Joomla登录页面（如果已登录用户）重定向到主页

Question

I think I'm missing something in the Joomla login behaviour. I read a lot of post but can't find the answer of what I looking for. Let's say you have login page (ie: yoursite.com/login), if you login, Joomla correctly brings you to the target page you choose. The problem is : if you then go back to the login page yoursite.com/login, the redirect doesn't work no more. In fact if you refresh the page the login fields vanish and all it remains is the logout button.

I tried

$user = JFactory::getUser();

if($user->id == 1)
{
// redirect here
}

I tried in Joomla 2.5 and 3.x, the behaviour is the same. Am I missing something?

Answer 1

Because it's not the same layout.

If the user is guest, you are looking at the "default_login.php" layout, which - I gather - is the one you already modified. But if the user is logged, you are looking at the "default_logout.php" layout, which you need to override as well.

Answer 2

Before you redirect to home page or any other page you must called getApplication like this.

$mainframe = JFactory::getApplication();
$user = JFactory::getUser();
if($user->id == 1)
 {
    // redirect here
    $mainframe->redirect('index.php');
 }else{
     // redirect to login page
    $mainframe->redirect('login');
 }
