Creating custom post types and taxonomies in WordPress can be a powerful way to extend the functionality of the platform and create a more customized website. Custom post types allow you to create new types of content, such as portfolios, testimonials, or team member bios, while custom taxonomies allow you to organize and categorize that content in new ways.
To create a custom post type, you will first need to define it using the register_post_type function. This function allows you to set various parameters for your post type, such as its name, its labels, and its capabilities. Some important parameters to consider when creating your custom post type include:
- ‘labels’: This parameter sets the labels for your post type, such as the name to be used for the admin menu and the singular and plural versions of the name.
- ‘public’: This parameter sets whether the post type is visible to the public or not. If set to true, the post type will be visible on the front-end of the website and can be queried using the main loop.
- ‘supports’: This parameter sets the features that the post type will support, such as title, editor, thumbnail, and so on.
Once you have defined your custom post type, you will need to register it using the init action. This is typically done using the following code:
function create_my_custom_post_type() {
register_post_type( 'my-custom-post-type', $args );
}
add_action( 'init', 'create_my_custom_post_type' );
Creating custom taxonomies is similar to creating custom post types. You will need to define the taxonomy using the register_taxonomy function, and set various parameters, such as its name, its labels, and the post types it is associated with. Some important parameters to consider when creating your custom taxonomy include:
- ‘labels’: This parameter sets the labels for your taxonomy, such as the name to be used for the admin menu and the singular and plural versions of the name.
- ‘public’: This parameter sets whether the taxonomy is visible to the public or not. If set to true, the taxonomy will be visible on the front-end of the website and can be queried using the main loop.
- ‘hierarchical’: This parameter sets whether the taxonomy will have a parent-child relationship like categories or not like tags.
Once you have defined your custom taxonomy, you will need to register it using the init action, similar to custom post types.
function create_my_custom_taxonomy() {
register_taxonomy( 'my-custom-taxonomy', 'my-custom-post-type', $args );
}
add_action( 'init', 'create_my_custom_taxonomy' );
It is also possible to associate an existing taxonomy to a custom post type while registering it, by passing the parameter ‘taxonomies’ and the array of taxonomies.
Once your custom post types and taxonomies have been created, you will need to create templates to display them on the front-end of your website. WordPress uses a template hierarchy to determine which template to use to display a particular post type or taxonomy.
To create a custom template for your post type, you will need to create a new file with the name single-{post-type-name}.php and place it in your theme’s directory. For custom taxonomies, you will need to create a new file with the name taxonomy-{taxonomy-name}.php and place it in your theme’s directory. These templates will be used to display the single posts and archives for your custom post types and taxonomies respectively. In these templates, you will have access to all of the same template tags and functions that you would in a regular template, such as the loop and the get_header() and get_footer() functions. However, you will also need to use specialized template tags, such as the_title() and the_content() to display the custom fields of your custom post types and taxonomies. Additionally, you will need to create a code structure in the template that allows you to loop through and display all of the posts in your custom post type or taxonomy.
It’s worth noting that there are also various plugins available that can help you create custom post types and taxonomies. These can be a great starting point if you’re new to the process, but keep in mind that the code generated by these plugins may not be as clean or efficient as code that you write yourself.
When creating custom post types and taxonomies, it’s also important to consider the user experience. For example, you’ll want to create clear and meaningful labels for your custom post types and taxonomies, as well as make sure that they’re easy to navigate and understand.
One thing to keep in mind when creating custom post types and taxonomies is that they don’t automatically show up in your site’s navigation menus. To add them to your navigation, you’ll need to use the register_nav_menus function to create a new menu location, and then use the wp_nav_menu function to output the menu in your theme.
Another important aspect to consider is custom fields, with the use of Custom Fields you can add custom data to your post type and taxonomy, it can give you a lot of versatility and flexibility when you’re creating your custom post type or taxonomy.
When creating custom post types and taxonomies, it’s also important to keep in mind the SEO implications. Be sure to use appropriate titles, meta descriptions, and header tags on your custom post type and taxonomy pages to help improve your site’s visibility in search engines.
It’s also worth noting that there are many plugins available for adding extra functionality and features to your custom post types and taxonomies. These can include things like custom fields, custom templates, and more.
Finally, keep in mind that custom post types and taxonomies can be a bit tricky to work with, especially if you’re new to WordPress development.

In conclusion, creating custom post types and taxonomies can be a powerful way to add new functionality to your WordPress site.
