/**
|
|
* Retrieve all children of the post parent ID.
|
|
*
|
|
* Normally, without any enhancements, the children would apply to pages. In the
|
|
* context of the inner workings of WordPress, pages, posts, and attachments
|
|
* 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
|
|
* 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.
|
|
*
|
|
* @see get_posts() Has additional arguments that can be replaced.
|
|
* @internal Claims made in the long description might be inaccurate.
