Lobo,

I'm getting the same message with Joomla! 1.5--do you think it could be a similar issue with the j! ftp layer?

Elin:

Is this with the latest 1.8 version. This issue has been fixed for safari3 in the latest 1.8

Spent a few hours tracking this down. I had a 1.5 install which worked while kurund had a 1.5 install on the same machine which did not work Took me a few hours to track this down

joomla/libraries/joomla/session/storage/database.php: function write( )

check for database connected'ness. This fails for mysql but works with mysqli. This has to do with the order of calling destructors and the session write to the database. Here is what drupal's session handler has in comments:

  // Write and Close handlers are called after destructing objects since PHP 5.0.5
  // Thus destructors can use sessions but session handler can't use objects.
  // So we are moving session closure before destructing objects.
  register_shutdown_function('session_write_close');

The reason why forms (and multi-step forms) are affected is because, we follow the POST/GET pattern (http://en.wikipedia.org/wiki/Post/Redirect/Get), so we redirect the browser to a new page and call exit( ) immediately after the "header('Location: ...');" statement. This in turn is supposed to destroy all the PHP objects (in PHP5 and over) and also write the session to the DB. In our current scenario, the session is not written to the db if you use a DSN of mysql://, but does work if you use mysqli://  (not sure why)

I'll point the joomla core developers to this post, and see if we can get this fixed in Joomla-1.5 RC2

The joomla developers are awesome

Got a response from Johan and this is now fixed in svn, so should be part of RC2

If you want a fix before that add the following to:

CRM/Utils/System.php, function redirect( ) (line 410 or so)

change this:

        // replace the & characters with &
        // this is kinda hackish but not sure how to do it right
        $url = str_replace( '&', '&', $url );
        header( 'Location: ' . $url );
        exit( );

to

        // replace the & characters with &
        // this is kinda hackish but not sure how to do it right
        $url = str_replace( '&', '&', $url );
        header( 'Location: ' . $url );
        JSession::close( );
        exit( );
