Question

有没有办法修改wordpress类别/档案小部件html输出而无需修改wordpress核心文件？例如，我有这个输出代码：

<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>

Answer 1

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

对于档案窗口小部件，widget_archives_dropdown_args和widget_archives_args _{示例：https://wordpress.stackexchange.com/q/19945/12615}

    preg_match_all($re, $output, $matches);
