通过WordPress插件在目标位置添加HTML代码

I want to write a piece of text through a WordPress plugin in HTML theme between post and comments section.

I want to know is there any way that I can do this no matter what theme is installed and I can show my message between comments section and posts content.

Let me know as soon as possible.

Whatever theme you are using there must be a file in the name comments.php to display commenting section. To find this file open \wp-content\themes\YOUR_THEME\comments.php. Here you can your message wherever you want.
