这确实是一个错误，可能是由于child_of 论点

因为child_of 请求给定页面的整个子树（不仅是直接子树，还包括这些子树的子树等等），WordPress首先查询所有页面和then selects a subset of those pages. 第一个查询尊重订单，但the second subselection messes this up by just using array_merge().

我有created a Trac ticket for this.

搜索解决方案时的一些旁注：

通读this ticket at trac, 参数将随即将发布的版本而更改，以与get_posts() 参数

你确定你没有使用\'include\' 作为论据？此设置\'child_of\' 归零

function wpse16921_get_pages( $pages, $r )
{
    echo \'<pre>\'; print_r($pages); echo \'</pre>\';
}
add_filter( \'get_pages\', \'wpse16921_get_pages\' );

// First: Loop through your pages inside the filter
function wpse16921_get_pages_filter( $pages, $r )
{
    # echo \'<pre>\'; 
        foreach ( $pages as $page )
        {
            $page = (array) $page;
            $pages_temp[$page[\'post_date\']] = $page;
        } 
        # echo \'Before manipulation: \'; print_r($pages_temp);
        $pages_temp = \'/* handle sorting of your new date keys over here */\';
        # echo \'After manipulation: \'; print_r($pages_temp);
    # echo \'</pre>\';

    return $pages = $pages_temp;
}

// Second: Attach the filter to the appropriate hook
function wpse16921_get_pages_filter_hook()
{
    add_filter( \'get_pages\', \'wpse16921_get_pages_filter\', 10, 2 );
}
add_action( \'after_setup_theme\', \'wpse16921_get_pages_filter_hook\', 0 );

// Call your pages
function wpse16921_get_pages_call() 
{
    $pages = get_pages();

    # >>>> start modifying/preparing the output
    echo \'<pre>\'; 
        foreach ( $pages as $date => $page )
            echo $date.\'<br />\';     
    echo \'</pre>\';
    # <<<< end modifying/preparing the output
} 
add_action( \'after_setup_theme\', \'wpse16921_get_pages_call\' );

我不知道如何解决WordPress的问题-我得到的结果与您的相同，但这可以通过使用PHP函数来实现sort() 和rsort() 还有一些肮脏的工作foreach.

rsort() 将按相反顺序对数组进行排序sort() 从最低到最高。

尝试以下操作：

<?php 
    $children = get_pages( array( \'child_of\' => 7 ) );

    foreach ( $children as $child ) {
        // get post date of each page/child
        $post_date = $child->post_date;
        // populate the array with the post dates
        $dates[] = $post_date;

    }

    // Sort the array in reverse order
    rsort( $dates ); // or sort( $dates ) for the lowest to highest

    foreach ( $dates as $date ) {

        echo $date;
        echo \'<br />\';

   }
?>

使用get_children 相反-将的子项替换为post\\u父项/sort\\u列/sort\\u顺序-即：

$nav_args = array(
\'sort_column\' => \'date\', 
\'sort_order\' => \'desc\', 
\'post_parent\' => get_the_ID(),
);

$list = get_children( $nav_args ); // list results ##
