Manually Creating Custom Taxonomies

Add the next code in your theme's purposes.php document or in a site-specific plugin (advisable) to create a hierarchical customized taxonomy like classes:

          //hook into the init motion and get in touch with create_book_taxonomies when it fires  add_action( 'init', 'create_topics_hierarchical_taxonomy', 0 );    //create a customized taxonomy identify it subjects in your posts    serve as create_topics_hierarchical_taxonomy() {    // Add new taxonomy, make it hierarchical like classes  //first do the translations section for GUI      $labels = array(      'identify' => _x( 'Topics', 'taxonomy normal identify' ),      'singular_name' => _x( 'Topic', 'taxonomy singular identify' ),      'search_items' =>  __( 'Search Topics' ),      'all_items' => __( 'All Topics' ),      'parent_item' => __( 'Parent Topic' ),      'parent_item_colon' => __( 'Parent Topic:' ),      'edit_item' => __( 'Edit Topic' ),       'update_item' => __( 'Update Topic' ),      'add_new_item' => __( 'Add New Topic' ),      'new_item_name' => __( 'New Topic Name' ),      'menu_name' => __( 'Topics' ),    ); 	    // Now sign up the taxonomy      register_taxonomy('subjects',array('put up'), array(      'hierarchical' => true,      'labels' => $labels,      'show_ui' => true,      'show_admin_column' => true,      'query_var' => true,      'rewrite' => array( 'slug' => 'subject' ),    ));    }

To create a non-hierarchical customized taxonomy like Tags, upload this code in your theme's purposes.php or in a site-specific plugin:

          //hook into the init motion and get in touch with create_topics_nonhierarchical_taxonomy when it fires    add_action( 'init', 'create_topics_nonhierarchical_taxonomy', 0 );    serve as create_topics_nonhierarchical_taxonomy() {    // Labels section for the GUI      $labels = array(      'identify' => _x( 'Topics', 'taxonomy normal identify' ),      'singular_name' => _x( 'Topic', 'taxonomy singular identify' ),      'search_items' =>  __( 'Search Topics' ),      'popular_items' => __( 'Popular Topics' ),      'all_items' => __( 'All Topics' ),      'parent_item' => null,      'parent_item_colon' => null,      'edit_item' => __( 'Edit Topic' ),       'update_item' => __( 'Update Topic' ),      'add_new_item' => __( 'Add New Topic' ),      'new_item_name' => __( 'New Topic Name' ),      'separate_items_with_commas' => __( 'Separate subjects with commas' ),      'add_or_remove_items' => __( 'Add or take away subjects' ),      'choose_from_most_used' => __( 'Choose from essentially the most used subjects' ),      'menu_name' => __( 'Topics' ),    );     // Now sign up the non-hierarchical taxonomy like tag      register_taxonomy('subjects','put up',array(      'hierarchical' => false,      'labels' => $labels,      'show_ui' => true,      'show_admin_column' => true,      'update_count_callback' => '_update_post_term_count',      'query_var' => true,      'rewrite' => array( 'slug' => 'subject' ),    ));  }

Notice the variation between two codes. Value for hierarchical argument is correct for category-like taxonomy and false for tags-like taxonomies. Also in the labels array for non-hierarchical tags-like taxonomy, now we have added null for parent_item and parent_item_colon arguments because of this that not anything shall be proven in the UI to create guardian merchandise.
