Help for how to show the title in browser title

[eluser]margsot[/eluser]
Hi i am using code igniter for my website and i have a little problem.

In my view file userpost.php i am using this code to show the description of the users uploaded image.

Code:

<?php echo $postDetails->description;?>

Due to SEO reasons i want this description to appear on the browser title.

Inside the controller file board.php i use this code

Code:

$data['title'] = 'Post Details page';

and in the browser title appears "Post Details page"

I tried to change the code above from

Code:

$data['title'] = 'Post Details page';

to

Code:

$data['title'] =$postDetails->description;

and i thought that the browser title will now get the description of the image but didn't work.

I cant understand why this isnt working !!!
Can someone please help me?

Thanks
