom post type', 'twentytwentytwo' ),
    'labels'                => $labels,
    'supports'              => array( 'title', 'editor', 'thumbnail' ),
    'taxonomies'            => array( 'genres' ),
    'hierarchical'          => false,
    'public'                => true,
    'show_ui'               => true,
    'show_in_menu'          => true,
    'menu_position'         => 5,
    'show_in_admin_bar'     => true,
    'show_in_nav_menus'     => true,
    'can_export'            => true,
    'has_archive'           => true,
    'exclude_from_search'   => false,
    'publicly_queryable'    => true,
    'capability_type'       => 'page',
  );

  register_post_type( 'movie', $args );

}
add_action( 'init', 'create_movie_cpt', 0 );

This registers a more robust “Movies” post type with –

• Custom admin UI labels
• Editor support
• Featured images enabled
• Tied to a “Genres” taxonomy
• Granular capabilities and visibility settings

The possibilities are endless for crafting custom post types tailored to your needs!

Displaying Custom Post Types on Your WordPress Website

Once a custom post type is registered, you’ll see it as a menu item in the WordPress admin dashboard. You can add, edit, and manage posts just like with standard post types.

But how do you actually display these custom posts on the front-end?

There are several common ways to add custom post types to your WordPress site:

1. Single Post Pages

Use standard WordPress templates like single.php or create custom templates to display individual posts.

For example, single-movie.php could contain –

phpCopy code<?php
  get_header(); 

  if( have_posts() ) {
    while( have_posts() ) {
      the_post(); 
      // display post content
    }
  }

  get_footer();
?>

Per-post theming lets you fully customize the design on a post-by-post basis.

2. Archive Pages

Archive pages like example.com/movies let visitors browse all posts in a post type.

Use archive-{post-type}.php templates to customize archive views, or let WordPress handle it automatically.

3. Secondary Loops

Already displaying posts on a page? Add a new WP Query loop to show custom posts too –

phpCopy code// Main loop for regular posts 
if( have_posts() ) {
  while( have_posts() ) { 
    the_post();
    // ... 
  }
}

// Secondary loop for Movies
$movies = new WP_Query( array( 'post_type' => 'movie' ) );
if( $movies->have_posts() ) {
  while( $movies->have_posts() ) { 
    $movies->the_post();  
    // display movies
  }
}

wp_reset_postdata();

This keeps your main loop intact while injecting custom post types.

4. Custom Page Templates

For one-off landing pages and unique layouts, craft a custom page template to query and display custom posts. Useful for galleries, listings, and more.

5. The REST API

Modern sites can use the WordPress REST API to fetch post data as JSON for front-end frameworks like React, Angular etc. Custom post types are available at routes like /wp-json/wp/v2/movies.

WordPress makes it easy to surface custom post types across your site! Choose the display technique that fits your use case.

Enhancing Custom Post Types in WordPress with Custom Fields

The true power of custom post types shines through when you add custom fields and metadata.

While WordPress has endless plugin options for managing fields, let’s look at how you can programmatically add custom fields to a post type registration.

Defining Meta Fields

Use the register_meta() function to define custom fields on a per post type basis –

phpCopy code/**
 * Register meta boxes
 */
function movie_custom_fields() {

  register_meta( 'movie', 'imdb_rating', array(
    'type' => 'string',
    'single' => true,
    'show_in_rest' => true,
  ) );

  register_meta( 'movie', 'gallery_images', array(
    'type' => 'array',
    'single' => false,
    'show_in_rest' => true,
  ) );

}
add_action( 'init', 'movie_custom_fields' );

This adds an “IMDB Rating” text field and a “Gallery Images” set of images to movies.

You can declare any number of custom fields – numeric values, text, arrays, etc. Lots of flexibility!

Displaying Meta Fields

To show these new fields in the admin UI, hook into add_meta_boxes –

phpCopy code/**
 * Meta field display
 */ 
function movie_meta_boxes() {

  add_meta_box( 
    'imdb_meta',
    __( 'IMDB Rating', 'mytheme' ),
    'display_imdb_rating',
    'movie'
  );

  add_meta_box(
    'gallery_meta',
    __( 'Image Gallery', 'mytheme' ),
    'display_image_gallery', 
    'movie'
  );

}
add_action( 'add_meta_boxes', 'movie_meta_boxes' );

This adds the registered meta fields as metaboxes in the edit screen. Define custom rendering functions like display_imdb_rating() to populate the metaboxes.

To access values, use get_post_meta()–

phpCopy code$rating = get_post_meta( $post->ID, 'imdb_rating', true );

Custom fields add limitless possibilities for customizing post types!

Organizing Custom Post Types in WordPress with Taxonomies

The custom post possibilities expand even further when you add custom taxonomies.

Taxonomies like categories and tags allow grouping and filtering posts. We can register custom taxonomies and attach them to custom post types.

For example, adding a “Genre” taxonomy for movies –

phpCopy code// Register Genre taxonomy 
function movie_taxonomy() {

  $labels = array(
    'name' => _x( 'Genres', 'taxonomy general name' ),
    // ...
  );  

  register_taxonomy( 'genre', array('movie'), array(
    'labels' => $labels,
     // ... 
  ) );

}
add_action( 'init', 'movie_taxonomy', 0 );

Now visits can browse movies by genre, filtered by taxonomy terms.

Custom taxonomies open up new organization and classification potential!

Real-World Examples and Use Cases of Custom Post Types in WordPress

Let’s explore some common examples of custom post types in action –

1. Portfolio Post Types

Photographers, designers, and creatives often benefit from a custom “Portfolio” post type to showcase projects.

Key fields could include –

• Featured image
• External project link
• Client name
• Services offered

Portfolio items can display in styled grids on portfolio pages or via taxonomy/category filtering.

2. Product Post Types

Ecommerce sites need a products system. Custom post types like “product” or “download” provide an alternative to complex products plugins.

Key product fields may include –

• Price
• Stock level
• Weight
• Dimensions
• Photos
• SKU
• etc.

Tie products to taxonomies like product categories, tags, shipping classes etc. Offer product focused capabilities like managing stock.

3. Job Listings

Job boards and directories use post types to list openings. Useful fields could be –

• Company
• Location
• Salary
• Requirements
• Job type

Taxonomies like departments, seniority, and job location power browsing and filtering.

4. Reviews Post Type

Sites collecting user reviews may create a “Review” post type. Fields like –

• Rating
• Review text
• Author
• Product/location/entity reviewed

Provide great flexibility for gathering UGC.

These are just a few examples of leveraging custom post types! There are infinite possibilities for modeling custom content with WordPress.
