Category Data – How to Retrieve in Magento 1.8 Catalog

categorymagento-1.8

I use these lines to get the data of a product in the catalog,

// Get product data.
$_helper = $this->helper('catalog/output');
$_product_id = Mage::registry('product')->getId();
$_product = Mage::getModel('catalog/product')->load($_product_id);

What about if I want to get the data of a category in the catalog?

$_helper    = $this->helper('catalog/output');
$_category  = $this->getCurrentCategory();
echo Mage::getModel('catalog/category')->load($_category->getId())->getThumbnail();

I get this error,

Fatal error: Call to a member function getId() on a non-object in
…\default\template\page\html\banner-category.phtml on line 4

I tried with these as well but the same error,

$_helper = $this->helper('catalog/output');
$_category_id = Mage::registry('category')->getId();
echo Mage::getModel('catalog/category')->load($_category_id)->getThumbnail();

Any ideas?

Try with this:

$_category = Mage::registry('current_category');
if ($_category) { //you are on the category page
    echo $_category->getThumbnail();
}
else {
    //you are not in a category page
}

Product Attribute

Just add it to this xpath:

/config/frontend/product/collection/attributes

You can find an example here:

/app/code/core/Mage/Catalog/etc/config.xml:718

Category Attribute

Just add it to this xpath:

/config/frontend/category/collection/attributes

You can find an example here:

/app/code/core/Mage/Catalog/etc/config.xml:742

Magento 1.8 – Mage::Registry(‘current_category’) Working in Catalog List but Not in Catalog Product View

Here is the function where it is defined.

It gets the categoryId here:

$categoryId = (int) $this->getRequest()->getParam('id', false);

If that's not in the request path, it won't set 'current_category'.

A product can be in several categories, so when you route to the product directly, it doesn't know the category. There are several ways to find the parent categories of a product, but you will have to find the right method for you. It's easy if you don't put products in more categories but more complex if you do.

   protected function _initCatagory()
        {
            Mage::dispatchEvent('catalog_controller_category_init_before', array('controller_action' => $this));
            $categoryId = (int) $this->getRequest()->getParam('id', false);
            if (!$categoryId) {
                return false;
            }

            $category = Mage::getModel('catalog/category')
                ->setStoreId(Mage::app()->getStore()->getId())
                ->load($categoryId);

            if (!Mage::helper('catalog/category')->canShow($category)) {
                return false;
            }
            Mage::getSingleton('catalog/session')->setLastVisitedCategoryId($category->getId());
            Mage::register('current_category', $category);
            try {
                Mage::dispatchEvent(
                    'catalog_controller_category_init_after',
                    array(
                        'category' => $category,
                        'controller_action' => $this
                    )
                );
            } catch (Mage_Core_Exception $e) {
                Mage::logException($e);
                return false;
            }

            return $category;
        }
