Yang HeHere'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.
>Info: Please note, that new versions of Yii Framework already contain a bulit-in breadcrumbs widget. See this class reference chapter for more information. Information in this article may be, however, usable to build custom one, not descending from bulit-in one.
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 ΒΆ
<?php $this->widget('application.components.BreadCrumb', array(
'crumbs' => array(
array('name' => 'Home', 'url' => array('site/index')),
array('name' => 'Login'),
),
'delimiter' => ' → ', // if you want to change it
)); ?>

<?php
class BreadCrumb extends CWidget
{
public $crumbs = array(); public $delimiter = ' » '; public function run() { foreach($this->crumbs as $key => $crumb) { if(isset($crumb['url'])) $this->crumbs[$key] = CHtml::link($crumb['name'], $crumb['url']); else $this->crumbs[$key] = $crumb['name']; } $crumbs = implode($this->delimiter, $this->crumbs); $this->render('breadCrumb', array('crumbs' => $crumbs)); }}
Auto Breadcrumb Widget
In an attempt to expand on this example, I created a breadcrumb widget that automatically manages some features. Please take a look here for details:

note
I'm hesitant to change this myself as I did not put work into writing this article but I prefer this shorthand way of defining crumbs:
<?php $this->widget('application.components.BreadCrumb', array( 'crumbs' => array( array('Home', array('site/index')), array('Login'), ) )); ?>eg no array keys defined.
nice one
nice explanation.
