I am trying to create a session variable in my store index.php variable by using the following piece of code.
Mage::getSingleton('core/session')->setRefer("access");
$refer = Mage::getSingleton('core/session')->getRefer();
But I am getting an error saying.
Fatal error: Call to a member function getModelInstance() on null can anyone kindly let me know, how I can set a session variable in index.php file in magento store.
Edit: As ram charan asked I am adding my complete index.php file code here. I am trying to find country and change the currency type based on that and at the same time I am trying to set a session inside the condition.
<?php
if (version_compare(phpversion(), '5.3.0', '<')===true) {
echo '<div style="font:12px/1.35em arial, helvetica, sans-serif;">
<div style="margin:0 0 25px 0; border-bottom:1px solid #ccc;">
<h3 style="margin:0; font-size:1.7em; font-weight:normal; text-transform:none; text-align:left; color:#2f2f2f;">
Whoops, it looks like you have an invalid PHP version.</h3></div><p>Magento supports PHP 5.3.0 or newer.
