* Build an object with all post type capabilities out of a post type object

[1534] Fix | Delete

[1535] Fix | Delete

* Post type capabilities use the 'capability_type' argument as a base, if the

[1536] Fix | Delete

* capability is not set in the 'capabilities' argument array or if the

[1537] Fix | Delete

* 'capabilities' argument is not supplied.

[1538] Fix | Delete

*

[1539] Fix | Delete

* The capability_type argument can optionally be registered as an array, with

[1540] Fix | Delete

* the first value being singular and the second plural, e.g. array('story, 'stories')

[1541] Fix | Delete

* Otherwise, an 's' will be added to the value for the plural form. After

[1542] Fix | Delete

* registration, capability_type will always be a string of the singular value.

[1543] Fix | Delete

*

[1544] Fix | Delete

* By default, eight keys are accepted as part of the capabilities array:

[1545] Fix | Delete

*

[1546] Fix | Delete

* - edit_post, read_post, and delete_post are meta capabilities, which are then

[1547] Fix | Delete

* generally mapped to corresponding primitive capabilities depending on the

[1548] Fix | Delete

* context, which would be the post being edited/read/deleted and the user or

[1549] Fix | Delete

* role being checked. Thus these capabilities would generally not be granted

[1550] Fix | Delete

* directly to users or roles.

[1551] Fix | Delete

*

[1552] Fix | Delete

* - edit_posts - Controls whether objects of this post type can be edited.

[1553] Fix | Delete

* - edit_others_posts - Controls whether objects of this type owned by other users

[1554] Fix | Delete

* can be edited. If the post type does not support an author, then this will

[1555] Fix | Delete

* behave like edit_posts.

[1556] Fix | Delete

* - delete_posts - Controls whether objects of this post type can be deleted.

[1557] Fix | Delete

* - publish_posts - Controls publishing objects of this post type.

[1558] Fix | Delete

* - read_private_posts - Controls whether private objects can be read.

[1559] Fix | Delete

*

[1560] Fix | Delete

* These five primitive capabilities are checked in core in various locations.

[1561] Fix | Delete

* There are also six other primitive capabilities which are not referenced

[1562] Fix | Delete

* directly in core, except in map_meta_cap(), which takes the three aforementioned

[1563] Fix | Delete

* meta capabilities and translates them into one or more primitive capabilities

[1564] Fix | Delete

* that must then be checked against the user or role, depending on the context.

[1565] Fix | Delete

*

[1566] Fix | Delete

* - read - Controls whether objects of this post type can be read.

[1567] Fix | Delete

* - delete_private_posts - Controls whether private objects can be deleted.

[1568] Fix | Delete

* - delete_published_posts - Controls whether published objects can be deleted.

[1569] Fix | Delete

* - delete_others_posts - Controls whether objects owned by other users can be

[1570] Fix | Delete

* can be deleted. If the post type does not support an author, then this will

[1571] Fix | Delete

* behave like delete_posts.

[1572] Fix | Delete

* - edit_private_posts - Controls whether private objects can be edited.

[1573] Fix | Delete

* - edit_published_posts - Controls whether published objects can be edited.

[1574] Fix | Delete

*

[1575] Fix | Delete

* These additional capabilities are only used in map_meta_cap(). Thus, they are

[1576] Fix | Delete

* only assigned by default if the post type is registered with the 'map_meta_cap'
