Joomla 3.3获取会话变量

Question

in this url (URL SEF Active): www.mysite.com/test/test-test?source=mycampaign

I want to pass the variable (mycampaign)on different pages.

With this code work fine in 2 page:

Page 1 (www.mysite.com/index.php/test/test-test?source=mycampaign):

session_start(); 
$_SESSION['source'] = $_GET['source'];

Page 2

session_start(); 
$source = $_SESSION['source'];

Page 3

session_start(); 
$source = $_SESSION['source'];

When I get to page 3 the variable does not work anymore. The url change this way: www.mysite.com/index.php?option=com_users&view=registration&Itemid=371

this code works perfectly with URL SEF disabled and with url string "&source=mycampaign" instead of "?source=mycampaign"

Can someone help me? Thank you

Answer 1

You can use session instance in Joomla 3 for that.
Page 1:

$session = JFactory::getSession();
$session->set('source',JFactory::getApplication()->input->get('source'));

Page 2 and 3:

$session = JFactory::getSession();
$source = $session->get('source');
