Add my own variable in session

Wednesday 25 February 2009 3:08:25 am

Hi,

I would like to build a tracker on specific class.

I would like to know all the objects of the "software" class the visitor have seen.

I can't find a way to add my own variable in the session. Do you know a good solution ?

Create a temple operator called for example tracksoftware() that would take two parameters:
- function name: 'set' or 'get'
- $node_id (or $object_id, up to your needs).

The core code for the operator should look something like:

$http = eZHTTPTool::instance(); // if it is not there already
$trackSoftwareSessionVariable = 'PaulTrackSoftware';
$operatorValue = false;
if( $function == 'get' )
{
    if( $http->hasSessionVariable( $trackSoftwareSessionVariable ) )
    {
        $operatorValue = $http->sessionVariable( $trackSoftwareSessionVariable );
    }
}
if( $function == 'set' )
{
    $nodeIDArray = array();
    if( $http->hasSessionVariable( $trackSoftwareSessionVariable ) )
    {
        $nodeIDArray = $http->sessionVariable( $trackSoftwareSessionVariable );
    }
    if( !in_array( $nodeID, $nodeIDArray ) )
    {
        $nodeIDArray[] = $nodeID;
    }
    $http->setSessionVariable( $trackSoftwareSessionVariable, $nodeIDArray );
    $operatorValue = true;
}

This may be buggy, but should get you pretty close to where I think you want to get...
