WordPress-产生按标签和类别过滤的帖子列表 [英] WordPress - producing a list of posts filtered by tag and then category

问题描述

我正在尝试制作一个在页面上有六个列表的WordPress网站，每个列表显示来自不同类别的帖子.很简单.

I'm trying to make a WordPress site that has six lists on a page, each list showing posts from a different category. Simple.

但是，如果用户选择一个标签，将其带到该标签存档页面，我希望他们仍然看到六列表模板，但是每个类别中的所有帖子也会被该标签过滤.因此，帖子列表首先按标签过滤，然后按类别过滤.

But then, if a user selects a tag, taking them to that tag archive page, I want them to still see the six-list template, but all the posts within each category are also filtered by the tag. So lists of posts are filtered first by tag, and then by category.

据我所知，无法使用query_posts或其他任何方式来执行此操作，它需要更高级地使用数据库，但是我不知道如何执行此操作！我认为这里也有类似的问题，但是因为我对PHP知之甚少，而对MySQL却不了解，所以我无法理解答案！

As far as I can tell, there is no way of doing this using query_posts or anything, it needs more advanced use of the database, but I have no idea how to do this! I think that there's a similar question on here, but because I know very little PHP and no MySQL, I can't make sense of the answers!

推荐答案

对，我终于找到了一个相对简单的解决方案.

Right, I have finally found a relatively simple solution to this.

WordPress中有一个错误，无法同时查询类别和标签，因此query_posts('cat=2&tag=bread');不起作用，但是一种解决方法是query_posts('cat=2&tag=bread+tag=bread');神奇地起作用.

There's a bug in WordPress preventing a query of both category and tags working, so query_posts('cat=2&tag=bread'); wouldn't work, but a way around this is query_posts('cat=2&tag=bread+tag=bread'); which magically works.

在tag.php模板中，我希望它从该存档中拾取标签，所以我必须这样做:

In a tag.php template, I wanted it to pick up the tag from that archive, so I had to do this:

<?php query_posts('cat=12&tag='.$_GET['tag'].'+'.$_GET['tag']); ?>

效果很好.
