About using session variables

Hello,
bonjour et bonne année à tous.

I have a problem after updating Flexi.

In my flexitemplate, I put a value in a session variable in category view to use it in item view. It was working nice.

Now, after updating, the session variable is modified when I click on a item for viewing it, like if the template category was called again before going to the item template.

Yet, it is the template item who comes on the screen !How is it possible my session variable is revised by category template when I want to see an item ??

Thanks a lot.

Hello

FLEXIcontent does not overwrite session otherwise Joomla would not work,

what is the session (variable) name used to store your data ?


-- also problem maybe with session variable contents, these are saved into the DB,
some characters may break DB query ?!

Try this:

$conf = base64_encode(serialize($data));
// then set into session

// get from session
$conf = unserialize(base64_decode($conf));

Hello ggppdk, thanks for your answer.

I just put some html code in a session variable. I try whith many name as $_SESSION, $_SESSION and so on.

What I don't understand :

The session variable is filled in category_items.php when I call the category template. In this category views, items are displayed in a list on screen. When I click on a item link for displaying it, the value of my variable session is renewed, like if category_items.php was called again before displaying item view.

An example :
If in category_items.php, I put $_SESSION=time(); and echo $_SESSION; It displays (for exemple !) 456230123.

In item.php, I put echo $_SESSION; When I choose an item for displaying in category view, then $_SESSION is displayed on the item screen. But the value has changed, for exemple 456230154. So, my session variable has been recalculated passing through category_items.php when I call item displaying. My session variable is modified only in category_items.php.

Thanks for your attention.

Hello

-- FLEXIcontent will not overwrite session nor use $_SESSION variable directly

but Joomla will probably overwrite this variable


-- A -- you can try doing
session_start();
before using $_SESSION



-- B -- In Joomla the proper way is:
Code:
// 1. Get a reference to session object $session JFactory::getSession(); // 2. GET/SET a session variable // Set a session variable $session->set('myvariable', 'yes'); // Get a session variable echo $session->get('myvariable');
Regards

Thanks.

I try with the A and B solutions, it exactly the same than i have observed.

The variable session is modified when you click on a item to make it displaying.

So,
or : when a item is to be displayed, category-items.php is reused (it seems no possible, in fact),

or : when you click on item link in category view, category_items.php is played again before leaving to go to item view.

Nothing possible else. It's higtly improbable than Joomla use 'toto' (who is a nickname for jokes) like session variable name, and it's impossible Joomla rewrite it with the same rules that I have defined in category_items.php.

Hello

-- there are data that cannot be stored in the joomla session

i guess something is storing data into the session that makes Joomla DB query to fail
(i mean the DB query used to store session data)




-- To make sure that your data are not the cause of the problem do for this:

For storing:
Code:
//Get session object $session = JFactory::getSession(); // Make data safe for DB storage $mydata_safe = base64_encode(serialize($mydata)); // Store data into session $session->set('myvariable', $mydata_safe, 'myarea');


For retrieving:
Code:
// Get session object $session = JFactory::getSession(); // Get data from session $mydata_safe = $session->get('myvariable', 'default_value', 'myarea'); // Decode / unserialize data $mydata = unserialize(base64_decode($mydata_safe));
