顯示W(wǎng)ordPress當(dāng)前可用的所有簡(jiǎn)碼（Shortcode）

簡(jiǎn)碼（Shortcode）是WordPress一個(gè)非常有用的功能，你可以先了解 WordPress Shortcode（簡(jiǎn)碼）介紹及使用詳解，今天要說的就是如何在WordPress后臺(tái)顯示所有當(dāng)前可用的簡(jiǎn)碼。

只要使用下面的PHP代碼就可以輸出所有簡(jiǎn)碼：

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

如果你想在WordPress后臺(tái)一個(gè)頁面羅列所有可用簡(jiǎn)碼，下載安裝 view-all-shortcodes 插件，就可以在 后臺(tái) >設(shè)置>View All Shortcodes 下查看 。以下是該插件的所有代碼：
