The Current default functionality of magento is that it shows the recently viewed products on right side of category page. Now I would like to display the same content on at the bottom of product page. the phtml file used is named at location as
frontend/base/default/template/reports/product_viewed.phtml.
Is there any simple way to do it ?
In your theme you will modify the catalog.xml file (/app/design/frontend/{your theme}/default/layout/catalog.xml). Find the following section and add a block call for the template towards the bottom of the content reference.
<catalog_product_view translate="label">
<reference name="content">
<block type="reports/product_viewed" name="product.recently.viewed" as="product_recently_viewed" template="reports/product_viewed.phtml"/>
</reference>
</catalog_product_view>
Then you need to modify your theme for where you want the block to show up. In /app/design/frontend/{your theme}/default/template/catalog/product/view.phtml add the following line where you want the Recently Viewed products to show up.
<?php echo $this->getChildHtml('product_recently_viewed') ?>
That will get it to show but you may need to tweak the template a bit because it is designed for the left column and may not layout properly if you insert it into the middle one.
