首先，你可以知道子帖子和父帖子之间的关系，试着找出它，或者试试下面的代码

     $query = new WP_Query( array( 
    \'post_parent\' => get_theID(),
    \'posts_per_page\' => 3, //shows only 3 children. If you want to show all of them, comment this line
));
while($query->have_posts()) {
    $query->the_post();
    /*Output the child markup here*/
    the_content(); //Outputs child\'s content as it is
}
wp_reset_query();
