How to Create Custom Taxonomies in WordPress

Creating Custom Taxonomies in WordPress

Custom taxonomies in WordPress allow you to classify your content in a more meaningful way beyond categories and tags. This can be particularly useful when organizing different types of content on your website.

To create a custom taxonomy in WordPress, you can use the register_taxonomy function. Here’s an example of how you can create a custom taxonomy called “Books” for your WordPress site:

function flashify_custom_taxonomy() {
    $labels = array(
        'name'              => _x( 'Books', 'taxonomy general name' ),
        'singular_name'     => _x( 'Book', 'taxonomy singular name' ),
        'search_items'      => __( 'Search Books' ),
        'all_items'         => __( 'All Books' ),
        'edit_item'         => __( 'Edit Book' ),
        'update_item'       => __( 'Update Book' ),
        'add_new_item'      => __( 'Add New Book' ),
        'new_item_name'     => __( 'New Book Name' ),
        'menu_name'         => __( 'Books' ),
    );

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

    register_taxonomy( 'books', array( 'post' ), $args );
}
add_action( 'init', 'flashify_custom_taxonomy' );

This code snippet defines a custom taxonomy named “Books” with the necessary labels and settings. You can customize the labels and settings as needed for your specific use case.

After adding this code to your theme’s functions.php file or a custom plugin, you can now assign the “Books” taxonomy to your posts or custom post types. When you edit a post, you’ll see the “Books” taxonomy box where you can select the appropriate terms.

Custom taxonomies are a powerful feature in WordPress that can help you better organize and structure your content. By creating custom taxonomies, you can provide a more intuitive way for users to navigate and filter your content based on specific criteria.
