WordPress 技巧：显示同个父页面的其他子页面的链接

<?php
global $post;
if($post->post_parent){
    $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
} else {
    $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
}
if ($children) {
    echo '

<ul>';
        echo $children;
    echo '</ul>
';
}
?>
