Select the redirection page from the list of menu links offered. Make sure that the link is to a published item.

Note: The same procedure is used for redirecting users on successful logout except you enter the page where you want to redirect successful logouts to where it says "Logout Redirection URL."

If you would like to override the default login specified in your Administration back end from your custom code you can do so with the following:

  • Take the url that you would like to redirect the user to after they have successfully logged in and apply the 'base64_encode' function to it. For example,
$redirectUrl = urlencode(base64_encode($redirectUrl));  
// a base64_encode of index.php?option=com_pizzapie' yeilds: 'aW5kZXgucGhwP29wdGlvbj1jb21fcGl6emFwaWU='
  • Prepend the '&return=' query string to your newly encoded $redirectUrl. For example,
 $redirectUrl = '&return='.$redirectUrl;
  • Append that $redirectUrl to the Joomla Login Url. For example,
              $joomlaLoginUrl = 'index.php?option=com_user&view=login';
              $finalUrl = $joomlaLoginUrl . $redirectUrl;

When you display that $finalUrl, it should look something like this: 'index.php?option=com_user&view=login&return=aW5kZXgucGhwP29wdGlvbj1jb21fcGl6emFwaWU='

The controller.php file in the com_user checks the contents of the 'return' in the JRequest object (the Joomla query access object). If it is set and in the base64 format, it base64_decode(s) it and applies that redirection.
