Magento – Show breadcrumb on product details page

breadcrumbsseo

I'm customizing rwd theme. I'm not able to show breadcrumb on product page.

In admin breadcrumb is enabled for CMS pages. Inside rwd/default/layout/page.xml

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

is present.
Even I tried adding

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

to default handle in page.xml

Inside catalog/product/view.phtml I've tried following codes

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

and

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

Still it's not appearing on product page.

Best Answer

In default rwd theme the breadcrumbs are coming on product details page.

Check at Template file:

Basically magento calls the breadcrumb in root template files 1column.phtml, 2columns-left.phtml etc. using the code <?php echo $this->getChildHtml('breadcrumbs') ?> .

Check at page.xml

And on page.xml it defines the breadcrumb block. You need to check this at thing on product details page.

Check at other layout file:

You need check any layout code that might remove the breadcrumb using below code:

<catalog_product_view>
...
<remove name="breadcrumbs" />
...
</catalog_product_view>

<catalog_product_view>
...
<reference name="root"> 
....               
    <action method="unsetChild"><name>breadcrumbs</name></action>
...    
</reference>
...

Magento – Full breadcrumb in product listing page

Assuming your product only belongs to one category. You could override the getBreadcrumbPath function in Mage_Catalog_Helper_Data in this way:

if (!$this->_categoryPath) {

   $path = array();
   $category = $this->getCategory();

   if(!$category && $this->getProduct()) {

      $categoryIds = $this->getProduct()->getCategoryIds();
      if (is_array($categoryIds) and count($categoryIds)) 
          $category = Mage::getModel('catalog/category')->load(array_pop($categoryIds));
   }

   if ($category) {
   ...

Untested, but it should work

Magento 1.7 – How to Remove Part of Breadcrumb from Category and Product Page

It would be wiser to rewrite the Mage_Catalog_Helper_Data, as it provides the data on what categories will be added to breadcrumbs.

Assuming you know how to rewrite that helper class, here's what you have to do:

Rewrite the class Mage_Catalog_Helper_Data.
Override getBreadcrumbPath method.

Copy the original method but modify these lines:

// add category path breadcrumb
foreach ($pathIds as $categoryId) {
    if (isset($categories[$categoryId]) && 
        $categories[$categoryId]->getName() &&
        $categoryId != $YOUR_CATEGORY_ID // Notice the extra category check here...
    ) {
        $path['category'.$categoryId] = array(
            'label' => $categories[$categoryId]->getName(),
            'link' => $this->_isCategoryLink($categoryId) ? $categories[$categoryId]->getUrl() : ''
        );
    }
}

Replace $YOUR_CATEGORY_ID variable or set a value for it.

EDIT:

In case you don't know how to do a class rewrite

Open the file Mage_Catalog_Helper_Data.
Find the method getBreadcrumbPath. It starts with something like public function getBreadcrumbPath()

Replace the whole method with this code:

public function getBreadcrumbPath()
{
    if (!$this->_categoryPath) {

        $path = array();
        if ($category = $this->getCategory()) {
            $pathInStore = $category->getPathInStore();
            $pathIds = array_reverse(explode(',', $pathInStore));

            $categories = $category->getParentCategories();

            !$category_ids_to_remove = array(YOUR_CATEGORY_ID_1, YOUR_CATEGORY_ID_2);
            // add category path breadcrumb
            foreach ($pathIds as $categoryId) {
                if (isset($categories[$categoryId]) && 
                    $categories[$categoryId]->getName() &&
                    !in_array($categoryId, $category_ids_to_remove) // Notice the extra category check here...
                ) {
                    $path['category'.$categoryId] = array(
                        'label' => $categories[$categoryId]->getName(),
                        'link' => $this->_isCategoryLink($categoryId) ? $categories[$categoryId]->getUrl() : ''
                    );
                }
            }
        }

        if ($this->getProduct()) {
            $path['product'] = array('label'=>$this->getProduct()->getName());
        }

        $this->_categoryPath = $path;
    }
    return $this->_categoryPath;
}

Replace the text YOUR_CATEGORY_ID to the actual category ID of the category you want to hide. It should work after that.

Please take note that rewrite core classes is extremely not recommended as core files are replaced whenever you update your magento.
