Here's a simple way to create a breadcrumb widget to be used in your templates. The idea is just to isolate how the breadcrumb is generated based on an array of crumbs.

components/BreadCrumb.php:

<?php
class BreadCrumb extends CWidget {
	
	public $crumbs = array();
	public $delimiter = '/';
	
	public function run() {
		$this->render('breadCrumb');
	}

}
?>

components/views/breadCrumb.php:

<div id="breadCrumb">	
	<?php 
	foreach($this->crumbs as $crumb) {
		if(isset($crumb['url'])) {
			echo CHtml::link($crumb['name'], $crumb['url']);
		} else {
			echo $crumb['name'];
		}
		if(next($this->crumbs)) {
			echo " {$this->delimiter} ";
		}
	}
	?>
</div>

Usage in views ¶

<?php $this->widget('application.components.BreadCrumb', array(
  'crumbs' => array(
    array('name' => 'Home', 'url' => array('site/index')),
    array('name' => 'Login'),
  ),
  'delimiter' => '&rarr;', // if you want to change it
)); ?>
