Add breadcrumbs in Magento to pages that miss them

Here is one solution on how to add breadcrumbs to pages in Magento that by default do not have breadcrumbs. Recently we had a client that requested a basic breadcrumb to be shown on pages that Magento does not serve breadcrumbs.

<?php
/**
*
* CUSTOM BREADCRUMBS
*
* Adds url breadcrumbs for pages that do not have breadcrumbs by default
*
*/
 
?>
<?php if(is_null($crumbs)): ?>
<?php
 
/**
* NOTE
* On some servers use ->getServer('PATH_INFO')
* and on some ->getServer('ORIG_PATH_INFO')
*/
 
$urlRequest = Mage::app()->getFrontController()->getRequest();
$urlPart = $urlRequest->getServer('ORIG_PATH_INFO');
 
if(is_null($urlPart))
{
$urlPart = $urlRequest->getServer('PATH_INFO');
}
 
$urlPart = substr($urlPart, 1 );
$currentUrl = $this->getUrl($urlPart);
 
//$controllerName = Mage::app()->getFrontController()->getRequest()->getControllerName();
//$controllerName = ucfirst($controllerName);
 
$controllerName = str_replace("/", " ", $urlPart);
$controllerName = str_replace("_", " ", $controllerName);
$controllerName = str_replace("-", " ", $controllerName);
$controllerName = ucfirst($controllerName);
 
?>
<span class="breadcrumbs">
<strong class="float"><?php echo $this->__("You're currently on: ") ?></strong>
<ul class="breadcrumbs">
<li class="home">
<a title="<?php echo $this->__('Go to Home Page') ?>" href="<?php echo $this->getUrl() ?>"><?php echo $this->__('Home') ?></a>
</li>
<li> / </li>
<li class="<?php echo strtolower($controllerName) ?>">
<strong><?php echo $this->__($controllerName) ?></strong>
</li>
</ul>
</span>
<?php endif; /* END OF CUSTOM BREADCRUMBS */ ?>
