How to avoid errors in view when I am using variable for the php session

As said by demedes, you get that error since the item doesn't exist. Use the following code to check whether the item exists or not. You should also note that plain PHP sessions don't work with CodeIgniter by default.

Code:

<?php
if(isset($_SESSION['some_key'])) {
    echo $_SESSION['some_key'];
}
else
{
    $_SESSION['some_key'] = 'some value';
}
?>
