Hi mlipscomb,

Try this:

$instance_name = "shown_module_1";
if ( JRequest::getInt("LID") == 123 )  $_SESSION[$instance_name] = true;
if ( @$_SESSION[$instance_name] == true) {
return XXX; // if they entered with LID=123
}
else return YYY; // if they have not entered with LID=123

Replace XXX and YYY with the appropriate module ID numbers.

Hmmm... getInt() should have worked and should be a little more secure as it forces the result to be an integer. But there's nothing very wrong with using getVar() either.

Glad it worked though!

Cheers,
Stephen

hmm, we could try the official Joomla cookie mechanism first, then yes, cookies would work too.

Try this. It worked for me. If it doesn't for you, then perhaps there's something up with your Joomla installation.

$instance_name = "shown_module_1";
$session =& JFactory::getSession();
if ( JRequest::getInt("LID",0) == 123 )  $session->set( "seen", true, $instance_name);
if ( $session->get( "seen", null, $instance_name ) == true) {
  return XXX; // if they entered with LID=123
}
else return YYY; // if they have not entered with LID=123
