WordPress函数:get_sidebar

一、函数简介

引入当前主题的模板文件 sidebar.php 。如果使用特定的名字 ($name) ,那么就会引用包含这个特定名字的模板文件 sidebar-{name}.php 。

如果主题没有 sidebar.php 文件,就会引入默认的 wp-includes/theme-compat/sidebar.php 。

<?php get_sidebar( $name ); ?>

二、函数参数

  • $name (string) (可选) 调用 sidebar-name.php. 默认: None

三、函数案例

(一)、404页面

下面的代码是一个简单模板文件,专门用来显示 "HTTP 404: Not Found" 错误的 (这个文件应该包含在你的主题中,名为 404.php)

<h2>Error 404 - Not Found</h2>
<?php get_sidebar(); ?>
