Get session variables between template files

Question

I have set the array in magento session in one of the template file using following code

 Mage::getSingleton('core/session')->setData('filterarray',$filtercatarray);

I'm getting correct value in same template file but when i'm calling same session using following code in another template file i'm getting old session values.

$session = Mage::getSingleton("core/session",  array("name"=>"frontend"));
$catarray = $session->getData('filterarray');

When i'm refreshing the page i'm getting update session value. why i'm not getting update value in first call in another template file?

Answer 1

Clear session value below code may be help you

 $session = Mage::getSingleton("core/session",  array("name"=>"frontend"));
    $catarray = $session->getData('filterarray');
    Mage::getSingleton('core/session')->unsData();
