260 |
* get_children defaults and are then passed to the {@link get_posts()}

|
|
|

* 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
|
|
|
267 |
* integer (number), then just the 'post_parent' is grabbed and everything else
|
|
|
268 |
* is lost. If you don't specify any arguments, then it is assumed that you are
|
|
|
269 |
* in The Loop and the post parent will be grabbed for from the current post.
|
|
|
270 |
*
|
|

* 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
|
|
|
273 |
* used to get all of the posts. Giving a number higher than 0 will only

* retrieve that amount of posts.

|
|
|
278 |
* post types are 'post', 'pages', and 'attachments'. The 'post_status'

* Builds an object with all post type capabilities out of a post type object
|
|
|
1341 |
*
|
|
|
1342 |
* Post type capabilities use the 'capability_type' argument as a base, if the
|
|
|
1343 |
* capability is not set in the 'capabilities' argument array or if the
|
|
|
1344 |
* 'capabilities' argument is not supplied.
|
|
|
1345 |
*
|
|
|
1346 |
* The capability_type argument can optionally be registered as an array, with
|
|
|
1347 |
* the first value being singular and the second plural, e.g. array('story, 'stories')
|
|
|
1348 |
* Otherwise, an 's' will be added to the value for the plural form. After
|
|
|
1349 |
* registration, capability_type will always be a string of the singular value.
|
|
|
1350 |
*
|
|
|
1351 |
* By default, seven keys are accepted as part of the capabilities array:
|
|
|
1352 |
*
|
|
|
1353 |
* - edit_post, read_post, and delete_post are meta capabilities, which are then
|
|
|
1354 |
* generally mapped to corresponding primitive capabilities depending on the
|
|
|
1355 |
* context, which would be the post being edited/read/deleted and the user or
|
|
|
1356 |
* role being checked. Thus these capabilities would generally not be granted
|
|
|
1357 |
* directly to users or roles.
|
|
|
1358 |
*
|
|
|
1359 |
* - edit_posts - Controls whether objects of this post type can be edited.
|
|
|
1360 |
* - edit_others_posts - Controls whether objects of this type owned by other users
|
|
|
1361 |
* can be edited. If the post type does not support an author, then this will
|
|
|
1362 |
* behave like edit_posts.
|
|
|
1363 |
* - publish_posts - Controls publishing objects of this post type.
|
|
|
1364 |
* - read_private_posts - Controls whether private objects can be read.
|
|
|
1365 |
*
|
|
|
1366 |
* These four primitive capabilities are checked in core in various locations.
|
|
|
1367 |
* There are also seven other primitive capabilities which are not referenced
|
|
|
1368 |
* directly in core, except in map_meta_cap(), which takes the three aforementioned
|
|
|
1369 |
* meta capabilities and translates them into one or more primitive capabilities
|
|
|
1370 |
* that must then be checked against the user or role, depending on the context.
|
|
|
1371 |
*
|
|
|
1372 |
* - read - Controls whether objects of this post type can be read.
|
|
|
1373 |
* - delete_posts - Controls whether objects of this post type can be deleted.
|
|
|
1374 |
* - delete_private_posts - Controls whether private objects can be deleted.
|
|
|
1375 |
* - delete_published_posts - Controls whether published objects can be deleted.
|
|
|
1376 |
* - delete_others_posts - Controls whether objects owned by other users can be
|
|
|
1377 |
* can be deleted. If the post type does not support an author, then this will
|
|
|
1378 |
* behave like delete_posts.
|
|
|
1379 |
* - edit_private_posts - Controls whether private objects can be edited.
|
|
|
1380 |
* - edit_published_posts - Controls whether published objects can be edited.
|
|
|
1381 |
*
|
|
|
1382 |
* These additional capabilities are only used in map_meta_cap(). Thus, they are
|
|
|
1383 |
* only assigned by default if the post type is registered with the 'map_meta_cap'
|
|
