Get session information of logged-in user

Question

I recently started playing with Joomla. So I found out that Joomla has a built-in user creation and log-in system even for the users of the front site. So I was wondering, what is the way to retrieve the details of a user's session, most importantly the username, and any other one, to produce personalized content,e.g. in a php script, when that user makes a request to the site?

Answer 1

To get the details of a logged in user use:

$user = JFactory::getUser();

The $user variable will contain your needed information from the database, e.g.:

$email = $user->email;

Use var_dump($user); to see what other fields you have available.
