Allows the application to load a custom or default dispatcher.

loadDispatcher(\JEventDispatcher $dispatcher = null) : \Joomla\CMS\Application\BaseApplication

inherited

The logic and options for creating this object are adequately generic for default cases but for many applications it will make sense to override this method and create event dispatchers, if required, based on more specific needs.

since	3.0.0

Arguments

$dispatcher: \JEventDispatcherAn optional dispatcher object. If omitted, the factory dispatcher is created.

Response

\Joomla\CMS\Application\BaseApplicationThis method is chainable.

Allows the application to load a custom or default identity.

loadIdentity(\JUser $identity = null) : \Joomla\CMS\Application\BaseApplication

inherited

The logic and options for creating this object are adequately generic for default cases but for many applications it will make sense to override this method and create an identity, if required, based on more specific needs.

since	3.0.0

Arguments

$identity: \JUserAn optional identity object. If omitted, the factory user is created.

Response

\Joomla\CMS\Application\BaseApplicationThis method is chainable.

Login authentication function.

login(array $credentials, array $options = array()) : boolean|\JException

deprecated

Username and encoded password are passed the onUserLogin event which is responsible for the user validation. A successful validation updates the current session record with the user's details.

Username and encoded password are sent as credentials (along with other possibilities) to each observer (authentication plugin) for user validation. Successful validation will update the current session with the user details.

since	1.5
deprecated	3.2

Arguments

$credentials: arrayArray('username' => string, 'password' => string)
$options: arrayArray('remember' => boolean)

Response

boolean|\JExceptionTrue on success, false if failed or silent handling is configured, or a JException object on authentication error.

Logout authentication function.

logout(integer $userid = null, array $options = array()) : boolean

deprecated

Passed the current user information to the onUserLogout event and reverts the current session record back to 'anonymous' parameters. If any of the authentication plugins did not successfully complete the logout routine then the whole method fails. Any errors raised should be done in the plugin as this provides the ability to give much more information about why the routine may have failed.

since	1.5
deprecated	3.2

Arguments

$userid: integerThe user to load - Can be an integer or string - If string, it is converted to ID automatically
$options: arrayArray('clientid' => array of client id's)

Response

redirect(string $url, string $msg = '', string $msgType = 'message', boolean $moved = false) : void

Optionally enqueues a message in the system message queue (which will be displayed the next time a page is loaded) using the enqueueMessage method. If the headers have not been sent the redirect will be accomplished using a "301 Moved Permanently" code in the header pointing to the new location. If the headers have already been sent this will be accomplished using a JavaScript statement.

since	1.5
deprecated	3.2
see	\JApplication::enqueueMessage()

Arguments

$url: stringThe URL to redirect to. Can only be http/https URL
$msg: stringAn optional message to display on redirect.
