75 | * does not mean that it won't work on posts. It is recommended that you know
|
---|
76 | * what context you wish to retrieve the children of.
|
---|
77 | *
|
---|
78 | * Attachments may also be made the child of a post, so if that is an accurate
|
---|
79 | * statement (which needs to be verified), it would then be possible to get
|
---|
80 | * all of the attachments for a post. Attachments have since changed since
|
---|
81 | * version 2.5, so this is most likely unaccurate, but serves generally as an
|
---|
82 | * example of what is possible.
|
---|
83 | *
|
---|
84 | * The arguments listed as defaults are for this function and also of the
|
---|
85 | * {@link get_posts()} function. The arguments are combined with the
|
---|
86 | * get_children defaults and are then passed to the {@link get_posts()}
|
---|
87 | * function, which accepts additional arguments. You can replace the defaults in
|
---|
88 | * this function, listed below and the additional arguments listed in the
|
---|
89 | * {@link get_posts()} function.
|
---|
90 | *
|
---|
91 | * The 'post_parent' is the most important argument and important attention
|
---|
92 | * needs to be paid to the $args parameter. If you pass either an object or an
|
---|
93 | * integer (number), then just the 'post_parent' is grabbed and everything else
|
---|
94 | * is lost. If you don't specify any arguments, then it is assumed that you are
|
---|
95 | * in The Loop and the post parent will be grabbed for from the current post.
|
---|
96 | *
|
---|
97 | * The 'post_parent' argument is the ID to get the children. The 'numberposts'
|
---|
98 | * is the amount of posts to retrieve that has a default of '-1', which is
|
---|
99 | * used to get all of the posts. Giving a number higher than 0 will only
|
---|
100 | * retrieve that amount of posts.
|
---|
101 | *
|
---|
102 | * The 'post_type' and 'post_status' arguments can be used to choose what
|
---|
103 | * criteria of posts to retrieve. The 'post_type' can be anything, but WordPress
|
---|
104 | * post types are 'post', 'pages', and 'attachments'. The 'post_status'
|
---|
105 | * argument will accept any post status within the write administration panels.
|
---|
106 | *
|
---|
