[Thanks All For Advice] Checking if isset is correct?

The Ternary is great for deciding on which of two possible values to return.
But in this case you are deciding whether or not to take one possible action.

Code:

<?php
if(isset($view['navbar']){
   $this->load->view($view['navbar']);
}

In this particular case the ternary is not needed and a simple if statement is cleaner.
