These constants are defined for use in Joomla and extensions:-
|JPATH_ADMINISTRATOR||The path to the administrator folder.|
|JPATH_BASE||The path to the installed Joomla! site.|
|JPATH_CACHE||The path to the cache folder.|
|JPATH_COMPONENT||The path to the current component being executed.|
|JPATH_COMPONENT_ADMINISTRATOR||The path to the administration folder of the current component being executed.|
|JPATH_COMPONENT_SITE||The path to the site folder of the current component being executed.|
|JPATH_CONFIGURATION||The path to folder containing the configuration.php file.|
|JPATH_INSTALLATION||The path to the installation folder.|
|JPATH_LIBRARIES||The path to the libraries folder.|
|JPATH_PLUGINS||The path to the plugins folder.|
|JPATH_ROOT||The path to the installed Joomla! site.|
|JPATH_SITE||The path to the installed Joomla! site.|
|JPATH_THEMES||The path to the templates folder.|
|JPATH_XMLRPC||The path to the XML-RPC Web service folder.(1.5 only)|
These constants are defined in
_path_/includes/defines.php except JPATH_BASE which is defined in
Note: These paths are the absolute paths of these locations within the file system, NOT the path you'd use in a URL.
For URL paths, try using JURI::base().
Difference between JPATH_SITE, JPATH_ROOT, and JPATH_BASE
JPATH_SITE is meant to represent the root path of the JSite application, just as JPATH_ADMINISTRATOR is mean to represent the root path of the JAdministrator application.
JPATH_BASE is the root path for the current requested application.... so if you are in the administrator application:
- JPATH_BASE == JPATH_ADMINISTRATOR
If you are in the site application:
- JPATH_BASE == JPATH_SITE
If you are in the installation application:
- JPATH_BASE == JPATH_INSTALLATION.
JPATH_ROOT is the root path for the Joomla install and does not depend upon any application.
Using JPATH_COMPONENT and JPATH_COMPONENT_ADMINISTRATOR sounds great, but it has one big disadvantage: it immediately breaks all attempts to reuse the model from another component. That's something to keep in mind.
