我正在打电话comments_template(); 从插件文件。具体来说player.php 插件中的文件All Video Gallery. 下面是文件本身。

我尝试添加comments_template(); 就在?> 但什么都没有出现。当它不是主题文件时，是否有其他方法调用该函数？

 comments_template();
 //Loads the comment template. For use in single Post and Page displays. 
 //Will not work outside of single displays unless $withcomments is set to "1".

<?php
global $withcomments;
$withcomments = true;
comments_template();
?>
