Introduces `is_post_status_viewable()` as a sibling to `is_post_type_viewable()`. Internal and protected statuses are never considered viewable. For built in posts statuses the `public` attribute is checked, for custom statuses the `publicly_queryable` attribute is checked. Introduces `is_post_publicly_viewable()` for determining if an individual post can be viewed by logged out users. A post is considered viewable if both `is_post_status_viewable()` and `is_post_type_viewable()` return `true` for the post's attributes. Additionally modifies `is_post_type_viewable()` to return `false` if an unregistered post type is passed to the function to avoid attempting to access properties on a non-object. Props peterwilsoncc, SergeyBiryukov, whyisjake, TimothyBlynJacobs. Fixes #49380.

|

* share the same table, so therefore the functionality could apply to any one

|
||
* 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.

* admin. Default is value of $public.

* $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
|
||

|

* '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.
|

|
||
* Default is an array containing 'title' and 'editor'.
|
||

* edit form. Do remove_meta_box() and add_meta_box() calls in the

|
||
*
|
||
* @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_string}={post_slug} will be valid.
|

|

|
||
* to Trash when the user is deleted.
|
||
* - If false, posts of this type belonging to the user will *not*

|
||
* - 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.

|
||
* 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.
