The documentation for J3 instructs using Factory::getApplication('site') to get the site application, however according to the documentation for J4 doesn't have those method parameters anymore.

I'm working on a plugin that requires some file from my site template and aside from a database query, how can I get that template name? Is there a Factory::getSiteApplication() or anything?

    Do you need this functionality to work in backend?

To specifically call the site application, you can use:


In Joomla 4, getApplication() will always return the global application object and doesn't take any arguments.


The Joomla 4 core com_content component uses Factory::getApplication()->isClient('site');

See: https://github.com/joomla/joomla-cms/blob/4.0-dev/administrator/components/com_content/src/Extension/ContentComponent.php line 137

  • That's only to check if isClient('site') has little to do with my question.
