Question

我会尽力说出最好的话：

我的博客主页有4个＆＃34;最新来自:(一个类别）＆＃34;由4个不同类别提供，每个类别显示2个帖子。我发现了do_not_duplicate方法并使用它来防止它们中的任何一个出现两次（因为作者在每个帖子上使用多个类别来填充我们的博客）。这很好用，但这是我的下一期：

如果一个帖子有多个类别填充主页，它只会在一个类别中发布而不会重复（按照需要），但它现在的另一个类别只显示1个帖子，我在哪里喜欢它显示2.自第二次失踪＆＃39;如果重复被隐藏，我会想知道如何在该类别中显示 next （3rd）帖子。

这是我目前的代码：

不确定这是否会有所帮助，但看起来您需要重置query_posts();以使其再次运行

每次<?php endwhile;?>之后，您都会添加

     <?php wp_reset_query(); ?>

https://codex.wordpress.org/Function_Reference/wp_reset_query

引用： wp_reset_query()将$wp_query和全局发布数据还原到原始主查询。如果必须使用该功能，则应在query_posts()之后调用此函数。如下面的示例所示，强烈建议在查询之前使用pre_get_posts过滤器来更改查询参数。

使用wp_reset_query或WP_Query后无需调用get_posts，因为这些不会修改主查询对象。而是使用wp_reset_postdata。

在＆＃39; do_not_duplicate []＆＃39;之后显示下一篇文章阻止人们展示
