}

 }

My view is

I am using the "$data" in the view-load, but i keep getting this message, why?

Answer 1

The keys you put into the $data inside your controller will became variables (with extract()) in your views. So in your example, the:

// controller
$data['title'] = 'hello world';

Will be available in your view as:

// view
<?php print $title ?>

You don't need to prefix everything with $data in your views.
