I also had the problem (Magento 1.4.1.1) with the “return parent::_prepareLayout();” creating a “Home” link at the end of the breadcrumb path.

To fix I just extended Mage_Core_Block_Template class instead of Mage_Catalog_Block_Breadcrumbs. Then I added the public function “getTitleSeparator($store = null)” to my new class to keep it working. That way you are using a completely different method instead of inheriting the Mage_Catalog_Block_Breadcrumbs as parent, which adds a “home” link by default.

It is a shame that the [Breadcrumbs-A] script does not support a deleteCrumb method, or for that matter an entire CRUD methdology for manipulating crumbs. ie. Create, Read, Update, Delete. It could be an idea for a module override, but personally I would like to see that type of functionality implemented in the core.

As a side note I note the addCrumb method has a boolean parameter to insert a crumb “$after”, however it is just a parameter in the function and has no influence as it is not actually implemented.

Hello,

If i wanted to override method of continue shopping button, how can i do that.
Location : /app/core/Mage/Checkout/Block/Cart.php
public function getContinueShoppingUrl()
{
$url = $this->getData(’continue_shopping_url’);
if (is_null($url)) {
$url = Mage::getSingleton(’checkout/session’)->getContinueShoppingUrl(true);
if (!$url) {
$url = Mage::getUrl();
}
$this->setData(’continue_shopping_url’, $url);
}
return $url;
}

great tutorial but if you use Firebug, won’t all make it easier?

It works (!) with Magento 1.4.0.1.

But when I go to “Configuration->Advanced” and set “Disabled” for Fido_Catalog original Breadcrumbs does not appear.
So I can’t swith off this module. Why?..

It does not work in 1.4.1. I guess you can’t overwrite (untested) a block class that is created like this.
$this->getLayout()->createBlock(’catalog/breadcrumbs’);
Mage/Catalog/Block/Category/View.php
Mage/Catalog/Block/Product/View.php
