Hey there! If you‘re reading this, you probably know a thing or two about WordPress. But even experienced WordPress users can get tripped up by post types. What exactly are they? How do they work? And how can you use them to build better, more powerful websites?
Don‘t worry, I‘ve got you covered. As a WordPress developer, I‘ve worked with post types for years, and I‘m here to give you the complete lowdown. By the end of this guide, you‘ll be a post type pro, ready to harness their power for your own sites. Let‘s dive in!
What is a Post Type in WordPress?
At its core, a post type in WordPress is a way to categorize and structure your content. WordPress started as a blogging platform, so originally there was just one type of content – posts. But as WordPress grew into a full content management system (CMS), the need for different types of content emerged.
That‘s where post types come in. WordPress now provides a way to define different "types" of content, each with its own characteristics, data fields, and display templates.
By default, WordPress comes with five built-in post types:
- Posts – the default type for blog posts or news articles
- Pages – for static content like your About or Contact pages
- Attachments – for media files like images or documents
- Revisions – stores previous versions of your posts or pages
- Navigation Menus – for creating menus
But the real power comes with custom post types – post types that you define yourself to fit the unique needs of your site.
Why Use Custom Post Types?
Custom post types are a game-changer for WordPress sites. They let you transform WordPress from a simple blog into a complex content management system tailored to your exact needs.
Let‘s look at an example. Say you‘re building a site for a real estate company. With custom post types, you could create a "Property" post type to store all the details for each listing: price, square footage, number of bedrooms, location, amenities, photos, and more. Each property listing would be its own separate piece of content, with its own URL and page on the site.
Then, you could create custom category and tag taxonomies to organize the properties by type (condo, house, apartment), location, price range, and more. You could even create custom search filters to let visitors narrow down properties by their specific criteria.
With this setup, managing property listings becomes a breeze. Agents can easily add new listings, update details, and keep everything organized. And visitors can browse, search, and filter properties in intuitive ways.
That‘s just one example – custom post types can adapt to any type of site or content. Here are a few more examples:
- A food blog could use a "Recipe" post type to structure each recipe with fields for ingredients, directions, cook time, and nutrition facts.
- A movie database could use a "Movie" post type with fields for title, director, release year, cast, runtime, and genre.
- An event calendar could use an "Event" post type with fields for date, time, location, ticket price, and description.
The possibilities are endless! If you can dream up a type of content, chances are you can build it with a custom post type.
Creating Custom Post Types
Okay, so custom post types sound amazing. But how do you actually create them in WordPress?
There are two main approaches:
- Registering the post type in code (either in your theme‘s functions.php file or in a plugin)
- Using a plugin with a user interface for creating post types
If you‘re comfortable with PHP and WordPress development, registering your post types in code gives you the most control and flexibility. Here‘s a basic example of registering a "Movie" post type:
function create_movie_post_type() {
register_post_type(‘movie‘,
array(
‘labels‘ => array(
‘name‘ => __(‘Movies‘),
‘singular_name‘ => __(‘Movie‘)
),
‘public‘ => true,
‘has_archive‘ => true,
‘supports‘ => array(‘title‘, ‘editor‘, ‘thumbnail‘, ‘excerpt‘, ‘comments‘),
‘rewrite‘ => array(‘slug‘ => ‘movies‘),
)
);
}
add_action(‘init‘, ‘create_movie_post_type‘);This code defines a new "movie" post type with various settings and capabilities. You can customize the labels, slugs, supported features, and more.
If you‘re not comfortable with code, there are several popular plugins that provide a user interface for creating custom post types:
- Custom Post Type UI – a free plugin with over 1 million active installs
- Pods – a powerful free plugin for creating post types and custom fields
- Toolset Types – a premium plugin for creating post types, custom fields, and taxonomies
- Advanced Custom Fields (ACF) – while primarily for custom fields, ACF also supports creating post types
These plugins make it easy to create post types without writing any code.
Custom Taxonomies
In addition to custom post types, WordPress also supports custom taxonomies. Taxonomies are ways to group and classify post types.
