Magento – issue in Mage::registry(‘current_category’), return only the same value for whole category pages

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;
        }

I would advise never editing core code as it will create issues for you down the road.

This is a database change. 0 comes before 1 and no default value is set for that attribute so 0 will always be selected unless otherwise told.

You need to go into your database, find the "is_active" attribute code (there may be two, only edit the one with the Source Model of "eav/entity_attribute_source_boolean"). In "default_value" add the value of "1".

If you know how to use Queries on phpMyAdmin, that would look like:

UPDATE `eav_attribute` SET `default_value` = '1' WHERE `eav_attribute`.`attribute_code`='is_active' AND `eav_attribute`.`source_model`='eav/entity_attribute_source_boolean';

Make sure to save you changes then try to create a new category. You should see something like this:

Note: Whenever editing a field in the database, you should always make a backup. Also, I did not to extensive testing on this, so you should test this change in a development instance first.
