* `edit_post_{$field}` pairs with `edit_{$field}`
* `pre_post_{$field}` pairs with `pre_{$field}`
* `post_{$field}` pairs with `{$field}`
As the above pairs' docs are unnecessarily duplicative, the second sets of docs have been removed. Also, the "duplicates" are purposely not marked as such in this case as the hook names differ. Also remove `@deprecated` tags mistakenly left in in [28041].

|
|
* 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 unaccurate, but serves generally as an
|
|
* example of what is possible.
|
|
*
|
|
* The arguments listed as defaults are for this function and also of the
|
|
* {@link get_posts()} function. The arguments are combined with the
|
|
* get_children defaults and are then passed to the {@link get_posts()}
|
|
* function, which accepts additional arguments. You can replace the defaults in
|
|
* this function, listed below and the additional arguments listed in the
|
|
* {@link 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.
|
|
*
|
|
* @see get_posts() Has additional arguments that can be replaced.
|
|
* @internal Claims made in the long description might be inaccurate.

* - 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.
|
|
* * You can see accepted values in {@link get_post_type_labels()}.
|
|
* - description - A short descriptive summary of what the post type is. Defaults to blank.
|
|
* - public - Whether a post type is intended for use publicly either via the admin interface or by front-end users.
|
|
* * Defaults to false.
|
|
* * 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.
|
|
* - hierarchical - Whether the post type is hierarchical (e.g. page). Defaults to false.
|
|
* - exclude_from_search - Whether to exclude posts with this post type from front end search results.
|
|
* * If not set, the opposite of public's current value is used.
|
|
* - publicly_queryable - Whether queries can be performed on the front end for the post type as part of parse_request().
|
|
* * ?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.
|
|
* - show_ui - Whether to generate a default UI for managing this post type in the admin.
|
|
* * If not set, the default is inherited from public.
|
|
* - show_in_menu - Where to show the post type in the admin menu.
|
|
* * 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 (eg. 'tools.php' or 'edit.php?post_type=page'), the post type will
|
|
* be placed as a sub menu of that.
|
|
* * show_ui must be true.
|
|
* * If not set, the default is inherited from show_ui
|
|
* - show_in_nav_menus - Makes this post type available for selection in navigation menus.
|
|
* * If not set, the default is inherited from public.
|
|
* - show_in_admin_bar - Makes this post type available via the admin bar.
|
|
* * If not set, the default is inherited from show_in_menu
|
|
* - menu_position - The position in the menu order the post type should appear.
|
|
* * show_in_menu must be true
|
|
* * Defaults to null, which places it at the bottom of its area.
|
|
* - menu_icon - The url to the icon to be used for this menu. Defaults to use the posts icon.
|
|
* * 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.
|
|
* - capability_type - The string to use to build the read, edit, and delete capabilities. Defaults to 'post'.
|
|
* * 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').
|
|
* - capabilities - Array of capabilities for this post type.
|
|
* * By default the capability_type is used as a base to construct capabilities.
|
|
* * You can see accepted values in {@link get_post_type_capabilities()}.
|
|
* - map_meta_cap - Whether to use the internal default meta capability handling. Defaults to false.
|
|
* - supports - An alias for calling add_post_type_support() directly. Defaults to title and editor.
|
|
* * See {@link add_post_type_support()} for documentation.
|
|
* - 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.
|
|
* - taxonomies - An array of taxonomy identifiers that will be registered for the post type.
|
|
* * Default is no taxonomies.
|
|
* * Taxonomies can be registered later with register_taxonomy() or register_taxonomy_for_object_type().
|
|
* - has_archive - True to enable post type archives. Default is false.
|
|
* * Will generate the proper rewrite rules if rewrite is enabled.
|
|
* - rewrite - Triggers the handling of rewrites for this post type. Defaults to true, using $post_type as slug.
|
|
* * To prevent rewrite, set to false.
|
|
* * To specify rewrite rules, an array can be passed with any of these keys
|
|
* * 'slug' => string Customize the permastruct slug. Defaults to $post_type key
|
|
* * 'with_front' => bool Should the permastruct be prepended with WP_Rewrite::$front. Defaults to true.
|
|
* * 'feeds' => bool Should a feed permastruct be built for this post type. Inherits default from has_archive.
|
|
* * 'pages' => bool Should the permastruct provide for pagination. Defaults to true.
|
|
* * 'ep_mask' => const Assign an endpoint mask.
|
|
* * 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
|
|
* - 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.
|
|
* - can_export - Allows this post type to be exported. Defaults to true.
|
|
* - 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 then 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('author'). Otherwise posts are not trashed or deleted.
|
|
* - _builtin - true if this post type is a native or "built-in" post_type. THIS IS FOR INTERNAL USE ONLY!

/**
|
|
* Builds an object with all post type capabilities out of a post type object
|
|
*
|
|
* Post type capabilities use the 'capability_type' argument as a base, if the
|
|
* capability is not set in the 'capabilities' argument array or if the
|
|
* 'capabilities' argument is not supplied.
|
|
*
|
|
* 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.
|
|
*
|
|
* By default, seven keys are accepted as part of the capabilities array:
|
|
*
|
|
* - 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.
|
|
* - publish_posts - Controls publishing objects of this post type.
|
|
* - read_private_posts - Controls whether private objects can be read.
|
|
*
|
|
* These four primitive capabilities are checked in core in various locations.
|
|
* There are also seven 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_posts - Controls whether objects of this post type can be deleted.
|
|
* - 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).
