The "J1.5" namespace is an archived namespace. This page contains information for a Joomla! version which is no longer supported. It exists only as a historical reference, it will not be improved and its content may be incomplete and/or contain broken links.

In a standard installation of Joomla! 1.5 we have several predefined events which, when triggered, call functions in the associated plugins.

The user events are divided into two parts. First we have the events used while authentication of a user takes place:

  • onLoginUser
  • onLogoutUser
  • onAuthenticate
  • onAuthenticateFailure

Second we have the events triggered during user management:

  • onBeforeStoreUser
  • onAfterStoreUser
  • onBeforeDeleteUser
  • onAfterDeleteUser

onLoginUser[edit]

Description[edit]

This event is triggered after the user is authenticated against the Joomla! user-base.

If you need to abort the login process (authentication), you will need to use onAuthenticate instead.

Parameters[edit]

  • $user - an associative array of JAuthenticateResponse type (see link for array keys)
  • $options - an associative array containing these keys: ["remember"] => bool, ["return"] => string, ["entry_url"] => string

Boolean

onLogoutUser[edit]

This event is triggered before the user is logged out of the system. If one plugin returns false, the global logout fails. (needs verification)
