How to change template path in Joomla CMS?

Question

CMS

You need to write a plugin for Joomla CMS that loads a template from the /template_name/dir_name folder
instead of the standard /template_name.
I can not find where the template files are loaded, in order to change the path, please tell me.

Answer 1

And what will the replacement of the element field give? And what to change it to, I did not quite understand.
I found a solution:
the JDocumentHTML class,
the _fetchTemplate () function
can be useful to someone.

Answer 2

In the #__extensions table find your template and change the element field.
