Magento 1.9 Static Banner – How to Display on Top of Product Page

The products that are passed by the collection to the list view only contain the basic attributes, description and price are not included. The easiest thing to is to instantiate the product model and pull the attributes you need with ->getData('attribute').

example:

$product_attr = Mage::getModel('catalog/product')->load($_product->getId());

then you will get your attributes by replacing:

<?php echo $_product->getDescription(); ?>
<?php echo $_product->getPrice(); ?>

with :

<?php echo $product_attr->getData('description'); ?>
<?php echo $product_attr->get('price'); ?>

Although, the recommended way to do it, is to add an observer to the 'catalog_block_product_list_collection' event and add those attributes to the collection

Did you check that the information exist on the DOM, if it is then you probably need to change the query, when you are using an ID (#) selector on jQuery it will only grab the first element that it finds that matches that query you can add specificity to the query by adding an scope the element that you want to show.

try changing the your selector to affect an element that falls within the scope of the element that is triggering the event something simple like:

  jQuery('.product-image')
                    .mouseover(function () {
                        jQuery('#hidden_image', $(this)).show();
                    })
                    .mouseout(function () {
                        jQuery('#hidden_image', $(this)).hide();
                    })

The problem here is, when you are loading your product page directly, Mage::registry('current_category') will return NULL and thus nothing will get executed in your code, since all of your code resides in that parent if loop checking.

You can use below code.

<?php
    $_imgHtml = '';
    $_imgUrl  = false;

    //check whether a valid category exist
    if(Mage::registry('current_category')) {

        //grabing category banner if any
        $_category=Mage::registry('current_category');
        $_helper    = Mage::helper('catalog/output');
        if ($_imgUrl = $_category->getImageUrl()) {

            //prepare banner html
            $_imgHtml = '<p class="category-image"><img src="'.$_imgUrl.'"     alt="'.$this->escapeHtml($_category->getName()).'" title="'.$this->escapeHtml($_category->getName()).'" /></p>';
            $_imgHtml = $_helper->categoryAttribute($_category, $_imgHtml, 'image');
        }
    }

    //check a valid image url exist
    if ($_imgUrl) {
            echo $_imgHtml;
    } else {
        echo $this->getLayout()->createBlock('cms/block')
            ->setBlockId('cms_top_banner')
            ->toHtml();
    }
?>

This will make sure, if a valid category does not exist, it will show your default banner in any case.
