Codeigniter: Passing data from controller to view

Question

I want to pass $data from the controller named poll to the results_view however I am getting an undefined variable error.

Answer 1

In simple terms,

$data['a'] in controller becomes $a in your view. ($data won't exist in your view, only the index will become available)

e.g.

Controller:    
$data['hello']='hellow world';

view:
echo $hello;
