/** * Creates or modifies a taxonomy object. * * Note: Do not use before the {@see 'init'} hook. * * A simple function for creating or modifying a taxonomy object based on the * parameters given. The function will accept an array (third optional * parameter), along with strings for the taxonomy name and another string for * the object type. * * @since 2.3.0 * @since 4.2.0 Introduced `show_in_quick_edit` argument. * @since 4.4.0 The `show_ui` argument is now enforced on the term editing screen. * @since 4.4.0 The `public` argument now controls whether the taxonomy can be queried on the front end. * @since 4.5.0 Introduced `publicly_queryable` argument. * @since 4.7.0 Introduced `show_in_rest`, 'rest_base' and 'rest_controller_class' * arguments to register the Taxonomy in REST API. * * @global array $wp_taxonomies Registered taxonomies. * * @param string $taxonomy Taxonomy key, must not exceed 32 characters. * @param array|string $object_type Object type or array of object types with which the taxonomy should be associated. * @param array|string $args { * Optional. Array or query string of arguments for registering a taxonomy. * * @type array $labels An array of labels for this taxonomy. By default, Tag labels are * used for non-hierarchical taxonomies, and Category labels are used * for hierarchical taxonomies. See accepted values in * get_taxonomy_labels(). Default empty array. * @type string $description A short descriptive summary of what the taxonomy is for. Default empty. * @type bool $public Whether a taxonomy is intended for use publicly either via * the admin interface or by front-end users. The default settings * of `$publicly_queryable`, `$show_ui`, and `$show_in_nav_menus` * are inherited from `$public`. * @type bool $publicly_queryable Whether the taxonomy is publicly queryable. * If not set, the default is inherited from `$public` * @type bool $hierarchical Whether the taxonomy is hierarchical. Default false. * @type bool $show_ui Whether to generate and allow a UI for managing terms in this taxonomy in * the admin. If not set, the default is inherited from `$public` * (default true). * @type bool $show_in_menu Whether to show the taxonomy in the admin menu. If true, the taxonomy is * shown as a submenu of the object type menu. If false, no menu is shown. * `$show_ui` must be true. If not set, default is inherited from `$show_ui` * (default true). * @type bool $show_in_nav_menus Makes this taxonomy available for selection in navigation menus. If not * set, the default is inherited from `$public` (default true). * @type bool $show_in_rest Whether to include the taxonomy in the REST API. * @type string $rest_base To change the base url of REST API route. Default is $taxonomy. * @type string $rest_controller_class REST API Controller class name. Default is 'WP_REST_Terms_Controller'. * @type bool $show_tagcloud Whether to list the taxonomy in the Tag Cloud Widget controls. If not set, * the default is inherited from `$show_ui` (default true). * @type bool $show_in_quick_edit Whether to show the taxonomy in the quick/bulk edit panel. It not set, * the default is inherited from `$show_ui` (default true). * @type bool $show_admin_column Whether to display a column for the taxonomy on its post type listing * screens. Default false. * @type bool|callable $meta_box_cb Provide a callback function for the meta box display. If not set, * post_categories_meta_box() is used for hierarchical taxonomies, and * post_tags_meta_box() is used for non-hierarchical. If false, no meta * box is shown. * @type array $capabilities { * Array of capabilities for this taxonomy. * * @type string $manage_terms Default 'manage_categories'. * @type string $edit_terms Default 'manage_categories'. * @type string $delete_terms Default 'manage_categories'. * @type string $assign_terms Default 'edit_posts'. * } * @type bool|array $rewrite { * Triggers the handling of rewrites for this taxonomy. Default true, using $taxonomy as slug. To prevent * rewrite, set to false. To specify rewrite rules, an array can be passed with any of these keys: * * @type string $slug Customize the permastruct slug. Default `$taxonomy` key. * @type bool $with_front Should the permastruct be prepended with WP_Rewrite::$front. Default true. * @type bool $hierarchical Either hierarchical rewrite tag or not. Default false. * @type int $ep_mask Assign an endpoint mask. Default `EP_NONE`. * } * @type string $query_var Sets the query var key for this taxonomy. Default `$taxonomy` key. If * false, a taxonomy cannot be loaded at `?{query_var}={term_slug}`. If a * string, the query `?{query_var}={term_slug}` will be valid. * @type callable $update_count_callback Works much like a hook, in that it will be called when the count is * updated. Default _update_post_term_count() for taxonomies attached * to post types, which confirms that the objects are published before * counting them. Default _update_generic_term_count() for taxonomies * attached to other object types, such as users. * @type bool $_builtin This taxonomy is a "built-in" taxonomy. INTERNAL USE ONLY! * Default false. * } * @return WP_Error|void WP_Error, if errors. */ function register_taxonomy($taxonomy, $object_type, $args = array()) { global $wp_taxonomies; if (!is_array($wp_taxonomies)) { $wp_taxonomies = array(); } $args = wp_parse_args($args); if (empty($taxonomy) || strlen($taxonomy) > 32) { _doing_it_wrong(__FUNCTION__, __('Taxonomy names must be between 1 and 32 characters in length.'), '4.2.0'); return new WP_Error('taxonomy_length_invalid', __('Taxonomy names must be between 1 and 32 characters in length.')); } $taxonomy_object = new WP_Taxonomy($taxonomy, $object_type, $args); $taxonomy_object->add_rewrite_rules(); $wp_taxonomies[$taxonomy] = $taxonomy_object; $taxonomy_object->add_hooks(); /** * Fires after a taxonomy is registered. * * @since 3.3.0 * * @param string $taxonomy Taxonomy slug. * @param array|string $object_type Object type or array of object types. * @param array $args Array of taxonomy registration arguments. */ do_action('registered_taxonomy', $taxonomy, $object_type, (array) $taxonomy_object); }
