有一个主要职位：

$parent = wp_insert_post([
    \'post_type\' => \'parent\',
    \'post_name\' => \'test parent\'
]);

孩子们：

$child1 = wp_insert_post([
    \'post_type\' => \'child\',
    \'post_name\' => \'test child1\'
]);
$child2 = wp_insert_post([
    \'post_type\' => \'child\',
    \'post_name\' => \'test child2\'
]);
$child3 = wp_insert_post([
    \'post_type\' => \'child\',
    \'post_name\' => \'test child3\'
]);

让我们匹配它们：

wp_update_post(
    array(\'ID\' => $child1, \'post_parent\' => $parent)
);
wp_update_post(
    array(\'ID\' => $child2, \'post_parent\' => $parent)
);
wp_update_post(
    array(\'ID\' => $child3, \'post_parent\' => $parent)
);

最后列出：

$children = get_children([\'post_parent\' => $parent]);

这在理论上似乎是可以的，但它只描述了关系本身，而不是顺序。如果我想命令孩子们怎么办？怎么做？

\'orderby\' => \'date\',
\'order\' => \'DESC\',
