* share the same table, so therefore the functionality could apply to any one
* of them. It is then noted that while this function does not work on posts, it
* does not mean that it won't work on posts. It is recommended that you know
* what context you wish to retrieve the children of.
*
* Attachments may also be made the child of a post, so if that is an accurate
* statement (which needs to be verified), it would then be possible to get
* all of the attachments for a post. Attachments have since changed since
* version 2.5, so this is most likely inaccurate, but serves generally as an
* example of what is possible.
*
* The arguments listed as defaults are for this function and also of the
* get_posts() function. The arguments are combined with the get_children defaults
* and are then passed to the get_posts() function, which accepts additional arguments.
* You can replace the defaults in this function, listed below and the additional
* arguments listed in the get_posts() function.
*
* The 'post_parent' is the most important argument and important attention
* needs to be paid to the $args parameter. If you pass either an object or an
* integer (number), then just the 'post_parent' is grabbed and everything else
* is lost. If you don't specify any arguments, then it is assumed that you are
* in The Loop and the post parent will be grabbed for from the current post.
*
* The 'post_parent' argument is the ID to get the children. The 'numberposts'
* is the amount of posts to retrieve that has a default of '-1', which is
* used to get all of the posts. Giving a number higher than 0 will only
* retrieve that amount of posts.
*
* The 'post_type' and 'post_status' arguments can be used to choose what
* criteria of posts to retrieve. The 'post_type' can be anything, but WordPress
* post types are 'post', 'pages', and 'attachments'. The 'post_status'
* argument will accept any post status within the write administration panels.

* 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 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 $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' ) )`.
* 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'.
* }
* @return WP_Post_Type|WP_Error The registered post type object on success,
* WP_Error object on failure.

*
* The capability_type argument can optionally be registered as an array, with
* the first value being singular and the second plural, e.g. array('story, 'stories')
* Otherwise, an 's' will be added to the value for the plural form. After
* registration, capability_type will always be a string of the singular value.

*
* - edit_post, read_post, and delete_post are meta capabilities, which are then
* generally mapped to corresponding primitive capabilities depending on the
* context, which would be the post being edited/read/deleted and the user or
* role being checked. Thus these capabilities would generally not be granted
* directly to users or roles.
*
* - edit_posts - Controls whether objects of this post type can be edited.
* - edit_others_posts - Controls whether objects of this type owned by other users
* can be edited. If the post type does not support an author, then this will
* behave like edit_posts.
* - delete_posts - Controls whether objects of this post type can be deleted.
* - publish_posts - Controls publishing objects of this post type.
* - read_private_posts - Controls whether private objects can be read.
*
* These five primitive capabilities are checked in core in various locations.
* There are also six other primitive capabilities which are not referenced
* directly in core, except in map_meta_cap(), which takes the three aforementioned
* meta capabilities and translates them into one or more primitive capabilities
* that must then be checked against the user or role, depending on the context.
*
* - read - Controls whether objects of this post type can be read.
* - delete_private_posts - Controls whether private objects can be deleted.
* - delete_published_posts - Controls whether published objects can be deleted.
* - delete_others_posts - Controls whether objects owned by other users can be
* can be deleted. If the post type does not support an author, then this will
* behave like delete_posts.
* - edit_private_posts - Controls whether private objects can be edited.
* - edit_published_posts - Controls whether published objects can be edited.
*
* These additional capabilities are only used in map_meta_cap(). Thus, they are
* only assigned by default if the post type is registered with the 'map_meta_cap'
* argument set to true (default is false).

* Registers support of certain features for a post type.

* All core features are directly associated with a functional area of the edit
* screen, such as the editor or a meta box. 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 third, optional parameter can also be passed along with a feature to provide
* additional information about supporting that feature.
*
* Example usage:
*
* add_post_type_support( 'my_post_type', 'comments' );
* add_post_type_support( 'my_post_type', array(
* 'author', 'excerpt',
* ) );
* add_post_type_support( 'my_post_type', 'my_feature', array(
* 'field' => 'value',
* ) );
