我正在尝试在magento的产品页面上显示面包屑，但这给了我一个致命错误

Question

This is the line I have put in catalog/product/view.phtml:

<?php echo $this->getLayout()->getBlock('breadcrumbs')->toHtml(); ?> 

And this is the error I get:

Fatal error: Call to a member function toHtml() on a non-object in ../catalog/product/view.phtml on line 159

Any solutions to this? I am running Magento 1.4.1.1

Answer 1

XML

Make sure you have your configuration setup in your theme's page.xml

<block reference="header">
   <block type="page/html_breadcrumbs" name="breadcrumbs" as="breadcrumbs"/>
</block> 

View

You need to call the HTML item itself

<?php echo $this->getChildHtml('breadcrumbs') ?>

Answer 2

I had this same quandary. I managed to get breadcrumbs on the products page by adding the following to app/design/frontend/THEME/default/layout/calalog.xml

<catalog_product_view translate="label">
    <-- existing content -->
    <reference name="content">
        <-- existing blocks -->
        <block type="catalog/product_view" name="product.info" template="catalog/product/view.phtml">
            <-- existing blocks -->
            <block type="page/html_breadcrumbs" name="breadcrumbs" as="breadcrumbs"/>
        </block>
     </reference>
    <-- existing content -->
</catalog_product_view>

Then in catalog/product/view.phtml add the following where you would like the breadcrumbs to appear.

<?php echo $this->getChildHtml('breadcrumbs') ?>
