我有一个我买的 Wordpress 主题,它附带了许多不同的小部件。我有一个带有以下代码的代码,它的作用是显示最近的帖子。我需要对其进行更改,实际上是两个,而不是向我显示最近的 POST,我需要它来向我显示最近的投资组合项目,并且只显示某个类别。

<?php

在这一行

<?php $wp_query->query("showposts=". $count ."&category_name=". $querycat); ?>

用。。。来代替

<?php $wp_query->query("showposts=". $count ."&category_name=". $querycat."&post_type=portfolio"); ?>

我有一个和你类似的小部件。在上面的答案的帮助下,我能够让我的工作。希望这会对您或其他人有所帮助。
