I am currently developing my first own Joomla content plugin. I'd like to add own CSS to the document object, so I need the path of my plugin.
Of course I can do use something like
$styleSheet = JURI::base(). "plugins/content/<my plugin>/css/mystyle.css
But I'd like to also use some API to find my actual installation path.
Is this possible?
The only API call for adding stylesheets is
$doc = JFactory::getDocument();
$doc->addStyleSheet('path/to/style.css');
You can use the JURI::base() - function to get an absolute path, but it is not necessary.
There is no API-calls for getting the url-path to a plugin or a module, as it it not really needed, the plugin or module are not called directly by this uri anyway.
It is common practice to place style-elements, javascripts etc for plugins, modules and components in the /media-folder. Explore this folder to see how it is done.
