Thanks

You need to modify getBreadcrumbPath() in app/code/core/Mage/Catalog/Helper/Data as links are not added to the breadcrumb array by default.

Do this with a rewrite that would look like

...
<helpers>
 <catalog>
 <rewrite>
 <data>[Vendor]_[ModuleName]_Helper_Catalog_Data</data>
 </rewrite>
 </catalog>
</helpers>
...

in your config.xml and the following would be the rewritten class

class [Vendor]_[ModuleName]_Helper_Catalog_Data extends Mage_Catalog_Helper_Data

 public function getBreadcrumbPath()
 
 parent::getBreadcrumbPath();
 if (array_key_exists('product', $this->_categoryPath)) 
 $this->_categoryPath['product']['link'] = $this->getProduct()->getProductUrl();
 

 return $this->_categoryPath;
 

Observe the proper event, perhaps something similar to (just guessing the event) core_block_abstract_to_html_before, (but perhaps something that would be less often observed) with a custom observer, similar to:

 <core_block_abstract_to_html_before>
 <observers>
 <df2k2_update_breadcrumb>
 <class>df2k2_page/observer</class>
 <method>updateBreadcrumbLink</method>
 </df2k2_update_breadcrumb>
 </observers>
 </core_block_abstract_to_html_before>

Observer Class

 public function updateBreadcrumbLink(Varien_Event_Observer $observer)
 

 $breadcrumbsBlock = $observer->getEvent()->getBlock();

 if ($breadcrumbsBlock instanceof Mage_Page_Block_Html_Breadcrumbs) 
 // Get the block, get the last breadcrumb item in the array
 // and simply check for registry('current_product') or 'current_category',
 // and set the last item's [`link`] element to either the product's url or the categories URL 
 // example,
 if (is_array($breadcrumbsBlock->_crumbs)) 
 end($breadcrumbsBlock->_crumbs);
 $breadcrumbsBlock->_crumbs[key($breadcrumbsBlock->_crumbs)]['link'] 
 = Mage::getRegistry('current_product')->getUrl();
 // = Mage::helper('core')->getCurrentUrl();
 
 $breadcrumbsBlock->assign('crumbs', $breadcrumbsBlock->_crumbs);

 

 return $this;
 

Once you set the link part for the last crumb item in the array of crumbs, then it will automatically render the item to include the linked URL.

There is a lot of detail missing with logic and object checking for current_product and category... Essentially, if there exists a registry for current_product, use that... if current_category, use that... otherwise, simply do whatever you want, or nothing at all.

If you don't wish to look up the details of the product/category.. just get the current URL and set the ['link'] element to the current URL.

<?php if($crumbs && is_array($crumbs)): ?>
<div class="breadcrumbs">
 <ul>
 <?php foreach($crumbs as $_crumbName=>$_crumbInfo): ?>
 <li class="<?php echo $_crumbName ?>">
 <?php if($_crumbInfo['link']): ?>
 <a href="<?php echo $_crumbInfo['link'] ?>" title="<?php echo $this->escapeHtml($_crumbInfo['title']) ?>"><?php echo $this->escapeHtml($_crumbInfo['label']) ?></a>
 <?php elseif($_crumbInfo['last']): ?>
 <?php // i have add link code here as below ?>
 <a href="<?php echo $_crumbInfo['link'] ?>" title="<?php echo $this->escapeHtml($_crumbInfo['title']) ?>"><strong><?php echo $this->escapeHtml($_crumbInfo['label']) ?></strong></a>
 <?php else: ?>
 <?php echo $this->escapeHtml($_crumbInfo['label']) ?>
 <?php endif; ?>
 <?php if(!$_crumbInfo['last']): ?>
 <span>/ </span>
 <?php endif; ?>
 </li>
 <?php endforeach; ?>
</ul>
</div>
<?php endif; ?>