WordPress has two built-in taxonomies that you‘re probably familiar with:
- Categories – a hierarchical taxonomy, meaning categories can have parent and child relationships
- Tags – a flat taxonomy, where all tags are on the same level
But just like with post types, you can also register your own custom taxonomies to organize your post types in custom ways.
For example, for a "Movie" post type, you might want taxonomies for:
- Genre (Action, Comedy, Drama, etc.)
- Director
- Actor
- Year
Here‘s an example of registering a "Genre" taxonomy for the "Movie" post type:
function create_genre_taxonomy() {
register_taxonomy(
‘genre‘,
‘movie‘,
array(
‘label‘ => __(‘Genres‘),
‘hierarchical‘ => true,
)
);
}
add_action(‘init‘, ‘create_genre_taxonomy‘);This code creates a new "Genre" taxonomy and associates it with the "Movie" post type. The hierarchical parameter set to true means it will behave like categories, with the ability to have parent-child relationships.
Custom taxonomies give you even more flexibility to structure and organize your content in meaningful ways.
Custom Fields
Another key feature that pairs perfectly with custom post types is custom fields. Custom fields let you store additional structured data for each post.
Going back to our "Movie" post type example, we might want to store data like:
- Director
- Release Year
- Running Time
- Movie Poster Image
- IMDb Rating
- Budget
- Box Office Earnings
WordPress has a built-in custom fields feature, but it‘s quite basic. Many developers choose to use a plugin like Advanced Custom Fields (ACF) for a more powerful and user-friendly custom field solution.
With ACF, you can create different field groups for each post type and arrange them on the post editing screen. It supports a wide variety of field types:
- Text
- Number
- URL
- Password
- Textarea
- WYSIWYG Editor
- Image
- File
- Select
- Checkbox
- Radio Button
- True/False
- Post Object
- Page Link
- Relationship
- Taxonomy
- User
- Google Map
- Date Picker
- Color Picker
- and more
Here‘s an example of what a custom field setup for our "Movie" post type might look like in ACF:
With these fields, we can capture all sorts of rich metadata for each movie. We can then display this data in custom templates on the front-end of the site.
Displaying Custom Post Types
Once you have your custom post types, taxonomies, and fields set up, you need a way to display them on your site. WordPress provides a few key ways to do this:
Single Post Templates – WordPress will look for a template file in your theme specific to the post type (e.g. single-movie.php for a "movie" post type) to display individual post pages.
Archive Templates – WordPress can also auto-generate archive pages for each post type that display a list of all posts. You can create a custom archive template (e.g. archive-movie.php) to control how this list is displayed.
Custom Queries – For the most control, developers can use the
WP_Queryclass to fetch posts programmatically. This lets you display posts anywhere on your site and customize the query parameters.
Here‘s an example of a custom query to fetch and display a list of "Movie" posts:
$args = array(
‘post_type‘ => ‘movie‘,
‘posts_per_page‘ => 10,
‘orderby‘ => ‘meta_value_num‘,
‘meta_key‘ => ‘imdb_rating‘,
‘order‘ => ‘DESC‘
);
$movie_query = new WP_Query($args);
if ($movie_query->have_posts()) {
while ($movie_query->have_posts()) {
$movie_query->the_post();
// Display fields for each movie
the_title();
the_field(‘release_year‘);
the_field(‘director‘);
// etc.
}
wp_reset_postdata();
}This query fetches the 10 "Movie" posts with the highest IMDb rating. Inside the loop, we can display the various fields we set up for each movie.
For even more control, you can also use hooks and filters to modify the query and display of your post types at a granular level.
Real-World Examples
To really appreciate the power of custom post types, let‘s look at a few real-world examples of complex sites built with WordPress and custom post types:
- TechCrunch uses custom post types for different content categories like "Startups", "Fundings & Exits", "Apps", and "Reviews".
- The New Yorker uses post types for "Articles", "Books", "Cartoons", "Humor", and more.
- AllRecipes structures their 1000s of recipes with a "Recipe" post type.
- SitePoint uses post types for "Articles", "Books", "Courses", and "Premium" (paywalled content).
- IMDb uses post types for "Movies", "TV Shows", "Cast & Crew", "Companies", and more.
These are just a few examples, but they demonstrate how custom post types can adapt WordPress to manage all sorts of complex, structured content.
