Joomla：现有会话变量在登录后消失了

Question

I have a multi page form in a component. It's for the user not necessary to log in at first. But if they want to save the result they need to log in at one point.

I save the model in a session so I can access it on any page:

$session =& JFactory::getSession();
$session->set( 'model', serialize($model) );

and read it out with:

$session =& JFactory::getSession(); 
$model = unserialize($session->get( 'model', 'empty' ));

This works well, but if I login on the page the current session is cleared and only filled with log in information afterwards.

I checked different sources but the only thing what I find is that the session is cleared at log out, but not at log in.

Can anybody tell my where this behavior comes from? And how I can fix it?

Answer 1

Why not avoid the issue in the first place and use a cookie? You can read and write cookies directly on the backend if you want so you don't have to rewrite any logic beyond the saving/ reading of the cookies.
