How to Create Custom Taxonomy with Custom Post Types in WordPress

Published on : April 16,2023

Custom taxonomies are a powerful feature in WordPress that allow you to group and organize your content in meaningful ways. When combined with custom post types, custom taxonomies can help you create a highly organized and efficient website. Here is a step-by-step guide on how to create a custom taxonomy for your custom post type in WordPress:

Plan your custom taxonomy: Before you start coding, determine what type of content you want to group with your custom taxonomy. You will need to decide on the name of the taxonomy, the labels, and any custom fields or terms that are needed.
Register the custom taxonomy: In your functions.php file, add the following code to register your custom taxonomy:

function custom_taxonomy() {
    $labels = array(
        'name' => __( 'Custom Taxonomy Name' ),
        'singular_name' => __( 'Custom Taxonomy Singular Name' ),
        'search_items' => __( 'Search Custom Taxonomy' ),
        'all_items' => __( 'All Custom Taxonomy' ),
        'parent_item' => __( 'Parent Custom Taxonomy' ),
        'parent_item_colon' => __( 'Parent Custom Taxonomy:' ),
        'edit_item' => __( 'Edit Custom Taxonomy' ),
        'update_item' => __( 'Update Custom Taxonomy' ),
        'add_new_item' => __( 'Add New Custom Taxonomy' ),
        'new_item_name' => __( 'New Custom Taxonomy Name' ),
        'menu_name' => __( 'Custom Taxonomy' ),
    );

    $args = array(
        'labels' => $labels,
        'hierarchical' => true,
        'show_ui' => true,
        'show_admin_column' => true,
        'query_var' => true,
        'rewrite' => array( 'slug' => 'custom-taxonomy' ),
    );

    register_taxonomy( 'custom_taxonomy_name', array( 'custom_post_type_name' ), $args );
}
add_action( 'init', 'custom_taxonomy' );

Replace 'Custom Taxonomy Name', 'Custom Taxonomy Singular Name', and 'Custom Taxonomy' with the desired labels. Replace 'custom_taxonomy_name' with a unique name for your custom taxonomy, and replace 'custom_post_type_name' with the name of your custom post type.

Add custom terms: To add custom terms to your custom taxonomy, go to Posts > Custom Taxonomy in your WordPress dashboard. Here, you can create new terms and assign them to your custom post type.
Display the custom taxonomy: To display your custom taxonomy on your website, you will need to modify the template file for your custom post type. Add the following code to your template file where you want to display the custom taxonomy:

<?php the_terms( $post->ID, 'custom_taxonomy_name', '<div class="custom-taxonomy">', ', ', '</div>' ); ?>

Replace 'custom_taxonomy_name' with the name of your custom taxonomy.

Test the custom taxonomy: Once you have created your custom taxonomy, add some content to your custom post type and test the custom taxonomy to make sure it works as expected.

Creating a custom taxonomy for your custom post type can help you organize your content and make it easier for users to find what they're looking for on your website. With a bit of planning and coding, you can create a custom taxonomy that adds value to your website and enhances the user experience.
