At this time, CodeIgniter (1.3.3) does not support fragment caching. To overcome this limitation, here is a technique that can be used in the event that you do need a fragment caching feature.
This technique involves breaking out a fragment into its own method, and from within the main view, referencing the URL of the fragment with a require() statement.
controllers/fragment.php
<?php
class Fragment Extends Controller {
function Fragment() {
parent::Controller();
}
function index() {
$data['current_time'] = date('U');
$this->load->view('time_view',$data);
}
function cached_time() {
$this->output->cache(10);
$data['cached_time'] = date('U');
$this->load->view('cached_time_view',$data);
}
}
?>
views/time_view.php
<p>The current time is: <?=$current_time;?>.</p>
<?php require('http://localhost/index.php/fragment/cached_time');?>
views/cached_time_view.php
<p>The cached time is: <?=$cached_time;?>.</p>
