PHP / Wordpress : category widget output

本文关键字：小部输出 Wordpress PHP | 更新日期: 2023-09-27

有没有一种方法可以在不修改wordpress核心文件的情况下修改wordpress-classification/archives小部件html输出？例如，我有这样的输出代码：

<aside><h4>Title</h4><ul><li class="cat-item cat-item-11"><a href="#">123</a> (1)</li></ul></aside>

我正在努力实现的目标：

<aside><h4>Title</h4><ul><li class="cat-item cat-item-11"><a href="#">123</a> <span class="number">[1]<span></li></ul></aside>

您有过滤器widget_categories_dropdown_args和widget_categories_args来更改Categories小部件的输出
_{示例：https://wordpress.stackexchange.com/a/25002/12615}

对于Archives小部件，widget_archives_dropdown_args和widget_archives_args
