register_post_type
register_post_type ( $post_type, $args = array() )
Parameters:- (string) post_type Post type key. Must not exceed 20 characters and may only contain lowercase alphanumeric characters, dashes, and underscores. See sanitize_key().
- (array|string) args { Array or string of arguments for registering a post type. @type string $label Name of the post type shown in the menu. Usually plural. Default is value of $labels['name']. @type string[] $labels An array of labels for this post type. If not set, post labels are inherited for non-hierarchical types and page labels for hierarchical ones. See get_post_type_labels() for a full list of supported labels. @type string $description A short descriptive summary of what the post type is. Default empty. @type bool $public Whether a post type is intended for use publicly either via the admin interface or by front-end users. While the default settings of $exclude_from_search, $publicly_queryable, $show_ui, and $show_in_nav_menus are inherited from $public, each does not rely on this relationship and controls a very specific intention. Default false. @type bool $hierarchical Whether the post type is hierarchical (e.g. page). Default false. @type bool $exclude_from_search Whether to exclude posts with this post type from front end search results. Default is the opposite value of $public. @type bool $publicly_queryable Whether queries can be performed on the front end for the post type as part of parse_request(). Endpoints would include: * ?post_type={post_type_key} * ?{post_type_key}={single_post_slug} * ?{post_type_query_var}={single_post_slug} If not set, the default is inherited from $public. @type bool $show_ui Whether to generate and allow a UI for managing this post type in the admin. Default is value of $public. @type bool|string $show_in_menu Where to show the post type in the admin menu. To work, $show_ui must be true. If true, the post type is shown in its own top level menu. If false, no menu is shown. If a string of an existing top level menu ('tools.php' or 'edit.php?post_type=page', for example), the post type will be placed as a sub-menu of that. Default is value of $show_ui. @type bool $show_in_nav_menus Makes this post type available for selection in navigation menus. Default is value of $public. @type bool $show_in_admin_bar Makes this post type available via the admin bar. Default is value of $show_in_menu. @type bool $show_in_rest Whether to include the post type in the REST API. Set this to true for the post type to be available in the block editor. @type string $rest_base To change the base URL of REST API route. Default is $post_type. @type string $rest_namespace To change the namespace URL of REST API route. Default is wp/v2. @type string $rest_controller_class REST API controller class name. Default is 'WP_REST_Posts_Controller'. @type string|bool $autosave_rest_controller_class REST API controller class name. Default is 'WP_REST_Autosaves_Controller'. @type string|bool $revisions_rest_controller_class REST API controller class name. Default is 'WP_REST_Revisions_Controller'. @type bool $late_route_registration A flag to direct the REST API controllers for autosave / revisions should be registered before/after the post type controller. @type int $menu_position The position in the menu order the post type should appear. To work, $show_in_menu must be true. Default null (at the bottom). @type string $menu_icon The URL to the icon to be used for this menu. Pass a base64-encoded SVG using a data URI, which will be colored to match the color scheme -- this should begin with 'data:image/svg+xml;base64,'. Pass the name of a Dashicons helper class to use a font icon, e.g. 'dashicons-chart-pie'. Pass 'none' to leave div.wp-menu-image empty so an icon can be added via CSS. Defaults to use the posts icon. @type string|array $capability_type The string to use to build the read, edit, and delete capabilities. May be passed as an array to allow for alternative plurals when using this argument as a base to construct the capabilities, e.g. array('story', 'stories'). Default 'post'. @type string[] $capabilities Array of capabilities for this post type. $capability_type is used as a base to construct capabilities by default. See get_post_type_capabilities(). @type bool $map_meta_cap Whether to use the internal default meta capability handling. Default false. @type array|false $supports Core feature(s) the post type supports. Serves as an alias for calling add_post_type_support() directly. Core features include 'title', 'editor', 'comments', 'revisions', 'trackbacks', 'author', 'excerpt', 'page-attributes', 'thumbnail', 'custom-fields', and 'post-formats'. Additionally, the 'revisions' feature dictates whether the post type will store revisions, and the 'comments' feature dictates whether the comments count will show on the edit screen. A feature can also be specified as an array of arguments to provide additional information about supporting that feature. Example: `array( 'my_feature', array( 'field' => 'value' ) )`. If false, no features will be added. Default is an array containing 'title' and 'editor'. @type callable $register_meta_box_cb Provide a callback function that sets up the meta boxes for the edit form. Do remove_meta_box() and add_meta_box() calls in the callback. Default null. @type string[] $taxonomies An array of taxonomy identifiers that will be registered for the post type. Taxonomies can be registered later with register_taxonomy() or register_taxonomy_for_object_type(). Default empty array. @type bool|string $has_archive Whether there should be post type archives, or if a string, the archive slug to use. Will generate the proper rewrite rules if $rewrite is enabled. Default false. @type bool|array $rewrite { Triggers the handling of rewrites for this post type. To prevent rewrite, set to false. Defaults to true, using $post_type as slug. To specify rewrite rules, an array can be passed with any of these keys: @type string $slug Customize the permastruct slug. Defaults to $post_type key. @type bool $with_front Whether the permastruct should be prepended with WP_Rewrite::$front. Default true. @type bool $feeds Whether the feed permastruct should be built for this post type. Default is value of $has_archive. @type bool $pages Whether the permastruct should provide for pagination. Default true. @type int $ep_mask Endpoint mask to assign. If not specified and permalink_epmask is set, inherits from $permalink_epmask. If not specified and permalink_epmask is not set, defaults to EP_PERMALINK. } @type string|bool $query_var Sets the query_var key for this post type. Defaults to $post_type key. If false, a post type cannot be loaded at ?{query_var}={post_slug}. If specified as a string, the query ?{query_var_string}={post_slug} will be valid. @type bool $can_export Whether to allow this post type to be exported. Default true. @type bool $delete_with_user Whether to delete posts of this type when deleting a user. * If true, posts of this type belonging to the user will be moved to Trash when the user is deleted. * If false, posts of this type belonging to the user will *not* be trashed or deleted. * If not set (the default), posts are trashed if post type supports the 'author' feature. Otherwise posts are not trashed or deleted. Default null. @type array $template Array of blocks to use as the default initial state for an editor session. Each item should be an array containing block name and optional attributes. Default empty array. @type string|false $template_lock Whether the block template should be locked if $template is set. * If set to 'all', the user is unable to insert new blocks, move existing blocks and delete blocks. * If set to 'insert', the user is able to move existing blocks but is unable to insert new blocks and delete blocks. Default false. @type bool $_builtin FOR INTERNAL USE ONLY! True if this post type is a native or "built-in" post_type. Default false. @type string $_edit_link FOR INTERNAL USE ONLY! URL segment to use for edit link of this post type. Default 'post.php?post=%d'. }
Returns:- (WP_Post_Type|WP_Error) The registered post type object on success, WP_Error object on failure.

Description
Registers a post type.Note: Post type registrations should not be hooked before the
{@see 'init'} action. Also, any taxonomy connections should be
registered via the `$taxonomies` argument to ensure consistency
when hooks such as {@see 'parse_query'} or {@see 'pre_get_posts'}
are used.
Post types can support any number of built-in core features such
as meta boxes, custom fields, post thumbnails, post statuses,
comments, and more. See the `$supports` argument for a complete
list of supported features.
