Show Joomla module to registered users only using code

Most of case you may find that you want to spilit the article content or Joomla page for your logged-in users(registered users) or unregistered users. In this situation below code will helping to separate content to show only for loggin-in user and non-login users(guests).

On the AppClave site, for example, the "Sign In" or "Log In" button in the top right changes to a "My Account" link once the user login is complete(Not for guest visitor).

Joomla User Object Code:

The first thing we'll need to do is define a Joomla variable:

$user = JFactory::getUser();

Which will execute the code in the if statement only for registered users.

$user = JFactory::getUser();
if($user->id > 0) {
// code will display for the registered users only
}

For example you can add Joomla module code like below for display content to registered users only

$user = JFactory::getUser();
if($user->id > 0) {
//
}

Note: Please remove '//' before above 'jdoc' code

If we want to display the content for unregistered users (guests) only, we can check if the user id is equal to 0 instead.

$user = JFactory::getUser();
if($user->id == 0) {
// code will display for the guest users only
}
