function drupal_get_filename
Same name in other branches
- 7.x includes/bootstrap.inc \drupal_get_filename()
- 8.9.x core/includes/bootstrap.inc \drupal_get_filename()
Returns and optionally sets the filename for a system resource.
The filename, whether provided, cached, or retrieved from the database, is only returned if the file exists.
This function plays a key role in allowing Drupal's resources (modules and themes) to be located in different places depending on a site's configuration. For example, a module 'foo' may legally be located in any of these three places:
core/modules/foo/foo.info.yml modules/foo/foo.info.yml sites/example.com/modules/foo/foo.info.yml
Calling drupal_get_filename('module', 'foo') will give you one of the above, depending on where the module is located.
Parameters
$type: The type of the item; one of 'core', 'profile', 'module', 'theme', or 'theme_engine'.
$name: The name of the item for which the filename is requested. Ignored for $type 'core'.
$filename: The filename of the item if it is to be set explicitly rather than by consulting the database.
Return value
string The filename of the requested item or NULL if the item is not found.
Deprecated
in drupal:9.3.0 and is removed from drupal:10.0.0. Use \Drupal\Core\Extension\ExtensionPathResolver::getPathname() instead.
