显示WordPress当前可用的所有简码（Shortcode）

简码（Shortcode）是WordPress一个非常有用的功能，你可以先了解 WordPress Shortcode（简码）介绍及使用详解，今天要说的就是如何在WordPress后台显示所有当前可用的简码。

只要使用下面的PHP代码就可以输出所有简码：

<?php
        global $shortcode_tags;
        echo '
<pre>'; 
        print_r($shortcode_tags); 
        echo '</pre>
';
?>

如果你想在WordPress后台一个页面罗列所有可用简码，下载安装 view-all-shortcodes 插件，就可以在 后台 >设置>View All Shortcodes 下查看 。以下是该插件的所有代码：

<?php

if(is_admin())
