Register Taxonomy

Below is the code snippet in which we register a new Taxonomy for the Post.

add_action( 'init', 'prefix_register_taxonomy' );

function prefix_register_taxonomy() {
 
    $labels = array(
        'name'              => _x( 'My Taxonomies', 'taxonomy general name', 'textdomain' ),
        'singular_name'     => _x( 'My Taxonomy', 'taxonomy singular name', 'textdomain' ),
        'search_items'      => __( 'Search My Taxonomies', 'textdomain' ),
        'all_items'         => __( 'All My Taxonomies', 'textdomain' ),
